Planning Policy the Right Way The rate of regulatory change in the mechanical sector has never been greater than what today’s industry continues to face. If you are building, installing or maintaining mechanical equipment, I know you’ve had to adjust to these ever-changing rules.

May/June 2017 Issue Published 6 times per year.

It is rare that changes are gladly embraced by all, but they are a little easier to accept when a standard or code has been revised for the right reasons, with an appropriate amount of research and industry stakeholder input.

Keeping the Summer Hot Watch for our WHAT hydronic supplement in the next edition of Mechanical Business, in print and online this July.

Take the changes to refrigerants, for example. I don’t think anyone in the industry felt the adjustments were easy as we moved away from CFCs. Most, however, will accept that the process had been handled with industry involvement and a ton of research and communication, which is helpful as we revise equipment choices and service practices on jobsites. Unfortunately, that’s not always how things go.

I ran into Canadian Hydronics Council chairman David Hughes during the MCEE show. He explained how a simple-looking change to a code is threatening the hydronic industry in Alberta, and could impact other parts of the country as well. Revisions to minimum under-slab insulation values – a move intended to improve a building’s efﬁciency – could result in building owners moving away from hydronic systems due to increased total building costs. The end result of this could actually achieve less efﬁcient buildings: talk about creating the opposite of the desired intention. Another example is out in B.C., where CIPH and other stakeholders have been vocal about some of Vancouver’s energy policies and strategies (see News, page 13).

Industry Meets for Another “Day on the Hill”

Jim Pattison Makes RecordBreaking Donation

Executive members of CIPH and MCA Canada met with parliamentarians and senior ofﬁcials at the associations’ annual Parliamentary Day of Awareness, held at Parliament Hill in Ottawa in April. The meetings, sponsored by former MB cover man Senator Don Plett, focused on passing Bill S-224, the Canada Prompt Payment Act, and the issue of harmonizing standards between Canada and the U.S.

Jim Pattison, the CEO of Jim Pattison Lease, has made history by donating $75 million to the St. Paul’s Hospital Foundation in Vancouver. The donation, announced in March, is the largest contribution made by a private citizen to a single medical facility in Canadian history. “On behalf of the Jim Pattison Foundation, I am proud to donate to St. Paul’s Foundation for a hospital that has been putting people ﬁrst in our community for more than 120 years,” Pattison said.

Worst Washrooms

Cooke Captivates HRAI Members Mechanical Business columnist Gord Cooke gave a lively presentation on building codes, radon and ventilation at the HRAI GTA Chapter meeting in March. Cooke outlined recent changes to the Ontario Building Code, before switching gears to talk about the importance of proper equipment sizing. “It’s time to recalibrate your thinking in terms of equipment sizing,” he noted, stressing the need for HVAC/R contractors to do proper heat gain/heat loss calculations. For more on sizing, check out Gord’s column on page 78. hrai.ca

Vancouver Rezoning Policy Causes Stir Vancouver’s Green Building Rezoning Policy came into effect on May 1, targeting a 50 per cent reduction in greenhouse gas emissions for new multi-storey buildings when a developer seeks a rezoning. The policy was met with considerable backlash, with many arguing that it would be impossible to meet the new emissions targets while using natural gas for space and water heating. “That’s what’s got everyone up in arms—the word on the street is that Vancouver is banning natural gas, which they’re really not doing, but they’re making it so difﬁcult to use it that it’s an effective ban,” explained Rob Waters, CIPH’s technical consultant for codes and standards. The city maintains that the new GHG targets can still be met using natural gas, and issued a statement noting “How a developer meets those targets is up to them; it can involve a mix of better insulation, thicker windows and better design, as well as opting for renewable energy.”

HRAI Shows off New Digs HRAI hosted an open house for its new ofﬁce space in Mississauga, Ont., in May.

The policy became an issue in the B.C. provincial election, with the Liberals promising to amend the Vancouver Charter if elected. The charter allows the city to set its own building code policies.

Proﬁle Jacques Deschênes: Balancing the Family Business

Like many in the plumbing, heating and cooling world, Jacques Deschênes got his start in business by joining his father’s company, Deschênes & Fils Ltée, a plumbing and heating wholesaler in Montreal. Working with his family since the 1950s, Jacques learned about business on the front lines. In the late ’70s, he launched an expansion plan that he and two of his sons, Martin and François, have continued to grow. Deschenes Group (GDI) now includes nine subsidiary companies operating more than 100 locations throughout Canada.

Q A Q A

Q A

What are some of the keys to success for a family business? The main thing, I think, is communication. You need to have good communication. This is the same thing within a marriage, or any relationship. And you have to learn when to talk business, and when to not talk about business. You need to make sure that one does not disturb the life of the other. Are there any guiding principles that have helped as Deschênes Group has grown? We always believed that the local needs are different, so we did not want to change how, for instance, Boone Plumbing was operating – the kind of service that they were offering. Same thing for Toronto – Bardon is not the same as Desco. They operate differently, and they have their own strengths. How did you prepare for your succession? When I reached 55, I decided that I would no longer be president at 65. It was suggested to me at the time that I should have an advisory board, and that I should not select my successor all by myself. The advisory board recommended that the successor should be qualiﬁed. So the children knew that if one of them was to be selected, they would have to go through testing and evaluation.

condos EXPANDING THE VRF UNIVERSE

ariable refrigerant ﬂow (VRF) HVAC systems are no longer considered a new thing. It has been more than a decade since the ﬁrst major global alliance was forged between a large Japanese VRF manufacturer and a North American HVAC manufacturer. Since then, numerous global alliances have been forged, and system offerings have increased throughout North America.

As a result, there are now large ofﬁce buildings, schools, churches, government buildings, medical buildings and, as detailed in my last article (see Mechanical Business Nov./Dec. 2015), a very large hotel in Canada that are using VRF for their main HVAC systems. There is precedence, there is track record, there is adoption; so what’s next for this technology? How about the condo industry? As a matter of fact, there are currently a couple of landmark condo projects in the Greater Toronto Area under construction that will be using air-source VRF as their sole means of space heating and cooling. Why did it take until now to look at the residential market, and why do we now predict that the next big thing for VRF will be in the condo industry? The answer revolves around two main points: reduced capital costs of VRF systems and new energy efﬁciency requirements.

THE JACK Set to be completed in the spring of 2018, The Jack is an 11-storey condo from Aspen Ridge Homes located just off of Yonge Street, south of St. Clair. The architectural beauty will feature a pair of large penthouses on the 11th ﬂoor, each served by its own dedicated VRF system. The rest of the spacious 100-plus units will be served by one of 20 heat recovery VRF systems located on the roof.

YEAR-ROUND EFFICIENCY

The VRF units are sized to meet both the cooling load and the heating load at the local design temperature of -20°C, with an assurance that the units can operate down to -25°C. To service the various condominium units, a and vertical VRF mix of horizontal hor will be used. fan coils w

On the cooling side, the efficiency story for VRF technology stems from the part-load efficiency of inverter compressors and in fewer heat exchanges that are present than in traditional HVAC systems. On the heating side, the COP of VRF averages between 3 and 4 over the winter. Considering that the COP of a furnace is always below 1, no matter how efficient it is, it should not be surprising that VRF is attracting attention.

A GREEN APPROACH

GETTING THE DEVELOPERS’ ATTENTION Technological advancements that do not result in construction cost savings usually need to have a meaningful impact on the salability or value of the units for a developer to consider them. Since homebuyers are more likely to be swayed by a highend countertop than a high-end HVAC system, the first driver for the general adoption of VRF by condo developers will most likely be based on the capital costs—which were more considerable five or 10 years ago—no longer being a large premium when compared to conventional systems. The capital cost of a VRF system, or of any HVAC system for that matter, is driven by two main things: equipment cost and installation costs. With VRF numbers on the rise in Canada, and with more manufacturers offering this type of equipment, the price has dropped significantly. I’d estimate that VRF equipment prices are close to half of where they were just 10 years ago. Of course, equipment cost was never the primary issue in the salability of VRF in condos. The installation cost and complexity of the systems – or at least, the perceived cost and complexity –was perhaps a bigger road block. A large proportion of mechanical contractors who install HVAC systems in condos have developed a comfort zone with the standard, water-based heating and cooling systems they have been installing. This can put them in a difficult position if a developer opts for a refrigerant-based VRF system. This change to the status quo can take a leap of faith for the mechanical contracting firm, and may require some additional training.

As politicians come up with policies aimed at de-carbonizing the Canadian economy, VRF technology could be a viable solution for comfort systems as all space heating can be accomplished without the use of fossil fuels. VRF is a technology that can help us make use of our electrical grid for heating in a very efﬁcient manner, due to the COPs, and this grid continues to get greener as utilities move to green options for generation, like wind, solar and other renewable energy sources. As such, VRF allows us to keep reducing our carbon impact. M e c h a n i c a l

HVAC THE EFFICIENCY PICTURE The VRF story in condos does not only revolve around capital cost savings. What is bringing VRF to the table, and what will continue to bring VRF to the table more and more, are increasing energy efﬁciency requirements in many parts of the country. For example, when applying for a building permit in Ontario, there are two general paths that can be followed to ensure that the project is in compliance with the energy efﬁciency requirements of the Ontario Building Code. One is based on the energy cost of the building, as compared to a standard building. The other is based on the energy use of the building, again as compared to a standard building. The latter ignores the sometimes volatile econom-

TRAFALGAR LANDING ics of the energy sector, and simply looks at how many units of energy the building consumes. This is where VRF technology can be attractive, given the COPs that VRF heat pumps deliver. And some of the newer VRF systems on the market can now operate efﬁciently at temperatures as low as -30°C, which increases the number of geographic zones where they can be an option for winter operation.

A short drive from downtown Toronto is Great Gulf’s Trafalgar Landing Condo project in Oakville. This set of three U-shaped four-storey buildings will make use of air-source VRF for all of their space cooling and heating needs. The structures will be served by three different banks of VRF units placed on the roof; one per wing of each building. And each condo unit will feature a vertical VRV fan coil in a small closet. The project is well underway and will be completed this summer.

PLUMBING UP ON THE ROOF I beg began to think that it would be a waste of time breaking more holes in the wall, so I went up on the roof to look for th the vent stack. Luckily for me, the vent stack had been instal installed to the top of the roof instead of tying it directly into tthe stack vent.

All of a sudden, the toilet started erupting like a volcano. A dark brown substance that was deďŹ nitely not lava shot four feet into the air, splattering on the walls and ďŹ‚oor.

Back in the day, our minimum roof vent terminations were only one inch higher than the roof. This tended to cause probl problems as most commercial ďŹ‚at roofs have gravel on them them. The gravel would eventually fall down the vent stack term termination and collect at the base of the stack, thereby plugg plugging the air vent.

The resident manager explained that this happened several times a day, making it impossible to rent the suite out. (No kidding!) He also noted that none of the four or ďŹ ve plumbing companies that had investigated the suite could ďŹ gure out how to ďŹ x the problem. Theyâ€™d tried to drain clean it but they couldnâ€™t ďŹ nd a plug in the drain. Theyâ€™d also looked for a plugged vent stack, which explained the holes in the walls, but they couldnâ€™t even ďŹ nd a vent stack.

So I ccalled in our vacuum truck and we managed to run 300 feet o of hose up to the roof and run it down the vent stack. It too took a bit of time, but we eventually vacuumed all of the ggravel out of the vent stack and resolved the excessive press pressure problem. I was also able to charge a fair amount for this job, since the landl landlord was tickled pink that we had solved the problem witho without damaging the property. He could now rent out the basem basement suite for the approximately $800 a month of rent that h he had missed out on for eight months. This made us look pretty good to our new customer, and we ended up main maintaining many of their properties going forward.

That gave me some information to work with, so off I went looking for that elusive vent.

COMPANY: Kogge Plumbing, Heating and A/C LOCATION: St. Mary’s, Ohio (Columbus area) CONTRACTOR: Rick Kogge FAVORITE PRODUCT: Viper

CUSTOMER TESTIMONIAL In business since 1952, Kogge Plumbing, Heating and A/C, Inc.’s mission is to ensure comfort for its customers by providing efficient, reliable and fast service. In order to provide a high level of quality, Kogge prefers Gerber® products. “We only stock Gerber toilets,” said Rick Kogge, owner of Kogge Plumbing, Heating and A/C. “The Viper™ is definitely our number one toilet; it’s an excellent flush for the money.” Viper toilets offer more than double the flushing capacity of the industry standard. Standard on every Gerber toilet for reliability is the exclusive Gerber mounting system with six points of tank-to-bowl connection that provide superior stability and allows for easy maintenance. “The mounting system for Gerber toilets means that I can carry only three designs of bowls and the tanks that I carry are interchangeable, giving me an inventory advantage,” commented Kogge. “I can stock bowls that cover standard, elongated and ADA height, and use different tanks with them, instead of having to keep a large selection of different tanks and bowls to match.”

Rick Kogge APPRECIATES: 1. Gerber’s commitment to only sell through plumbing distributors. 2. Time-tested quality and durability of Gerber products. 3. Unique designs, like the six point tank-to-bowl connection. ™

Viperr Comp pact Elongated. Compact HE-211-519 HE-21-519

Because of the quality and durability of Gerber products and the commitment to plumbers, Kogge stocks Gerber products and is confident in getting them quickly. “Gerber’s faucets are a quality, cast-brass construction. I am confident that heat and moisture won’t cause them to rot,” Kogge explained. “For the past 35 years we’ve used Gerber and we will only use Gerber bath drains. I know they won’t fail once they’re installed.” “Any faucet we order arrives in two days, so we don’t need to worry about long shipping wait times,” said Kogge. “We can’t keep every finish in stock, and other brands can take two weeks to come in.” “Overall, Gerber offers a very good value for the price with a great warranty,” summarized Kogge. “Because Gerber is committed to us and only sells through plumbing distributors, our pricing can be competitive.”

WHAT’S A

VENT STACK? In clause 5.4 of the 1980 NPC, it states that you must have a vent stack on a building that is more than four storeys and has fixtures draining from it. (In the 2015 plumbing code, the clause reference is 2.5.4.2.) A vent stack is basically an air pipe that ties the base of the soil stack to a vent that is run back up through the roof. The purpose of the vent stack is to relieve pressure at the base of the soil stack. On multi-storey buildings, a lot of head pressure (0.434 lb. per foot) is built up in the stack as waste rushes downward. As soon as it turns horizontal at the base, this excessive pressure needs to go somewhere. If the vent stack or air vent is working properly, the excessive pressure will release up the vent stack or air vent. If it doesn’t do that, the pressure will be released through the nearest floor-mounted fixture, which, in this case, happened to be the basement toilet. I can only imagine the surprise someone would have experienced if they’d been sitting on this toilet when one of those eruptions occurred…

KNOW YOUR CODE Since 1980, we have updated the plumbing code for vent terminations under section 2.5.6.5. Vent terminations now have to rise a minimum of six inches above the roof to prevent snow or gravel from entering the vents. There have been changes to the vent stack rules, too. We now recommend tying up to eight ﬁxture units into the base of the vent stack to help scour the bottom wye connection, which helps keep vents from plugging—and also helps reduce the risk of those nasty toilet volcanoes.

What’s in Your Job Description?

itles and job descriptions can play an essential role in any business. They help define the skills, purpose, responsibilities, decision-making abilities and the brand personality of your company.

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@ mechanicalbusiness.com.

Despite all of the modern-day business philosophies that claim we don’t need a title to do our jobs, I have learned that organizational charts and job titles speak to the fact that a business needs structure. When you dig deeper, titles can strongly affect the purpose and ambitions of employees, and can be drivers for performance and success, but more important than a title is the job description, since that’s where responsibilities and accountability are outlined. To be honest, I have found that some use job titles as expressions of ego, rather than as an accurate descriptor of what performance is expected. But when properly applied and managed, titles and job descriptions can set milestones for people to aspire to within your organization while giving customers a clear understanding of a person’s role in the full experience working with your company.

SAME TITLE, DIFFERENT RESULTS Why don’t all employees get it? It usually comes down to us, as leaders. Have you created a compelling vision for your organization that will get your people out of bed in the morning?

Guidelines, Not Rules Job descriptions are important to identify specific duties – as an example of what an employee will do from day to day – but a job description is never complete, and it’s not a contract. I always add “other duties as may be assigned from time to time” to the end of every job description. This allows you to make changes without having to create a whole new description.

M e c h a n i c a l

Do they know why they are doing the things you ask them to do? Are they empowered to make the decisions they need to make for the business to be successful? Are they comfortable making mistakes they learn from and don’t repeat, or are they afraid to push themselves for fear of punishment? Have you built solid processes and procedures for the basic and everyday tasks so that they can focus their time on the things that really matter, like finding a creative solution to a customer’s problem? The same job description can yield very different results depending on how these questions are answered. These questions – and so many more – are in our job descriptions as leaders. I was at a conference this spring where a speaker had built rock-solid processes in his business that added $5 million to the purchase price when he sold it. He even had a process for changing a roll of toilet paper because CSRs working on the weekend were more focused on toilet paper than they were about serving customers. In his company, every activity worth doing had to improve the top line, bottom line or customer experience. He cited an example that they had almost finished loading two tractor trailers full of goods on a Friday when a shipping clerk discovered that one of the address labels did not look right. The bar codes were correct but the names were wrong. The product would get to the right customers, so not a major concern really, but the customers would think they got the wrong package.

B u s i n e s s

Provide a Pat on the Back

The owner asked the staff what they felt they should do and the shipping clerk just said one thing, “We do it right, and we do it with style.” (That just happens to also be the company’s vision statement.)

Do you recognize your people for doing things right?

Without any discussion, everyone knew what they had to do. They unloaded, re-labelled and after six hours of overtime from everyone on a Friday night, they got everything done. That is empowerment, but it also illustrates clarity of focus. Every employee was in tune with the mission and felt empowered to do what they needed to do. Would that happen in our companies? Do we all have the clarity of a compelling vision and the willingness to empower our employees to deliver on that vision? At the end of the day, the silver bullet in our organizations is us. We set the vision and mission. A sense of purpose is the strongest motivational force there is. We establish and document the processes and procedures in our companies. Get rid of your organization chart that focuses on job titles and replace it with a responsibility and accountability chart. Then empower your employees to deliver on your mission/vision.

Nothing means more to people than being liked and approved of. Our biggest fear as human beings is that we are not good enough, so a good leader knows when to stand up and applaud. As owners and managers, we have the ability to influence our people. We must give them clarity of vision. We must provide purpose for meaningful work, so that they can get aligned with their own reasons for getting out of bed in the morning. Wrap that up with recognition for getting things right and you have a winning formula that will deliver on your company’s vision and value statement – and no one will ever tell you something is not their job.

CUSTOMER SERVICE IS JOB #1 The four worst words in the English language are “it’s not my job.” I’m generally a pretty calm person but that statement can put me over the edge, especially if it is from a management-level employee. In most small- and medium-sized businesses, it is everyone’s job to see that the customer is looked after.

Finding the

Comfort Zone We are all in the comfort business, and exploring custom options with your customers will keep you ahead of the competition, not to mention earn you a reputation for being a comfort specialist.

popular selling and marketing feature of hydronics is the ability to have unlimited control. With a piped system, the ability to zone individual spaces or rooms is a simple proposition, or it can be with a little bit of prep work.

Most job quotes or bids start with either a site visit with the property owner, or a look at a set of proposed plans from a designer. At this early design stage, involving the owner of the project is a wise step. They are the ones whose idea of comfort will become your target, so speaking to them is one of the best ways to ensure that you have happy, comfortable customers after system zoning is properly applied. We all have different comfort expectations and wants, so allowing the occupants the ability to customize their environment shows the competency of the installing/designing contractor. Sorting out how to create and control each zone will lead to an almost endless list of options and configurations, but in a very basic way, we can look at zoning as simply installing “switches” and connecting these to temperature-sensing, user-friendly and adjustable controls in the spaces. Switching, or controlling fluid flows, to a hydronic pro, will involve the choice of a zone valve or actuator on a manifold, or a zone circulator.

Bob “Hot Rod” Rohr has been a plumbing, radiant heat and solar contractor and installer for 30 years. A longtime columnist and trainer, he is manager of training and education with Calefﬁ North America. You can reach Hot Rod at bob.rohr@calefﬁ.com.

CHOOSE WISELY The decision about which control method to use, or is preferred, has been going on for decades. There is no one-sizefits-all choice, so an assessment of the system and where the components will be placed can be very helpful to your planning process. Look at flow rates and the pressure drop of the circuits as you design the system. Consider where the switches will be located, and how accessible they will be for future service. Energy costs to power the switches should also be considered. Today we have both low-energy-consuming circulator pumps as well as zone valves. Is noise an issue? Some motorized valves create just enough noise to annoy an owner, and switching relays for zone circulators can also click loud enough to bother light sleepers. Thermal-type actuators on manifolds are about the quietest way to switch flows on and off, so these are often installed when the switch will be located close to sleeping areas.

In recent years, the selection of circulators has greatly increased. Smaller-flow circs are widely available, and the industry is shifting toward ECM, low-power consumption offerings. Today’s large selection of pumps makes zoning with circulators or zone valves a workable and efficient choice. Ideally, you should size circulators to work at mid-range in their pump curve.

HYDRONICS oversized circulator never makes sense. Variable ﬂow circulators rs with automatic balance valves provide an excellent application for large commercial applications. Think: large hotels. Zone valves have also seen some unique upgrades over the last several years. On the thermal actuators side, virtually all 0 manufacturers offer low-power consumption models, and 250 mA actuators are common now. This allows for more actuatorss per transformer to reduce the power consumption, but be aware that low-power consumption thermal actuators take longer too fully open. Motorized zone valves continue to be a go-to choice for most systems. g A wide choice of sizes and connections are available,, as are voltages. Relay boxes that can be used with both pumps and zone valves are also being modernized. Some of the recent upgrades to xes these workhorse boxes include multiple setss or dry contacts, connection ti ports to link multiple boxes, front-facing indicators, thermal overload protection that replaces fuses, online capability, outdoor reset capability and more. I highly recommend the use of these boxes since they eliminate wiring error, provide fused protection, reduce labour and cleanup the wiring management in the room. The ball is in your court when it comes to deciding on zoning options. Look over the choices and offerings, and your system, and put all the choices to the test. And keep in mind that many installers choose products based on local and factory support, which isn’t a bad idea either. So, talk with your customers, assess both their expectations and the system you are designing, and I look forward to ﬁnding you in the comfort zone.

Money-Saving Options The ability to control sleeping areas at different or setback temperatures is a crowd pleaser since reducing temperatures to seldom or less-used spaces can lower system operating costs. And the zoning parameters can be reprogrammed as the need for each room or zone changes. Is the nest emptying? No problem, just reprogram the zone.

D DEFINING THE ZONING TARGET Z Wondering what to focus on W w when assessing your customer’s need needs? A good starter is to ask about curre current and anticipated building use and occupancy. o

CAUTION! Extensive zoning, and especially micro zoning, should not be undertaken without some careful consideration. While zoning a small bathroom space may seem like a great comfort option, it will have an impact on the rest of the system. Even with today’s modulating equipment, it is possible to short cycle the boiler or heat source. A short cycle is generally thought of as a run cycle of less than 10 minutes, which is rather inefﬁcient. One rule of thumb to combat short cycling is to size the boiler so that the smallest zone matches the lowest turndown rate of the boiler. While this is a wise guideline, remember that is still based on design day conditions, which represents less than 15 per cent of the heating season in many areas. As such, a buffer tank may be an option worth considering, since it can smooth out a boiler’s ride. The boiler, or heat source, sees this tank as the load, while the distribution side sees it as a thermal battery. The buffer can supply heat to the small zone several times before the thermal battery needs to call for heat from the boiler. Online calculators or textbook formulas can help you size a buffer tank to greatly lessen boiler and premature equipment failures caused by frequent cycling.

PLAN FOR THE FUTURE All mechanical and electro-mechanical devices fail at some point. Easy access and proper isolation will allow for quick and efﬁcient service in the future. As part of your installation process, document and provide a map of the system to easily identify remote manifolds or valves.

n Canada, there’s only one guarantee in life outside of death and taxes: the changing of the seasons. And yes, despite an almost balmy winter in some parts of the country, the seasons have changed again. With the dog days of summer fast approaching, we now find ourselves entering cooling season. As always, new technologies and evolving government regulations leave the cooling market in a constant state of flux. So what can we expect from this year? We talked to industry experts to find out.

Wall-Mount Mini Splits Fujitsu’s wall-mounted ductless mini split systems are available in three models ranging from 9,000 to 15,000 BTUH. Offering cooling efﬁciencies as high as 33 SEER, the Wi-Fi enabled systems offer remote operation. One mobile device can be used to control multiple indoor units. fujitsugeneral.com

Embracing IoT The savvy HVAC/R contractor realizes that succeeding in business means keeping your ear to the ground when it comes to consumer trends. “Homeowners require assurance that their investment is sound from a reliability standpoint, and provides the fundamental needs for improved comfort, humidity control, and inside air quality,” explains David Palazzolo, Daikin’s residential cooling product manager. “Recent industry trends lean toward the Internet of Things and whole-home solutions that provide increased energy savings.” Indeed, smart thermostats and their integration into IoT continue to drive sales.

Mini VRF Systems Haier’s Mini VRF systems are designed to bridge the gap between small multi-zone residential applications and multi-zone light commercial needs. Available in sizes ranging from three to ﬁve tons, they can connect to up to nine indoor units. haierductless.com

“Smart thermostats continue to see robust growth, especially as price points come down for various options and as the thermostats integrate with hardware systems such as Amazon Alexa and Google Home,” says Jeff Underwood, Goodman’s vice-president of marketing. “We continue to see Wi-Fi enabled thermostats making up a greater portion of our distributors’ sales.” And the controls aspect of the market only shows signs of growing. “Some of the latest advancements use voice-activated commands with thirdparty products to control an HVAC system, as well as the lights, sound system, and many other features within a home,” says Palazzolo. “This is creating a higher interest for consumers to interact with their HVAC systems.”

Governments continue to push for higher minimum efficiencies for cooling equipment, and consumers have responded by adapting their purchasing habits. “We’ve seen demand for systems stems with higher energy efficiency gradually grow from year to year as homeowners wners search for options that will help lower monthly utility bills, and the overall cost ost to operate their home,” Underwood notes. Of course, not all homeowners ers will opt for the highest of the high-efficiencyy options available to them. The cost of going ever-more efficient with th equipment can be impacted d by other factors, including how ow long a family plans on living in its current residence.

Wi-Fi-Ready Air Conditioners York’s Affinity YXV air conditioners are available in sizes ranging from two to five tons and offer efficiencies as high as 20 SEER. Communication between indoor and outdoor units allows contractors to quickly identify and diagnose system issues. They can be paired with the Affinity Hx thermostat for Wi-Fi control. york.com

“Consumers are always interested rested in higher efficiency, but they have to choose just how high as compared to the payback they might expect,” Palazzolo says. “People don’t live in the as long as they highly h same house h l h used d to, so a hi hl efficient system with a 10-year payback might not be of interest to many people who know that they will not be in the home that long.” Climate, too, plays a role in determining what efficiency level best suits a customer. Short cooling seasons mean long payback periods. “I live in Northern Ontario. If that’s where you live, is a 16 SEER or a new 18 SEER air conditioner really going to save you that much money?” posits Mike Cantin, Napoleon’s director of North America sales for HVAC. “But consumers are still looking for the best value for their dollar. I believe people are willing to pay more if they believe they’re getting more value for what they’re buying.”

Central Air Conditioners Napoleon’s 16 SEER central air conditioners are available in 1.5 to 5 ton sizes. Their fan blades are designed to maximize airﬂow while reducing unwanted noise. They feature scroll compressors with built-in temperature and pressure protection. napoleonheatingandcooling.com

Heat Pumps Gaining Ground Heat pumps and ductless systems continue to make signiﬁcant inroads in the Canadian market, notes Nick Shin, Haier America’s vice-president and business unit leader, Ductless and HVAC. “Ductless systems in North America in the past ﬁve years have been growing somewhere around 17 to 20 per cent a year, which is tremendous when you consider the housing market is pretty steady,” he says. “A lot of designers and architects are now designing buildings with ductless systems.” And technological advancements have allowed heat pumps to operate in heating mode when external temperatures dip well below zero, making them an attractive option for year-round heating and cooling for all but the most extreme winter days. “Heat pump products were once thought of as being used only in the Southern United States,” notes Daikin’s David Palazzolo. “Today, some of the fastest growing heat pump markets are in Northeast and Northwest U.S., and Canada.”

Variable-Speed Heat Pumps KeepRite’s ProComfort Deluxe 18 heat pumps are available in cooling capacities ranging from two to five tons. Providing efficiencies of up to 19 SEER, they offer five stages of variable-speed compressor operation. Units can be controlled remotely via Wi-Fi. gokeeprite.com

Troubleshooting Made Easy The beneﬁts of smart thermostats don’t extend only to home and business owners—they’re a huge help to contractors as well. “All the commissioning can get done through a lot of the thermostats now,” explains Alain Boudreau, Allied Air’s district sales manager for Eastern Canada. “So you’re going from spending 25 to 40 minutes commissioning a system to getting it up and running in about eight or 10 minutes now. “The other big bonus for the contractor is that you can’t miss a step with these thermostats. It walks you through the commissioning process step by step so that when you’re leaving, the system is set up the way it should be.”

Vertical Blower Coil Trane’s BCCD compact vertical blower coils offer cooling capacities ranging from 20,000 to 100,000 BTUH. The single-zone VAV systems are suitable for use in spaces with varying occupancies. The service panel is located at the front of the unit to facilitate installation and troubleshooting.

Self-diagnostics in modern cooling systems can also save contractors a lot of time. “Our products have a fault code that can, for example, tell you that your refrigerant is low or that something is wrong with your communication wire,” Shin says. “We’re adding in this technology to help installers and service people. Contractors can have a great idea of what the problem is before they even get to a home.”

And once you’ve got the error code, diagnosing the problem is easier than ever.

Homeowner Interest on the Rise Until recently, many consumers took little interest in how their home’s cooling products worked or looked. But that is starting to change. “Historically, HVAC systems might have been thought to be low-interest consumer products,” notes Daikin’s David Palazzolo. “However, with advancements in technology, consumers have become more interested in and aware of their HVAC systems and how they are performing.” He attributes this to the rise of smartphones and apps that allow homeowners to easily access, monitor and control their systems from outside the home.

Single-Zone Heat Pump Systems

Style has also become more of a focus for consumers, with manufacturers of ductless systems making the aesthetics of indoor units a point of emphasis.

Daikin’s Aurora single-zone systems are designed for spaces needing additional comfort conditioning, and can service areas up to 1,460 square feet. Available with wall- or floor-mount indoor units, they offer cooling efficiencies of up to 20 SEER.

“We’re developing a broader array of products,” explains Nick Shin of Haier America. “Before, it used to just be a simple indoor unit hanging on the wall. Now we have cassettes that go up in the ceiling that have a nice, ﬁnished look. We even have a hybrid product that is ducted where you can run duct through a couple rooms.

he primary objective of a vacuum cooling system is to form a cold trap to remove excessive moisture from the air before it reaches the vacuum pumps. However, the system conﬁgurations that are able to accomplish this vary signiﬁcantly.

Direct expansion (DX) or ﬂooded systems may be used, and refrigerant options include ammonia, an HFC or even a hydrocarbon, such as propane. Generally speaking, ﬂooded systems typically use ammonia and most DX systems installed to date seem to have relied on R-22, although this is not always the case.

look as shipping containers. rable This is because they must be of durable construction and also be able to withstand the pressure difference between the outside and inside when the chamber is in a vacuum.

Generally speaking, flooded systems typically use ammonia and most DX systems installed to date seem to have relied on R-22.

Additionally, vacuum cooler chambers are often installed outdoors. As such, the chamber must be weatherproof. The chamber must be hermetically sealed in order for it to reach the required vacuum level. To create and maintain a good seal, hydraulically operated doors with seals are commonly used, although there are options on the style of doors. Some chambers use hinges, while others have sliding-type doors.

THE COIL BOX A coil box is commonly used in both ﬂooded and DX systems. As the name implies, the box is simply an enclosure that surrounds the coils in a way that permits airﬂow to be directed through the cooling coils with minimal or no bypassing of air around the coils.

THE VACUUM PUMP SECTION

The coil box is placed between the vacuum cooler chamber and the inlet to the vacuum pumps. When the system starts up, air from the sealed vacuum chamber is drawn through the coil box, where the moisture is removed. After the air leaves the coil box, it enters the ﬁrst stage of the vacuum pump(s).

To achieve the level of vacuum required, either a two-stage high-vacuum rotary pump module or a module that includes both lowstage pumps and high-stage pumps is used. The two-stage high-vacuum rotary pump is similar to the two-stage vacuum pumps used in air conditioning and refrigeration service, but they are usually much larger and equipped with built-in oil pumps. Other systems use separate low and highstage pumps. In these systems, the high-stage pump may be referred to as a “booster,” “dry” or “roots” pump. This typically has a rotarylobe design and will be the first vacuum pump that the air enters. Only the high-stage pump operates when the system first starts up. These are high-volume pumps designed to reduce the air pressure to a level that will allow the low-stage vacuum to pull the air pressure down to as low as needed. The low-stage pump is referred to as a “backing” pump. By using the roots pump in the first (high) stage, there will be much less moisture entering the booster pump. This results in less moisture to contaminate the oil because air from the high stage leaves the pump through a valve that is open to atmosphere. Once the chamber pressure is reduced to a predefined value, the atmospheric valve is closed and the backing pump starts up. At this point, both pumps operate in series to achieve the final chamber pressure.

entrainment is greater when the backing pump is exposed to higher inlet pressures.

HOW IT WORKS Looking at a sample system handling produce, the pressure within the chamber would be reduced to 5.82 Torr to induce evaporation of the water within the chamber at a temperature of 36°F. At some point just before the water begins to evaporate, the refrigeration system must be started up. This is important because a relatively large amount of moisture will enter the pump if there is no cold trap to remove it. The backing pump typically has a mufﬂer at its outlet. This mufﬂer often has an oil drain because oil could be entrained in the air. The possibility of oil

A rapid cooling technique, vacuum cooling works well for porous products with high water content, like leafy vegetables.

The vacuum chamber or pipe feeding the vacuum pumps is usually equipped with an atmospheric vent valve. After sufﬁcient moisture has evaporated from the product to result in the desired ﬁnal temperature, the vacuum pumps are turned off and the vacuum cooler is vented to atmosphere.

PLUMBING By Greg Dalgetty

on the go A SHIPLOAD OF

hen most of us think about toilets and plumbing, houses and commercial buildings spring to mind, but these ﬁxed structures are not the only locations where nature calls, and is served. With planes, trains and boats equipped with washrooms standing at the ready for passengers in need, plumbing can be a mobile experience. And, just like the washrooms in your home, they can get backed up from time to time. Howard Cohen, the owner of Monsieur Drain, a Montrealbased 24-hour drain-clearing service, is no stranger to backed-up toilets and clogged drains. He’s pretty much seen it all throughout his career—but there’s one job in particular that stands out, and not just because it was on the water.

They couldn’t leave port with the drains blocked up, so the guy told me to do whatever I had to do to get it fixed.”

A RACE AGAINST TIME

When you’re ship out of luck, try giving Howard Cohen a call.

Most plumbers have a set of “interesting job” stories, but Cohen has one that could even get Mechanical Business plumbing columnist Fred Bretzke to cringe. This one took place on a cargo ship, where the sewage was so severely backed up that the waste in the pipes had solidiﬁed into a granite-like substance, rendering conventional drain-clearing tools useless. “We went there for just a standard service call to unblock one sink and a shower in one of the cabins,” Cohen recalls. Little did he realize at the time that the job would be much, much more than that. Cohen’s client was a large ship docked at the Old Port of Montreal, but it wasn’t just any large ship. It was a crane ship that had spent decades cruising the St. Lawrence River, hauling cargo on and off other freight ships. “It must have been at least a 100-ton ship,” Cohen says. “The crew on the ship wasn’t big—there were maybe 10 or 12 guys who worked on it—

on the go

but it was a very long ship. It took time to walk from one end to the other.” Cohen arrived at the scene to see what he was up against. “The ship had been sitting in port all winter. When a ship is sitting in port and it’s empty, the bow is up, so the sewage on the ship doesn’t flow properly. It all flows by gravity on those old ships, whereas the new ships use things like suction.” Cohen investigated the cabin in question, only to find that the sewage problem was worse than the crew had originally thought. “It turned out six cabins were all blocked up,” he explains. But this wasn’t just a case of unclogging multiple drains—it was also a race against time. The crew was due to set sail in a day and a half, and going to work without properly functioning toilets was simply out of the question. “They couldn’t leave port with the drains blocked up, so the guy told me to do whatever I had to do to get it fixed,” Cohen recalls.

ROCK-HARD ACCUMULATIONS OF HUMAN WASTE The situation in the ship’s piping was grim, and time most certainly was not on Cohen’s side. “I actually wanted to leave the job,” he says. “I didn’t want to take it because it was a big job and it was the ﬁrst time I had ever worked on a ship.” But, never one to back down from a challenge, Cohen soldiered on, calling in a six-man crew to help him get the job done. “We had only a day and a half to do it, but I was told to do what I had to do to get it done, so I called up my guys and we worked through the night.” However, that night didn’t go exactly as planned. “We tried to use rooters and pressure to remove the blockages, but it just wasn’t going anywhere,” Cohen

IT WAS GROSS Cohen was left with no choice—he’d have to do things the hard way. And besides, who needs an augur when you’ve got a saw and a big piece of steel? “We cut the pipe with saws, and then just started banging away at the solid waste with a 14-foot steel rod,” he explains. “Every 12 feet, we would cut the pipe and drop it. Then we would bang out all the crap that was inside, and we’d put the pipes back up with mechanical clips.” It was a crazy idea—but just crazy enough to work. And so it went, all night and all day— cutting out pipe, knocking out crap and moving on to the next section.

Cohen’s son, Maxim Boguslavschii, was a member of the team who worked on the ship.

explains. “We tried passing the rooter through, but it was just spinning. The blockage was solid. In some parts of the pipe there were two or three feet of solid blockage.” The ship had been docked in port without any cargo for the entire winter, and the bow had risen. Consequently, the drains had developed a negative slope. But, negative slope or not, the crew still had to go to the bathroom.

Cohen explains. “They’d be ﬂushing the toilets, but there isn’t a lot of water used when you ﬂush those kinds of toilets, so the waste would go down and just stop in the pipe. And it would build up and build up until it just got hard like a rock.” Rooters and pressure blasts were no use against these rockhard accumulations of human waste. Cohen needed another solution. And he needed it fast.

“They had just kept on using the toilets, and at one point the toilets stopped working,”

“We banged it all out onto the ﬂoor and swept it up, because it was all dry. It was gross, but we got them out on time,” Cohen says. “When we put all the piping back up, we pressure-cleaned the whole line just to get any debris that was left over.” They not only got the job done, but had some fun along the way. “I’m a boater, so for me it was fascinating to see the inner workings of this huge ship,” Cohen explains. “It was crazy. I’ve been on cruise ships, but it was cool to go down to go down into the belly of the ship and see all the engines. The diesel engines are huge.” And after an exhausting all-nighter of manual labour, the crew was able to set sail. “We wouldn’t let them down. We got them cleared out, and off they went.”

CELEBRITY ENCOUNTER By Greg Dalgetty

enry Burris is no stranger to performing under pressure. In fact, he excels at it.

The decorated quarterback enjoyed a CFL career that spanned 17 seasons, winning three Grey Cups, two Grey Cup MVPs and two Most Outstanding Player awards along the way. He ranks third all-time in the CFL in passing yards and touchdowns thrown. These are no mean feats, considering the intense pressure quarterbacks face on the gridiron. Recently retired from pro football, Burris now faces a different kind of pressure—the pressure of live television. After announcing his retirement in January, the Oklahoma native joined the on-air team at CTV Morning Live Ottawa. Now he starts his days at 3:00 a.m. and greets viewers in the nation’s capital with his boundless energy and trademark smile.

“All the skills I learned from the ﬁeld—teamwork and how to prepare for game days—have prepared me for this opportunity,” Burris, 42, explains.

“Playing football—and especially being a quarterback—there’s a lot of pressure on you to make the right decisions on the ﬂy,” he says. “Despite how crazy live TV can get, like when breaking news occurs, you have to stay poised and focused on the job at hand.”

Going Out on Top

Another Form of Art

The 2016 CFL season was tumultuous for Burris, to say the least.

It’s not so surprising that Burris has ended up on TV.

After being named the league’s Most Outstanding Player in 2015—a season that saw him break records for most completions in a season and a single game while leading the Ottawa Redblacks to first place in the East Division—Burris was sidelined by an injury to his throwing hand in the first game of 2016. He was replaced by backup quarterback Trevor Harris, but Burris eventually returned to help the Redblacks back to the top of the East—and back to the Grey Cup—for a second straight year. After falling to the Edmonton Eskimos in the 2015 Grey Cup, the Redblacks were up against the league-best Calgary Stampeders in 2016. No one gave them much of a chance to win the game and, as if things weren’t looking grim enough, Burris injured his knee just prior to kickoff. Never one to shy away from adversity, however, he soldiered on, leading the Redblacks to a thrilling 39-33 overtime victory—and their first Grey Cup. With the championship on the line, he passed for 461 yards, threw three touchdowns and was named MVP of the game. “I’ve always been a guy who wants to be in the underdog scenario,” Burris says. “For me it had been almost 10 years since I had won a Grey Cup, and to be able to finally make it happen again in my last season—my final season, my final game—talk about a blessing coming true.” Of course, at the time, Burris hadn’t decided whether it would, in fact, be his last season. He attended the Grey Cup parade on crutches—the knee injury he’d suffered before the game was no joke—and told fans in attendance that he’d wait until the New Year to decide on his future. In January of this year, he finally decided to hang up his cleats. It wasn’t a decision that came easily. “It’s never as easy as it seems, because once you win, there’s still that competitive side of you that wonders if you could do it back to back,” he explains. “Those thoughts were going through my mind. I’m not going to lie and say I didn’t think about it.” But ultimately, the opportunity to go out on top following one of the best performances of his storied career was too good to pass up.

He studied broadcasting and communications at Temple University in Philadelphia while he was setting records for the school’s football team—and he certainly has the personality and charisma for live television. But before he started his studies, he worked for his uncle’s residential construction company, helping build houses. He credits the discipline and work ethic he developed on the jobsite with setting him up for his future successes. “Being able to learn those skills at a young age helped develop me into becoming a quarterback and made me able to do the things I do today,” he says. “It was a lot of hard work and manual labour, but in the end you got to see how it beneﬁted the homeowners when they moved in.” And along the way, he gained a special appreciation for the trades. “To me it’s just another form of art. There are many great artists in this world doing different things, from the mechanical side to the homebuilding side, to making music, playing football and doing live TV. It’s all art in its own way. It comes from hard work and preparation.”

THE KEY TO RADIANT FLOOR SUCCESS

T Surprise! It’s Carpet. One of the largest design dangers I’ve encountered recently is a complete disregard for the specifics of the floor covering in the design. Designers will often pick a default R-value for the flooring, such as 1.4, which is okay for thin carpeting with light padding, most laminates and some hardwood flooring. If the radiant system suddenly faces shag carpeting or solid wood planking, however, the responsiveness or efficacy of the heating system is going to take a nosedive. I know of a recent project in B.C. where an R-value of 0.4 was used for the flooring, which would work for thin vinyl or similar types of coverings. Unfortunately, a great number of rooms in the suites were specified with carpet, and no one told that to the hydronic system designer. Based on limited specs, and a maximum temperature specified at 110°F – with boiler, pumps and piping all specified, purchased and installed to suit that requirement – there was no simple way to adjust the system to push more heat upward, and I’m sure the fix was on the pricey side.

here are many things that can get in the way of an otherwise perfect radiant ﬂoor installation, but good communication and proper forethought can help keep your customer satisﬁed for years to come.

To help avoid surprises, here are a few issues to be aware of, so that you can ask the right questions of your customer, and pass the right information along to your designer.

heat he eat gain in the flo floor or One major problem can stem from concrete thickness above a radiant system. Thick concrete doesn’t usually impact a floor’s ability to deliver heat, but it will affect its responsiveness. The biggest problems with thick floors happen when the room also has solar gain. This can happen with south-facing windows. Not only does a thick slab react slowly, but it also absorbs solar gain, stores the heat and then continues to emit BTUs long after the thermostat has been satisfied. What’s one of the worst combinations? How about when a homeowner decides to swap out their existing floor for black slate tiles? If that’s above your radiant installation, don’t be surprised if you get call backs about overheating.

So, ﬁnd out what ﬂooring (and underpadding) the customer has in mind and ensure that the designer knows it!

Unintended direction of heat delivery can be a problem with staple-up systems. If insufﬁcient insulation is placed beneath the pipes too much heat can go downward rather than upward.

Why take the chance? Insulation in the right place, preferably with some reﬂective foil bubble insulation as the closest layer to the pipe, can help a great deal to make your installation a successful one. One caution that I’ll add, however, is that if the foil bubble insulation is touching the piping you are allowing the foil to conduct heat downward and through the foil, rather than encouraging heat to bounce upward.

Modulating Boilers

reduce Wear and Tear

I really (really) think modulating boilers are a good idea. Notice I don’t say “mod-con.” That’s because there are installations where your supply temperature won’t be in the condensing range very often. This can happen, for example, in low-rise apartments with baseboard heating. In reality, the building will not need the full capacity of the boiler for most of the year, and the more often it cycles, the greater the wear on the ignitor, circuit board, relays, pumps, and – well, you get the picture. That’s why it’s handy to have a boiler that can ramp down its capacity, even if it doesn’t get into condensing range all the time. Minimizing any replacement and maintenance costs can help our industry continue to sell hydronic systems, so ﬁnd a modulating boiler that you like and offer it to your customer.

Getting a little

loopy Having loops that are slightly longer or shorter overall isn’t usually a large problem. Pumps and piping can always be adjusted, but piping isn’t something that is going to add any maintenance costs, so I always advocate spending a bit more on piping. Why not add a few more loops and save your customer a pump size or two? And remember, the more your customer spends on

designer

OUT maintenance over the life of the system the less happy they will be, and the less likely they will be to advocate for radiant. The other hidden cost with pumps is electrical use. While a single pump doesn’t use much power, in some of the bigger systems, especially commercial ones, the electrical costs start to add up. It’s also annoying to balance a system where the pipe lengths

are uneven. In practice, you’re going to have rooms that end up hotter or cooler than you expected, and throttling ﬂow is one way to adjust that for the customer. If you haven’t left yourself room to do this because you have already used that wiggle room to adjust for random lengths, you have one less way to satisfy a grumpy customer.

Be aware that the hydronic system designer almost always has imperfect information when working on a layout. Even if they have tons of information, they may not have tons of time to sift through it all, so they could miss something.

ome people struggle to ﬁnd their calling, ﬂitting around from job to job without any purpose. But that wasn’t the case for Suzanne Graham.

“I always tinkered with things when I was younger,” she says. “I knew I wanted to do something with my hands—I just didn’t know what.” It didn’t take long for her to ﬁgure it out. After considering several trade options, she applied for an HVAC pre-apprenticeship program through UA Local 787’s Joint Training and Apprenticeship Committee in 2003. “Out of 200 applicants, I was one of 20 people who got chosen to take the course,” she recalls. “It was an extensive interview process, plus we had to do testing to see if we were mechanically inclined. I was the only girl in the class. There other 19 were guys who ranged from 18 to about 35 years old.”

What’s your favourite area to be dispatched to? I’m a city girl so I like being in the downtown core. I like the hustle and bustle, although the parking sucks. Favourite tool in your toolbox: My most prized possession—my favourite thing in my tool bag—are my safety glasses. If I don’t have my safety glasses, I’m not working. As soon as I get out of the truck, I put them on and don’t take them off until I’m done the job. And I love my drills. I love anything that’ll cut, demolish, break, destroy or dismantle. What’s your favourite thing about the trade? It’s the variety, but it’s also the unknown. You get a service call saying a furnace isn’t working. Finding out why it isn’t working is so intriguing to me. Especially when they’re sending me to a call that no one else can figure out—I’m all over it. The sense of accomplishment when you figure it out is like nothing else. What do you do for fun? I go to the gun range a lot. I’ve shot a sniper rifle, an BMG50—those things are huge and they can go a bit crazy. You have to sit down in a chair and prop the gun up nice and tight into your arm and hold on to the thing. You become the gun, pretty much. You can see the air ripple when the bullets rush out. And it’s loud—my god is it loud. You’re probably shifting back a good foot when this thing recoils. What were you doing before you got into the trade? I worked at Humpty Dumpty in Brampton, Ont. I was a seasoner for chips. I got hired as a general worker, and I worked my way up to the chip seasoning. It was actually a real cool job. It was night shifts, but I survived.

Favourite TV show: I’ve got two. One that I’ll watch at any point in time is How It’s Made. I think it’s just because I’m mechanically inclined and I like to know how things work. But if I want to decompress, I’ll watch The First 48, or other crime and cold-case shows. Favourite sport: Basketball Favourite food: I could sit and eat beef ribs forever. Favourite beverage: I love drinking tea.

Favourite movie: Get Out. That concept is so left-ﬁeld.

Playing with Point of Use B y Fr ed d ie M o lin a

maller than a briefcase and providing hot water right to the source, point-of-use water heaters are a great solution when space is limited or a customer simply wants hot water on demand. In compact living quarters, such as a kitchenette, in-law suite or half-bathroom, a point-of-use system optimizes the available space. Electric units can be mounted horizontally or vertically, and with extremely high thermal efﬁciencies, these units hold appeal for energy-conscious customers.

SIZING AND INSTALLING Sizing the unit correctly is one of the most important factors for proper installation. Because they’re smaller than standard water heaters, point-of-use water heaters have limited capacity and customer call-backs may occur if the amount the unit delivers is not what the user was expecting. To size a point-of-use water heater, determine the ﬂow rate, or demand, at each ﬁxture, and select the capacity accordingly. While many will choose to install the water heater directly at the sink, the units may also be installed in-line with a larger hot water source to eliminate waits for hot water.

Of course, point-of-use water heaters are not just for small living spaces. They can also be a ﬁt for large homes where a sink or shower may be located far from the central water heater. In a large home, it may take a very long time for the hot water to reach a sink, and may not get there before a customer is done at the tap. It could also be that, by the time the hot water from the primary source reaches the farthest washroom, the water has lost a lot of heat and may be at a lower temperature than desired. These issues can occur when consumers have to choose one temperature on a water heater for all applications in the house. With point-of-use systems, the customer can choose the temperature they want for each speciﬁc use.

Maintaining the Unit Proper maintenance will extend the service life of a point-ofuse water heater, and allow it to perform at a higher quality. Prior to servicing a unit, make sure that you turn off the power supply and drain the water heater beforehand. A critical maintenance element is the annual inspection of the unit’s anode rod. When water is heated, it becomes slightly acidic. The anode rod will attract minerals and protect the inside of the tank from corrosion. To ensure longevity of the tank and prevent it from failing or leaking, replace the anode rod before it is eaten away. Inspecting it at least once a year will help ensure that it is still in good shape.

M e c h a n i c a l

B u s i n e s s

0 6 . 1 7

The surface of the anode rod should appear smooth. If the rod is bumpy, rusty or missing completely, it must be replaced. Certain installations, such as high-ﬂow or recirculation applications, may require more frequent replacements of the rod. Other issues that may affect the anode rod include poor water quality and galvanic corrosion. Not all point-of-use tankless water heaters include anode rods, so inspect and replace only where applicable.

FAST FACTS ABOUT ALT HOTEL ST. JOHN’S

By Denise Deveau

SIZE:

148 rooms St. John’s, N.L.

Open loop sea water geothermal system NUMBER AND SIZE OF WELLS:

One well, 16-inch diameter, 40 feet deep SUPPLY: 240 gallons of sea water per minute to the plate heat exchanger

ALT Hotel St. John’s GEOTHERMAL WITH AN OCEAN VIEW

room with an ocean view can be a great selling feature for any hotel, but the appeal of that ocean doesn’t just end at the window or balcony. It can present some interesting engineering opportunities as well. Nestled next to the Atlantic Ocean, overlooking the harbour in St. John’s, N.L., is one such project where the ocean plays a major mechanical role: the recently constructed ALT Hotel. Opting for a geothermal system to heat and cool the four-storey, 148-room hotel in a location colloquially known as The Rock, the engineering team at Genecor Experts-Conseils had to look for a less traditional way to source the heat energy that would normally come from pipes buried in a geothermal ﬁeld. St. John’s was a rare opportunity for the engineering team to do something completely different, says Gaétan Theriault, projects manager for Genecor in Quebec City. “The hotel is only 75 feet from the harbour, so water is coming in under the hotel every tide. We realized we could use that sea water to handle both heat gain and rejection. So instead of regular geothermal wells we decided to use sea water wells. In this situation it’s impossible to use regular geothermal wells because there is simply too much water.” No strangers to geothermal heating, Groupe Germain, owners of the ALT brand, asked about the possibility of

Keeping up with DHW While the system is responsible for the building’s heating and cooling needs, Theriault says they had to go with domestic hot water heaters for the hot water supply. “We need as much heating of the fresh air intake as possible during the winter months, without worrying about the hot water,” he explains. With no gas services offered in the city, the building is using electric water heaters for the domestic hot water needs.

PROJECT PROFILE

AVOIDING SALT WATER SURPRISES

One of the most important considerations for the project – and not a surprising one – was the issue of corrosion from the sea water. To address this, Genecor had to use all stainless steel components for the pumps, pipes and valves upstream to the heat exchanger. “After that point it’s just carbon steel,” Theriault says. That, of course, came with a cost. He estimates that stainless steel valves are about triple the cost of carbon steel and the pipes were a 15 per cent premium. The heat exchanger itself is titanium at a cost of $30,000, signiﬁcantly more than the typical $12,000 or so price tag.

EACH UNIQUE, IN ITS OWN RIGHT The ALT Hotel St. John’s is not the only geothermal project in the Groupe Germain portfolio. Genecor has also done geothermal installation for the latest Germain properties in Calgary, Toronto and Halifax. “Each comes with its own design needs,” Theriault says. Much of the design decisions are based on a property’s overall heating and cooling requirements, the local terrain and available space for the geothermal wells. At Hotel Le Germain Calgary, a 147-room property with 72,000 sq. ft. of ofﬁce space and 40 condo units, an 80-well, 600-foot-deep closed loop system was placed under the parkade to provide 384 tons of heating and cooling capacity. It handles the heating and cooling for the combined hotel, ofﬁce building and condo property.

Since the complex requires 650 tons of cooling and heating, a 375-ton evaporative water tower is used for additional cooling and boilers provide 5 million BTUH for additional heating during the winter. Overall the property saves about 30 per cent more energy than the reference for this type of building, according to Theriault. The ALT Hotel at Toronto’s Pearson Airport has 153 guest rooms and 15,000 sq. ft. of conference rooms and service areas. The closed loop geothermal system there has 18 wells drilled 500 feet deep for 72 tons of cooling or heating capacity, which handles up to half of the building’s load demand. An 80-ton dry cooler and 380,000 BTUH boilers provide additional cooling and heating.

M e c h a n i c a l

B u s i n e s s

The geothermal ﬁeld is installed under the outside parking lot, using one-and-a-half inch piping into the wells where the heat transfer takes place. Offering 169 guest rooms and 32,000 sq. ft. of conference space, the ALT Hotel at the Halifax International Airport has a geothermal installation that is similar to the Pearson location; the one exception being 745,000 BTUH provided by its boilers for additional heating.

sea water geothermal system, so the engineering firm researched the option. “It turns out there were one or two buildings in the city that had used this design,” Theriault says. The end result was an open loop design, versus the closed loop system that his firm has used on other ALT projects. In the planning stage they realized an entire field wasn’t needed. “We were originally supposed to have three wells but realized we had sufficient capacity to manage all the heat exchange needed with one,” Theriault says. The single 16” diameter, 40-foot-deep well was drilled directly under the parkade ramp at the P1 level, and a 240 gpm pump was installed in a room under the ramp to supply sea water to the plate heat exchanger. The plate heat exchanger allows the heat transfer between salt water on one side to the water going into the chiller and the heating/cooling loop. From there, two pipes run to and from a 130ton water chiller that does the cooling and heating for the property. “If we need to reject heat outside the building for air conditioning, we can do that into the sea water,” Theriault explains. The water chiller has two different heat exchangers inside for running the cold and hot water loops. The fresh air entering into the building (800 cfm) is heated with the geothermal system, as is the snow melting system at the hotel entrance and the parkade ramp. While the system serves most of the property’s heating and cooling needs throughout the year, Genecor also installed a 500 kW electrical boiler to add heating to the loop when needed. The two parkade levels are heated with electrical force flow units. All rooms in the hotel are equipped with twopipe fan coils and a six-way valve. The cold water and hot water networks go to six-way valves that are positioned according to the heating or cooling demand of the room thermostat. DDCs (digital direct controllers) are used to manage all the mechanical equipment and for all rooms at the ground floor level. Guest rooms have standalone temperature control systems controlled by thermostats, as the fan coil units are not linked to the DDC controller. Theriault says it took about six months to install all the mechanical and electrical equipment for the project, with an additional four weeks added for testing and start up. “We’ve been involved in many geothermal projects, but this was definitely the first time we did anything with sea water. It was a great learning experience.”

HIGH-PERFORMANCE HVAC

Gord Cooke is a professional engineer who has spent 20 years helping builders and HVAC contractors implement innovative technologies into highperformance homes. He has particular expertise in IAQ and airﬂow management in houses, and can be contacted at gcooke@ airsolutions.ca.

Brushing Up on

SIZING Calculations O

ne of my colleagues was recently shopping around for a replacement furnace for his older home. He had a local HVAC contractor come to his house to quote the job.

BuildingTRUST As I have written before, I am not worried about the impact that grossly oversized systems have on comfort and performance. But I am worried that this sort of thing hurts the integrity and credibility of the HVAC industry speciﬁcally, and the building industry as a whole. We have enough reality show professionals telling homeowners that we don’t know what we as an industry are doing, or worse yet, that we aren’t to be trusted. And we also don’t do ourselves any favours by immediately calling into question the integrity of our colleagues in the industry when we visit a new home to size an air conditioner.

After walking around with a tape measure and calculator for five minutes, the salesman announced that the house would require at least a 60,000 BTUH unit. He acknowledged that a 50,000 BTUH unit like the one that was being replaced would probably do the trick, but seeing as the contractor’s brand of choice only came only in 40, 60 or 80,000 increments, he defaulted up to 60,000 BTUH model. My colleague raised concerns about this, as his old furnace always seemed to be short-cycling. The salesman insisted that my colleague would be “rolling the dice” going with a smaller unit, and reminded him that he’d been sizing and selling furnaces this way for almost 20 years. Now, the house in question was indeed quite old, but had been renovated by my colleague with new low-E argon gas windows, additional insulation in the attic and basement, and significant other efforts that cut the tested air leakage rate in half. However, none of these updates made their way into the salesman’s calculations, nor did the homeowner’s observation that his existing furnace, which was both smaller and considerably less efficient than the proposed unit, already seemed to be oversized.

Rule-of-thumb approaches have no place in equipment sizing, or in the HVAC industry at all for that matter. The square-footagebased approach has only ever resulted in an appropriate size recommendation by dumb luck, and is now inexcusable given our current level of knowledge and the technology available to us. HVAC modiﬁcations impact the whole house system and must consider a great many more variables than just square footage or bedroom counts. We need to consider the many factors that determine proper sizing; not just look at one piece of the puzzle.

A Troubling TREND In recent years, I’ve noticed this troubling trend emerge in new constructions as well – generally when homeowners call up an HVAC contractor to have an air conditioner installed. Some contractors show up and inform the homeowner that their brand-new home has been ﬁtted with a furnace and ductwork that is too small. You can imagine how frustrated a builder and the original HVAC contractor would be when a disgruntled homeowner calls to complain. After all, the builder employed a qualiﬁed HVAC designer, who used a complete set of plans and

speciﬁcations and the latest CAN/CSA F280-12 Standard Determining the Required Capacity of Residential Space Heating and Cooling Appliances. Then the builder submitted the plans for permit and had a qualiﬁed HVAC installer select and install the equipment.

Making the Right CALCULATIONS

All that work, just to be totally discredited in a matter of minutes by someone using incomplete information and 20-year-old sizing standards.

The compelling code changes, plus the ﬁne tuning of the F280 sizing standard, have meant that the design heat loss of homes across Canada has dropped in half compared to homes built as recently as 2005. The design cooling load has dropped by at least 30 per cent, primarily because of better window selections. So let’s ensure we have updated or recalibrated that old rule-of-thumb with the following ideas:

I know of at least four builders who have fallen victim to this frustration. All of them have voluntarily chosen to build Energy Star-qualified homes that are 20 per cent more energy efficient than base code levels and employ third-party evaluators to confirm air tightness, proper window coatings and insulation levels.

1. Purchase and use updated software that is F280-12 compliant, and populate it with modern insulation levels and more realistic air tightness levels.

In all four cases, the design heat loss approved by building permit was under 40,000 BTUH, and heat gains ranged from 2 to 2.5 tons. But when aftermarket contractors assessed the homes, they recommended furnaces ranging in size from 75,000 to 80,000 BTUH and 3- to 3.5-ton air conditioners.

Working Together

As more and more contractors educate themselves and update their practices, this problem should take care of itself. I think that we as an industry—particularly contractors, salespeople and designers—need to recalibrate the way we think about equipment sizing. It’s time we all got on the same page so that we’re not contradicting one another, discrediting each other’s work and misleading our clients. M e c h a n i c a l

If the homeowner can’t get the design calculations, have them pull out the Schedule A from their original purchase agreement. It will show the insulation levels and window types installed in the home. At the very least, educate your sales staff on how better envelope characteristics can impact furnace sizing.

4. Invest in some simple

The bottom line is that the science has come a long way in recent years, and new measurement devices and sizing software are widely available. There is no reason why HVAC contractors should be arriving at widely different equipment size selections and making homeowners question the competency of their builders, previous contractors or our industry as a whole.

2. Remember that, in most municipalities, if you’re dealing with a house built in the past ﬁve to 10 years it is likely that the builder will have a heat loss/gain study available upon request. You should take advantage of this to improve service and reduce your risk.

measurement tools and use them to help homeowners make better choices. For example: • For about $500 you can buy a simple handheld device that will detect low-E coatings in windows and indicate their solar heat gain coefficient. • If you have concerns about the size of the ductwork, start using your digital pressure gauge to measure the static pressure across the air handler. • If you don’t think there is enough airflow capacity in the air handler to deliver the required cooling, measure the flow at the furnace using either a simple temperature rise method or purchase an airflow measuring device. • Start selling “smart” thermostats on all your service calls, so when it comes time to add or replace a system you have accurate run time data from the existing equipment.

PLUMBING

PICKING THE PROPER PUMP By Ada m F r e i l l When it comes to moving unwanted water out or away from buildings, there are several kinds of pumps to choose from, depending on the type of water and the size of any solids that may be present in it. While some models can be used in multiple applications, each pump is designed with a particular purpose and application in mind, so it is always advisable to review the manufacturer’s literature before swapping out a pump. “It is important not to apply a pump in an application where there are solids-handling requirements that exceed the pump’s capabilities,” explains Denton Gaiser of Canature WaterGroup. “In most cases, an effluent or sewage pump can be used in place of a sump pump,” adds Franklin Electric/Little Giant’s Randy Tucker. “However, a sump pump cannot be used in effluent applications requiring the capability of pumping 3/4” solids, or for sewage applications requiring the capability of pumping two-inch solids.” When it comes to pumps designed with solid waste in mind, such as the discharge from a toilet, a sewage pump would be an appropriate choice where piping allows for the passage of two-inch solids. Macerating and grinding pumps may be a consideration when appropriately sized sanitary drainage lines do not exist, or would be costly to install. These pumps make use of smaller-diameter pipe for waste removal. This, says Stuart Saville of Zoeller, may occur when “the fixture is located below, or in an inconvenient location away from, the sanitary pipe of the home or the business.” When a building has undergone a change in use, perhaps from a commercial warehouse to a residential complex, Saville adds that a grinder pump can help resolve drain-side dilemmas when the structure’s plumbing piping cannot be upgraded. Both macerating and grinder pumps mechanically reduce raw sewage particle sizes, creating a slurry that can be pumped through piping less than 2” in diameter, explains Michael Carr of Saniflo. One of the main differences, he says, is that a macerating unit will reduce soft sewage particles, while grinders will reduce both sewage and organic materials.

PUMPS AND APPLICATIONS SUMP PUMP: Used for removing water from such areas as basements, French drains and water collection systems. In a residence, it is used to pump water from a collection pit to protect structures below ground from ﬂooding.

EFFLUENT PUMP: These pumps can be used in a septic system, or to transfer industrial waste water to or from holding tanks and ponds.

M e c h a n i c a l

B u s i n e s s

SEWAGE PUMP: Designed with larger ﬂow capacities than sump or efﬂuent pumps, most residential models have the capability of 2” solids handling.

MACERATING PUMP: These are used to pump a slurry of raw sewage through smalldiameter plumbing lines for transfer out via a building’s sanitary drainage system.

GRINDER PUMP: These are used to create and pump a slurry of raw sewage to the sanitary drainage system via small-diameter pipe. Similar to macerating pumps, models are generally capable of handling more demanding applications.

Heating Up C

ontractors often come across the challenge of having to heat a small ﬂoor space. The decision of which technology to use generally comes down to such factors as up-front and operational costs, location of the space in question and existing systems.

ELECTRIC HEATING

MATS Electric heating mats are a very common choice for heating a smaller area because they are both versatile and easy to install. Wally Lo, product manager for Pentair/Nuheat, says that mats are preferable when extending pipes from existing heating systems is not an option. “They’re great for renovation projects.”

The three most common options for heating small zones are electric heating mats, the extension of an existing hydronic system, or tapping into a combi system or domestic hot water system. Each has its advantages and challenges, depending on the project. The key question you need to ask a customer is a simple one, says John Goshulak, vicepresident of sales and marketing for WeilMcLain Canada. “Are you trying to warm the room, or just the ﬂoor?” Once you answer that, decisions become easier.

SM AL L SPAC E S

Are you trying to warm the room, or just the floor?

Tracy Hall, national sales manager at SunTouch, a Watts Water Technology Company, says mats make the most sense for areas smaller than 1,200 sq. ft., with master bathroom floors being a prime target. “Contractors only need to cover the walking area of the floor,” says Hall. “There is no need to go underneath cabinets or toilets.” Mats come in three different heat outputs: 10, 12 and 15 watts per sq. ft. The standard for doing a bathroom floor over a plywood subfloor is 12 watts. A standard mat will work well in rooms with square corners. When heating a floor with many angles, or curved wall areas over 100 sq. ft., a custom mat makes more sense, Hall notes. Custom mats may add to the overall costs of materials, but that is easily made up for in labour savings, Lo explains. They’re also simple to install, since they can be connected to standard electrical systems. All that is required are plastic guides around the room perimeter and manually running the cable system back and forth. However, the job can be made simpler by using prebuilt systems.

Watts

When using mats over a concrete slab, Hall suggests tightening the spacing of the wiring to create higher heat output to combat the heat drain of the concrete. Another option is putting an insulation barrier over the slab, although that will raise the height of the ﬂoor.

Leaders in Magnetic Separation Small and often microscopic magnetic particles, called magnetite, form when iron or steel corrodes. Highly abrasive, the extremely fine sediment is difficult to remove by traditional means. SEP4 ®, DISCALDIRTMAG ® & DIRTMAG ® separators capture magnetite with a concentrated magnetic field. Dirt and magnetite is quickly flushed out of the drain valve when the magnet is removed while the system is operating. DISCALDIRTMAG ® combination air & dirt separator removes micro-bubbles, dirt and magnetite, plus the SEP4 ® provides hydraulic separation. All having 2½ times the magnetite removal performance of standard separators, delivering up to 100% elimination efficiency.

TAPPING INTO HOT WATER Under the right circumstances, a combi hot water tank system, with an internal heat exchanger certified for combination use, can be a cost-effective way to heat floor surfaces, says Sean Giberson, Canadian sales manager of residential products for Taco Comfort Solutions. These are often used in new construction sites, where floor heating is desired in only some rooms of the home.

Runtal

“Retroﬁts can be much trickier as the ﬂoor surface is raised when the tubing is installed on top of the existing surface and then is over-poured with another lightweight concrete material,” he says.

EXTENDING THE HYDRONICS W

hile it makes sense to extend an existing radiant-based heating system to service a small zone within a home, this type of solution may create some engineering challenges. “If I were to say use hydronics over electric, the deciding factor would be proximity to the existing mechanical equipment,” Goshaluk says. “The small zone has to be reachable from the hydronic system. If a bathroom is next to a radiant heating system in the basement or accessible through a closet or chaseway, then it’s the right choice. If it’s a foyer two floors away, I wouldn’t necessarily do it that way.” In terms of temperature parameters, 100°F to 110°F is a good operating range for floor heating, he adds. “Anything over that is too hot.” Getting to the right temperatures could involve installing mixing valves. Tubing size also affects performance. “If you try to push water through a 1/2” tube, it will only go so far,” Goshulak says. Longer distances require bigger tubes (e.g., 3/4”) and a bigger pump to ensure proper flow rates in the loop. Other equipment components should be looked at as well, he says. “Even if it’s a small load, a professional needs to look at what’s required and the potential impact on existing equipment to make sure it doesn’t adversely affect something else.” There can also be issues with short cycling, says Paul McDonald, general manager for Laars Heating Systems, a division of Bradford White. “If you have a boiler capable of satisfying very large output and you add a small capacity zone, it will turn on way too much output for that zone, leading to short cycling,” he says. A buffer tank can help combat short cycling, however.

On upper floors, additional floor tubing either comes from underneath the subfloor (i.e., a stapleup radiant floor heating system); or is added on top of the finished flooring and over-poured with lightweight concrete. Another alternative is radiant panels that sandwich the tubing inside premanufactured panelling. Every loop should remain at 250 feet or under when using 1/2” tubing, Giberson adds. “Always consult the radiant tubing manufacturer about recommended tubing sizes and lengths per loop,” he advises. “If adding onto an existing system, you will likely need more loops at the manifold location. Also bear in mind that as soon as you add loads, you may have to resize equipment such as the pump, the heat source itself and expansion tanks.” When it comes to combi systems, consider whether you are using an open loop potable system or a water heater with an isolation heat exchanger inside the tank. “The industry is much more on the side of having separation in a system, so potable water doesn’t stagnate during the off season,” Giberson says. Where potable water is being used, components must be non-ferrous, he adds. A closed loop heating system with an isolated heat exchanger can use cast iron parts at less cost.

TOOL TIP

Getting a Read on Multimeters

ny contractor looking to install, maintain and repair electrical components in a mechanical system — sensors and motors, for example — needs a professional-grade multimeter. These handy devices are great for testing panels and checking current, amps, resistance and capacitance. But not all multimeters work in the same way, or offer the same array of features. When shopping for a multimeter, look for one that will handle the full voltage range of the equipment you work on. Also consider the IP (Ingress Protection) rating of the device. An IP 54 meter is designed to stand up well in dusty or high-moisture conditions.

saniflo.ca VIEGA MEGAPRESS® SYSTEM BRINGS PRESS TECHNOLOGY TO BLACK IRON PIPE The Viega MegaPress and MegaPressG systems for installing schedule 5 to schedule 40 black iron pipe in sizes ½” to 2” make secure water- and air-tight connections in less than seven seconds. The Viega MegaPress system is ideal for hydronic heat, chilled water, compressed air, ﬁre sprinkler systems, low pressure steam and vacuum lines. Viega MegaPressG ﬁttings are designed for use in fuel oil and natural gas applications. Viega. Connected in quality.

viega.us

CAT ratings (generally CAT III and CAT IV for the mechanical sector) refer to a multimeter’s ability to resist a voltage spike. Large LCD screens with good contrast can make working in low light a little easier, and some units afford the ability to work hands-free, thanks to belt clips and mounting magnets.

AVERAGING VS. TRMS While both averaging meters and true root mean square (TRMS) meters will accurately measure sinusoidal AC waveforms, TRMS meters can also read non-sinusoidal AC waveforms, increasing the accuracy of the readout when working on HVAC equipment and variable-speed drives.
