Be like a Boy Scout I know that our business columnist, Roger Grochmal, talked weather last issue, but coming out of the HRAI conference in August (see page 112) I cannot help but continue that discussion. The number of contractors who self-reported mediocre cooling Welcome aboard Dan Holohan! seasons when asked about their summers is downright depressing. Back around 2000, when I first started writing Without many days above 30 about plumbing and heating systems, one of the first tomes of knowledge that I was told to degrees, Canadians simply were check out was Dan Holohan’s not thinking about their air Pumping Away and other conditioners. And not many really cool piping options for systems were being pushed beyond hydronic systems. Between that, and a few their capacities, so breakdowns of his other classics, I were not happening the way they enjoyed his frank discussions do when the mercury climbs about the realities faced beyond the 35 mark. on the job, as well as his explanations about how to With Environment Canada at odds look at a system, and tackle with The Old Farmer’s Almanac, troubleshooting. it’s anybody’s guess as to how the I am happy to report that we’ve embarked on heating season will kick off (for a new relationship with Dan, opening the door to sharing his knowledge of the history and our pre-season report, see page 24) practical application of the principles of hydronic but I think Roger’s advice is quite heating in the pages of Mechanical Business. prudent. When uncertainty reigns, Be sure to check out his first article for us, on assume the worst and you’ll always page 66, and if you are looking for a copy of any of his books or for a bit of advice about a fare better than what you are system you are working on, drop by his website, prepared for. So I have to ask, is your company prepared for a mild winter? When was the last time you sat down with your management team and front-line people to discuss ways to increase the price per ticket – in ways that your customers will see the extra cost as adding value to their homes rather than pulling dollars from their wallets? Another good to topic for your crew is a discussion about how to re identify and reach new clients. A mention of a humidifier could add comfort and increase your sales. That’s a win-win. Mapping out subdivisions to identify areas with homes in the 15 to 20 year-old range to target them with a flyer drop offe offering a matched air conditioner and furnace combo shak out a few sales that would have otherwise waited could shake until a critical system failure. That keeps your technicians wor working and avoids unhappy homeowners later. It can all help, and it all adds up. And remember, the ones with the most luck tend to be the ones who put in the most prep time. Until next time,

Profile Peter Ashton: Pitching in for the industry

There are two axioms that seem to be guiding principles for Peter Ashton, Masco Canada’s director of trade sales. The first is that an industry is only as strong as its people. The other is that our industry associations are an invaluable resource that can help professionals share information for the betterment of the industry. Recently minted as the chair of the Associate Council at MCAC, Ashton is looking to build on the work of the boards before him to expand the exposure of the council and the mechanical industry, and to entice more members to take an active role.


“Several years ago I was told that you get out of an association what you put into it,” he explained recently as we caught up with him between work meetings and airports. “I sincerely enjoy being involved with the association, and having the opportunity to interact with some really fantastic people.” He was kind enough to share some of his insights into the state of the industry, and thoughts on some of the issues to be faced in the years to come.

How did you get started in the industry? My first job within the industry was with a company called Proceptor. Proceptor manufactured and supplied grease and oil interceptors. Considering I was certified in water and waste water distribution from my time at school, it was a great fit. That was about 18 years ago and I couldn’t see myself in any other industry.


You’ve been in several sectors of the plumbing business. Are there a lot of common issues in each segment of the market?


Being a sales professional within this industry means you have to add value whether you are dealing with an engineer, architect, mechanical contractor, builder or distributor. I believe having experience in both rough and finish plumbing has allowed me to have a better appreciation for plumbing systems and the various challenges experienced by the various influencers involved.

Name: Peter Ashton Title: Director, Trade Sales Company: Masco Canada Age: 39 Resides in: Brampton, Ontario Alma Maters: Sheridan College, University of Guelph Association Involvement: MCAC, CIPH, CSA


What are some of the biggest changes you’ve seen in the industry over the past two decades?


This is the plumbing industry and not much ever changes. In saying that, technology and the internet certainly have had an influence in many aspects of our industry. A good example of this is with Revit. Projects can now be almost completely virtually built before a shovel even hits the ground.


Any thoughts on how the sales environment has changed?


I wouldn’t say that the sales environment has changed much; however I would say that we are all busier and running leaner than ever before, so we need to make sure that a customer’s time is used wisely and you are always adding value. What are some of the challenges facing the industry? One of the concerns I see over the next few years is the retirement of so many people who have helped build the industry to what it is today. They will be taking a wealth of knowledge. I hope that everyone recognizes this and takes the opportunity to learn from them.

ontractors need to stay on top of manufacturers’ latest technologies ies to remain relevant in the heating ng industry, and this is becoming increasingly gly difficult as products are becoming moree technologically advanced. “Every company is designing more advanced products,” says John Goshulak, k, vice-president of sales and marketing at Weil-McLain Canada. “Twenty years ago go if your boiler failed, and it was a pilot assembly that failed or a gas valve, theree were around six different gas valves thatt serviced 100 per cent of the industry.

It’s no longer generic parts.” Technology is helping, to some degree, in this regard too, with more documentation finding its ment that could help tradespeople way online every day, but one development even more in the future would be the integration ntegration of the online world into appliances for the purpose of diagnosing issues with equipment before a technician is on site. “Eventually we’ll be able to dial into a boiler or furnace and say, ‘What’s going on? Let me take a look at the problem.’ That way when the service guy goes there he gets the message,” explains Goshulak, who adds that the technician can arrive with the parts ready to swap. “That doesn’t

Under control Kim Do, heating product manager at Lennox Residential, says control systems have been gaining more popularity due to rising utility costs, and are one way for contractors to generate additional sales. “Homeowners spend, on average, half of their utility bills on heating and cooling their home,” he explains. “By replacing a standard thermostat with a ble, programmable, smart thermostat, homeownerss o can see up to 20 per cent in energy savings and have peace of g mind knowing they have comfort control access, anytime, anywhere in the world.”

Selling on simpler servicing To help alleviate some of the challenges technicians are experiencing with ever-advancing boiler technologies, some companies are focusing on designing boilers that are simpler to service. One method being implemented is to make the boilers serviceable without the use of special tools for such parts as blowers, gas valves and igniters. “You don’t need any special tools anymore, just a basic «ÀœwVˆi˜VÞ]»iÝ«>ˆ˜ÃœÃ…Տ>Ž° Another option available to contractors to make servicing ȓ«iÀ]…iÃ>ÞÃ]ˆÃ̜>ˆ}˜܈̅ëiVˆwV“>˜Õv>VÌÕÀiÀÃ>˜` ܅œiÃ>iÀÃ̜LiVœ“iëiVˆ>ˆâi`ˆ˜ÃiÀۈVˆ˜}ëiVˆwV lines of boilers.

What’s your output?

If you’re pricing tankless units based only on input, it’s like using the wrong end of a hammer Before you pick a non-condensing tankless water heater to save money, check out the total costs. Consider the Navien NPE-S condensing tankless advantages: •More output for the money. With high efficiency condensing technology, NPE-S units deliver more BTUs where it counts, resulting in greater flow rates than comparable units. •Lower installation costs for you. You can typically install a NPE-S in half the time of other tankless units — usually within 4 hours, with more flexibility and lower material costs. •Lower operating costs for the homeowner. Our industry leading 0.99 EF can save the homeowner more on the yearly operating cost. Compare the total costs and you’ll see why Navien is the leader in condensing technology.

And demand for these advanced faucets is not just coming from consumers in Ontario. Wolseley Canada’s Karin DuSange is also experiencing a similar demand.

“We find the touch and touchless faucets are gaining in popularity,” she says. “Our sales of these are greatly increasing, especially over the last year.” DuSange cites the hygienic and water-saving characteristics of these types of faucets as a significant factor in the increased demand.

Kohler now offers kitchen faucets with a sweep spray instead of the traditional circular pattern. The sweep spray is designed to offer a blade of water that helps cut through grease and grime to battle stuck-onfoods, explains Donna Church.

Bar faucets and soap dispensers make any ordinary kitchen look like a more high-end kitchen, he says. Karin DuSange says some consumers are looking for additional features, such as food waste disposers and soap dispensers. These help turn a kitchen sink into a proper work station.


Instant hot water faucets fully integrated with sinks, as well as instant water filters, also make interesting additions, adds Desco’s Diana Di Carlo. continues on page 40

important in new home and renovation projects. She also added that some product lines are changing to match changes to the types of homes being constructed.


“With the consistent demand for condos in and out of the city, products that can meet the demand for small spaces will be vital to design,” she says.


DuSange adds that hands-free faucets are beginning to appear in bathrooms, in addition to kitchens.

Kohler’s Donna Church says Canadian consumers are pretty consistent and generally look for a contemporary design aesthetic, since the style can withstand the test of time.


“They never look dated or out of place,” she says. Moen’s Garry Scott adds that sleek designs with clean lines are in high demand for kitchen faucets in Canada, and that pull-down faucets are extremely popular. “They want a faucet that is a centrepiece,” he says, but functionality still matters. Arcing pullout faucets still dominate sales in her store, reports DuSange. A trend echoed by Desco’s Diana Di Carlo, who says The Water Closet showrooms in Etobicoke are also experiencing high demand for arcing pullout faucets. Also on the consumer demand list is conservation; a trend that Masco’s Krystin Lee says will continue to become increasingly

With the renovation market showing signs of growth this year, and Statistics Canada reporting residential building permits on the rise as well, plumbing product suppliers are hoping that will translate into a solid year for sales. “Our research shows that three quarters of Canadian consumers are spending a bit more this year than last year,” says Garry Scott of Moen. Of those surveyed, about 13 per cent are remodelling their kitchens while 14 per cent are remodelling a bathroom, and Scott says about half will replace their faucets as part of their projects.

HYDRONICS By A ndr e w Sn o o k


e’ve all battled long walks across slippery sidewalks in the midst of winter at one time or another. One could argue it’s a Canadian rite of passage to have your keister kiss the cold ground due to a slip on the ice. But what if our sidewalks could remain dry and snow-free all winter? Impossible? The cities of Saskatoon and Edmonton don’t think so. The City of Saskatoon is considering the possibility of installing snowmelt systems into its downtown city sidewalks since they already plan to tear up the walkways to redevelop them. Edmonton is also exploring this as a possible solution for clearing the snow in its downtown core.

PAVERS VERSUS POURED One factor that needs to be considered when installing a snowmelt system in a city’s sidewalks is the material used to make the sidewalks. For example, since the ideal depth for the tubing is about two inches below the surface, there would be some special accommodations required if pavers are used to build the sidewalk. “Most pavers are three- and four-inches thick and are usually sitting on a sand bed,” explains Leyte. “If you put tubing in the sand below that, the output isn’t going to be as good as if it were embedded right in concrete. The best type of snowmelt system, in my opinion, is right in the finished surface material – the concrete. If a paver style of surface is what is desired, it would be better to go with a stamped patterned concrete instead of actual pavers.”

But what roadblocks exist that could create challenges for using snowmelt for this type of application? Jerry Leyte, Canadian central region sales manager for Uponor, says one of the challenges is convincing the contractors and designers to put insulation underneath the slabs, as well as on the edges of the snowmelt areas. “There are some applications where they can only dig so deep, and they need a certain minimum thickness for the slab, so they feel they don’t have room for insulation. Insulation is obviously an added cost, but if you don’t put it in, it drives the BTU requirement up by roughly one-third.” This means boiler loads would be significantly higher and the end user, i.e. the city, would have to compensate for that. “There are little ways you can increase BTU delivery, with slightly larger diameter pipe and getting better flow to dump more heat into the slab, but ideally you want insulation underneath the slab,” says Leyte.

MANIFOLD LOCATIONS One challenge in creating a snowmelt system for city sidewalks is figuring out where to place all the manifolds. “Sidewalks are long and ongoing so you would have to strategically stagger manifolds at the right places to keep the ideal loop lengths,” explains Leyte. Leyte says the loops can be about 300 feet using 5/8” tubing and 400 feet using 3/4” tubing. In the case of 1” tubing, loops can be upwards of 650 feet. “There’s a certain amount of head pressure per loop that your pumping system can comfortably handle so that you don’t have to oversize the pumps. Longer loop lengths will also minimize the number of manifolds and locations that would be required.” continues on page 46

SIZING AND SPACING FOR SIDEWALKS Uponor’s Jerry Leyte says a snowmelt system for city sidewalks would likely be installed in four- to six-inch thick poured concrete slabs with the tubing g ideally two face and inches from the surface tied to wire mesh, or rebar, and bridged. Although the tube spacing for snowmelt is typically six-inch spacing using 5/8” or 3/4” sized tubing, g, Leyte says using one-inch e-inch tubing to create really lly long loops might be a good fit for snowmelt systems designed for city sidewalks.

For the colder weather in areas like Edmonton and Saskatoon, Leyte recommends a glycol mixture upwards of 40 to 50 per cent to prevent freezing. In the case of city sidewalks, he also suggests a glycol injection system. “If there ever was leakage, the system senses the glycol mix and tops it up, as needed. READY REDUNDANCY In a situation where the snowmelt system is owned by the city, and where there are potential liability issues, having some sensor redundancies in the system can be a worthwhile investment. “If one sensor goes down, you’ve got backups,” explains Leyte. “You may have multiple snowmelt sensors for a given area, and, depending on the control system, you can have the snowmelt system activate as soon as any one of the sensors gets below the setpoint temperature. That way, if one sensor were to fail, the system would still activate properly because of the signal received from any one of the other remaining sensors.”

MAKE IT HOT, BUT NOT TOO HOT… The typical recommendation for a maximum supply water temperature in a snowmelt system is around 150˚F in concrete. Although a higher temperature could melt the snow faster, the shock effect on the concrete needs to be taken into account. “If you try and heat it up relatively quickly, anything over 150˚F always has the risk of shocking the concrete and possibly cracking it and causing damage to the slab,” says Leyte.

This can help avoid slips and falls with pedestrians who become accustomed to the cleared sidewalks. “If people know it’s a snow-melted sidewalk, human nature kicks in and you get a little bit complacent,” explains Leyte. “It may look wet and cleared, but it could be black ice, and therefore dangerous. However, when there’s snow on the sidewalk people tend to be more careful because they know there is a strong likelihood there might be ice underneath it.” continues on page 48

COST AND EFFICIENCY The most cost-effective way to install a snowmelt system is to put in a manual override system, where the user physically turns it on when it snows, and then turns it off when the snowing stops. This may not be very practical, however, since it is dependent on someone watching the weather and knowing when to turn it on and off, particularly in the case of a system designed for sidewalks. “That saves on energy, but the best type of snowmelt system is one that is automated and has the ability to be put in idle mode when there’s no snowfall,” Leyte explains. This allows for the slab to stay partially heated during colder weather – such as -20˚C or -30˚C, when it typically doesn’t snow due to lack of moisture – allowing for much faster response times when the snow begins to fall. This helps prevent fallen snow from accumulating before the snowmelt system kicks in, reducing the chance of a bridging effect taking place, where an air gap is created between the top layer of fallen snow and the surface where the snow is being melted. “It’ll take a long time to melt that type of snow,” explains Leyte. “The system is not meant to melt snow that has accumulated; it’s intended to melt snow as it’s falling.

a system with a proper controller that allows it to go into idle mode allows the sensors to dictate when the system would go on and off.” Temperatures in Edmonton and Saskatoon can get as low as -40˚C. In which case, the snowmelt system wouldn’t be able to keep up with the demand and it would be best if it simply shut down. “That way when it does start to snow and the snowmelt sensor picks up the moisture, it’s already 60 to 70 per cent of the way there, and the response time is going to be a whole lot faster.”

compressor overload

efrigeration installations require overload protection in accordance with the various national and local codes. This overload protection n can be an overload relay, bimetallic (thermal) switch, or motor winding-embedded thermistor network connected to an electronic module. Compressors that use the latter method generally include the words “Thermally Protected” on their nameplate.

Although these methods also offer some level of overload protection for the compressor motor itself, they are primarily intended to prevent overloading of the electrical conductors that feed the compressor. The refrigeration system must be designed with all load and heat sink extremes in mind.

GOING TO EXTREMES The components in a system have factors that could overload the compressor. Here are a few considerations, based on the component parts.

MAXIMUM MOTOR POWER The compressor motor has an upper power limit that must be

The conductors must be sized to accommodate the maximum load at which the equipment will be operated. The electrical code outlines the specifics, but generally speaking the conductors need to be large enough for the application while the branch overload protection must limit the current to protect the electrical conductors from overheating.

power will result in an overload condition which will, in turn, interrupt the process and result in high motor winding temperatures. Ensuring that this does not occur becomes especially important in situations where the compressor is selected at conditions that are close to the maximum saturated suction and discharge temperatures (SST and SDT).

Condenser Sizing The highest load on the condenser will take place when the evaporating pressure and condenser cooling medium temperature are at their maximum values. Where heavy pull-down loads exist, the condenser selection must account for the added heat so as to limit the condensing pressure during maximum design operating conditions.

In applications where the compressor is selected near the maximum SDT limits, it may also be necessary to limit the suction pressure in order to limit the discharge pressure. continued on page 54

We should only apply enough superheating in order to accomplish the task.

Integrating the controls

Setting a new trail for home automation systems

The big appeal for contractors, and homeowners as well, will be the simplicity of it all, says system specialist Tom Cowton. “It’s an easy sell for contractors. This can easily be retrofitted using existing house wires. No new wiring is required. And it’s quite small, but very robust.”



nyone looking to see the latest and greatest in residential home automation might want to take a trip to Thorold, in Southwestern Ontario. That’s where you’ll find the first Canadian Active House, a unique collaboration between numerous building consultants, architect Superkül, and Great Gulf home builders. It’s an important first step in Canada for the concept, and it’s one that, by all accounts, won’t be the last. The Active House concept was originally developed in Denmark, in partnership with academia and industry, bringing together equipment manufacturers with the focus of building energy-efficient buildings that support the well-being and comfort of residents. The Thorold prototype is a fully-integrated residential home that uses advanced home automation technology to increase energy efficiency while optimizing climate control and ventilation. Rolled out by Great Gulf Homes in October of last year, the home uses a Tahoma home automation system that manages more than 80 devices in the structure.

“It was meant to be a prototype for us to study with a view to rolling it out at the local level,” explains Karen Gold, director of marketing for the low rise division of Great Gulf in Toronto. The control system is a gateway controller that uses radio frequency signals to control the window coverings, lights and thermostats. When plugged into the home’s network router, it automatically connects and configures to the home network and locates all of the Z-Wave and RTS wireless controlled devices. According to Tom Cowton, Tahoma system specialist for Somfy Canada in Toronto, the company that integrated the controls, it will easily control more than 40 lighting loads, 23 motorized roller shades, 10 motorized skylights and three thermostats to regulate light and temperature. “Every single switch in that house is an active switch. What this house can do is quite extensive. When it’s all programmed properly, you don’t even realize it’s working for you.”

A LEARNING TOOL The Active House build in Thorold, Ont., is part of a bigger picture that Tom Cowton, Tahoma system specialist for Somfy Canada, explains can help drive the implementation of home technology in the future. “It’s the best of the best as far as carbon footprint goes and is a great case study for HVAC installation and service contractors who might want to know about it,” he says.

Setting, and managing, expectations “I know that keeping contact with customers is important, but what do I need to know about the art of the follow up?” Tom A., Mississauga, Ont. Roger Grochmal is the CEO of AtlasCare in Oakville, Ont. To submit a question about your company, business practices, or the industry in general, send an e-mail to Mechanical Business Magazine’s editor, Adam Freill, adam.freill@

“Inspect what you expect.” These words of wisdom were spoken to me over 35 years ago. They have served me well. When I decided to go out in business on my own, I had been managing some large, complex contracting businesses and I asked myself, “How hard can it be?” I quickly found out that it’s not just about knowledge. Tenacity is a major indicator of success. Good contractors survive through good times and bad because they stay focused and never give in. The most successful contractors are skilled in the art of following up.


M e c h a n i c a l


ailure to follow up is a trait we most often ascribe to sales people because that’s where we see it most often. How often has a sales person lost a sale because they failed to connect back and the customer went elsewhere? In the customer’s mind, the salesman or the company must not need the business or they would have called back. We all lead very busy lives. People trust us to do our jobs and call them back. The secret is to establish the expectation with a customer that you will follow up. Ask them for the best time to contact them, or better yet suggest a time and get their permission. Make it easy for them (and you!) by confirming the correct phone number and ideal time of day for conversation. Then plug it into your calendar and make sure you contact them at the appointed time. The result is that you will build credibility and trust. You are doing what you said you would do. That’s the foundation of trust and people want to do business with people they can trust. Follow up, build trust with your customers and you will have more business. Remember, however, that there is a delicate balance with the art of the successful follow up. Check in too often and you risk annoying your customers. Do it too little, and you’re quickly forgotten. Following up is all about setting and managing expectations with suppliers, customers or staff. Every day over your morning coffee, make a list of the follow ups you plan to do that day. Add a couple of random items to the list to keep everyone on their toes. And remember, following up is a good skill for everyone in your company, not just the owner or manager.

BEYOND SELLING Follow up doesn’t just apply to sales. It can be applied to every part of your business.

Accounts receivable. The procedure is exactly the same. If customers know they can expect a call from you if they don’t pay, they are more likely to give you precedence over someone who doesn’t follow up. Customer service. Connect with customers after a service call or project and ask them how things went. Some call these “happy calls”. Customers will see that you care. It’s a great way to learn about small issues in your company before they become large issues. It’s also a wonderful opportunity to gather quotes and stories that can be used in your marketing. Job sites. Visit work sites to ensure your people are working safely and that they are doing work to the standards you expect. Your crew will see that you manage a tight ship and your customers will feel valued and appreciated that you took the time to stop by.

Suppliers. Make sure suppliers keep their commitments to get parts to you when they say they will. They will work harder on your behalf if they know the follow-up call is coming.

We’re reacting to an ever-changing landscape rather than thoughtfully applying sound principles – the traditional thinking that guided marketing in the last century and will do it in the next century, regardless of how the tools change. To step back from the barrage of tactical options, I ask clients to take a trip with me to the marketing DELI.

What can you do? Visual identity and branding are key means of differentiating. A memorable look differentiates your brand. Of course, it needs to be backed up by delivering on the basic expectations - even a hot pink service van (or just plain hot service tech) won’t cut the mustard if the work doesn’t.

Short instructional videos on anything from how to keep vents clear, to checking windows for heat loss, changing a filter, and lowering the water heater temperature can all be points to play on. And sure, some of you are thinking that all of this information is already out there, but a local spin and some effective marketing can be just the differentiation ticket that you need to connect with your customer base. And wear your locality with a sense of pride. Have you thought about adding value to the community as a whole through a commitment to doing something for neighbours, in addition to doing well for customers? Being the comfort contractor who cares by donating $5 to charity for every service call could be a simple point of differentiation. Some companies differentiate by offering new, different services from their competitors. Some toy with home security, water softeners or IAQ. What about a boldly different approach? Can a contractor contribute other skilled-trade services to homeowners such as electrical and roofing, perhaps through strategic business partnerships? Once you’ve brainstormed your most essential points of difference, it’s important to know if they’re truly compelling and worth the effort. That step is simple – talk to your customers. Engage with them.



The best differentiation adds value. Can you be the YouTuber who records useful weekly “Quick Fix Minute” tips to help customers manage their heating and cooling bills or unclog a toilet with sixty-second demos?

Engagement is another important product in the DELI... more on that next issue.

Commercial piping challenge

A commercial job gets handed to you. Perfect timing as it comes in just ahead of the heating season, and with little A/C this summer, the job fits in with your schedule. You follow the drawings, order your material and get to work installing. On commissioning day, the manufacturers’ reps arrive and go over the job. You have done it according plans and spec, but the rep seems troubled.

1) The rep is concerned with the piping and the connection point. Assuming a 20°F delta T, what is the potential problem? A) The two tees are close together, but they are too close to the 90. B) The pipe size is too small to carry the potential load. C) The boiler piping size is too small. D) All of the above.

4) Is this the best way to pipe this system, knowing there are constant infloor loads, some snowmelt loads and a high temperature air handler load? (The infloor has mixing at the manifold.) A) Yes, but a hydraulic separator would make it easier. B) No. I would pipe it as:

2) The heating boiler was a copper low mass design with a manufacturer-installed boiler circulator on the return. It was directly connected to a series loop piping system. The proper way to pipe a low mass boiler is: A) 2-1/2”, and the system should be at least 3”. B) 2” like the boiler fittings and 2-1/2” for the main. C) 2-1/2” would work throughout. D) None of the above.

A cut above, in tight places!

3) The rep says, “Although I am concerned with the piping size, the real problem is”: A) The piping to the boilers should be reverse-return. B) The supply is before the return, so the boilers have a real potential to short cycle. C) The boilers should be side-by-side. D) The flow switches are mounted vertically.

was looking at a photograph from the construction of Crosley Field, a grand, Cincinnati, Ohio baseball stadium built on the site of League Park, which burned to the ground in 1900. The men in the photo are wearing derbies and loading debris into horse-drawn wagons. In the background, there’s a sign atop a seven-storey building that reads, The Oliver Schlemmer Company – Plumbing, Heating.



Air problems and lack-of-flow problems look pretty much the same. Where there is no flow, there is no heat. You’ll bleed the convector and not get any air. And while you’re bleeding the air that’s not there, you’ll also be affecting the pressure drop between the main and the convector because you’re draining the system. The convector will get hot. It will fool you if you’re not thinking like water. Primary-secondary pumping works the same way. We keep the pressure drop in the piping that’s common to both the primary- and secondary circuits as low as possible and the two circuits hydraulically disconnect. The same goes for low-loss headers. They all owe a debt to delta-P and that simple tee from 1898. Delta-P is the Zen of hydronic heating and making it work for you was the key to success back then. Still is today.


M e c h a n i c a l

Mr. Schlemmer died six years after the fire, and 44 years before I was born, but I’ve known him for a long time. Two years before the fire, he cast a very special tee in that building by the ballpark. He named it the O-S fitting, after himself. The O-S fitting was the first tee capable of consciously diverting water into a radiator. It was wonderfully simple. It has one way in and two ways out. It has a cuff cast into the inside to coax some of the water out the side rather than have all of it flow straight through. Mr. Schlemmer was a hot-water man and he was looking for ways to compete with the steamfitters. They had an advantage at the turn of the century because steam return pipes are smaller than steam supply pipes. A hot-water man had to work with larger pipes, and the return lines were as large continues on page 68

as the supply lines. And there were no circulators. We don’t see those until Homer Thrush (in the U.S.) and Louis Opländer (in Germany) simultaneously invent them in 1928. Mr. Schlemmer had only gravity.


Oh, and delta-P. Mr. Schlemmer’s tee looks so ordinary from the outside. Of course the water is on the inside, where the magic happens. When the water crashes into that internal cuff some of it is going to flow out the sside of the tee and into the radiator.

I was reading the Bell & Gossett Handbook from 1949. It showed me the Monoflo piping for a 10,000 BTUH convector installed on the first floor of a house. The horizontal supply main was in the basement. The book tells me that I need just one Monoflo tee on the return side of the convector as the flow re-enters the main. The pipe size to and from the tees to the convector will be half-inch. Seems easy, right? But in the next drawing, they show that same convector on the second floor of the house. The supply and return piping to and from the convector just got a lot longer, which means that the water’s going to experience more pressure drop as it flows from the main up to the convector and back to the main. Can you feel it? If you were the water, would you go to the second floor, or would you just stay in the basement and keep sailing along that main? But before you decide, know that the B&G folks insist that you use two Monoflo tees for that convector on the second floor – one on the supply and one on the return. That’s going to make it tougher for the water to stay in the main.

This gave him a way of piping hot-water with one pipe instead of two. By splitting the flow, his fitting let him compete with one-pipe steam, which was cheaper to install than a two-pipe, gravity-hot-water system. Oliver Schlemmer invented onepipe hydronic heating. Later, Bell & Gossett’s Monoflo Tee and Taco’s Venturi Fitting followed, but both owe a debt to the O-S fitting. And they all obey The Law of the Tee (see sidebar). Whatever goes into a tee must come out, and if you plan well, the water will go where you want it to go.

And B&G also has us increasing the size of the pipes going to and from the convector. We now have to use three-quarter inch instead of the half-inch we used when that convector was on the first floor. There’s less pressure drop though the larger pipe, so the water goes upstairs. Think it though and feel it. If you don’t, you’re liable to suspect that that second-floor convector is air-locked when it won’t get hot.


KEEPING HISTORY ALIVE For years, I had an O-S fitting on my desk, and I would look at it and consider all that it meant to hydronic heating. A friend once showed interest in the tee, so I gave it to him. We never really own any of these artifacts. We only take care of them and share them.


My teacher, the late, great Gil Carlson, who thought up much of what we today consider Hydronic Law, used to talk about The Law of the Tee. The first time I heard him mention this was during a talk he was giving to a large group of engineers in New York City. Pens were poised to jot down Gil’s explanation of that oh-so-important law.

“Whatever goes into a tee,” he said, “must come me out.” And then he smiled this maniacal grin he had as everyone wrote it down. There’s a simple beauty to that law and one I’ve considered every time I’ve visited a misbehaving hydronic system. When I start to troubleshoot a system, I look to the tees and ask myself, “If I were water, which way would I go?” And then I try to feel any difference in pressure, the delta-P. And I’ll lean into it, as though I’m in a fast car, going around a curve. I’ll also make a sketch of the piping system, because it’s always easier to troubleshoot in two dimensions than it is in three. I’ll look at the tees and ask that same question again and again, feeling the pressure differential each time as I imagine myself flowing from the pipe into each tee. “What would I do?”

dentical twin brothers Drew (left) and Jonathan Scott have been competing with each other all their lives, but that’s not a bad thing. As co-hosts of such shows as Property Brothers and Brother vs. Brother, the pair poke fun at each other, in a good-natured fashion, while helping homeowners and home improvement experts transform handyman specials into dream homes. Key targets the pair often cite to add value in a home include kitchens and bathrooms, but the mechanicals in the basement and behind the walls matter too. “The mechanicals of a building are often taken for granted, but that usually means the skilled people who put them in did a good job,” said Drew during a recent interview. “While surface features get most of the attention, if a home has plumbing or HVAC issues, it’s probably not going to sell unless they’re corrected. Plus, today’s savvy buyers appreciate energy and water conservation, and updated, well-installed plumbing and HVAC systems are a big part of that.” The ability to spot diamonds in the rough, and to make money by flipping real estate, started early for the twins. At 18, they bought their first project home, fixed it up and netted a nifty $50,000 when they sold it about a year later. Since then, Jonathan became a licensed contractor and Drew a real estate agent, and the pair has continued their collaborative ways in a whole host of endeavours, foremost among them has been the creation of Scott Brothers Entertainment where they focus on creating original content for television and digital platforms.

Building bathrooms and kitchens Potential buyers of a property are more likely to be swayed by a stylish kitchen or bathroom than any other room in the home, and the Scotts like to tap into this by providing their clients with modern, stylish features, as long as they provide good value. “Anything that gives a bathroom a spa-like atmosphere is very appealing,” says Jonathan. “If there’s enough space, put in a separate walk-in shower with a glass door and a rainfall showerhead. For added luxury, install extra nozzles.” If your customer has thoughts of ripping out the tub in the only bathroom in the home so that they can put in an impressive shower, you might want to get them to think twice, says the contractor. “The home should have at least one bathtub, for future resale value.”



When not on camera, Jonathan is an award-winning found behind the lens, directing

Thereâ&#x20AC;&#x2122;s value in the mechanical room A tall order â&#x20AC;&#x153;In season two of Property Brothers, and again this season, we did bathrooms for clients who were just as tall as we are,â&#x20AC;? says Jonathan. â&#x20AC;&#x153;They speciďŹ cally wanted tall ceilings, tall doors, a shower with extra height and, of course, really big mirrors.â&#x20AC;? He created a space with marble and other classic materials that created a spa-like oasis that he says would make his clients want to stay in the shower all day. â&#x20AC;&#x153;I guess Iâ&#x20AC;&#x2122;m responsible for making people wrinkly,â&#x20AC;? he laughs.

LIGHTS, CAMERA HVACACTION! Anything can be made and filmed in the largest purpose-built studio in North America, but managing the air in a constantly changing environment is not without its challenges.


Photos: Pinewood Studios Ltd.; Insight Productions; CBC; Adam Freill

sound studio’s role in life is to be a big, soundless, empty space. It is essentially a large box that must be isolated from the outside world to provide highly creative people with a place to create different worlds and realities, but that’s not to say that the principles of science are suspended. Managing heat and mitigating sound are two of the key challenges when designing mechanical systems for a studio, explains Les Klein, a principal with Quadrangle Architects, the firm that originally designed the Mega Stage at Pinewood Studios, and the surrounding complex on the eastern waterfront in Toronto, when it first launched as Filmport. “Film is incredibly sensitive to sound, so you have to make sure that however you bring air into the space, it comes in at a very low noise volume,”


he says, explaining that to do this, they use extra-large ducts and large low-velocity fans. Large louvers on the north and south ends of the structure allow air into the mechanical space through acoustically lined ductwork. The treated air moves through a series of filters from the mechanical room to a duct header, and from there a motorized damper controls how it is distributed to four acoustically lined ducts. But getting cooled air down to the set is another matter. “There’s a convergence layer of heat that comes up from all the lights and equipment,” says Fletcher, “so the cool air has to break through a layer of heat. By the time it does get down to floor level, it’s sometimes significantly warmed by the heat layer it went through.”

M e c h a n i c a l

Perhaps one of the strangest episodes in Mike Fletcher’s mechanical building experience came the day it began to rain inside the 46,000-square-foot soundstage where he is the facility manager. In 2010, the barrel-vaulted, cement-roofed Mega Stage, easily recognized from the nearby Gardiner Expressway for its 18 massive, fire-engine-red steel buttresses, had been rented out for the second season of CBC’s Battle of the Blades. The first season was shot at Maple Leaf Gardens but the production lost the use of the space when work began to convert The B u s i n e s s

Gardens into a Loblaws grocery store with a Ryerson gym and rink overhead. Challenged with trying to rent ice for 10 weeks during hockey season, the show’s producers settled on the idea of building their own rink at the Mega Stage. An intricate web of plastic tubing was laid out and soon glycol coursed through its lines to chill a 200-foot by 70-foot slab of ice for the show. Bleachers were erected for the 1,730 audience members and the whole set was surrounded by five kilometers of thick 40-foot-high black curtain.

• An i ndoo r r a i n s t o r m • A ligh t ap p r o ach • W h er e t h e act io n is Among the productions that have been shot at the Mega Stage are:

A LIGHT APPROACH While cast and crew comfort is one element, it is also important to keep things cool for the lighting rig. “If it’s an interior scene and they just want even light, we use a ‘space light’ which is 6,000 watts. And if it’s a big set like RoboCop, they could have as many as 100 of these lights,” explains Mike Harwood, the national director of technical support and development for William F. White International, one of the largest film equipment rental firms in the world.

Robocop (2014) Total Recall (2012)

Pacific Rim (2013) The Thing (2011)

But too much heat can have an effect on the equipment. Harwood says a space light typically gives off 260°F. All that heat floating up to the rigging can be considerable. “I’ve been in studios where the I-beams are hot to the touch,” he says. If the lights overheat they start to flicker because the heat load is adding resistance to the line. And a flicker can ruin the shot, Harwood explains. To keep the air moving, large variable speed fans pull hot air out through the louvers at the north and south ends of the building. They also work to pull the heat from the York unit condensers. It’s not very different from a system that might be found in any other space this size, except that it’s located inside. To move the heat generated by the condensers, each unit has a large fan assembly suspended several feet above it that exhausts this heat as well as any special effects fog or smoke as needed.

WHERE THE ACTION IS The challenge with a film studio is that it is not a continuous environment. Air has to get down to where the action is. That’s why the ducts have removable cutouts about the size of a pie plate. Crews attach long polymer bags to the cutouts that allow the air to drop freely from the system and pour out into a specific area – whether it’s a reconstructed living room, a post-apocalyptic waste land or a medieval courtyard.

DID YOU KNOW? Ontario is home to Canada’s largest film and television sector. In 2013, the film and television production industry contributed $1.15 billion to the provincial economy.

For heating and cooling, the sound stage is serviced by four 30-ton York units, housed in pairs in the north and south mechanical mezzanines. These units feed into duct headers at either end that span the width of the building, and each header has four runs that reach half the length of the building. Everything sits suspended from the vaulted ceiling, approximately 60 feet from the ground. With a grid overhead holding

hundreds of lights, crews were readying to shoot the skating show when Fletcher received an unusual request: “Can you turn the heat on?” Typically, productions generate enough heat that they are in need of cooling rather than heating. But in this case, the audience was getting cold and the producers wanted to warm the area over the bleachers. Fletcher expressed concern that this would be dropping warm air on what was essentially an ice box. But he M e c h a n i c a l

fulfilled the request and turned on the heat for the audience. “First, the space started to fill with a heavy fog,” recalls Fletcher, “and then the warm moist air began to condense and basically, it started to rain inside the building. People were looking for shelter under the bleachers.” It was an exceptional circumstance to be sure but the problem of competing layers of cold and warm air in this large a studio is a typical one.

HVAC Choices for

“Zero Energy” Homes S

o what kind of HVAC system do you put in a house that is supposed to, at the end of the year, use no energy? That may sound like an oxymoron, and at the least not a very fair question, but it is worth considering the optimizing of HVAC options for what has been referred to, up until recently, as NetZero energy homes.

Gord Cooke is a professional engineer who has spent 20 years helping builders and HVAC contractors implement innovative technologies into high-performance homes. He has particular expertise in IAQ and air flow management in houses, and can be contacted at

Zero-Energy homes should be seen as an opportunity for our industry. New equipment, better controls, monitoring, expert installation and thorough commissioning will all be required, and thus, professional HVAC contractors, ready to learn and embrace new technology will be an integral part of the success of future new homes. For something a little different, let’s take a look at some of the decisions I have been considering for my modest cottage that is currently under construction, two hours northwest of Toronto.

The sum of all net-zero parts Let’s go through the elements of my cottage by starting with what, in my mind, is the easiest element, ventilation.

Ventilation: I chose an ERV for latent control in a house that will have very low sensible loads. The most efficient models now have ECM fan motor technology. Given that I will be doing a full independently ducted installation – fresh air to bedrooms, exhaust air from bathrooms and kitchen – that technology will help minimize electrical consumption while maintaining proper air quality control.

because of the balance of solar gain for southfacing windows in winter with allowance of proper overhangs to shade the south-facing glass in summer. I used different glazing coatings on different orientations to optimize the heating and cooling equipment, and overall energy use.

B u s i n e s s

I settled on an R75 cathedral roof assembly, R45 walls, R30 under the slab of the slab-on-grade construction and, of course, triple glazed windows and extremely tight construction. With these elements my 2,100 square foot, 1.5 storey home ends up with a total design day heat loss of just under 20,000 BTUH. So I thought I had it aced, until I had the design checked out with the Passive House standard.

I did the math and determined it was less expensive to add a few extra solar panels than it was to increase the insulation levels to Passive House standards and I gave up on that label.

With such a small load, but an intermittent load presented by the potential solar gain, I wanted flexibility as well as efficiency. I looked at a ducted, zoned system with a twostage condenser, but decided on a two-head, variable output system. M e c h a n i c a l

For my cottage, specifying the enclosure elements was a process that can simply be described as deciding on more. Whatever you may think is enough insulation, think again.

They recommended an R100 roof, R75 walls, and an R50 slab, as well as 0.6 air changes per hour at 50 Pascal air tightness. (That’s more than twice as tight as an R-2000 home.)

Cooling: The load will be just 1.25 tons

Many thought I should just do a couple of ductless mini-splits, but I wanted to demonstrate the slim duct air handlers that I think, ultimately, will be more acceptable to Canadians in mainstream homes. So, I will split the house east/west and have a very efficient, flexible system.

Heating: The cooling decision led me to the larger decision for heating. The slab-on-grade construction and fully ducted ERV made in-floor heating a “no-brainer”. So, yes, there are six loops of in-floor heat on the main floor, with R30 insulation underneath and a special thermal break detail in the frost wall. I also wanted to take advantage of the slim duct units by making them a heat pump version. That gave me a lot of capacity for a small load, and I still had to decide on a heat source for the hot water in-floor loops. Taking into account that, for the foreseeable future, the home will be used only occasionally in the winter, I decided to do an all-electric home. The main heat will come from the air source, low temperature heat pump with the two slim duct air handlers. The in-floor will be mainly a floor-warming system that will be a heat sink for a solar hot water panel system. Peak load will come from a back-up electric coil in the water storage tank – call it emergency heat.

Hot water: I have installed a hot water solar panel with a back up coil in the storage tank, however I am very interested to see how the heat pump water heater that we are installing will work. Extensive modelling by NRCan has shown that in very efficient homes – where hot water loads are often larger than space heating loads – heat pump water heaters, over the course of a year, should provide a very good total energy used benefit. Consider that even on a cold, sunny day my south facing windows will provide more heat than I need, so the “cooling” provided by the water heater on that day won’t go to waste. I promise I will follow up in future articles and let you know how that is working out.

What’s in a name? The nomenclature of net-zero may be changing due to an initiative by the Department of Energy in the U.S. In looking at better ways to communicate the value proposition of homes that, on average, only use as much as they are able to produce themselves on site, they are considering the term, Zero Energy homes.

Solar shingles: The final pieces are the solar PV shingles. New to Canada as of this summer, I truly believe this concept will be a game changer for solar acceptance. They are more expensive, in the order of 40 per cent higher total installed cost than the typical solar panels, but they look great. My new neighbourhood is already a-buzz. I was able to cram a system with capacity of around 5.2 kW on my roof. With the optimized roof angle, and almost direct south exposure, the expected production of this system should come within a light flicker or two of making the home a zero energy home – only using as much over the year as the shingles are able to produce. It won’t likely qualify for the net-zero designation that is currently being promoted by NRCan and the Canadian Home Builders Association, because the home falls just short of the required energy modelling criteria. There will be two electric meters, one allowing electricity in when I need it, and one going back to the grid for others to use. It’s uncertain if I will be able to get a contract to sell the power back at a preferred rate, but if not I will still be satisfied with simple net-metering, which I am confident will result in a net-zero annual bill.

DID YOU KNOW? Canada Mortgage and Housing Corporation developed a pilot program in 2004 that led to a net-zero project in Edmonton in 2007.

EFFICIENCY, That Fits to a T L

ow Delta T is a costly problem in many large-scale facilities, and on sprawling university campuses with central chilled water plants, it can often be a major source of inefficiency. This type of temperature concern happens when the supply and return chilled water temperature across an HVAC system is less than what the chiller’s design calls for. Oversized, damaged, fouled or degraded air-handling coils are often the main cause, however poor system balance or improperly installed and controlled air handlers can also contribute to it as well. Especially under partial-loading conditions, low Delta T often results in the need for additional chilling capacity even though cooling load hasn’t increased. This is largely due to the fact that as heat transfer drops, chilling units and pumps have to work

harder in order to maintain a given temperature set point. When return water temperature to the chiller is lower than the unit’s intended design specifications, more water has to be pumped through the system. When this occurs, air handler operating efficiency goes down and utility costs go up. As a result of the costly mechanical problems that low Delta T can cause, there is significant opportunity to take advantage of savings by utilizing products that protect against it. This was evident on two separate structures at the University of New Brunswick (UNB) in Fredericton, where the use of a specialized type of valve helped achieve real-world savings through the optimization of chiller operations.

QUICK RESULTS A HISTORY OF CONSERVATION The University of New Brunswick’s Energy Management division has been investing in energy conservation methods for nearly 30 years. In early 2012, school officials began discussing the possibility of reducing power consumption on campus by improving chiller performance and eliminating low Delta T. After careful consideration, the school contacted Belimo when the decision was made to install a pressure-independent valve that measures and

Operational savings resulting from the optimization of the chiller in the air-handling unit have been estimated to be just over $1,200 per year, which equates to a payback period of just over four years.

manages coil energy by using an embedded flow meter, along with temperature sensors on both waterside supply and return lines. The valve controls flow through each coil (directly) with a control signal, rather than indirectly through a valve position. When the upstream pressure changes, a microprocessor adjusts the valve position through a device-internal cascaded control loop. This technology differs from conventional pressure-dependent control valves in which flow variations are corrected only after they’ve been detected by the coil control loop. In addition, by measuring flow and Delta T simultaneously, waterside-cooling continued on page 98

loads can be calculated and a coil characteristic of load versus water flow can be established over time, which can be used for a number of different diagnostic purposes. With an integrated BTU meter that provides coil performance data, the valve provided energy officials at the university with the ability to verify system performance during commissioning. This information will act as a baseline standard for system performance over time. The valve also gives system operators precise control over air handling units by providing a linear heat transfer regardless of system temperature variations. In an effort to minimize costs and see first-hand how it would

perform in real-world conditions, UNB coordinators decided to install a single valve as an experimental project on an air handling unit (AHU-1) in the university’s 22,667 sq. ft. Information Technology Center (ITC) building. Host to the university’s Computer Science department, the primary purpose of de AHU-1 in the ITC building is to provide a comfortable learning environment in offices and classrooms for faculty and staff. The building is home to one of several computer server rooms tthroughout the campus, however, that particular space is cooled by a th standalone system that’s not controlled st by AHU-1. b Because the installation of the valve was experimental, the only requirements of the project were to install it in a cost-effective manner, improve chiller performance, and achieve measurable energy savings.

MEASURING TO GUIDE CHANGE The ITC building’s existing air-handling system featured a three-way bypass valve with a large chilled water loop that resulted in high pump rates and excessive energy usage. As a result, it was an ideal target for an energy efficiency improvement project. While the primary purpose of bypass valves is to avoid operating constant speed pumps against closed control valves, they often lead to constant primary and secondary mass flow rates, which in turn lead to Delta T degradation under partial-loading conditions. Based on AHU-1’s air coil (and applicable pump) design flow of 126 gpm, an appropriately sized valve was selected as a

replacement of the bypass valve. And because the Energy Valve has the ability to record, regulate, balance and save all measurement data, it allowed personnel within UNB’s Energy Management division to accurately view its performance in real-time. Engineers could also monitor the coil’s performance and optimize its operation by maintaining the Delta T as well. In addition to the standard analogue signal and feedback wiring, the valve communicates data to the building management system via BACnet MS/TP or BACnet IP. A builtin web server also collects up to 13 months of data, which can be used for further system analysis.

Moving Forward at UNB As a result of the savings achieved at the ITC building, coordinators in the university’s Energy Management division decided to move forward with the installation of a second valve on a separate 92,680 sq. ft. campus building, Bailey Hall. “The primary goal of energy management at UNB is to control and reduce energy consumption on campus, and to enhance the learning environment through improved comfort by operating buildings and equipment in the most efficient manner possible,” explains Tim Cross, the school’s Energy Coordinator. “We’ve been very pleased that such an emergent technology has helped us achieve that goal.”

A sustainable approach to recovering energy from compressors

Reclaiming excess T

emperature control in compressor rooms is critical. To keep the temperature below the preset value required to ensure proper equipment performance – a setting that is very often 40°C – excess heat must be removed. This is generally done by circulating fresh or cooled air, but some building system designers are now considering the use of excess heat from the compressors to heat the adjoining areas, thus providing a free source of heating. Air compressors are a fundamental part of many industrial facilities. These compressors can produce a large amount of

he heat, which is an ideal target for heat recovery. In general, about 72 per cent of heat generated from airair-cooled compressors can be recovered. Although around two per cent of the heat will be radiated in the compressor room, this radiated heat can be removed by circulating fresh air through an exhaust fan and a fresh air intake. On the other hand, water-cooled compressors radiate about 85 per cent of heat to the cooling water, which may then be utilized to pre-heat an air stream, or to temper the water through a heat exchanger. This tempered water can be used for washing purposes.


provide heating and ventilation to the space. Heat from the compressors could be used as supplemental heating to raise this room’s temperature and reduce the air handling unit’s heating requirements. As such, the costs for gas or hydro consumption can be reduced, simply by repurposing excess heat from the compressors.

Here is a sample system where three air-cooled compressors are being used, and were the excess heat could be used to warm a large water filtration area. This area has its own gas-fired air handling unit on the roof that is dedicated to

In the system illustrated, the ventilation control panel monitors heating demands in the compressor room and in the open-filter area. When heating is needed, the controller will modulate the exhaust damper, recirculation dampers and the reclaim dampers simultaneously to maintain temperature in the compressor room. Once the compressor’s room temperature has been satisfied, the majority of the excess warm air will then be directed into the filter room by modulating the exhaust, recirculation and reclaim dampers. When both rooms have been satisfied, any excess warm air will be discharged outside through the exhaust dampers. The ventilation control panel will be able to manage the temperature, humidity and pressurization in the filter area. It will also maintain a slight positive pressure by modulating the roof mounted exhaust fan variable frequency drive.

DON’T OVERLOOK THE WATER When moving air in a system that’s reclaiming energy, it can be beneficial to take humidity into consideration. In the example above, since the area is an open-water filter bed, humidity needed to be maintained to prevent mould and 100

mildew from growing on the floor, walls and ceiling. We have included a controller that will monitor the space humidity and, in the event that the outdoor humidity level is greater (field adjustable) than the humidity parameter that’s been preset for the filter area, the compressor air will be exhausted.

Vandals at bay The state of a washroom has a huge impact on the perception and behaviour of a user. When facilities are well designed, cleaned and maintained, the odds of vandalism occurring are significantly reduced.


t is a fact of life, public washrooms are destined to be sprayed, marked up, smashed, bashed or otherwise destroyed in some way, shape or form.

It is unfortunate, but when you consider that there are tens of thousands of schools, malls, recreation centres and various other public washroom spaces across Canada, with millions of users every day, the reality is that there is always going to be those among us more interested in vandalising the washroom than using it for its intended use. The problem is so prevalent that police associations across Canada estimate that graffiti costs taxpayers over $1.4 billion annually. There is even a term for bathroom graffiti: Latrinalia. Intelligent washroom design and product installation can help limit most forms of vandalism. Unfortunately nothing is 100 per cent foolproof, and there will always be those who choose to destroy property, and some will go to considerable lengths to cause damage. The first element to reducing vandalism is to identify the type of facility and typical user group most frequently present, and selecting products and basing designs on the expected users. It can also help to break the restroom down into sections – water closet, urinal, hand washing and hand drying – to address specific concerns in each task area.

WATER CLOSETS AND URINALS Sensor-operated flush products should always be a consideration for public washrooms because this eliminates the want to “kick-flush” or otherwise leave a fixture unflushed. Sensors may create another potential point of vandalism, but the improved level of hygiene generally helps to promote a cleaner space, and a cleaner space is less likely to be vandalized. Sensor-operated flushing products can be both exposed in front of the wall or concealed behind the wall. Concealed is an ideal choice, especially when protected by a stainless steel or metal wall plate with vandalresistant screws for maintenance-only access. Washroom partitions are always a target. Floor-to-ceiling options can help to reduce the instances of doors being ripped off hinges.

BY DEFINITION Latrinalia is a type of deliberately inscribed marking made on latrines – bathrooms or lavatory walls. It can take the form of art, drawings or words, and may include poetry or personal reflections. While this can sometimes make for interesting reading, it is a huge issue for property managers and building maintenance personnel and carries astronomical costs to remove.

Materials of construction are important to consider as well, as some materials are more stain, scratch and impact resistant than others. Sensor-operated flushing devices can be programmed to have a sentinel flush which goes off automatically at a pre-determined interval. They can also be programmed to eliminate multiple flushes, which can occur when the override button is pressed repeatedly. If manual flushing devices are being used, it is important to use ones that are considered “non-hold open,” meaning that even if a user is deliberately holding the handle in an open position, the device only flushes once. This feature can eliminate flooding and preempt potential vandals.

HAND WASHING AREAS Eliminating touch points is the first step to eliminating vandalism, so sensor-operated faucets are a good option to consider. Standard infrared sensor faucets can be prone to having the sensors marked or scratched if they are being used in vandal-prone areas, so it is important to select a faucet that has a concealed or hidden sensor. Out of sight; out of mind. Capacitance hands-free faucet technology may also be an option. These do not have a sensor window that can be targeted. Capacitance products turn on as a user draws their hands close to the faucet body, and is a potential alternative for high abuse facilities. The sink or hole type is also a factor. Single-hole faucets can be grabbed and spun around much more easily than a 4” low-profile centreset. Some manufacturers offer faucets with vandal-resistant pins on the base to try and eliminate spinning or turning. Faucet outlets or aerators should always be vandal resistant no matter what flow of water they are delivering. A vandal-resistant outlet can only be adjusted with a special key held by the installer or maintenance person.

continued from page 102

Standard outlets like the ones found on residential faucets can easily be removed by hand. Many sensor-operated faucets require components to be mounted below the deck (i.e. solenoids, mixing valves or soap reservoirs). All of these components can be targets for vandals, which means that sink and counter selection are critical to reducing these opportunities. Wash fountains with a stainless steel or other solid surface shroud are a good option. When wall-hung basins are being used, as is the case in many institutional applications, consideration needs to be given to some type of vandal-proof box that can be recessed in the wall below the sink. The challenge in design is to make the components as invisible as possible in order to avoid mischief, while still allowing for easy maintenance access.


STYLE VS FUNCTION In recent years, commercial plumbing manufacturers have combined their traditional heavy duty products with more design-friendly options. As such, public spaces can look good and still provide a high level of hygiene and durability. Depending on the typical user and expected traffic, comfort options like dual-flush toilets, temperature mixing faucets and foaming soap can all be implemented without sacrificing vandal resistance.


HAND-DRYING STATIONS The most effective way to prevent excess mess and vandalism is to provide a heavy duty, wall-mounted, sensor-operated hand dryer. Hand dryers eliminate excess paper waste and reduce the chances of flooding from a vandal clogging or plugging a sink or fixture with paper towels. A new trend emerging in this area are combined fixtures that allow for water, soap and air drying at one location over the sink. Several manufacturers have launched products like this, and they are an excellent option for high traffic, vandal-prone areas.

Thermostatic mixing,

AND MORE Perhaps the most common three-port valve is the thermostatic mixing valve. This valve has a C port, an H port and a third port, sometimes labelled M. So the valve mixes cold water with hot water to provide a mixed temperature. Typically these thermostatic valves are piped at or near a domestic water heater or a DHW storage tank. This allows the tank to be operated at higher temperature than the water supplied to the building. More energy can be stored in the water in the tank at elevated temperatures, but it is necessary to protect the users from DHW temperatures that could burn or scald them. Depending on the application, 110 to 120°F is a common temperature for DHW delivery. In addition to energy storage, another reason for storing DHW above 140°F is to lessen the potential for bacterial growth. The thermostatic valve can also be used to mix temperatures in a radiant heating system. High temperature fluid from a boiler or heat source is blended with the cool returning flow to achieve the required mixed temperature.

On the right


Another common application for a thermostatic three-port valve is boilerr return temperature protection. The valve ensures sures the temperature at the return port doesn’t drop rop below the required temperature. This ensures es the boiler does not sweat, or condense, for extended periods.

Well, when piping hydronic and solar systems, you occasionally need to divert the flow of fluid in different directions, or to temper water temperatures, so valves were happen. We commonly call developed to allow this to ha these three-way valves, but I prefer to call them three-port valves, as the flow doesn’t ne necessarily flow three ways, or directions.

Inside a thermostatic mix valve is a fairly straightforward construction. ction. The body has multiple ports that are open pen or closed by a floating spool or cartridge. dge.

while they can provide a And whil temp temperature-blending function, ofte often the valve diverts flow to one dire direction or the other.

The spool moves up and down by force applied by the thermal “pill” inside. The thermall pill is filled with a heat sensitive fluid or wax.

Bypass and diverting EXAMPLE 1


Bypass and diverting EXAMPLE LE 2

Creating a diversion


A three-port valve can be built as a bypass or diverting ing valve. One example of this is a three-port ball valve. In the valve pictured, the bypass style allows flow to go straight across the valve, or bypass, to the third port. A diverting valve has one flow into the valve, and two flows out. The bypass valve has wide-open flow across the valve. It basically performs as a full port ball valve. In the bypass mode, flow is reduced as the side of the ball is machined with a smaller dimension passage.

A three-port valve can be equipped with a motorized actuator. A threeport zone valve will typically have connection ports labelled A, B and AB, and flow can enter the valve at the AB port and go one of two directions, either to A port or B port. Check with the manufacturer’s specifications on application, however, since a valve can often be arranged so that a blended temperature fluid can be generated out of the AB port, with a pair of flows entering through the A and B ports. The graphic shows a typical flapper or paddle-style zone valve in a three-port configuration. Manually operated three-port valves can also be used on radiant mixing applications. This type of valve will not provide an accurate mixed temperature, however, as the blended temperature cannot automatically adjust to temperature changes at the A or B port. Most manual three-port mixing valves have provisions to mount an actuator on them for automatic, variable temperature mixing control.

The diverting valve has the same flow coefficient in either direction.

the more common three-port valve designs. Manufacturers can design and engineer three-port valves to match exact system requirements. In addition, actuators can be added to some valves to allow control via input from a controller that modulates the position of the valve. This can allow for precise temperature control. The installer, designer and supplier need to determine what the application requires. Considerations can include flow rates, pressure shut off, control accuracy, code compliance, desire for automatic or manual operation, end switch requirements, low-lead compliance, type of connection, and more. Contact your supplier, rep, or manufacturer to assist you in selecting the appropriate valve for your application.

WARNING A word of caution when using a thermostatic mix valve on heating applications: Pay attention to the Cv number. Select a valve that can flow the gpm you need without excessive pressure drop. Most manufacturers offer high flow versions of their mixing valves.

There is no “one type fits all” valve on the shelves. But the good news is that you have lots of options to create a “custom fit” application.

MATCH THE USE Thermostatic mixing valves often carry an ASSE listing for various applications. Make sure the valve you choose and install is listed for your application. For up-to-date information on ASSE listings, visit and consult with the valve supplier or manufacturer to guide you through the ASSE maze.

PHOTOS HRAI brings its brand to Montreal

The Heating, Refrigeration and Air Conditioning Institute





Managing your brand and your message is important in today’s world of, and, so it was fitting that HRAI kicked off its 2014 conference, held in August in Montreal, with one of the nation’s top branding and creativity experts, Ron Tite. “It used to be that you could tell two people if you received bad service. Now you can reach 2 million,” said Tite, an award-winning advertising writer who has worked with such brands as Kraft and Microsoft. “There’s been a massive change in the world in which we live.” He suggested that a company that adds value to their customer, through making their lives easier or saving them time, will enhance their brand. “Great brands add value, and so do great people.” The conference, which was themed “Building the industry brand” saw more than 220 industry professionals head to Montreal to attend business sessions, discuss industry issues and attend the annual general meeting.


Those in the refrigeration and air conditioning sector were interested in a panel discussion about refrigerants, where Rob Flipse (Gordon Latham), Dennis Kozina (Copeland), Jim Flowers (Linde Canada), Tom Boutette (B&B Trade Distribution Centre) and Ron Vogl (Honeywell) talked about changes to regulations, the emergence of alternatives to HCFC and HFC refrigerants, and the potential delisting of a number of high GWP refrigerants by the EPA in the U.S. in the next year-and-a-half, and the impact that could have in Canada. A special treat during the conference for Montreal Canadiens fans was a visit by Jacques Demers, who discussed what it takes to build a winning team. “The only way to reach the top is hard work,” said the former coach. “And when you reach the top, you need to remember there’s always someone else 1.

Garage IAQ and


arage ventilation has come more into focus since Health Canada found that benzene, a fuel additive, is three-times stronger in homes with attached garages versus those without. Benzene is a recognized carcinogen that can be produced from car emissions, as well as from household products such as paint supplies and adhesives. Health Canada reports that more than half of all single-family homes in Canada have an attached garage, and higher concentrations of indoor air pollutants could potentially result from:


Center for Disease Control claims that unintentional CO exposure accounts for an estimated 15,000 emergency department visits and 500 unintentional deaths in the United States each year. Government health agencies warn against idling vehicles in the garage as even low concentrations of CO can cause fatigue, headaches and impaired motor skills. Very high levels of exposure can result in coma, convulsions or death. Last year, Yukon became the first territory in Canada to require a carbon monoxide detector in every home with an indoor gas appliance or attached garage. The Asthma Society of Canada identifies garages as polluted spaces and offers tips such as weather-stripping the interior door leading from the garage to the house, using a ventilation fan to exhaust fumes, and avoiding use of a remote starter when the car is in the garage.


LOOKING SOUTH Prompted by a lack of field measurements on the subject, and indications from prior studies that air flows from garages could comprise up to 45 per cent of the total air transferred to living spaces, ASHRAE is currently conducting an 18-month research project on the subject.

For the past two years, techniques to reduce the transfer of garage pollutants into the home have been under evaluation in the National Research Council of Canada’s IAQ test house in Ottawa. Researchers at the site have been monitoring leakage rates and air movement, while comparing the energy use of different ventilation and air control methods. The effectiveness of ventilation fans with sensing technology, improved air sealing between the garage and living space, and control of the air pressure are all under study. The

The scope is similar to that of the Canadian NRC study with air flow measurements and evaluations of various remediation methods. The ASHRAE research is expected to wrap up in May 2015. Results and recommendations will likely be published in July 2015.

results of the research are expected to be published shortly. This is not the first attempt by Canadian government agencies to understand the degree to which attached garages compromise the indoor air quality of a home. In 2004, a series of tests were completed on 42 homes in three cities in Canada. Documents published by the Canada Housing and Mortgage Corporation summarize the findings as follows: • Attached garage-to-house leakage accounted for approximately 10 to 13 per cent of total house leakage. • In cases of garage-to-house transfer, carbon monoxide concentrations were within acceptable exposure limits of Health Canada recommendations.

• Garage-based emissions could cause significant indoor air quality problems in the home if more than 25 per cent of house leakage occurred through the garage. Three remediation strategies were evaluated as part of the study: air sealing, use of a transfer grille and installation of an exhaust fan. All proved effective at lowering concentrations of pollutants in both the house and garage. Air sealing was determined to be the best first step to combat the transfer of garage pollutants to indoor air. In addition to air sealing, use of a garage exhaust fan may also be needed to achieve acceptable IAQ levels in the home, the study indicated.

CODES & STANDARDS ASHRAE Standard 62-89 included a ventilation requirement for residential garages of 100 cfm per automobile. That requirement was assumed to have been met by air leakage. Since then, studies have concluded that there are times when air leakage is inadequate to control garage-sourced pollutants. A 2007 addendum to ASHRAE 62.2 contained specific requirements for separating the garage from the living space. The standard states that the design must prevent migration of contaminants to the adjoining occupiable space. Doors between garages and occupiable spaces should be gasketed or made airtight with weather-stripping. The addendum also addresses HVAC systems in garages, including air handlers and return ducts, as having total air leakage of no more than six per cent of total fan flow. Ontario building codes require exhaust fume barriers and self-closing devices on doors between an attached or built-in garage and the dwelling unit. Out west, in B.C., building codes warn that winter season stack action can generate continuous pressure between the garage and the dwelling unit, capable of moving potentially contaminated air into the home. And Saskatchewan codes state that the wall between an attached garage and a house does not need to be a fire separation, but it must provide an effective barrier to gas and exhaust fumes. Additionally,

connecting doors must be tight-fitted, weather-stripped, and have a self-closing device. In the U.S., the International Residential Code (IRC) and the International Energy Conservation Code (IECC) both call for air sealing between the home and the garage. Exhaust fans are required for shared garage spaces. The IRC stipulates self-closing devices on doors separating the dwelling unit from an attached garage, air sealing between the garage and conditioned space, and forbids ducts that service the indoors from also opening into the garage. Energy Star Certified Homes, version 3, revision 7, mandates that ventilation air comes direct from the outdoors, not from adjacent dwelling units, garages, crawlspaces or attics. Additionally, doors adjacent to an unconditioned space (attics, garages, basements) must be made substantially air-tight with weather-stripping or an equivalent gasket. In homes with exhaust-only ventilation, builders that seek the EPA’s Indoor airPLUS designation must install a minimum capacity 70 CFM exhaust fan in the garage that vents directly to the outdoors, or verify that the garage-to-house air barrier can maintain a nominal pressure difference. The EPA recommends use of an Energy Star qualified exhaust fan in garage spaces that are used for work or recreational activities. LEED awards a point for detached or no garage, and for installing a garage exhaust fan rated for continuous operation.

s school commences each fall, I like to ask apprentices about the kind of work they do in the field, as there are so many different aspects of the plumbing and heating trades. At SAIT, it’s usually related to new construction, but from time to time – especially with fourth year plumbing students – we get to talk about service work. And service calls for plumbing often

involve some form of leak, many of which take place in the bathroom. There’s nothing worse than a leaky bathroom, especially when the source of the leak is not obvious. Being in the service industry for over 30 years, I’ve definitely come across many shower leaks. Locating them can be expensive and time consuming, and homeowners don’t typically appreciate it when their bathrooms end up looking like a war zone, with broken holes scattered thought the drywall caused by a plumber in search of an elusive drip. Of course, not finding them can attribute to a serious issue that concerns homeowners across Canada, mould.



Potential health concerns from indoor mould include eye, nose and throat irritation, coughing and phlegm build-up, wheezing and shortness of breath, allergic reactions and symptoms of asthma.

What are the most common culprits when it comes to leaks in a bathroom? With the exception of toilet wax or rubber seal leaking on a toilet, all things point to the shower. Shower-related leaks include hairline cracked shower tile leaks, glass shower doors leaking at their base or door, and finally, the nastiest of the leaks, the shower drain. Shower drain leaks are the worst because they typically leave the plumber with no choice but to rip them out.

CONSULTING CODES In public showers, the National Plumbing Code (NPC) dictates that we must have no more than six showerheads to every one drain, and the showerheads must be 750 mm apart from each other. It also dictates that the drain(s) must be installed under the showerhead(s) with the floor sloping towards it for hygienic reasons. Public shower drains are sized according to the amount of showerheads in NPC’s Table


M e c h a n i c a l

B u s i n e s s

1 0 . 1 4

In residential showers, the previously stated rules are not required as they are private showers, so distances between showerheads become irrelevant. Wherever the drain goes, the flooring or tile installer must slope the floor towards the installed and graded drain. By code, all private showers have to have a minimum 1-1/2” drain; however most plumbers put in 2” drains since they are better suited to drain away the body hair that collects in them. continued on page 120

INSTALL IT RIGHT THE FIRST TIME The most common of all shower drains is the membrane drain. This drain must be installed correctly if you want the consumer to get many years of leak-free service out of their shower. How do we best go about this? The answer is simple. By leaving no chance of water pooling or pocketing under the drain, because this is what causes the leaks.

Here are the steps to ensure a leak-free shower installation: 1. Cut the centre hole for the shower drain in the floor and place the plastic shower drain in the hole to recognize the depth distance between the shower base floor and the top of the drain, where the membrane is inserted. 2. A lower layer of gypsum concrete, or dry pack concrete, must be installed first on the shower base floor. This is necessary so that the plumber can fill up the depth distance from the floor to the plastic drain. This is vital in order to

preventing possible future pooling of wastewater under the plastic drain. 3. The membrane must be big enough to be laid on a 36-inch shower base or floor and be able to be tacked up six to 12 inches up the walls. 4. Form a second layer of gypsum concrete on top of the membrane and grade this towards the centre drain. The shower is now ready for tiling.

SHOWER SELECTION I have been asked over the years, what is the best type of shower to install: a tile shower or an acrylic shower? Whether they’re one-, two- or three-piece showers, acrylic are a great choice since they are usually leak-free. However, I will always say a tile shower is better simply because I prefer the look, as long as they’re installed correctly.

WATER FOLLOWS THE EASIEST PATH There is a famous saying that your car never acts up in front of the mechanic; well, your plumbing never leaks while the plumber is there. This is truer than you know. Fellow SAIT instructor Blair Howes recently recounted a story to me about the hardest shower leak he ever came across. This leak took four days to discover. On Day 1, he made a service call to a customer who had complained that his shower was leaking. Blair went through the typical routine of turning on the shower and spraying all the walls to see if he could recreate the leak. There were obvious water stains on the drywall ceiling beneath the shower, so this is where he placed himself to locate the leak. Nothing happened. He then ran the tub tap only, to see if the tub tap was the source of the leak. Nothing happened. Next, Blair taped a wall of plastic across the shower to imitate a human body to see which tile or walls the shower sprayed. Nothing happened. Over the process of four days he hit the customer with questions


M e c h a n i c a l

B u s i n e s s

1 0 . 1 4

such as, “When do you take a shower? How many people use the shower? How many times a day do they use it?” Still, nothing stood out as abnormal. Finally as a last resort, he started cutting holes in the wall and ceiling below to see if he could trace the leak. Water stains were found all around and under the shower and tub, LÕ̘œÌ…ˆ˜}i>Ži`܅ˆi…iÜ>Ã̅iÀi]iÛi˜܅i˜…iwi`̅iÌÕL right to the top and drained it. Then, nonchalantly as they were talking, both Blair and the customer realized it had rained four days before, so he climbed up on the roof and commenced showering the tiled roof with a garden hose. Sure enough, water started leaking through the roof, down to the attic rafters, then followed a perfect path right to the shower wall, dripped down the wall and showed up directly under the shower. In other words, if all else fails, check the weather history. You never know what path a water leak can take.

What’s that


Diagnosing a boiler system by ear


ow I’m not advocating that your ears should be your default method of system diagnosis, but sometimes they can be a major troubleshooting tool on a jobsite. When there’s a very obvious sound, it can help to have some idea of potential causes for the sound, and what trouble it might indicate, before you start taking things apart. Here are some general ideas about some of the sounds you might hear from heating equipment, and how the noise may relate to specific problems.


M e c h a n i c a l

No joke, but I’ve seen ÃÌi̅œÃVœ«iÃÕÃi`ˆ˜̅iwi`° They are used to pinpoint a ÜÕÀViœv˜œˆÃiˆ˜>LœˆiÀ ÃÞÃÌi“]ÕÃÕ>Þ܈̅ˆ˜̅i LœˆiÀˆÌÃiv°


As a general statement, I’m going to say that these noises typically aren’t the fault of the heating system. With no air in the heating pipes, there really shouldn’t be any sloshing or watery noise. Most of these issues relate to the plumbing system. However, in a few cases, water could be moving so quickly through the pipes that it could be actually causing what is commonly referred to as “velocity noise.” If you are hearing this noise, and it’s truly in the heating system, then a fix needs to be implemented since the heating pipes are being worn out. Regardless of how clean the system fluid is, a water velocity of eight feet per second, or more, is going to cause wear on the inside the pipes, which can lead to pinhole leaks. The primary causes of velocity noise are either an oversized pump, or the lack of a differential pressure bypass. In this latter case, only a few zones may be operating, and all the flow from a main system pump is being forced through those few zones. In both cases, I would call it a system design problem, or the installation does not match a proper design.



B u s i n e s s

Generally this means kettling – the water inside the boiler is flashing to steam due to the boiler’s inability to pass the heat into the water, and to have the water carry the heat away before it superheats. There are a few causes of this behaviour. The simplest explanation is a lack of flow, or insufficient flow. The water is being overheated inside the boiler, and the water isn’t moving, or isn’t moving fast enough, for the amount of heat being generated by the boiler’s burner. However, insufficient flow has several causes as well. If you have flow meters on the system, or if the boiler can display a measured flow rate, this possibility

1 0 . 1 4

is easy to check. If not, it may be possible to check for flow by simply feeling the inlet and outlet pipes to the boiler (do this carefully, however, as the outlet could be hot!). A pump indicator can also provide an indication of whether the pump is operating or not, but beware – a broken impeller inside the pump will make the pump indicator believe that the pump is moving water, but it might not be. Again, simply checking the temperature of the pipes on either side of the pump could give you clues, but in this case, the pump itself could be generating heat, and the heat might be migrating down the outlet pipes, so check as far down the run as possible. Heat should be even along the entire length of the pipe. continued on page 124

continued from page 122 continued from page 32

Possible pump problems that can cause insufficient flow include:

• Deadheading (backwards install, closed isolation valves); • Broken impeller; • Failed pump; • Debris jamming impeller or other blockages; and • An undersized pump. A second possibility, which is more serious and more rare, but is one I’ve seen on multiple occasions, is that the interior of the heat exchanger has blockages or has been coated with a foreign substance (such as flux), and is no longer able to transfer heat to the water efficiently.

If this is the case, the specified pump rate for the boiler will no longer move the water quickly enough for the heat to be carried off before the water flashes to steam. To solve this more serious issue, flushing the boiler with water or an approved cleaner may solve, or at least minimize, the problem. The issue with blockages can be more serious, however. Some boilers on the market today have multiple-path heat exchangers, meaning that it’s very difficult to flush blockages through all the pathways, since your flushing will take the easiest path (that is, the ones that aren’t blocked). Backflushing can sometimes help in this situation, but contact your boiler manufacturer or representative for the best approach.

WHINING OR SCREECHING These noises usually indicate failed bearings in pumps, or dry pumps. Both are relatively rare, but will annoy the homeowner like nothing else. In most cases you can easily locate and replace the offending pump. Want to look like a superstar? If the homeowner is up to it, ask them to bring the phone into the boiler room where you might be able to diagnose the problem (and get the correct pump size) before you even step foot in the house.

LOUD, INTERMITTENT GROWLING OR HUMMING I’m not sure how else to describe this, but if you’ve heard some of the self-contained water make-up units, also known as system feeders, you’ll recognize the pump noise I’m talking about. The units use small, but typically-noisy pumps (especially some of the older designs of feeder). I have one in my house and even after years of owning it my wife still asks me about the noise every fall, when the heating system starts up again. It’s typically intermittent because the air separators gradually collect enough air to vent, causing the system feeder to run. If it really bothers the homeowner, you can replace the pump with a more recent model, which are typically quieter.

HISSING NOISES These noises are a lot less common, but often come from the air vents. Unfortunately, this is usually the symptom of a bigger problem, such as a leak in the system, where air-laden makeup water is continually being introduced to the system, and the air separators are working overtime to vent it. Alternately, the air vents could have failed and are now pulling air INTO the system, increasing the corrosion rate of all components.

Field automation belongs in your



aper work orders could be costing your business a lot of money. How much? I know a company that switched from paper to electronic workflow for its field service force that estimated that invoicing delays and omissions due to lost or incomplete paperwork had accounted for a loss of up to 10 per cent of its revenue. Yes, 10 per cent! That takes into account money that can’t be billed until the work order is found (how often have you crawled around in a truck, poking under seats to find missing work orders), and signed work orders that don’t reflect all parts and labour. And think about the other paper-based time wasters that add to costs: waiting at the parts counter for a requisition, for example, or going into a site blind because the equipment’s service history isn’t available off-hours. Field service automation software on tablets can eliminate those problems. The time is ripe. A few years ago, when we were automating people who had never used a computer before, they resisted and said, “I like my paper; I like the way I do things now.” Today, most service technicians have experience with a personal mobile device. Many are asking, “Why can’t I use this in my job?” Putting together a field automation system comes with costs, but the payback can be huge. Better customer service and asset management alone provide quick ROI, and the streamlined workflow will boost overall business productivity. Like any well-chosen tool, field automation will let technicians do their jobs more effectively, without getting in their way.

CONSUMER PRODUCTS ARE FOR CONSUMERS Consumer requirements are very different to those of a worker in the field, so choosing an automation solution isn’t just a matter of handing out iPads. Consumer-grade apps won’t do the job. Field service workers need their entire workflow at their fingertips, with secure ties to back office functions like service history, inventory and accounting. And while many consumers are willing to work with a

APP VS SOFTWARE When we talk about apps and software, it’s important to remember that an app is software, but software isn’t necessarily an app. Today we call programs that run on mobile devices such as smartphones “apps”. Think of an app as a snack – a standalone program that does one thing, hopefully well. It doesn’t have to talk to external data sources, but it usually does. A software package, on the other hand, is a full meal. It usually runs on a PC, Mac, or tablet, and can be as small as an app, or an end-to-end system that handles all aspects of field service automation workflow, from dispatch and work order processing to inventory management and invoicing. smartphone that lasts less than a day, because it’s new and it’s cool, in the field, workers need all-day battery life. Consider usability as well. Can the device and its software be used when the worker is wearing gloves? Is the screen visible in all lighting conditions? How will technicians enter text on a tablet with no keyboard? And is the device rugged enough to survive harsh working environments in the field? Can it handle the dust and grime, rain and snow, and the inevitable bumps and accidental drops?

Getting a handle on


CONDITIONS MATTER A funny thing about leaks is that they can be elusive fellows. While larger leaks can be easy to spot with the right tools, some leaks will only exist under specific operational conditions. It could be beneficial to re-test systems under more than one operating condition as gas can escape at different times and at different rates.

hether commercial, industrial or residential in nature, every system that contains refrigerant has leaks. The ones that are easy to spot are the pound per second evacuations. On the other end of the scale are what most technicians aim to install – those systems that lose an ounce of refrigerant every million years or so – but if a pressurized system contains refrigerant, you can bet it has a leak of some size. Joint fittings, seams and welds are typical locations for leaks. Given enough time, vibration and environmental stresses, even the small undetectable leaks can turn into larger, detectable ones that will require repair. Most leaks will fall into one of six classifications, ranging from being detectible when the system is off, to being detectible during certain operating conditions.

Class 1. Standing Leaks (SL) are leaks that can be detected while the unit is at rest (off) and fully equalized. This includes freezer evaporative coils warmed up by defrost. SL leaks, fortunately, are the most common of all.

Class 2. Pressure Dependent Leaks (PDL) are leaks that can only be detected as the pressure is built. Nitrogen is used to pressurize low sides to 150 psi and high sides to 450 psi. Never use CO2 or Oxygen to try to locate these leaks. Helium or dry air are acceptable. PDL testing should be conducted if no leaks are discovered by the SL test. Class 3. Temperature Dependent Leaks (TDL) are leaks associated with the heat of expansion. TDL usually occurs from high ambient air, condenser blockage or during defrost.

Class 4. Vibration Dependent Leaks (VDL) occur only during unit operation. The mechanical strain of motion, VSXEXMSRVIJVMKIVERX¾S[ or valve actuation are all associated with VDL.

Class 6. Cumulative MicroLeaks (CML) are, as the name suggests, an amalgam of all the individual leaks that are too small to detect with standard tools. The total loss over many years of operation slightly reduces the initial gas charge. -RTVEGXMGIXLIQSVI½XXMRKW [IPHWWIEQWSVKEWOIX¾ERKIW a system has, the greater the amount of CML.

SENSING THE PROBLEM The basic leak detection toolkit starts with our senses; listening for large leaks, sniffing for certain gases, feeling for oil residue and looking for leaks by watching bubbles or foam actively brew at the point of leakage. When leaks cannot be detected or located with our basic senses and tools, electronic instruments such as halogen instruments or helium mass spectrometer may be called into service.

A level approach to the

Jobsite A

s jobsite layouts continue to grow in complexity, traditional tactics for completing the job are becoming obsolete. Gone are the days when levelling projects, for example, were strictly a two-man job. Nowadays, a growing number of professionals are turning to laser levels to get a project done. The result: more precise layout work in a shorter period of time. Known for their extreme accuracy and time-saving capabilities, laser levels provide a hands-free levelling solution for a wide variety of projects. By simply pressing a button, professionals can project a laser beam onto a wall, floor, ceiling or other application site, thus eliminating the need for the often inaccurate handheld bubble level. In addition, many laser levels now offer an internal pendulum that provides the capacity to self-level prior to use. This pendulum not only reduces the


chances of human error, but also allows for a more accurate layout from the beginning of a project. “We all know that precision levelling, and getting the right measurements, is critical to completing a job successfully,” says Olivier Vareille, measuring tools group product manager at Bosch Power Tools. “Laser levels provide the best level and alignment solution. They allow you to work with increased efficiency by eliminating the need to mark your level before completing the job. Instead you have a benchmark that’s always there and you can go straight to the doing.” According to Vareille, the use of laser levels is a trend that doesn’t show any signs of abating. “They’re more popular than ever,” he says. “Once you use a laser level, you won’t return to the old ways, even for simple things. They’ll save you time and ultimately money.”

The future of laser levels


Today’s professionals are working faster and more accurately than ever to measure and lay out designs. As laser level technology continues to evolve and improve, the benefits will result in increased accuracy along with a more compact and versatile device. For example, we’ve already begun to see the inception of Bluetooth wireless technology incorporated into laser measures to transmit jobsite data directly onto images uploaded in a smart device, thus eliminating the need for pen and paper. On the levelling side, “we are starting to see the advent of multi-function lasers that pack all the applications into one unit, rather than having to take out the line or the rotary for one application and the point laser for another” says Vareille. “We believe these all-in-one designs make for an even better user experience and will contribute to more and more users adopting lasers to increase their productivity.”

It’s important to note that one laser doesn’t necessarily meet every need. For example, you would not be able to get a plumb reference for can lights from the line laser used to level electrical conduits or HVAC registers. This is why laser levels are broken down into three categories: rotary lasers, line lasers and point lasers.

M e c h a n i c a l

B u s i n e s s

ROTARY LASER LEVELS Rotary laser levels are placed in the centre of a room, typically on a tripod, and project a laser beam in a 360-degree circle. This results in “chalk lines” on each wall of the room. Advanced rotary laser models may also feature a second laser beam for plumb applications. Rotary lasers are typically compatible with a handheld receiver that will help the user ½RHXLIMVFIRGLQEVOFI]SRHXLIVERKIEX[LMGLXLI laser beam is visible with the naked eye. Due to their greater distance capacity, these lasers work well for outdoor jobs or any job that requires a greater reach, such as larger commercial buildings.

• T he fu t u r e o f l a s e r l e v els • Typ es o f laser ser levels levels LINE LASER LEVELS Generally designed for indoor use, line laser levels are a more compact levelling solution that emit one or more plane laser lines directly onto a single wall or workspace and typically include cross-line capabilities, meaning the user can get both a horizontal and a vertical reference line. Like other laser levels, most line lasers have the ability to self-level, which increases their reliability on the jobsite. By eliminating steps in preparing workspace measurements, professionals can now easily set up a line laser level and dedicate more time to the job itself, such as aligning duct work.

POINT LASER LEVELS Point laser levels, also known as dot lasers, project up to six beams of light. This EPPS[WXLIYWIVXSVIJIVIRGITPYQFTSMRXWJVSQ¾SSVXSGIMPMRKERHLSVM^SRtal 90-degree level points for squaring. Rather than projecting an entire plane line, these laser levels mark a single position similar to a plumb bob. Devices with a self-levelling pendulum will, again, provide greater accuracy over manual levelling. Commonly used indoors, point laser levels are especially useful to replace the plumb bobs, which require a lot of time and effort to EGGYVEXIP]XVERWJIVTSMRXWJVSQXLI¾SSVXSXLIGIMPMRK-XMWGSQQSR TVEGXMGIJSV½\XYVIQEVOMRKWXSFIPEMHSYXSRXLI¾SSVERHVEXLIV than tediously climbing up and down a ladder to mark measurements on the ceiling, professionals can simply place the laser level SRXLI¾SSVQEVOMRKXSXVERWJIVETIVJIGXP]TPYQFVIJIVIRGITSMRXYT to the ceiling. This is especially useful when installing HVAC conduits. The added ability to project 90-degree points also makes for easier squaring when creating room partitions on the ground level.

An alternative look at residential options


n the January/February 2014 edition of Mechanical Business, I touched on what most consider traditional methods of residential water treatment, such as water softeners, reverse osmosis (RO) and ultra-violet (UV) systems (see Options Abound in H2O Treatment, Jan/Feb 2014, page 74). Let’s extend that look to some of the alternative and emerging technologies that are making their way into the mainstream.

Putting it to the test

Paul Ethier is the national sales representative for commercial products at Watts Water Technologies (Canada). He can be reached at

SOUND-ALIKES Absorption vs Adsorption Think of absorption as eating a lemon meringue pie and adsorption like getting hit in the face with one.

Results from a multi-phase study conducted by Arizona State University, in conjunction with The WateReuse Foundation, have cast a new light on the controversial subject of alternative water conditioning devices. Using the same source water, heating coils and identical testing rigs, including both an untreated and a traditional ion exchange control rig, the university tested the effectiveness of four different alternative technologies, TAC, Template Assisted Crystallization; EIP, Electrically Induced Precipitation; MAG, Magnetic Water Treatment; and CDI, Capacitive Deionization. All of the technologies tested showed a reduction in scale formation in household water heaters to some degree. As more testing is undertaken, the emerging field of physical water treatment and alternative methods of water conditioning will definitely be worth looking into.

SCALE CONTROL ALTERNATIVES: PHYSICAL WATER TREATMENT Homeowners, property managers, chief engineers, and facility maintenance personnel all face the same challenge in battling the ill-effects of hard water. Protecting a commercial plumbing system from damaging scale build-up, can bring considerable expense, both up-front and ongoing, to any commercial property. Ignoring scale control is never a good option because eventually the cost for equipment repair or replacement will offset the savings stemming from an absence of a control system. A number of alternative options that can be grouped under the term


M e c h a n i c a l


“physical water treatment” have been attracting attention of late. Physical water treatment (PWT) technologies work by changing the physical characteristics of the solution being treated, through with little or no change in the solution’s chemical composition. These technologies are chiefly used to reduce the negative effects of water hardness in plumbing systems, heating systems and appliances. The vast majority of PWT devices work to promote hardness crystallization (mostly CaCO3) in the bulk solution, so that it isn’t available to scale on downstream surfaces.

Ultrafiltration, or UF, is a relatively new water filtration process that falls somewhere between reverse osmosis and micro filtration in the filtration spectrum (~0.2-0.01um). It started its life in the 1970s as a pretreatment for high purity water applications, such as microprocessor and semiconductor manufacturing. Ultrafiltration has come into its own over the past decade with standalone point-of-entry and pointof-use “under-counter” drinking systems. In residential applications, there are relatively low rinse line requirements for POE whole house systems, and zero discharge is possible with the POU drinking water systems, which use an accumulative UF membrane that is replaced annually.

Did you know? The average Canadian consumes approximately 330 Litres (85 gallons) of domestic water each day.

PWT SYSTEMS TAC - Template Assisted Crystallization Template assisted crystallization is technology that influences the water solution at localized sites (on the media surface) such that hardness ions and their counter-ions (bicarbonate) combine to form inert nanometer-sized “seed crystals.” Called nucleation, this is where dissolved molecules or ions dispersed throughout a solution start to gather to create clusters in the sub-micron size range. When the remaining dissolved ions reach their solubility shift, they attach to the seed crystals and continue harmlessly downstream. While not an option for many closed-loop boiler systems, since there is no flow-to-drain, systems that incorporate a bottom blow down with scheduled daily discharges have been successful in controlling scale with this method while reducing or eliminating chemical additives. TAC media is always used in an up-flow design, which makes it not subject to low flow channeling or high flow pressure drops. The pressure drop as measured at peak flow rate is less than four psi. As with other resins, the media is subject to water chemistry limitations, such as chlorine, iron, manganese, tannins and pH levels. The effective life of the TAC media is three years and is neither dependent of the volume of water nor the hardness level.

MWT - Magnetic Water Treatment Magnetic water treatment is a physical treatment in which the water is subjected to a magnetic field to alter calcium carbonate adhesion properties. Most devices use a series of wires wrapped around a pipe. A voltage transformer controls the current through the pipe. By controlling the current, the magnetic field induced by the current can be reversed, causing cations to move to the centre of the pipe and anions to the wall of the pipe.

CDI - Capacitive Dionization EIP - Electrically Induced Precipition Electrically induced precipition is a physical water treatment process that uses an electric field to precipitate dissolved scale forming particles in the water. Precipitate forms on an electrode that must be cleaned periodically.

Capacitive dionization is an commercial electro-chemical water treatment process in which ions in the water adsorb to charged electrodes that have a high surface area, effectively removing them from the water stream. A few different designs of CDI devices have been developed, but they all include a forward flow adsorption/regeneration process, and a periodic backward flow cleaning and recharging process. Due to the high upfront capital investment and relativley high energy requirement, CDI is currently only viable as a commercial physical water treatment option.

A pressing issue


ipe joining has been undergoing a considerable revolution over the past few years, and the tools for creating the joints have been adjusting as well, with several companies now offering power tools to create press fittings for copper and stainless steel pipes. The reason for the rise in press fitting offerings is simply the speed at which connections can be made. Granted, that comes at a significant cost difference for the press-fit fittings, but many companies are adding the tools and flame-free option to their arsenals and doing the math on materials versus labour. If you are contemplating adding a press-fit system to your toolbox, there are a number of considerations to investigate, everything from jaw compatibility for size and brand of fittings, to the power of the unit. In general, the systems are available to press half-inch to four-inch copper, and half-inch to two-inch stainless steel. Jaw size range can vary from brand to brand, and some jaws will

press fittings from more than one manufacturer, so check the documents that come with the tools to ensure that the brand of fittings you use will work with the tool you are considering buying. Keep in mind that the number of presses per battery charge can vary a bit on conditions, but keeping plumbers pressing and minimizing battery changes – a pet peeve of cordless users – is the goal, so it can pay to look for tools that have “bigger gas tanks” (batteries Sponsored by Milwaukee Electric Tool – a proud with longer run-time). partner with Mechanical Business.
