EDITOR’S

Attracting the Predisposed I recently had a chance to chat with HGTV personality Kate Campbell. You might know Kate from her work on television with Mike Holmes and Paul Lafrance, or more recently as one of the celebrity stars of Home to Win. She’s also a graduate of a Women in Skilled Trades (WIST) program, a very talented carpenter and a great ambassador who is focused on changing the face of skilled trades.

Introducing the Trades Know a young person who wants a career? Why not direct them to the Careers in Trades website? The site, presented by Skills Canada and the Canadian Apprenticeship Forum, provides resources for students, parents, educators and employers about trades training opportunities.

Given her history, I ﬁgured I’d pick her brain about intro-to-trades and pre-apprenticeship courses, like WIST, that so many post-secondary schools are offering nowadays.

To be honest, I’ve always been a bit skeptical about the effectiveness of such programs. I think my skepticism is partially because I’ve seen many students emerge from college or university with no realistic job prospects in their chosen fields of study. I also worry that some schools jump on trendy courses since more bodies spells more funding – not the most of noble reasons to extend program offerings. So I was pleasantly surprised when Kate informed me that almost all of her WIST classmates went on to jobs in the trades. I could see her passion for the program as she explained that it was a fantastic doorway to a career. Given her success, and that of her classmates, I cannot disagree, but I still wonder if more cannot be done, especially for our sector. How do we attract grads into the mechanical sector, where becoming a journeyman is often a five-year process on top of the year they’ve already spent in school? These programs are a fine gateway to another gateway, but they extend the timeframe of becoming a professional. I can’t help but wonder whether it would be possible to reduce the apprenticeship tim meline for those who have certificates cert training timeline in trade-related training programs such perrha haps p it could bee possible possible to adjust the apprenticeship ratios to create as these. Or perhaps m re training opportunities mo opportu more for young people who come to the table, and jobsite, with a trade certificate in hand. T ese courses Th coursees are a encouraging students to discover the solid These caareer opportunities opporrtun career available to them in the trades. And the opportunities in the mechanical trades are some of the best jobs out there. The question is how to make our sector the most attractive of the trades these students will be exposed to. Solve that, and we are one step closer to solving the short shortage of tradespeople that is looming.

Goodman is mine. When it came time to find a strategic partner to help take his company to the next level, Mike Martino knew there was only one choice: Goodman. With Goodman on one side and “the best employees in the business” on the other, Martino HVAC became Ontario’s premier HVAC contractor. Service calls were significantly reduced and, along the way, Martino picked up many industry honours including the prestige of being named BILD’s “Trade Contractor of Year” an unprecedented three times. Martino won’t give you all the secrets to his success, but one he’s happy to share is the importance of a great product partner. As Mike puts it, “Goodman is mine.”

Proﬁle Bill Palamar: A Passion for Plumbing and Heating

Ask recently elected CIPH chairman Bill Palamar to describe himself and he’s quick to admit that he’s an entrepreneur at heart. “If there’s one word that deﬁnes me, it’s entrepreneur,” he says. “It allows me to cross a lot of different areas of business… I love to do it; it’s a passion.” That passion and his drive to succeed are not just contained within his company’s doors, however. As a volunteer with CIPH, which he’s

Q A

How did you get started in the industry? I was put in touch with Charlie Hagedorn at CIPH, who had started up Ancon Drains in 1978. He set me up in the agency business. I was just 22 at the time. Charlie was a pure entrepreneur.

been for more than 15 years, he’s more than willing to pitch in to help build the industry that’s been his home for the past 36 years. “It’s all about giving back to an industry that’s been really wonderful to me and my family. That’s really why I do it. There are sacriﬁces that you make to do it, but at the end of the day, it is about giving back to your industry, trying to make it a little better, and leaving it better for the next group coming in.”

As the incoming chair, what are some of the priorities on your to-do list?

The relationships that I’ve developed over the years – the decades, now. What’s the most interesting development you’ve seen in the mechanical sector in Canada? In the boiler business, what’s really evolved is the integration of technology into the heating process. It’s come from the very basic setup to modulatingcondensing, high-efﬁciency, low-emission technology, and controls strategies that are fully integrated. They can do so much more than they could years ago.

boosting I

spend a lot of time writing and speaking about the ever-increasing comfort expectations of the Canadian homeowner. Gone are the days when people were just happy to have a little cool air on those hot, sticky summer nights.

Attaining expected comfort levels in all seasons using a duct system that is designed for one worst day of the year is a challenge, however, so let’s explore possibilities for addressing the hot or cold room complaint by improving or adjusting airﬂow through the forced air duct system serving a home. And yes, we are assuming that typical reasons for overheating or overcooling of the space— such as air leakage, inadequate insulation, poor window performance, or unusual internal gains such from appliances or large numbers of people—have been investigated, eliminated or remediated, leaving airﬂow improvement as the next best alternative.

Measuring AIRFLOW The starting point is to measure the actual airﬂow in the room. I suggest using a properly calibrated balometer, or at the very least a vane anemometer with a capture hood that is calibrated so the resistance of the hood itself is accounted for. I recognize there are other measurement tools available, but after extensive tests I’ve found that a compensating capture hood is the most accurate and repeatable across different supply register types.

Return air pathways are needed to allow supply air into the room.

Measure the flow several times: door open; door closed; and with the return air grille fully open, as well as taped off. This step helps eliminate concerns over whether there is adequate return air for the room. If the supply register flow stays the same or within five per cent, then you know that adding more return capacity will not significantly improve the heating or cooling performance for the room. In other words, you most effectively heat and cool spaces by adding hot or cool air, not by taking ambient air out of the space. Return air pathways are needed to allow supply air into the room. By showing that the supply air is not affected by the presence or absence of return air, you can be confident there is an adequate return air pathway. Be sure to also measure the airflow from the supply register at both the heating fan speed setting and the cooling setting. continues on page 20

Comparing MEASUREMENTS

Taking ACTION There is great value in thorough duct sealing. There are methods to seal ducts, take-offs, elbows and perimeter pipe joints, whether accessible or not. Duct sealing simultaneously increases ﬂow to all supply registers and typically increases the static pressure in the entire system. It also allows for effective balancing of ﬂows throughout the house.

Compare the flows you measure to the expected flow for the size of duct serving the space. Recall that most HVAC designers over the past 30 years have used a supply pressure of 0.15” W.C., as they would have applied the equal friction method of duct design. The basis of the equal friction method is to find the duct run that has the longest effective length. This is the actual dimension length, plus the “equivalent” length of each fitting and accessory along that duct run path. The entire system is then designed using a static pressure (resistance) developed when delivering the required airflow to the “longest” or most restrictive duct run. For example, if this pressure was maintained throughout the entire duct system (and it won’t be), then the expected flowrate in a 5” diameter duct would be 85 CFM, at most. A more reasonable expectation of flow from a 5” duct would be no more than 65 CFM. The chart below shows typical approximate flowrates for common perimeter duct sizes at different pressures. 4” dia.

If the ﬂowrates you measure are near the expected maximum for a given size of duct, then you know that trying to boost airﬂow with some sort of additional fan is unlikely to be effective. You could remedy this by adding an additional duct, or a supplementary heating or cooling system like a ductless mini-split, a wall heater or an additional air handler.

The next logical step is to adjust the fan speed on the air handler. Be sure to measure the total air flow and temperature rise across the heat exchanger and cooling coil to ensure they stay within the manufacturer’s recommended range. This strategy is often more effective when the air handler has a variable-speed fan motor. This can raise the question as to whether retrofitting this type of motor would be helpful in increasing airflow capacity. If the measurements show that additional total airflow can be accommodated across the coils and in the duct system, then a better fan and motor combination may be warranted. The next step would be to damper down shorter runs to increase the overall resistance in the system and thus encourage more air down the longest run. Start with ducts in the branch line serving the space at issue. If these measures don’t increase flow enough to resolve the heating or cooling problem, then an inline fan in the duct to the space may be warranted. After that, duct modifications, duct additions or even zoning options would be the final strategy.

Pressure READINGS You need to measure the static pressure in the supply plenum after the furnace and AC coil (if there is one). In fact, take a number of static pressure readings. The pressure readings are most useful if you also measure the total airflow across the furnace or air handler. The best tool for this a pitot tube array installed in the filter slot. Measurements should be taken at all fan motor speed taps, but at least at the heating and cooling speeds, and at the highest speed setting. Measure the pressure in the branch ducts, specifically in the branch duct serving the room with the comfort complaint. If you have access to the ductwork, measure static pressure at a few locations along the branch line serving the room in question. There will be a drop in pressure along the way; that’s to be expected as air leaves the system along through other supply registers and duct leakage. The drop in pressure helps you decide the strategies available to increase flow to the duct you need it in.

The re-launch of the Nissan Titan is the big news this year. I say re-launch because the new truck bears almost no resemblance to the current Titan; it’s all new and features a 5L Cummins diesel engine. Transmissions continue to gain gears with the last of the five-speeds being retired with the passing of the 2015 Toyota Tacoma. It’s all six-speed and up now with GM leading the pack for 2016 with an eight-speed transmission added to its 5.3L and 6.2L V8s. In fact, transmissions will continue to gain gears as nine and 10-speeds are coming next year. Over at Ford, its secondgeneration 3.5L EcoBoost is coming soon, and has even more torque – 450 lb.-ft, the most of any V6. Currently, the first-generation 3.5L accounts for approximately 45 per cent of F-150 sales in Canada.

2017 FORD SUPER DUTY F250 TO F450 2016 is a carry-over year for Super Duty, but the 2017 is already being introduced as it will be available later this year. Following in the footsteps of the F150, the Super Duty line is going to be built with aluminum alloy. Also new on Super Duty will be a fully boxed frame made with 95 per cent high-strength steel. Ford says towing and hauling capability will also improve, and the 2017 truck line will feature heavier-duty four-wheel-drive components, driveline, axles and towing hardware. The stats provided are for the 2016 Super Duty. Specifics for the 2017 models were not available at time of publication.

PLUMBING

ATTAINING THE

Red Seal The year, if memory serves, was 1984—the same year the Edmonton Oilers hoisted their first Stanley Cup. While they were celebrating, I was sitting in a SAIT campus gymnasium with 1,000 other apprentices attempting to pass the hardest exam of my career: the infamous Red Seal. Trying to write a 125-question exam in a large arena full of students is not very conducive to concentration, but students experience the same thing today— although they can now ask to sit in a separate area. Not writing the exam until around noon can disturb some students, as they have to wait all morning for the biggest exam of their lives. A former student of mine (who eventually became a Red Seal journeyman) once explained to me that he had failed the exam on his first attempt because he’d had too much coffee that morning. He had five cups while waiting for the exam to start. Around 100 questions into the exam, his stomach started gurgling. He made it to the bathroom and returned to his desk with 25 questions left to answer. After another five questions, his stomach took a turn for the worse. Let’s just say he didn’t make it to the bathroom this time—and leave it at that. He ended up scoring 69 per cent on the exam—one point shy of the 70 per cent required for a pass. Fortunately, he stayed away from the java when he rewrote the exam, and ended up passing.

GAINING EXPERIENCE My path to the Red Seal gave me some valuable experience. Back in Ontario in 1977, I worked as an apprentice for a residential construction company, helping with house rough-ins and ﬁnishes. After a year-long leave of absence to travel through Europe, I moved to Edmonton and resumed my apprenticeship working for a commercial construction company. I ﬁnished the last two years of my apprenticeship in Calgary, where I worked for a service company. This would prove especially valuable when I wrote the Red Seal exam, as much of the exam was based on knowledge and experience in a wide variety of the trades—especially service work. I joined SAIT as an instructor in 1992. By then I was a Red Seal journeyman plumber, and I had designed a night course based on service work for journeyman plumbers. I thought this was something that was sorely lacking from the

Alberta curriculum. The course, which is still taught today, focuses mostly on mechanical design and construction, and assumes that students get the rest of their experience and information on the jobsite. I think we might be ready to change the curriculum to include more of a focus on service-oriented themes. The national outline of the current Red Seal requires journeypersons to be well balanced in their experience in order to pass the exam.

FRED’S TOP 5 LIST: RED SEAL PREP 1 Residential Practical Experience 2 Commercial Practical Experience 3 Service and Renovation Practical Experience 4 Service Education Theory 5 Construction Education Theory

The current Alberta curriculum does not really go into much detail for the service industry. It’s a fact that in the past year alone, ﬁnal-year apprentices in Alberta are averaging approximately 60 per cent on the heating, maintenance and service questions on Red Seal exams. This is not good enough, and it can be the difference between passing and failing the exam. Until the curriculum changes to include more service work, we will continue to have problems with students passing the interprovincial exam. Either that or we could increase the length of an apprenticeship. This extra time would give students an opportunity to concentrate on topics and equipment that are most challenging to those writing the current exam. I have continually encouraged apprentices to get as much experience as they can in their trades. At least one year of residential, one year of custom residential, one year of commercial construction and one year of service experience would be ideal. Now, it’s easy for me to say that, but in a tough economy it is sometimes hard to accomplish because apprentices might be worried about losing a good job. That said, apprentices must continue to press the issue with their employers—they need as much experience as they can get. This is absolutely fundamental to passing the current Red Seal exam.

More Than Simple Recall

LOOKING AHEAD After attending the National Apprenticeship Conference in Toronto earlier this year, I learned that a Red Seal journeyperson in the trades is currently on the same financial level as a college graduate. This is very encouraging news. It’s hard to attain the Red Seal—as it should be. I’ve had former university students in my fourth-year class claim that the current Red Seal exam is harder than any university exam that they have written. Our current standards are high, but we should always be careful to write tough Red Seal exam questions that are pertinent to what is truly important and useful in the trade. It isn’t fair to write exam questions on obscure subject matter just to make students guess. We as instructors and government officials must focus on asking tough, practical questions. I believe that the future holds a whole new path for apprentices. I don’t think it will be long before we will no longer worry about what now might be called “cheating.” Students will be given the opportunity to write the exam at their own leisure, at home on their computer with, of course, a time limit of four hours. When this happens, we will not care if they phone a friend or Google the answer. As long as there are at least 5,000 questions from which to draw the exam, and if the questions are shuffled like music on an iPhone, students won’t have time to Google all 125 questions in four hours. The questions could even be harder if you give students the option to “cheat.”

I was taught a long time ago that there are several stages and types of learning. The ﬁrst type that most of us are familiar with is memorizing. We’ve asked people to memorize things for years, but now we are beginning to realize that real learning takes at least seven steps: seeing, reading, watching a video, practical participation, searching the internet, writing a test and reviewing a test. It’s only after these steps that real learning can take place, and a student can be considered to have expertise in their subject. This is what the Red Seal should be all about: learning as much as you can about the vast variety of our trades.

SUBCOOLING TO OFFSET SUCTION GAS SUPERHEAT A

s mentioned in previous articles, some control over the amount of refrigerant solved in the compressor oil can be accomplished by ensuring that a minimum superheat is achieved at the discharge of the compressor. Low compression ratios and/or low suction superheat effectively reduce the discharge superheat. This is especially noticeable in systems that utilize a refrigerant that has a low isentropic exponent. Note that refrigerants having a low isentropic exponent tend to have a lower heat of compression and result in lower discharge temperatures. The chart illustrates the relationship between the heat of compression and the discharge superheat. According to the chart, when using R404A and R507 at the conditions listed, the resulting discharge superheat will be lower than the manufacturer’s minimum allowable superheat. In this situation, the discharge superheat may be increased without compromising the efficiency of the compressor. Using a heat source outside the system will result in a reduction of compressor efficiency. Furthermore, if we were to use the discharge of the compressor to add superheat to the suction line, the compressor will be lower still. Transferring heat from the discharge to the suction is also not a very efficient approach. Using an liquid to suction heat exchanger (LSHX) provides superheating of the suction gas without a reduction in compressor efficiency. This is possible because the heat that is used to superheat the suction gas is extracted from the liquid prior to it entering the evaporator. Since the liquid will be subcooled at this point, each unit mass of refrigerant flowing into the evaporator will be able to absorb more heat. The amount of additional heat that can be absorbed will be equal to the heat added to the suction gas.

Increasing Superheat by Subcooling It is possible to increase the temperature and superheat of the suction gas while simultaneously cooling the liquid entering the expansion device. To accomplish this, an LSHX is used. Although this is a technique that has been around for many years, it has become somewhat less prevalent on modern systems. There are systems in the field, however, that could certainly benefit from the application of an LSHX. Using the compressor manufacturer’s software, the suction gas temperature should be increased to or beyond a point where the minimum allowable discharge superheat is achieved. Since the specific volume of the refrigerant increases with higher suction superheat values, this will reduce compressor efficiency. continued on page 34

Calculating the Subcooling One of the challenges that stems from selecting an LSHX is determining the amount of subcooling that will result from superheating the suction gas. This is important because the refrigeration effect within the evaporator will increase.

USEFULSUPERHEAT The portion of superheat that is absorbed only within the evaporator.

Here is a method that may be used to determine the amount of subcooling that will result.

STEP 1

STEP 3

First, let’s establish our desired operating conditions. This system will utilize R404A, have a saturated suction temperature of 30°F, a saturated discharge temperature of 100°F, no subcooling (just to keep things less complicated), a return gas superheat of 10°F, and with all of this superheat being considered useful.

At this point, we should be sure to set the useful superheat to 10°F since the additional 10°F of superheat that takes place within the LSHX will occur after the refrigerant leaves the evaporator.

In this case, the resulting cooling and evaporator capacities are 184 kBTUH and the EER is 11.86 kBTUH/kW. However, the software also provides a warning message stating that the discharge temperature must be at 20°K or 36°F above the saturated discharge temperature. This simply means that the resulting discharge superheat of 32.3°F is too low. It can be helpful to note that “cooling capacity” is really the compressor capacity, which also includes additional heat picked up after the evaporator.

STEP 2 In order to eliminate the warning message, we need to increase the suction gas superheat. Proceed with a compressor selection that is based on 20°F of return gas superheat and with 100 per cent of this superheat being useful. The resulting cooling and evaporator capacity is 187.5 kBTUH and the EER has increased to 12.09 kBTUH/kW. After increasing the suction superheat to 20°F, we ﬁnd that the warning message no longer appears. At these conditions, we can assume that, among other things, the amount of refrigerant in the oil is low enough that compressor lubrication is not compromised.

After setting the useful superheat to 10°F, the resulting cooling capacity is 187.5 kBTUH, the evaporator capacity is 179 kBTUH and the EER is 11.54 kBTUH/ kW. The reason that the EER has decreased from 12.09 to 11.54 is that the additional superheating that takes place outside the evaporator is not considered useful heat. This is because it was not added by the evaporator, which is providing useful cooling. Since the difference in the cooling capacity and the evaporator capacity is 187.5 kBTUH minus 179 kBTUH, or 8.5 kBTUH, we can assume that superheating the refrigerant by a further 10°F results in 8.5 kBTUH of heat being added to the suction gas after the evaporator.

STEP 4 In order to determine the amount of subcooling required, we need to remove the 8.5 kBTUH from the liquid before it enters the evaporator. In order to accomplish this, we need to increase the subcooling value in the software to a point where the evaporator capacity equals 187.5 kBTUH. This works out to be approximately 6.1°F of subcooling. Therefore, 6.1°F of subcooling adds 8.5 kBTUH to the evaporator capacity. Note that the compressor software output for continued on page 36

STEP 4 indicates a cooling capacity of 196 kBTUH. With this method that we are currently using, we need to ignore this value since the software makes an assumption that the subcooling takes place in the condenser, meaning that the subcooling was provided external to the system. Subcooling that takes place within the condenser is generally referred to as natural subcooling.

Temperature Range

In this example, we started out with a selection that assumed the 10°F superheat picked up in the low side takes place in the evaporator. If only a portion of the return gas condition contains useful superheat, which is typically the case, we will need to factor this in. The reason that we used only 10°F return gas superheat, with all of it being useful, is that low return gas superheat often leads to a requirement for additional superheat when the compression ratio of the system is fairly low and the isentropic exponent of the refrigerant is also low.

This is a point that should be considered during the LSHX selection process, especially when high-glide refrigerants are used.

However, in our case, we know that the difference of 8.5 kBtuh is actually exchanged within the LSHX, from the suction gas to the liquid, and the illustration indicates this. Therefore, we know that the cooling capacity is 187.5 kBtuh and not 196 kBtuh.

Are you wondering why the illustration indicates a 99.3°F liquid entering the LSHX? This is due to the fact that R404A, like all 400 series refrigerants, has some temperature glide. In this case, the liquid temperature leaving the condenser is 99.3°F, so the 6.1°F of subcooling is automatically subtracted from 99.3°F and not 100°F.

Primitive man—caveman, if you will—wrapped himself in animal furs and hunkered down in his primal dwelling to fend off the cold. Then, a breakthrough: man discovered ﬁre, and achieved a new level of home comfort. Did You Know? Years later, there was another paradigm shift. Man invented hydronic heating systems, which proved far more effective— and less hazardous—than open ﬁres.

The Canadian Hydronics Conference is happening in Vancouver this November at CIPHEX West.

Visit ciphexwest.ca for details. The common thread? Progress. Since the days of yore—when dinosaurs ruled the Earth—man has continually strived for more comfortable living conditions. And it is this very progress that has led man’s hydronic aspirations to extend far beyond the realm of home heating. Take, for instance, the use of hydronic systems in barns. On page 62, you can read all about a chicken farmer near Ottawa who had an in-floor heating system installed in a chicken coop. And if you’re wondering what came first, the chickens or the eggs, spoiler alert—it was hydronics! In some cases, hydronic systems have left the home altogether. Why shovel your driveway in the winter when hydronics can do the work for you? Hydronic snowmelt systems are found throughout the country, and now’s the time to start working on them before the first flakes fall. Learn more on page 56.

How to Succeed in the Hydronics Business I

have been involved with the plumbing and heating industry since 1980, and I can honestly say that the secret to success has not changed in all that time.

In the early ’90s I started working for Western Supplies, which was eventually purchased by Emco. After moving into the hydronic heating department there in the mid-’90s, the manager took the time to explain that if I was diligent, studious, and learned hydronics inside and out, I could probably write my own ticket in the future.

Kim is the president and owner of Mechanical Systems 2000, a Calgary-based manufacturer’s agent specializing in hydronic heating. He has 37 years of industry experience.

I wanted to learn as much as I could, so I read everything I could get my hands on, whether it was textbooks on hydronic design or information on products. I also became a sponge when it came to reading about or listening to hydronic industry experts. I would set up training sessions for contractors on Good People, various product lines whenever I could, which Great Knowledge helped me gain their respect and conﬁdence. It’s been said that you hire for I made sure to spend the time to get to know attitude and train for knowledge, my customers on somewhat of a personal level and Mechanical Systems 2000 as well. It is one of my strongest beliefs that this encourages a commitment to is very much an industry based on relationships, continuous training. and this has served me very well over the years. In 1999, I went to work for a manufacturer’s agent—Mechanical Systems 2000, Inc. I have owned the business since 2008, and make a point of fostering relationships every day. Integral to the continued success I have enjoyed within my business is that I have made a point of surrounding myself with great people. You can have the best products out there, but without the right people in place, you will struggle.

If I were to give any tips on how to succeed in hydronics, it would be no different than what would apply to any aspect of life or business: Educate yourself, learn your craft, and pride yourself on fostering great relationships with your customers and the people you work with. Let them know you care. At the end of the day, we are people dealing with people.

hen the Edmonton Excel Society decided to build an addition to its 56-suite Grand Manor facility, Forbes Mechanical was brought on board to build an extensive hydronic heating network, in addition to installing the plumbing and ventilation systems. The task at hand was a large one. Grand Manor was adding a ﬁve-storey building that would feature an additional 64 suites, as well as a ground ﬂoor with conference rooms and a multi-level parkade.

All these areas would be heated hydronically. There was only one issue: the new building would not have its own boiler room. The existing boiler room would have to service all the heating needs in the new building. Andrew Long, commercial project foreman at Forbes Mechanical, and his team were up for the challenge, however.

SPOT

PRESSING THROUGH CLAUSTROPHOBIA Installing a hydronic network in a building that didn’t have its own boiler room called for some creative thinking. Long and his team would have to run boiler mains and a gas line from the existing boiler room into the new building. But how?

Although it provided a solution to the boiler room problem, the chase meant some rather cramped working quarters.

“There was a chase that ran from the old boiler room to about 60 feet from the outside of the new building,” Long recalls. “We measured it all out and cut out a spot where we could drop into it. We ran about 60 feet of pipe underground, connecting it back into the existing boiler room.”

S u p p l e m e n t

“We had to build racks to support all of our heating mains, the gas main and everything that was running through that chase,” Long explains. “After the racks were put in, you had a space that was about four feet vertically and 18 inches from side to side.” Claustrophobia aside, the tight space presented yet another challenge: how would the workers be

This new addition features an additional 64 suites, as well as a ground ﬂoor with conference rooms and a multi-level parkade.

STAYING NIMBLE Adaptability was key to Forbes Mechanical’s strategy when they began work on the Grand Manor addition. “The original drawings for the project called for two 1.5 million BTUH boilers and two hot water tanks,” Long recalls. “But there was no way to get the venting for the hot water tanks and the boilers into the existing basement. “The only access we had to run vents—short of building a new chase all the way to the roof—was an old chimney that had been abandoned. We ended up upsizing the boilers from 1.5 million to 2 million BTUH, and we installed heat exchangers and indirect-fired tanks. We only had to vent two appliances instead of four, and we were able to get it all through that chimney.” The two boilers supply the heating for the addition’s entire hydronic network. “On the main floor of the building, we’ve got a couple hydronic fan coil units,” Long says. “We’ve got some hydronic forced flow heaters in the entryways, and we’ve got four hydronic unit heaters in the parkade.”

“I didn’t know what to do with that kind of space at ﬁrst,” Long recalls. “The gas is what I was worried about. It was a 2-inch gas line running at 2 psi. I had to think about how you could make a connection in that tight of a spot. It’s impossible to crank on a pipe wrench in that, and we didn’t have room in the budget for a welder.

“At one point I was thinking of making all our connections outside the chase and pushing the pipe in. continued on page 46

BALANCING THE SYSTEM It would work, but it would be a pain to do, and if you got a leak halfway down that chase, it was all going to have to come out.”

DID YOU KNOW?

Fortunately, a sales rep from a local wholesaler came to the rescue and loaned Forbes Mechanical a press-ﬁt tool that allowed them to connect all the piping in the chase with press connections. “I had originally slated a week for three guys to complete the gas line,” Long says. “I ended up sending out the two smallest guys I’ve got, and they had it done in a day.” The press tool came in handy for the hydronic system in the parkade as well. “We did the entire parkade with it,” Long explains. “I’d slated three or four guys for a week and a half to cut and thread it all, but all the connections took one guy 13 hours. The parkade is 120 feet long. There are four mains running through it: a glycol pair and a heating pair, so there are quite a few connections.”

Other than having to run pipe through a cramped chase—which turned out to not be so difﬁcult after all—the rest of the project went off with relatively few complications. “Time was the only issue,” Long says. “It’s been a really tight timeline on this job.” With time being of the essence, Long chose to use 130 self-balancing valves to balance the system. “It speeds up the balancing process,” he says. “Instead of having to go through and set everything, everything is running very close to where it needs to be. You just need to tweak it to perfect it.”

FINDING THE SWEET SPOTS

Solar Thermal By Bob “Hot Rod” Rohr

Don’t Let the Sun Go Down on Me!

There are sweet spots where solar thermal technology can shine, but in a world without major incentives, you may need to look harder to ﬁnd them. Look for clients with high, predictable DHW loads. These help the math pencil out. Breweries are one classic example of high DHW loads, along with a consistent use pattern.

he harnessing of solar energy has been a lifelong passion for me. Over the decades I have seen the solar industry rise and fall several times.

In the boom years, typically around high oil prices or embargoes, the solar thermal industry ﬂourishes. I recall one peak where there were solar industry magazines that reached upwards of 200 pages as manufacturers sprouted up across the globe and were clamouring to take part in the feeding frenzy. Of course, the momentum typically wanes just as quickly, usually based on energy costs, incentives and public demand. This makes for a real roller-coaster ride for contractors and businesses trying to be players in the solar industry, speciﬁcally the solar thermal (ST) segment. I believe in ST, and still see a need and desire for it, and there are lots of opportunities. We just need to know what to look for, and how to explain it to our customers. So let’s all do our best to try to keep a sunny disposition regarding solar thermal options and sales, and don’t be surprised if you end up humming that classic Elton John song.

Sell Yourself First

Owners and managers of microbreweries are often keen to embrace clean energy. Showing solar PV and/or thermal presents an independent image, which can match well to the beer they brew. Solar beer just naturally tastes better! Other sweet spots may be found in retirement communities, industrial kitchens and animal facilities, depending on the motivations of the owners or boards of directors.

To get a leg up in the solar thermal game, it can help to become the converted. If you are able to convince or “sell” yourself on the technology, it becomes that much more natural when extolling the virtues of the sun. Learn which types of systems work best in your climate. Read up on the design criteria required to build a successful, long-lasting, trouble-free system. And search out the manufacturers that seem to stay in the game through boom and bust years. Those are the consistent players that can be long-term partners.

Embrace the Simulation When it comes to solar heating, some of the best tools to learn and embrace are the simulation programs. With the proper inputs, a program can predict both the performance and the ﬁnancial parameters of a system. As the hands-on plumber type, I need to know how to size the collector array to the load. How important is the pitch and facing the collectors solar south? What about some shading from trees? All these options can be explored within the simulation programs. With an energy production number in hand, piping, continued on page 50

pumping and component selection are now all possible. This all adds up to an accurate bid or job quote. After the installed system price is established, you can do some financial analysis. You can use the labour and material estimates as your basis for job costing, and you may even be able to calculate some return-on-investment information. The RET Screen program from Natural Resources Canada is described as a “Clean Energy Management Software.” I like that description. This is a powerful tool for energy calculations, and they have great online and phone support. Best of all, the program is free. If you like more flash, the T-Sol program from Dr. Valentin EnergieSoftware GmbH provides colourful bar graphs and energy flow diagrams to help explain and sell the system to the customer. With these programs you can easily change the component selection and run a new calculation. For example, you can run the calculation with different numbers of collectors, or storage tank size options. They also allow you to model the collectors as they would be situated on the roof, so that you can account for any shading.

BY DEFINITION Solar fraction is the amount of the heating load covered by the solar thermal heating system.

I recently ran a T-sol simulation for Calgary and Eureka, on Ellesmere Island. I based it on a system with 320 square feet of collector, 320 gallons of ﬂuid at 140°F set point. Calgary did well, providing a 60 per cent solar fraction. As expected, Eureka was in the 20 per cent solar fraction numbers. Use this information as you may, keeping in mind the simplicity of a solar thermal system with copper on the roof, a copper heat exchanger in the tank, and one inexpensive moving part, the circulator pump.

BRIGHT NEWS! Did you know that

It is realistic to expect a 20-year life cycle from the system, and some copper recycling at the end.

Calgary, Winnipeg,

And once the solar thermal system is up and running, very little maintenance is required. Most locations get enough rain or wind to keep the glass clean. In dusty climates, like perhaps the Sahara desert, an occasional washing would be required, but that will most likely not be a concern in Canada.

all show over 2,300 hours of

Regina and Saskatoon sunshine per year, and Calgary claims 333 days of ’shine? Remember, it does not require a bright, sunny day to collect energy from the sun. I’ll occasionally hear our home ST system kicking on even on light to medium overcast days. Of course, Eureka on Ellesmere Island pops up as one of the least sunny

locations. It can pay to check the simulation software to see if

Over the years, I have looked at trackers for moving the array with the sun throughout the day. All the data I have seen suggests adding additional collectors would be a better return on investment, when compared to the complexity of tracking a piped system.

Jim Smith S

ome people spend years discovering themselves, flitting from job to job in a quest to find their path. Others know what they want and go for it, grabbing the bull firmly by the horns.

Photos: Airisa Photography

Jim Smith falls into the latter category. When it came to choosing a career, he didn’t waste any time ﬁnding a home in the mechanical trades. His eyes were on the prize from the start.

“I joined the mechanical industry one year after ﬁnishing high school,” Smith recalls. “I didn’t want to go to university or do any more schooling, and everyone had always recommending getting into the trades.”

He started out in plumbing, mostly doing pipefitting work, but things really started to heat up when he got a gas burner licence. “I did my plumbing apprenticeship, and then I got my gas-burner B licence,” Smith says. “I was working on boiler retrofit projects for most of my apprenticeship.” That early experience as a gasfitter would serve as the foundation for a career that has lasted more than two decades. Smith is now a Class A gasfitter who owns his own business, Idraulico Mechanical, which specializes in commercial and industrial boiler projects. continued on page 54

What kind of work do you specialize in? I mostly do boiler work—boiler retroﬁts, start-ups, and I do some warranty repairs for a few of the major boiler manufacturers. What’s your favourite thing about working in the trade? I’ve always been mechanically inclined, so I enjoy that part of the job: the physical part of the work, thinking things through and troubleshooting. And I deﬁnitely like the variety. It’s never the same from one day to the next, that’s for sure. What’s the most memorable project you’ve worked on? I really like the industrial projects. For FortisBC, we did some boilers for a compressor station. In an industrial setting, everything is cleaner. There’s lots of space. It’s a pretty amazing facility they have with all the huge compressors and diesel equipment and turbines they have there. What’s your favourite tool in your toolbox? These days, it’s probably my combustion analyzer. What do you do for fun? I like to golf. And I have two kids, so I end up taking them to a lot of their activities. My daughter is 15 and my son is 12. Favourite radio station: I’m usually listening to my iPod, but I’ll also listen to Jack FM. Favourite movie: One of my all-time favourites is The Shawshank Redemption.

vacation spot: FFavourite a About a year ago we went to New York A b as a family. That was a great trip. One place you’d love to visit: We haven’t made it to Europe yet, so I’d like to do that. What’s the most satisfying thing you’ve ever done? I’m pretty happy with the family we’ve created here in the business, and where we are as a company. Biggest pet peeve: Bad drivers, for one. Crazy hockey parents are another. If you had to describe yourself in one word, what would it be? Hardworking Favourite food: Any kind of pasta dish. I’m a pasta guy.

Favourite TV show: Criminal Minds Favourite sport: I’m a big NFL and Seattle Seahawks fan. We go to Seattle a couple times a year to see games. What’s it like being at an NFL game? It’s amazing.

Snowmelting By Rich McNally

BIG

OR SMALL

SNOWMELTING SYSTEMS CARRY THE LOAD

eat transfer. In a nutshell, that’s what hydronic snowmelt systems are all about. Radiant tubing – typically embedded in concrete – carries a warm antifreeze mix to transfer heat to the material that surrounds it. As this heat transfer takes place, the mass of surrounding surfaces gradually warm to just above freezing temperatures. Naturally, a substantial snowmelt system requires substantial BTUs, and that’s why hydronic snowmelt systems require a boiler or boilers with relatively high output. A boiler system with modulation can improve control of the heated surface temperature. Either a fully modulating burner, or the lead-lag staging of boilers, would allow a system to meet the dynamic load requirements for optimal system efﬁciency.

PEX, PE-RT OR EPDM Piping materials for snowmelt systems can be any number of substances, but the three most popular are PEX (crosslinked polyethylene), PE-RT (polyethylene raised temperature) or EPDM-ethylene propylene diene monomer, a synthetic material. These materials are ﬂexible and durable, have good high-temperature properties, and have a proven record for long life and durability.

thermal shock: A BOILER’S PERFECT STORM Snowmelting systems present a unique challenge: high demand and high mass with extremely cold water/glycol temperatures. These operational parameters can create the ideal conditions for thermal shock, which is less than ideal for boilers. Thermal shock happens when extremely low temperature return-water comes crashing into the heat exchanger during a cold start. To prevent thermal shock with a typical non-condensing cast iron boiler, it’s necessary to isolate the boiler from the snowmelt system with a heat exchanger and the appropriate piping, pumping and control set. The new generation of mod-con boilers takes this brutal jab in stride. The broad Delta T from these systems guarantees the formation of condensate, and these new boilers – by design – extract valuable BTUs in the process without the risk of thermal shock. continued on page 58

ON HOME

Here in Canada, one of the foremost snowmelt experts is Don Gibbs, a former owner of tekmar Control Systems. He has inﬂuenced thousands of hydronic professionals in North America over the past 30-plus years. A recent project was Gibbs’s own home, constructed in the Vernon, B.C. area. As a civil engineer by training, Gibbs took special interest in designing a 3,000-squarefoot, three-zone snowmelt system under his driveway. The priority zone, controlled automatically to sense temperature and precipitation, is in front of the garage area. “The snow-melted driveway surface is stamped concrete, which would easily be damaged by snow removal blades or other equipment,” said Gibbs. “So, naturally, warming the slab was the best way to get rid of ice and snow.” Gibbs explained that, under the on-grade, ﬁve-inch concrete slab is a thick layer of compacted gravel. Elevated rebar strengthens the slab and also serves as the support for thousands of feet of 5/8” radiant tubing, located about two inches below the upper surface of the driveway.

TACKLING MISCONCEPTIONS Application of snowmelt is growing. It’s also become one of the most askedabout heating systems in Canada. A common misconception about snowmelt systems is that they cost a lot to operate. Most of them only operate in the presence of ice or snow, however. Furthermore, typical snowmelt systems only operate for brief periods at a time. Because of this, systems usually cost about $0.25 per square foot per year to operate – and that’s in higher snow areas. When building owners ask, tell them to compare those prices with manual and chemical methods used to keep surfaces free from ice and snow. There are safety advantages as well. Can a medevac helicopter afford the risk of landing on a frozen rooftop? Can the team rushing from it do so safely if they’re sliding on ice? Down below at the front door, though perhaps a bit less dramatically, patients and visitors may be at risk if snow and ice are present on the walkways and parking lots. Consider the advantage of greatly reducing an institution’s liability exposure when selling a snowmelt system.

ONLY IMAGINATION LIMITS THE USE OF SNOWMELT Walkways, driveways, commercial trucking ramps, hospital entrances and helipads are great uses of snowmelt. Drainage systems are another good application for snowmelt technology. Water, once it goes below ground and away from the warmth of the sun, might otherwise freeze. Also, “hot pads” are another application. These are areas for large parking lots, airport runways and other large outdoor spaces where snow is deposited for melting. It’s often cost-prohibitive to install piping to melt an entire airport runway or parking lot. So, to accomplish this, a concentrated amount of piping can be installed in an area where snow removal crews can dump snow. The pad melts the snow. These are fantastic for areas where snow disposal would otherwise be a problem.

MULTIPLE ZONES, MULTIPLE TEMPERATURES – PART 2 You are looking at a primary/secondary, series, multizone, multi-temperature system drawing – how’s that for a mouthful? One of the secrets to ensuring that the four zones of heating get the BTUs each needs is in the spacing of the tees. And remember, the main piping should be sized for either the maximum ﬂow of the boiler or the distribution system. So, based on what we know, and the additional information in the questions, let’s do some designing. 1. The total heating load, based on all four loads on design day, is 150,000 BTUH. What size of high-efﬁciency boiler would you recommend? a) 150,000 BTUH net b) 175,000 BTUH input c) 100,000 BTUH net d) Another size: _____ BTUH 2. If this was a combi-boiler doing DHW as well as the heating load, what size would you pick? a) 150,000 BTUH input b) 175,000 BTUH input c) 140,000 BTUH input d) 190,000 net BTUH e) All might run, but we need more info on the DHW requirements for proper selection. 3. What is the correct size piping for the air handler? a) 1/2”, like the connections on the unit. b) 1” would work. c) 3/4” is the right size. d) 1-1/4”

Project Proﬁle By Jerry Leyte

Playing Chicken with

PEX

hat do you do when you are installing an in-floor heating system for a poultry farmer who has already ordered the chicks that are supposed to inhabit the barn that you are still building? First step: breathe. And then you double check your dimensions and heat load requirements and go looking for heating system options that will minimize the time it takes to go from a gravel base to an installed in-floor heating system slab. A poultry farm normally orders day-old chicks from a hatchery, raising them for approximately eight weeks before the birds are harvested for food. When Tony and Wilma Baas, the Ottawa-area farmers whose barn was being built, informed the plumbing team at Fernand Denis Inc. that their first shipment of birds would be arriving on a scheduled date, Pascal Denis knew that the building had to be ready. There was no wiggle room for him—or for the chicks.

Project: Russellview Chicken Farm Location: Ottawa area Mechanical Contractor: Fernand Denis Inc. System Designer: Klimar Agency Inc. General Contractor: Brian Shane Construction

Pascal reached out to Klimar Agency to assist in the design of the radiant heating system. Since timing would be the driving factor in the success of the project, he opted to use prefabricated radiant rollout mats of PEX, which would be enveloped in concrete to make the radiant slab. These would be part of the 1 million BTUH in-ﬂoor hydronic heating system used in the 64-by-400-foot structure.

Total Area: Approximately 24,287 square feet Designed Heat Delivery: 38 BTU/sq. ft. Loop Lengths: 400 ft. (max.)

Radiant heating systems are more common in poultry barns than forced air heating systems, but the most common style of radiant heaters are overhead tubestyle or pancake-style “brooders,” as they are known in the poultry industry.

Spacing: 9” on centre

This particular farmer took it up a notch and opted for an in-floor radiant heating system. An in-floor radiant system has the additional advantage of even heat distribution throughout the entire floor surface, versus the hot spots that can get created directly under the traditional overhead style of heaters.

Supply Water Temp: 125°F

Consistent ﬂoor temperature in all sections of the barn leads to even distribution of the birds in the space, instead of having clusters of birds under a heater when they are cold, or bare spaces on the barn ﬂoor when an area is too hot.

Head Loss per Mat: 14 feet

Although radiant mats are somewhat more expensive than spools of PEX, the cost can be offset by the labour required to install the piping, and the fact that the mats could be installed in a small installation window made them a viable, and attractive option for this project. As each mat is custom-built, Pascal placed his order weeks ahead of his scheduled installation date, so that they could be built to his speciﬁcations while the frame and walls of the building were going up. continued on page 64

LAYOUT OPTIONS ABOUND

continues from page 62

Not leaving any timing to chance, Pascal actually drove to the supplier to pick up the product himself, rather than having it shipped and risk a delay from a third-party logistics company. This ensured that the tubing he needed would be on his site when he needed it – an extra step for Fernand Denis but an impressive level of customer service that showed the company’s commitment to their customer, the project and the welfare of the animals. The use of the mats on the project helped keep the build on its tight schedule. Pascal’s crew was able to install almost 25,000 feet of tubing in a single day (see the QR code on the previous page to watch the installation video). Starting at 7 a.m., the tubing was in place and ready for the concrete pour by 1 p.m.

With everything up and running in a couple of days, the farmer was able to ﬁll the barn with chicks, as scheduled.

GETTING LOOPY

When working with mats containing a reverse return header, you will have to

Available from a number of manufacturers, these mats of PEX tubing are rolled out prior to a concrete pour. Depending on the size of the area being covered, the mats can be as narrow as a few feet, or as wide as 10 feet. Lengths can be up to 200’ long, and contractors can select the tube diameter and spacing that best ﬁt their project.

MOVING RIGHT ALONG

With the piping in place, the system was pressurized with air to approximately 80 psi to ensure no leaks were created during the concrete pour (4” slab using ﬁbremesh concrete) on the following morning, at which point the focus turned to commissioning the heating system.

Prefabricated mats can be configured in a standard looping configuration with each long loop feeding back to the supply and return of a standard radiant manifold, or they can be configured with a reverse return header incorporated, which ensures that all of the loops are properly balanced.

There are a number of methods that can be used for laying PEX tubing on commercial radiant ﬂoors, but perhaps one of the newest and most novel is the use of pre-fabricated mats.

ensure that the manifolds being used have sufficient flow rate capacity to meet the requirements of the mat. For example, a 42” wide mat of 1/2” PEX with 6” spacing will have four loops, and therefore need a four-loop manifold, if it’s not being used in a reverse return header configuration.

As chickens get older, they require less heat, and the heating system gets turned down based on needs of the birds. A zoned radiant ﬂoor heating system can actually be a great way to move birds from one section to another, for cleaning purposes, or as they grow. Simply turning zones off or on causes the birds move to the section you want them to inhabit. Adjusting the temperature of the zones, warmest for new birds, and progressively cooler at the other end, with a few isolated zones in between containing birds of various stages of growth, is a common approach in large barns where day-old chicks enter one end of the building and eightweek-old birds leave the other.

If this mat is configured in a reverse return header format, those same four loops of 6” spacing will all be linked via the header and a single supply and return line from the mat will be connected to a single supply and return on the manifold. This single connection will need to have four times the flow rate of a single 1/2” loop in a standard looping configuration, however.

Marketing with DOUG MACMILLAN

The Art of

Communicating Complex Things W

e’ve all been there: You pop into a store to understand what plugs into what, again. A keen clerk launches into a detailed, confusing narrative about how the thing was invented and built; what makes it work; why it’s better than others without the patented recalibrating such-and-such; and how it could actually be set up so you can binge-stream television while recharging your toothbrush in a few quick and easy steps – steps that are never easy or quick. Doug MacMillan is president of The Letter M Marketing in Guelph, Ont. To reach him, email doug@thelettermmarketing.com.

Before we can say Netﬂix, our eyes glaze over and our minds drift away. They’ve lost us, and we still don’t know what plugs into what. It’s the age of information overload – a time when anything we want to learn is available after just a few strokes on a keyboard. As such, there will be those who feel the need to dig far deeper, and share far more, than the level of information the average consumer needs or wants. But to be most effective, the sharing of information has to be at an appropriate level for the audience. Sure, you will bump into customers who are keen to learn all about the inner workings of a radiant ﬂoor system, how pressure balancing works, or the difference between a two-stage and a modulating furnace, but most of us regular folks are looking for information in plain language, at a level we can understand. The contractor who can best provide this knowledge in an understandable, concise way has a leg up over the guy who takes us on a deep and technical journey we can’t begin to comprehend.

Don’t Patronize A word of caution: Keep an eye on the ﬁne line between sharing information in simple terms, and being patronizing. Assume your audience is intelligent – simply uninformed.

How to Share Over many years of speaking with contractors about how to discuss technical systems with customers, I’ve put together some of their best advice on how to give folks the technical details they need without overexerting anyone’s brain.

Don’t overshare. Most of the

time, people who know a lot about something are quick to dive into the uncondensed version. Step away from that ledge. Don’t assume everyone needs the full back story. Read the room and tell them only what they need to know or are asking about. The curious ones will ask more questions if they need more answers.

Avoid jargon and acronyms.

tend to bog us down in jargon, but people primarily need to understand the beneﬁts – how the product will make their lives easier, more comfortable or better. Focus on that, rather than the features or systems that allow it to deliver those beneﬁts.

Sizing and Installing

Tankless Technology O

ver the past decade, tankless water technology has garnered considerable attention and growth in market share. A recently conducted industry study projects that by 2020 the tankless water heater market in North America could surpass $4.3 billion. That’s a lot of water heaters, but it will be up to contracting ﬁrms to provide solid installation, service and sales information to maximize their opportunities. Contractors need to ensure that the units being sold will live up to their billing. This means ensuring that the water heaters are sized appropriately.

Calculating Efﬁciency Tankless water heaters are rated using a calculation called an energy factor (EF). The higher the EF, the more efﬁcient the water heater. Gas tankless water heaters typically have EFs that range from 0.64 to 0.98, with an average of 0.85.

To properly size a gas tankless water heater, a contractor first needs to determine the litre-per-minute demand, or flow rate, at each fixture. It is particularly important to add up the flow demands for those that could occur at the same time – such as two showers at once, or a kitchen sink and shower. Being realistic about the demand will keep you from both over- and under-sizing the water heater for your client. It will also determine the maximum temperature rise needed to run all the hot water applications in a home or building at a given time. Temperature rise can be determined by subtracting the incoming groundwater temperature from the continues on page 74

INSTALLATION CONSIDERATIONS:

RESIDENTIAL

The number of fixtures or outlets in a residential home or apartment complex affects the number of tankless units required. Residences with more than two bathrooms, a kitchen sink, washing machine and dishwasher may require two tankless units. In that case, it may be better to zone the house. Water heaters can be strategically placed in the home and each unit can be dedicated to certain water fixtures/outlets. This creates a decentralized hot water heating system, which can limit the pipe runs between each tankless unit and the fixtures it is supplying. This can help reduce the amount of cold water wasted down the drain while residents wait for hot water. continues on page 74

PLUMBING desired output temperature (for most uses, a homeowner would want water heated up to 49°C). Use the coldest possible groundwater temperature for your immediate area to ensure the water heats up quickly, even during the most frigid winters. Don’t forget that distance can also affect hot water delivery. The longer a hot water pipe runs between the hot water heater and a fixture, the more likely it can result in reduced hot water temperatures at the fixture, especially if the pipes are uninsulated. As such, insulate the pipes, but then be sure to factor in any remaining temperature drop from the length of your pipes when calculating the temperature rise needed. Size also can be determined based on BTUs. For example, a gas tankless heater with 199,000 BTUs per hour can handle two to three major applications (showers, dishwashers, washing machines) at once without issue. Gas tankless water heaters offer an energyefficient option for hot water supply for both commercial and residential buildings.

continued from page 72

INSTALLATION CONSIDERATIONS:

RESIDENTIAL CON”T

Another water-saving option is a domestic hot water recirculation system on a centralized hot water heating system. Tankless units can be installed in a mechanical room or central location in a home, with hot water lines running to all the fixtures from there. This may create a long pipe run from the mechanical room to the farthest fixtures, and thus longer waits for hot water, so a contractor can put in a hot water recirculation system. Controls can be used to ensure that hot water in the main line is circulated in the system during appropriate times of the day. If a home has remote fixtures that don’t get a lot of use, say a half-bath in a larger house, it might be an idea to explore point-of-use options. This can reduce the cost and labour of running a hot water line directly to the application, and electric under-sink tankless or mini-tank units are available to provide hot water right at the point of use.

INSTALLATION CONSIDERATIONS:

COMMERCIAL

Athough it is possible to install enough tankless units to accommodate all hot water use in a commercial building, contractors may wish to combine tankless and storage units to offset the number of tankless units needed, rather than installing numerous tankless units to address peak demand. For example, in a large hotel development, peak demand could be a two-hour timeslot in the morning as guests are showering before going to work or checking out. The cost to install enough tankless units to meet that once-a-day peak demand could be prohibitive to the owner, especially since the number of units required to provide enough hot water during peak demand may be overkill for the rest of the day. In this case, the contractor could use a tank-loading application, which combines storage and tankless units. The storage units buffer the supply of hot water during peak demand, and the tankless units help recover the storage tank more quickly than a typical direct-ﬁred storage tank would on its own. This application also offers higher efﬁciency because the tankless units are still condensing during the heating cycle.

With the growing tankless market, contractors who understand how to size and install these units will be set up for success.

DON’T FORGET TO VENT Tankless units require proper venting. They generally use two- to three-inch-diameter vent pipe and do not need to be vented like a chimney, although that still is an option if necessary or desired. Gas-condensing tankless water heaters emit a cooler exhaust gas than most noncondensing fuel-burning appliances, so the exhaust vent can be an approved S636 plastic, with PVC, CPVC and polypropylene being common options.

CELEBRITY ENCOUNTER

Houses of History

By Adam Freill

The Olympic Games are not just about the athletes; there are the cities, the cultures, the citizens and the buildings to take in as well. For Russell, the buildings where history has been made hold a special place in his heart. “Every time I visit somewhere internationally, whether it’s on holidays or for work, I always want to see the Olympic stadium,” he shared. “I went to Germany, to Berlin, in advance of the FIFA Women’s World Cup in 2011, and I made a point to see the Olympic Stadium in Berlin.” That arena hosted the 1936 Games where Jesse Owens became a sporting legend, much to the chagrin of Adolf Hitler. “It was a fantastic structure, and remains a beautiful gigantic stadium to this day. “For Rio, the stadium that I have heard so much about, but have never been to, is the Estadio do Maracana, where they are going to have the opening and closing ceremonies.” At one time the largest stadium in the world with a 110,000-seat capacity, Maracana now seats 75,000. “Pele played there,” explained Russell of his desire to visit. “It is the mecca for South American football, and I’m sure it will be spectacular for the opening and closing ceremonies.”

cott Russell is an unabashed Olympic booster, and he’s looking forward to adding Rio to his long run of moments and memories. “It is the greatest spectacle,” stated the Gemini Awardwinning broadcaster during an exclusive interview with Mechanical Business prior to his departure for Rio for the 2016 Games. “No other event in the world can bring together 10,000 athletes from 200 countries, of every faith, race, gender and orientation – only the Olympics can do that.” Asking Russell, the host of Olympic Games Primetime and Road to the Olympic Games (both on CBC), to pinpoint a lasting moment in time from the dozen Olympics he’s had a chance to cover as a journalist easily elicits dozens of memories – some that affected him personally, and others that were broadcast for all to see. “I’ve been to 12 Olympics, beginning in Seoul in 1988, and the awe moment for me begins when you ﬂy over Seoul

and the sun is setting, and it is a place that you have never been before, and is completely foreign to you, and exotic,” he reﬂected. “To me, that’s what the Olympics always represented when I was watching them as a kid. They were this great spectacle in a place that I knew nothing about, but was going to learn something about.” Move forward to Beijing, 20 years later, and Russell ﬁnds himself once again in awe as one of the greatest gymnasts of all time runs along a guywire to light the Olympic cauldron in front of a capacity crowd of 90,000 spectators in the famed Bird’s Nest stadium. “I had covered gymnastics for a number of years for the CBC and knew who Li Ning was, and to see that happen, in China, at those Games, was jaw dropping,” he explained. “I believe in the aura of the Olympic Games. To my way of thinking, it is greatest recurring spectacle on the face of the Earth.”

Have Venue, Will Travel

From Passion Comes Success

Modern Olympic venues often incorporate unique architectural features. For example, built for the Beijing Games, the Beijing National Stadium – known more familiarly as the Bird’s Nest – uses a rainwater collection system, as well as a geothermal heating and cooling system.

What’s it take to be an Olympic champion? Russell has interviewed hundreds of athletes, and numerous medalists, so we’ll bow to his observances.

At this year’s Games, the concept of nomadic architecture has been embraced. Several of the venues are considered to be temporary, and have been built as modular structures that will be disassembled and moved for use elsewhere once the Games are done.

“Over the years of years of seeing these athletes, I really believe that they have a complete passion for what they do,” he says. “It is their life. It is their work. And you put those two together and it is their life’s work. So they are unalterably committed to it. “You have to have that passion for it; otherwise you just can’t get there. It’s this intangible called passion. “I read all kinds of stuff where people are saying these are coddled athletes; they are pros; they live a great life; they travel the world; what have they got to complain about? But I really believe they are tremendously committed, passionate Canadians who put a lot at risk by shouldering those expectations and representing their country on a world stage. I think their story is really worth telling, and I believe in them.”

“The big one that is going to be nomadic is the swimming pool, the aquatic stadium,” explained Russell. “That’s becoming a bit of a trend for aquatic venues. It goes back, in my recollection, to the 2005 aquatic championships in Montreal, on Ile SainteHelene, where they constructed four or ﬁve Olympic-size pools, and only two of them remain. The others were disassembled and moved.” Also on the move after the Olympics and Paralympics wrap up is Future Arena, where handball will be played. Its components will be used to build four schools in the region. “I think, at long last, that Mr. Bach, who is the president of the IOC, realizes that the Olympic Games have to be sustainable. We can no longer, in countries where economies go through ups and downs, build these enormous stadiums that become white elephants that we can’t move.”

Rio 2016 on CBC Canadian viewers will have access to more than 1,275 hours of television coverage from Rio 2016 from August 5th to 21st. Daily coverage starts at 7 a.m. (EST).

Building on the Past In the lead up to any Olympic Games, there are always stories about construction progress on athlete villages and various venues, with headline-hunting writers always on the lookout for build sites that are pushing the deadlines as the competition comes into view, but according to Russell, Rio was a pleasant exception.

Scott Russell’s Can’t Miss Event: The Men’s 100 Metre Final “It is the world’s fastest man, the world’s fastest human being, and it’s mano a mano, no mistakes. It happens in less than 10 seconds, it’s over in a blink of an eye, and it is like ﬁreworks going off.”

“One of the things that’s interesting about Rio is that many of the buildings are a legacy of the 2007 Pan American Games,” he said. “In terms of venue construction, with the exception of the velodrome, which is a new construction, they were miles ahead of many other Olympic cities that I had seen in the past.” M e c h a n i c a l

CONDENSATE MANAGEMENT

essentials A

s the ductless mini-split air conditioning market gains more traction in Canada, specifiers and installers find themselves faced with the ever growing challenge of condensate management. Mini-split indoor units are typically located in plain view of the room they’re conditioning. Also in plain view is the potential water damage caused by overflowing drain pans, especially on interior wall installations. This water can severely damage walls, wood floors and ceilings. Overflowing drain pans can also create health-compromising mould, mildew and other biological growths behind walls, under floors and above ceilings. There are preventative maintenance measures that HVAC engineers can specify and contractors can install on mini-split and even variable refrigerant flow (VRF) indoor coil applications, however.

DRAIN HOSES

MATTER Not all drain hoses are the same. Some types of tubing used for gravity draining can be prone to kinking. A kinked hose can allow condensate to back up into the drain pan and overﬂow. Corrugated drain hoses made speciﬁcally for mini-splits are designed to resist kinking. Another drain hose challenge stems from unconditioned spaces, such as attics or crawl spaces. The cold surface of an uninsulated hose can attract moisture (sweat) in an unconditioned space. This moisture can drip onto other surfaces, causing moisture damage or nurturing mould. Using a thick-

OVERFLOW SWITCHES:

ADD A

TRAP

The Last Line of Defence Mini-split indoor coils don’t have the secondary drain pans that many unitary ducted air conditioners are equipped with, so an overflow switch can be the last line of defence against property damage during a condensate drain or drain line blockage. Canada has yet to adopt an overflow switch code, but both the International Residential Code (IRC) and the International Mechanical Code (IMC), which are used around the globe, require a primary drain pan overflow switch on any air conditioning installation that is not outfitted with a secondary drain. Some overflow switches come with options like diagnostic lights, but the main function is to cut off power to the unit so that it can’t operate and produce more condensate if the drain has been impaired. An overflow switch is inexpensive insurance against property damage. It can also be used in conjunction with condensate pumps.

Mini-split drain hoses should include an inline waterless trap, which is an inexpensive and essential device that prevents insect, dirt, humidity and allergen infiltration. An inline trap uses a check-valve device that allows condensate to flow out, but prevents unwanted pests, summertime humidity or wintertime cold air into the conditioned room via the evaporator. Even a small infiltration of unconditioned outdoor air can decrease system efficiency. For even more protection, the trap’s check valve door is sensitive enough to open from the weight of an ounce or two of water, preventing water from accumulating, which could damage the trap during freeze/thaw cycles over the winter.

PUMPING CONDENSATE AWAY Another insurance policy against propertydamaging drain pan overflow events are condensate pumps. These are required for all internal wall installations. There are many variations (see Illustration A), but typically a mini-split condensate pump consists of a pump body, a separate reservoir that includes a filter and a pump-activating switching mechanism. Sometimes an integral overflow switch is included in the design, and some pumps have pump bodies that are mounted remotely. Other designs combine the reservoir and pump body into a single unit.

This is known as a monobloc pump. Many pumps include two cable connections, a 115-V or 230-V power connection, and an overﬂow switch cable, commonly wired into the air conditioning equipment’s communication cable to shut down the unit during an overﬂow event. The four most common mistakes associated with mini-split condensate pumps are: • Omitting a pump; • Creating a siphon by applying improper hydraulic design in the drain hose installation; • Wiring incorrectly; and • Selecting the wrong pump for the application or location. Selecting the proper pump depends on such factors as the equipment’s cooling capacity, maximum head and suction lift, operating noise, installation and maintenance ease, and appearance.

DRAIN PAN TABLETS The main culprits in drain blockages are mould and other biological organisms. As such, a biocide drain pan tablet designed for mini-splits can help keep the drain pan, hose and condensate pump ﬁlter clean. This can be added when installing the unit, or during routine maintenance. There are two types of drain pan tablets. One is simply a non-biocidal chemical that coats the pan with a slick surface that helps prevent debris from sticking. The other type is a biocide containing a disinfecting chemical such as chlorine. Not all biocide tablets are the same. Some conventional biocide tablets may be too corrosive for the typical aluminum ﬁns used on mini-split indoor coils. Alex Frean is the international sales manager at Rectorseal Corp., a company that offers a range of mini-split installation and maintenance accessories.

COHA Focuses on Image in Charlottetown By Darcy Cudmore Modern oil heating has an image problem. It is not the dirty fuel that many envision when thinking about heating system options, which is why the themes of cleanliness and safety were among the many messages shared with delegates during the Canadian Oil Heat Association’s annual conference, Cleaner Heat. Over 100 people involved in the oil heating sector gathered in Charlottetown to participate in the two-day event in June. Things got rolling with keynote speaker Michael Duck, founder of Sure Shot Solutions, who shared business advice with the owners and managers in attendance. “Attitude has more to do with success and failure than any one thing,” he explained. “Eighty-ﬁve per cent of people achieve things by attitude, 15 per cent by aptitude. It’s all aboutt having a positive attitude.”

One issue highlighted during the event as a way to help maintain a clean image for the oil heating industry was the reduction of spills. As such, in addition to talking about expanding COHA’s GreenTech Program, COHA president Stephen Koch led a session about spills and the importance of collecting data on the subject. He discussed the need to establish an information hub that will help with the collection and distribution of information about oil systems and spills.

“The industry has to pay attention to the data that’s being collected to make sure that when people spend a lot of money on a new setup, it actually does reduce the risks of a spill,” said Michael Freill, president of Mark 1 Engineering, to the room. Koch touched on the relationship between the government, insurance companies and those involved in the industry, and how accurate data collecting can help reduce and limit oil spills.

1. Keynote speaker Michael Duck spoke on being successful and the importance of a positive attitude. 2. COHA president Stephen Koch kicks off the annual conference’s ﬁrst session by addressing the importance of the event, as well as the new GreenTech program that COHA has started. 3. Sean Hiscock explains the beneﬁts of having a Red Seal in the oil heat industry in Canada. 4. Phillipe Roy of Granby (left) chats with an attendee during the Canadian Oil Heat Association’s annual conference. 5. Holland College HVAC instructor Charlie Redmond joins (from left to right) Alan Gaunt and Bernie Jackson of Humber College and Sean Hiscock from the Nova Scotia Community College on an education discussion panel with members of the industry. 6. General manager of Datanova, FelixAntoine Rollin (left), shares a laugh with incoming COHA chair Dave Brown of Western Petroleum before COHA’s annual conference gets started in Charlottetown. 7. Bernie Jackson, an instructor at Humber College, speaks to the room about education.

“It’s much easier to speak to an insurance company or government when we have data to back up what we’re saying,” Koch said. The next edition of Cleaner Heat comes to London, Ont., in June of 2017. coha.ca

TOOL TIP

Tool Kit, or Not Tool Kit? Q That Is the Question

hen it comes to cordless tools, combo kits containing two or more tools from a single company can be an attractive purchase, since the kits often offer considerable savings when compared to the costt of buying individual tools. ols. But kits generally lack ck the ﬂexibility to choose ose which tools are included, so they may not always be when b the h best b choice h h tooling l up. Here are a few things to contemplate next time you are in the market for a new tool or two, so you can decide whether to go kit, or kitless.

IMAGINE THE POSSIBILITIES WITH SAMSUNG • Reliable Performance • Exceptional Design and innovation • Easy trouble shooting (Smart check) • Smart WIFI

KIT IT UP - BENEFITS OF A KIT • Use of the same battery for multiple tools, and inclusion of a charger. • Available trade-speciﬁc kits. • Pricing: Generally much cheaper than buying each piece individually. • Maintenance: All tools in the kit are the same age, which can simplify scheduled maintenance.

GOING SOLO - WHY BUY TOOLS ON THEIR OWN, RATHER THAN IN A KIT? • It’s a way to avoid buying duplicate tools. • Tool selection is ﬁxed in kits. Buying individual kits allows tradespeople to customize to their needs and preferences. • Ability to buy bare tools from some manufacturers, reducing the overall cost since the user makes use of the batteries they already own.

with Roger Grochmal

If Someone Else Can Do It, Should You?

often get asked what the most important tant skills are for an owner ing business. One skill that or manager of a mechanical contracting is often overlooked, but one that I consider onsider to be essential, is the art of delegation.

It’s harder in practice than it is in theory, yy, but empowering others is critical when you are looking to o grow your business. 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.

Success via Succession The main task of a manager is to develop a successor. I can remember very early in my career when I was passed over for a plum promotion, so I asked my boss for an explanation. He said that it was simple: I had not developed a successor who could do my job and allow me to move up.

Delegating enables the people who workk for you to gain the experience and skills you need them to learn, so they can take on higher responsibilities sibilities and reach their fullest potential. It also allows you, the owner, to stay focused on the things that represent the best use of your time. Done well, it will build the team you need to grow your business, and it should likelihood having decent work-life balance – ld iincrease the h lik lih d off h i ad k lif b l this is important for any entrepreneur interested in a long career. Similarly, there are lots of reasons (aka, excuses) that managers make for not delegating. Most of us are good at what we do and have trouble delegating when we think the outcome may not match what we would do. Not only that, but delegating can take a lot of upfront effort. In the short term, it can stretch out the time it will take to complete a project. We also tend to obsess over the potential cost of mistakes, and our egos can also get in the way. But to get the benefits, we need to push aside our pride and show respect for the talent that others in our organizations can bring to bear on an issue. Delegation is not just about getting some work off your plate so you can have a personal life. It’s about developing the people around you to drive your business forward. Failure to become an effective delegator will limit your ability to grow your business.

IT’S NOT “DREADED-TASK AVOIDANCE”

Twelve months later, I had my successor in place and I was able to get that promotion when the incumbent retired. A painful lesson learned.

Don’t submit to the temptation to delegate the things you don’t like to do. Delegate the things you do well – when you do, it’s a lot easier to follow up and coach your employee through the task.

WHEN TO DELEGATE Delegating a task is not always appropriate, of course. So when is delegation appropriate? When you can say yes to these questions:

• Is there someone else with the expertise to do the job? • Can it develop the skills of someone else on your team? • Will it likely reoccur in the future? • Do you have the time to delegate the task effectively?

STEPS TO EFFECTIVE DELEGATION • You have to trust the person to whom you are delegating the task. • Delegate to the people who are closest to the action, and who represent the lowest cost to the business to complete the task. who will deliver results, not those who are least busy. • Give work to people p • Clearly define the t task, the desired outcome and what success will look like. • Always make it clear why the task is being delegated. Why is it important and relevant? • Make sure you yo provide the resources required for the project to be successful. This is often where things go off the rails. • Ensure you, or another manager, are available for mentoring g and to give feedback on results. • Agree on a deadline and checkpoints along the way to measure asure progress. • Match the amount of responsibility being delegated with the authority to do the work. am • Avoid reverse delegation where the work seems to find its way back on to your d other hand, don’t micromanage. plate.
