The top responses for what was stopping someone from pursuing a career within this sector were “I had other passions I wanted to pursue for a career,” “I couldn’t afford a trade/vocational school to learn a skilled trade,” and “there isn’t enough career growth opportunity.”Asmuchas the industry has been working hard to fight the persistent stigma that has been associated with the trades, there was still 13 per cent of respondents that said they weren’t pursuing a career in the skilled trades due to the unfavourable stigma. And even more shockingly, 11 per cent said their family discouraged this career path.

to the Canadian government, a record 700,000 skilled trades workers are expected to retire between 2019 and 2028. And yet, there still aren’t enough people looking at actually pursuing a career in the skilled trades.

The 2022 Canadian Hydronics Conference is fast approaching and ready to provide the hydronics industry with a jam-packed two-day conference. Presented by the Canadian Hydronics Council (CHC), this year’s conference will take place at the World Trade Center Prairieland Park in Saskatoon, Saskatchewan, from Sept. 27 to 28.

Education and innovation: key topics at hydronics conference

Both days of the conference will kick off with registration and an open show floor at 7 a.m. A jam-packed schedule of educational seminars is available and will be covering topics such as “Net-Zero and Electrification” presented by Robert Bean (Indoor Climate Consultants), “Smart Technologies in Hydronics” presented by Watts Water Technologies, “Snowmelt Systems” presented by Jean-Claude Remy (Uponor Ltd), “Chemical and Non-Chemical Water Treatment Options” presented by

Let’s do our best to find and correct these cross-connections before the damage is done,” said Danny Wilson, WCSAWWA CCC education committee member.

The Western Canada Section AWWA Cross Connection Control Committee (WCSAWWA) has selected the winner of its “Bad and Ugly” cross-connection photo contest. The winning photo was submitted by Stan McCrimmon, a backflow tester plumber who was working for Gateway Mechanical in Alberta at the time of the photo.

McCrimmon, a red seal plumber journeyman, has been backflow testing since 2018 and is currently working on receiving his hydronic designer certification. McCrimmon has his Class A gas fitter and medical gas certification, and has served as a member of the Alberta Provincial Apprenticeship Committee for six years.

Changes have been made to Alberta’s prompt payment legislation. As of Aug. 29, Bill 37, the Builder’s Lien (Prompt Payment) Amendment Act, 2020, will set a 28-day timeline for project owners to pay invoices to general contractors and a seven-day timeline for contractors to pay subcontractors after receiving payment.

The new act applies to all private construction contracts in Alberta created on or after Aug. 29. Current contracts extending past two years must comply with the new rules by Aug. 29, 2024.

“Albertans in the construction industry have advocated for prompt payment legislation for nearly 10 years, so I am excited to celebrate this important milestone,” said Nate Glubish, minister

of service Alberta. “I am proud of the work that Alberta’s government did. Collaborating over the last three years with construction industry members to develop and pass legislation that will protect jobs and unlock cash flow in this multibilliondollar industry that employs hundreds of thousands of Albertans.”

Milligan also raised some concerns stating, “I do not think Victoria has a comprehensive plan for the roll-out of this program, so I don’t know exactly how it will affect the trades. Though I assume, it will require the trades to become better educated. Having said that, Victoria has always had a strong heat pump market. Fortunately, we have been teaching our air-to-water heat pump course for the last nine months as it is mandatory for any installation in the city of Vancouver now.”

We are especially concerned with training and awareness with retrofits and building envelopes. Building envelope and mechanical ventilation must always be uttered in the same breath. Unintended consequences on the part of renovators in terms of indoor air quality and human health could be significant,” said Hughes.

Both Hughes and Milligan stated that both associations were not consulted with this decision. However, Hughes adds that, “It’s important to consult industry when determining a timeline. There are far too many moving points that need to be considered if the city wants to have a successful program that performs as everyone would like.”

Historically the rural home had to rely on wood, coal/pellet, propane, or electricity to power their home comfort heating appliance. For those of us with snow on the roof (grey hairs for the young ones), we have lived through all of them. Each one of them had claims of being the best source for the long haul. But none of them are future-proof.

So, what exactly does it mean to provide future-proof products? I guess the best way to explain it would be to look at it in reverse. What is not future-proof?

Once it was in his hands, McCreadie was hooked on press fittings for HVAC/R applications.

n HVAC Fittings

18 Plumbing & HVAC – September 2022 www.plumbingandhvac.ca

“Press fittings have gained wide popularity in both the plumbing and hydronic trades. They require significantly less time and skill compared to soldering, brazing, or welding,” reports Caleffi. “Although press fittings are more expensive than standard copper tube fittings, the time savings associated with their use typically counteract their higher cost”

Press fittings in HVAC/R applications

There are many ways to join piping to achieve leakage-free joints and still be able to handle high temperatures and pressures. Theclassic methods are often considered welding, soldering, or threading, but now there are products in the market that will offer a quick solution such as press fittings, according to Caleffi’s January 2020 edition of idronics

www.plumbingandhvac.ca September 2022 – Plumbing & HVAC 19

There is something to be said regarding balancing the new and old methods of connecting HVAC/R piping. Gary McCreadie, president of McCreadie HVAC and Refrigeration Services Inc and the creator of HVAC Know It All, has been using press fittings on his job sites for around a year-and-a-half to two years. “I didn’t really know much about the technology beforehand because I hadneverusedit.I’ve neverhelditinmyhand.I’veneverseen it on a job site, and then when I got the tool in my hand and opened the box, I’m like, “man, this is impressive.”” explains McCreadie.

I think it’s important to know both because you’re going to be putting applications and situations where you might need to braze. But then if you dismiss press, you might be put in a situation where the engineer specs you to use press. If you dismissed it for so long, and now, you’re not in the right headspace to use it. So, it’s always important to know both for sure,” explains McCreadie.

Health concerns

The cost of tooling is one reason that press fittings haven’t taken over more of the market share. “A contractor would need to know how to use a press tool and jaws designed specifically for the press fitting to ensure a successful crimp during an installation,” explains Martin. “When compared to the trade skills that are required for brazing or soldering, pressing can be learned rather quickly!”Oftentimes, work vehicles can have somewhere in the ballpark of $20,000 worth of tools, so trying to get a contractor to buy another tool for around $4,000 might be a difficult discussion they’d have to have with their significant other.

As mentioned prior, there are instances on the job site where brazing, soldering or another type of pipe joining method might be the best option. But there are applications where

There is no need to get fire permits with press fittings as there is no open flame.

In addition, by using press fittings, there are fewer health concerns for the user. When it comes to brazing, there is the chance of ingesting burning oil or insulation because the contractor is in such close proximity to the material. Using something, like a press fitting, takes away the whole health concern because there isn’t any smoke to be breathed in, explained McCreadie. : Fittings

There are still plenty of reasons why a contractor would choose to go with a press fitting. The most mentioned benefit is the increased speed of installation, “The more joints that you have, the more press fittings become a bigger solution for you. You’ll kind of lean towards that, especially with a commercial ductless application where there’s just lots of joints,” explains Schubert. “There are also other benefits. It’s safer and more repeatable. Those kinds of things that press fittings give you over traditional brazing.”According to Martin, press system installation takes as little as 30 seconds to create a permanent, leak-free seal, and requires as much as 95 per cent less time to install than with traditional soldering or brazing.

Increased speed of install is just one of the benefits associated with press fittings.

Pros and cons

press might be the best fit. One such reason is due to fire permits. “We were in a building in downtown Toronto at a Cadbury chocolate factory, which smelt delicious," explained McCreadie. “It was an old factory, and they had a fire watch time of four hours after the flame went out. So basically, after the flame went out, you had to stand there and wait for four hours before the security and sign-off. In an application like that, where you need a fire watch and fire permits to bypass smoke alarms, you get rid of all of that with a press system. It’s completely gone because there’s no worrying about it.”

Heat Pumps are not boilers, and we can’t treat hydronic heat pumps as boilers. As we see the electrification Act build momentum across Canada, more and more manufacturers are bringing new heat pump technology to Canada. This means that we are going to see a whole new industry open up in front of us as hydronic heat pumps begin to offset the traditional natural gas and propane boiler business, just as these technologies did for coal and oil before them.

No secrets here, the plot twist is in the headline.

n Hydronics

Hydronic heat pumps could offset natural gas or propane boilers as industry looks to electrification.

The principal purpose of this article is to talk about some of the differences and challenges we will face as we adopt hydronic heat pumps, specifically water-to-water and air-to-water equipment. We need to be fully aware of the ramifications of what will happen when we don’t take the time to get properly educated on this evolving technology. It is the old saying, “You do not know, what you do not know.” Which means, when you do go to hook up your first hydronic heat pump piped up like a standard boiler, you will not know at first glance that A) it is wrong and B) what is going to happen if it is wrong.

There are currently two common types of hydronic heat pumps in Ontario. They are water-to-water geothermal units and airto-water heat pumps. Both of these units generally don’t like to see water temperatures above 120 F. A few will read that last sentence and say not true, and they are somewhat right. A vapour injected water-to-water, or airto-water heat pump can, in theory, produce higher leaving water temperatures but at the sacrifice of efficiency and capacity.

Continued on page “27”

Moment in the spotlight

On an air-to-water, the higher the outlet water temperature is from the air temperature, the lower the overall performance of the unit and in many cases the heating and cooling capacity. The same is true for a geothermal hydronic heat pump, only it is the ground loop temperature versus the air temperature that will determine overall performance and capacity. A geothermal hydronic heat pump has a higher efficiency, but it has some limitations in terms of where it can be installed due to the requirement for a ground loop.To illustrate this point, the table adjacent is from the Advantage five-ton vapor injected variable speed air-to-water heat pump. As you can see, this unit can easily achieve 130 F

A technician with the Hayter Group in Alvinston, Ont, installed these two water-to-water units.

If you do this on a hydronic heat pump, you are putting the refrigerant circuit under significant stress. An R410 compressor circuit running at 140 F water can result in

All of the statements I just made also apply to a water-to-water unit only with even higher COP numbers because the ground loop temperature is stable all winter long, whereas the outdoor temperature is not.

We need to be fully aware of the ramifications of what will happen when we don’t take the time to get properly educated on this evolving technology.

This unit can easily achieve 130 F water and can run down to -13 F

So, on the table above at 14 F for every unit of electricity I buy, my equipment has a COP of 2.4 or 240 per cent efficient at 131 F water.

do not even notice. The boiler still condenses, and you have no penalty. But on an air-towater heat pump, some of our habits are significantly hampering the overall return on investment of the heat pump. Even more impressive if we were to use a low temperature convector, we can heat the space using 100 F water. For example, a Jaga low H20 product at 100 F water would produce 9,682 BTU/h. That is a staggering amount of energy for very low water temperatures. We have now taken the same piece of equipment and taken the COP up to 3.4.

water and can run down to -13 F. But should we run the equipment so hot? For those not familiar with COP, it is the coefficient of performance. For every unit of electricity you purchase, you will get X amount back for free.

That is a hefty bump just by working from a design versus winging it. On a boiler, many

Do we actually need 130 F water? A properly designed radiant floor system will easily heat a home with 100 F water. If we look at the exact same conditions, 14 F outside temperature, and use 113 F water, we end up with a COP of 2.8 or 280 per cent efficient.

With a heat pump, it is very important that we design around the correct water temperatures. If you don’t, it won’t immediately result in a callback, but it will definitely cause performance, comfort, and cost of operation issues. The other thing I caution you about is using this product on copper fin tube rads. I have seen in the past, where boilers are installed, and afterwards, when it can’t heat with 120 F water, the end user or the service technician cranks the water temperature up to 150 F or 160 F. This is a fix that eats into

the cost of operation and generally goes unnoticed by the homeowner.

A geothermal hydronic heat pump is superior because regardless of outdoor temperature, you know what your COP will be and what your capacity will be because with a properly sized earth-loop, the ground temperature is stable. In some places, geothermal makes more sense than air-towater and vice versa. Can you install a ground loop being the big driving question.

to-water unit. Your ground loop temperature will dictate your capacity.

You want to also be aware of when you pipe a hydronic heat pump; what are the actual required flow rates? On a boiler, we are used to a 20 F Delta T and one GPM. This will equate to 10,000 BTUs. On a hydronic heat

catastrophic equipment failure. Looking at the table below in heating mode, you can see that there is a solid red line, and we want you to stay inside of that envelope which is max of 130 F but again, understand what that does to your overall COP by running a system hotter than is needed. At 140 F, you are creeping outside of the safety buffer.

Not only do we need to be aware of the need for properly sized piping based on the equipment type, but we also need to be very aware of the requirement for a buffer tank. On a geothermal water-to-water heat pump, we require that buffer tank to ensure the equipment gets a minimum run time of 10 to 15 minutes to maximize its performance. Some water-to-water equipment is fully modulating, and some utilize a two-speed compressor. These heat pumps need a buffer so that when the load does not perfectly match the equipment output, we do.

You want to stay inside of the envelope.

Continued from page “27”

Know your requirements

Your design temperature will dictate the capacity of the equipment as will your leaving load temperature. With an air-to-water heat pump, your outdoor design temperature will dictate your overall capacity and with a water-

pump, depending on the design, that may not be the situation. Take for example a waterto-water geothermal heat pump. Some of this equipment requires three GPM per ton, which means we are not operating on a 20 F Delta T but a 5 F to 8 F Delta T. This is why on a five-ton geothermal heat pump you will see the manufacturer calling for one and a 1/4inch or one and a 1/2-inch pipe where you would be used to using much smaller piping if this were a boiler.

Determining capacity

This passive house building, located in Vancouver, was heated and cooled using water-to-water heat pumps with fourpipe coils for terminal units and six-way valves that modulate.

If you do not pipe the equipment with properly sized piping and a properly sized buffer tank, the end results can be quite catastrophic. The good news is that there are talented designers and suppliers with decades of experience that can help you navigate the exciting new world of air-to-water, and the not-so-new world of geothermal water-towater equipment. :

Natural disasters can happen at any time and to anyone or thing. Recent examples like the flooding in both the South-African province of KwaZulu-Natal and British Columbia, and the forest fires seen in Los Angeles have, once again, reiterated the importance of being prepared for when things simply go wrong. Between 2000 and 2019, there has been an average of 361 disasters annually. In 2019, approximately 91 million people worldwide were affected by natural disasters. It is also reported that four billion people experience severe water scarcity during at least one month of the year, according to a study done by Science.org.

Rainwater harvesting

Collected rainwater can be used for potable and non-potable uses. Rainwater can also be used to supplement a wastewater treatment system, such as a grey water or as a black water reuse system. As Van Giesen explains, “Waste water can come from showers, toilets, washing machines, and we’re beginning to see how we can tap into recycling wastewater and using it as an additional water source for nonpotableRainwaterapplications."harvesting systems are more commonly seen on residential projects but have been in increasing demand in the commercial sector. “The cost of these systems depends on the storage volume and the system’s daily processing capacity. It also depends on how much of the roof’s surface will be directing water to the storage tank,” said Van Giesen. Depending on the project, a rainwater harvesting system could have water storage tanks placed above or below ground.

The collected rainwater can be used yearround or seasonally.

they leak so much, every time there’s rain, freshwater gets into the sewage treatment system.”When it comes to protecting your plumbing system in an emergency, there are many things homeowners and business owners should know. An essential first step is “ensuring your family, tenants, or employees know how or where to locate the gas, electric, and water shutdown controls and how to deactivate them in the event of an emergency,” said Dunbar.

Another critical step in preparing for an emergency is ensuring a home or office has a supply of safe water. This can be accomplished by incorporating a rainwater harvesting system into the home or building design as it allows for the collection of water to be used in the event of an emergency.

Canada still has some work to be done regarding flood preparedness. This is evident inarecentreportconductedbythe Universityof Waterloo titled “Climate Change and the Preparedness of the 16 Major Canadian Cities to Limit Flood Risk”

This report showed the findings showed that the average grade for Canadian cities was a C-plus, which was the same score back in the 2015 edition. One of the ways the City of Toronto has prepared its residents is through its “Basement Flooding Protection Subsidy Program” Owners of a singlefamily, duplex, or triplex residential home could be eligible for a subsidy of up to $3,400 per property to install flood protection devices. Eligible work through the program includes installing a backwater valve, a sump pump, severance and capping of a home’s storm sewer or external weeping tile connection. :

Rainwater harvesting can even use waste water.

Arguably one of the most critical prevention methods, backflow prevention is vital to providing safe and clean water. Backflow can occur in various scenarios, whether it’s a broken washing machine hose, floods, or sudden changes in water pressure.

Carbon dioxide refrigeration will play a key role in decarbonization, especially within hydronics.

Contrary to how it sounds, when carbon dioxide (CO2) is used as a refrigerant, this doesn’t mean that it’s being used as the fuel source, “I didn’t think that was something we actually needed to specify until we had a customer ask, “Wait, so I’m burning the CO2?” joked Andrew Macaluso, product

While it’s difficult to compare natural refrigerants based on its environmental impact, the decarbonization trend within the industry has been a driving force for the adoption of R744 refrigerant. Each type of natural refrigerant, whether it may be ammonia, CO2, or propane, has its place for when it should be used for a project. Nowadays, CO2 lends itself well to domestic hot water production and supermarket applications, while refrigerants like ammonia work well in industrial applications. But because of safety concerns, it isn’t as commonplace within commercial or residential applications, explains Macaluso and Cummings.

and more solutions will be offered. “I think it’s the best solution because its global warming potential is so low and that has become a hot topic for our industry anyway. It is nonflammable, plus, it has a high heat transfer coefficient,” said Rana. This also means that CO2 performs quite well in Canada’s cold weather climate. “It’s kind of what separates the CO2 products from most of the typical refrigerants because HFCs have already seen a lot of adoption in warmer climates,” explains Macaluso and Cummings. “CO2 will work well in a warm climate, but it’s one of the only ones that will also work in a cold climate and that’s really where it differentiates itself. I would say that generally speaking, it’s going to work better than what’s available on the market today for cold climates.”

there are other safety concerns to keep in mind, which include asphyxiation, trapped liquid, dry ice, and freeze burns, explains Patenaude. Keeping up to date on the latest training will help ensure that no one gets injured on the job.

There may be many individuals that will turn to carbon dioxide for their refrigeration solutions solely due to its energy savings, but as the technology becomes more commonplace, more people will likely turn to it for other reasons. As Macaluso and Cummings put it, “I think what we’re going to see is people looking at them for other reasons… maybe it’s just an energy cost savings or maybe beyond that. They’re looking to not only electrify but shift their electrical load and storing energy in water versus storing it in a battery gives them a lot more flexibility in how they do that. I think that as this starts to become more and more commonplace, you’ll see more people looking at it for a variety of reasons beyond just, ‘hey, I want to be the green guy on the block’”This brings something important to light regarding carbon dioxide systems— everything is electronic, reports Patenaude. There are no mechanical valves other than shut-off valves. Since it is operated at such a high pressure and it is an extremely reactive refrigerant to pressure and temperature changes, electronics are the only type of product that can react quickly enough to changes within the system.

In addition to high-pressure concerns,

CO2 as a refrigerant is extremely reactive to pressure and temperature changes, and as such, requires electrics to react to these changes.

“With time I think natural refrigerants, like carbon dioxide, have a good future. We expect more and more innovation or product range should be available in the heat pump format so that we can even work in our typical commercial and residential application where heat pumps have a great fit,” explains Rana.

When asked what advice he’d give to contractors working with CO2 systems, Patenaude stated that he’s been giving the same advice since he started working with CO2 back in 2014, which was to start learning now. “It is never going to go away, and it will become a larger part of your daily life sooner than you think. One of the things about CO2, which is also a concern, is the fact it’s electronics based—everything is controlled by electronics. No longer can a good refrigeration mechanic get away with doing a good job because he’s not that

As more products are available in the market, this will help drive adoption and drive down the price, “I’m looking at my whiteboard right now and you know, I’ve got four different consulting engineering firms working with us already on heat pumps for CO2 for various reasons (water heaters, air space, light industrial) because of new compression technology that Emerson has developed,” explains Patenaude. “It’s not out yet, it’s still in the development phase. But those are the things that are going to move the mark towards more CO2 adoption, as OEMs continue to design and refine and improve efficiencies and take cost out and simplify architectures. That’s going to drive adoption and drive down the price.” : Refrigeration

The lab has specialized equipment like a guarded hot box — a cube with an internal chamber that’s wired with sensors. Using data from the box, the team of researchers will be able to calculate a wall’s ability to resist the transfer of heat. A pressurized spray rack will also be used to assess the air and water tightness of the same wall samples.

She notes that when improvements are made to the energy efficiency of the living space, its not something that can be easily seen. As such, there needs to be incentives to encourage homeowners to make retrofits. “When most homes are built to last only 60 to 70 years, we’re kind of pushing that with a lot of them now,” explains Cruickshank.

The SFA Group released its flagship product, the Sanibroyeur, back in 1958. Since then, they have designed and produced products within several industries, including water treatment equipment, pumps and pump stations for industrial projects, pumps and sanitary macerators for home use, and equipment for showers, whirlpool bathtubs, and spas. “Saniflo Canada holds corporate social responsibility as one of our top priorities, aligning our brand vision with developing healthy communities,” said Warren. “Whether in our dealings with our distributors or with our end customers, we establish a relationship of trust that has been binding our brand since 1958.” :

Not only did they donate the product, but they also funded the installation and hired

While the company has a lot of initiatives to be proud of, the company’s biggest accomplishment to date has been the evolution of its team and brand, “I take great pride in that. From being known as just a basement, bathroom, and pump company to who we are today, it’s truly amazing. Honestly, by focusing on who we are, what we do, and how we provide an everyday pump solution to all the markets in the plumbing industry,” said Warren.

In addition to donations, Saniflo Canada co-sponsors a charity golf tournament every two years. The Canadian Mental Health Association (CMHA) Champlain East’s Subway tournament raises money to support mental health promotion initiatives

Looking to the future

A brief history

Like several other companies in the industry, Saniflo has vowed to do its part in helping the people of Ukraine. The company was recently made aware of a family in Saskatchewan who was experiencing firsthand the effects of the war. Yana and Jeff Zhdanova were able to bring two family members from Ukraine to Canada. With the expected arrival from Poland, the family had to start preparing accommodations.TheZhdanovafamily’s current home is a

rented ranch home on an acreage with one bathroom. Yana’s mother and grandmother would take up the basement, but the basement allowed for enough space for an additional bathroom. “We decided to offer support in any capacity we could. It’s of the utmost importance to Saniflo that we give back to our communities, especially during this war, so that Ukraine and Canada can continue to build trust in our brand,” said Warren. As such, Saniflo donated one of its Sanicompact, which is a toilet bowl and a macerator in a single fixture.

Recently, they were even recognized with platinum status by the Green Business Bureau. “Our commitment to going green is a powerful influence on our business — from product development to how we conserve water and reduce the wasting of resources. All contribute to the success of our business,” explains Phil Warren, managing director for Saniflo Canada.

Another initiative that Saniflo Canada has been working on is regarding the next generation of skilled trades workers. “Saniflo Canada will be donating up to 20 scholarships to plumbing apprentices attending Ontario colleges in 2022. Scholarship donations will cover Level 1, 2 and 3 plumbing apprenticeship tuition, plus book costs for students,” said Warren. The Saniflo Apprentice Journey Plumbing Scholarship is done in collaboration with Support Ontario Youth and the scholarship will provide students with hands-on product training. Additionally, the company plans to partner with Wearth to plant 2,000 trees in Saskatchewan this year.

Saniflo Canada prides itself on its six central core values, which include inventiveness, comfort, quality, simplicity, loyalty, and reliability and trust, explains Warren. “Inventiveness is a key part of our DNA. It’s the hallmark of SFA Group, and inventiveness combines creativity, pragmatism, and smartness, encapsulating our ability to identify and offer simple but ground-breaking solutions,” said Warren.

I can’t say enough positive things about Saniflo. They showed kindness to complete strangers and helped us when they didn’t need to. Actions speak louder than words.

There are several factors to consider when putting your inventory plan in place; don’t sweat the small stuff.

This is more likely for inventory such as filters, belts, motors, and faucets. This might also allow their maintenance people to do minor work that shows you care about their bottom line.

You also need to know how much inventory to keep in your vehicles. Certainly, there should be lots of Part C and the most used Part B items—you can’t afford to have anyone rushing off to a wholesaler for a clamp.
