EDITOR’S

When governments pick favourites, we all tend to lose Watching the on, partially on, likely off scenario of green incentives in my home province of Ontario has had me reﬂecting on the issue of governments picking favourites when it comes to technologies to incentivize, and how often government agendas have caused turmoil for industries and end consumers.

Visit us online Want to stay in the know, even during your summer vacation? Catch up on the latest news on our website, mechanicalbusiness.com, and be sure to follow @MechBusiness on Twitter.

Over the past several months we’ve seen a program to push heat pump technology go from an incentive plan targeting all homes in Ontario, to a small subset of homes in the province, to a likely cancellation for all but those already in the pipeline from that small subset. Considering that wholesalers need to plan out seasonal purchase agreements with manufacturers, and manufacturers need to adjust production long ahead of demand, I don’t think I need to delve into the challenges that the constantly changing incentive plan presented to our sector suppliers. And the picking of favoured technologies is not just an issue in Ontario where we’ve just seen a considerable swing in political will with the recent provincial election. Municipal governments, provincial governments and the federal government have all spent time trying to push consumers down speciﬁc pathways.

At least one municipality is proposing to reduce the allowable flow rate of kitchen faucets to 6.8 L/min from the current 8.3. If that flies, consumers will end up spending more time filling sinks for dishwashing and pots for cooking, possibly having to use more water as they try to keep dishwashing water hot.

Inspectors meet in St. Catharines “The human body at rest transfers heat at a rate of 400 BTUs per hour,” explained Gilles Legault of CB Supplies during his hydronic systems presentation, one of several presentations given at the Ontario Plumbing Inspectors Association’s 2018 Annual Meeting and Education Seminar (AMES), held in St. Catharines in mid-June. He explained that Rainier Blundel outlines some the goal of a heating or cooling of the pitfalls to watch for when inspecting a plumbing system system is to create equilibrium during OPIA’s AMES 2018 by transferring heat via radiation, conference. evaporation, convection and conduction, with comfort being achieved by ﬁnding the balance point for the individual as they interact with their environment. In addition to the hydronic discussion, speakers also spoke in depth about plumbing systems and how they work, or should work if they are designed and used appropriately. www.opia.info

“The foundations of HRAI are strong,” stated newly minted president of HRAI, Sandy MacLeod, as he took to the microphone to introduce himself at the May meeting of HRAI’s GTA Chapter. “I think HRAI does an amazing job of delivering the programs we offer,” he said, adding that the aim is to be open to new ways of augmenting programs or delivery in the ever-changing world of business.

Scott McDonald of Johnson Controls Canada (left) discusses his company’s Verasys light commercial controls system during a break between presentations.

Seeking a single pane in IoT “When you work with multiple vendors, you get data silos,” advised Savio Lee, the Internet of Things (IoT) business manager with Ingram Micro during Yorkland Controls’ Connections Conference, held in Richmond Hill in late June. “By connecting to all of our vendors, we create a data link.” The idea, he said, is to create “a single pane of glass” through which the full building’s systems, including HVAC and lighting, can be monitored and adjusted. Lee was one of six speakers who offered insights during the event, which also featured tabletop displays and on-site experts willing to answer questions from the more than 130 engineers in attendance.

Masco Canada hosted more than 200 guests, including designers, architects and contractors, for an exclusive customer event at Quai du Cap-Blanc in Quebec City on May 15. The evening was an opportunity for guests to interact with the latest products from the company’s Delta, Brizo, Hansgrohe, Axor, Delta Commercial and BrassCraft lines, and featured the launch of Hansgrohe’s Metropol suite and Delta’s Solar lavatory and Solar ﬂush valve products. mascocanada.com

Bringing a solid history of business management skills, a long track record with associations and a joie de vivre to his new role of HRAI president, Sandy MacLeod is focused on getting a handle on as many industry issues as quickly as he can. That task is considerable, given the wide range of programs operating under the association’s umbrella, but he’s a quick study. Having joined HRAI only a handful of weeks ago, he’s also been quick to credit retiring president Warren Heeley and the association’s staff

What are some of the challenges facing the HVAC/R sector that you have started to investigate? The types of things I am hearing include environmental issues, the future of refrigerants, ongoing issues of code development and representing the industry as those changes are happening, and issues around careers in HVAC and apprenticeship ratios. There are multiple ﬁles that are very active.

I joked with people in my ﬁrst few days that I had never seen so many acronyms. I think the thing that I have been most impressed with is that people have just been wonderful.

BIO

When I left Torstar, I decided that I didn’t want to pursue media. Most of my background has been with logistics and management, I have broad business skills, and I’ve been on a bunch of boards, so I think that was the linking between the general business abilities and associations.

Strategy is as much what you choose not to do as what you choose to do. And I think that personal success is where the connection of knowledge, ambition and common sense all come together. Balancing those three things is good advice for anyone in life. When it comes to managing a team, I believe in collaboration, communication and accountability. That’s a recipe for a highperforming team.

REFRIGERATION

METERING REFRIGERANT in modern applications T

he use of electronic expansion valves [EEVs] has been growing in popularity around the world for many years, and that trend is taking hold here in North America as well, so let’s delve into some of the features of these valves, as well as why they are being used more and more to replace thermostatic expansion valves (TXVs) in refrigerant metering applications, especially with R410A and carbon dioxide systems.

How EEVs work The EEV is mechanically driven by a stepper motor that receives its drive signals from a separate control board that is hard-wired to the valve. Stepper motors offer very precise control as they can allow a valve to move in very small and equal steps. Of course, they also need to be able to reverse their direction so that a valve can both open and close. EEV manufacturers use different techniques to obtain precise ﬂow control of the refrigerant, but they all work to enable the ﬂow of refrigerant to be linearly proportional to the positioning of the valve. This contrasts with many other types of valve control techniques. A type of slider mechanism moves up or down as the motor turns. The sliding mechanism does not turn with the motor and the EEV does not use a needle and seat as would be found in TXVs. Since the valve is controlled by a separate control board or module, this gives us much more control over the valve. For example, TXVs are constant-superheat valves. However, electric valves can also be controlled via algorithms, enabling them to be used in many applications as evaporator pressure regulators, crankcase pressure regulators, hot gas bypass regulators, heat reclaim regulators, head pressure regulators, etc. There are other advantages with having a controller that is installed in a location that is remote from the valve.

Since an EEV can close off tightly, in theory it could also serve as the liquid shut-off solenoid. It is a good idea to have some alternate means for manually closing the liquid line, however, so that the system can be pumped down for service. Consider what would happen in a situation where the EEV itself needs to be serviced or replaced.

This may have an impact on the technician’s ability to adjust the superheat accurately. I should also mention that manually adjusting expansion valves in lowtemperature rooms, in the -40°C range, is not usually a lot of fun.

ACCURACY COUNTS Since these valves use a stepper motor that can travel a few thousand revolutions, it is easy to adjust the position of the valve very accurately. Each revolution results in a very small change in valve position. The temperature sensors used with electronic devices tend to be much smaller in size than refrigerant-charged bulbs, so this also contributes to a faster response to changes in refrigerant temperature leaving the evaporator. In addition to the temperature sensor, a pressure transducer is used for sensing the pressure at the evaporator outlet. The pressure to electronic transducer also contributes to a good level of accuracy.

QUICK TIP When using an EEV, the controller needs to be programmed for the speciﬁc refrigerant used in the system so that the correct superheat can be maintained. This is a very useful feature since one valve can be used in a myriad of applications.

EEVs offer the capability of operating at higher pressures. This is what enables them to be used with such refrigerants as R410A and R744. In addition to its higher pressure, CO2 refrigerant has some very unique properties compared with halocarbon refrigerants. For example, in the suction line, pressure drop has a much smaller impact on the saturation temperature. Looking at a system with a saturated suction pressure (SST) of -40°F, it takes a pressure drop of 3 psi to result in a 1°F drop in SST. With R404A, a pressure drop of 0.5 psi will produce a 1°F drop in SST. At higher evaporating temperatures, the pressure drops required to result in a 1°F drop in SST are even larger. At 40°F, it takes around 8 psi and 1.7 psi to reduce the SST of CO2 and R404A respectively. Consider a droplet of liquid CO2 at the outlet of the evaporator. There are two things that can happen that will result in the vaporization of this

groups. This is usually necessary for good control of both the subcritical and transcritical stages in this type of system.

Carbon dioxide has a latent heat that is considerably greater than halocarbon refrigerants.

Of course, EEVs can also do this, however the EEV may be a better choice in these types of situations when sized with the entire range of load in mind. Just remember that we still need to ensure proper oil travel through the system, even during low load conditions.

For single-stage systems where only one compressor and one evaporator are used, a TXV will have a tendency to overfeed during periods of low load.

In fact, it is anywhere from 55 to 68 per cent greater than R404A within an evaporating temperature range of -45° to 0°F. And CO2 has a very high solubility in polyolester (POE) oil, hence the requirement for very good superheat control in the evaporator. When installed and programmed correctly, EEVs can provide a more stable control of superheat throughout a wide range of load and high-to-low-side pressure differences.

The EEV has widespread acceptance as a very good ﬁt for applications employing CO2 but, as always, please be sure to program the controller correctly to ensure the correct ﬂow of refrigerant to the evaporator during all applicable modes of operation. When in doubt, contact the manufacturer of the valve for support. Like other controllers, an EEV will only do what it is told to do via the instructions or settings that you program into it.

Most CO2 booster systems use variable-speed drive compressors to vary the displacement of both suction

AVOIDING

PIPES

It’s summertime, so it’s warm enough that I don’t mind cracking open my archive of cold-weather stories. Keep them in mind the next time you hear someone complaining about how hot it’s been this year. Winter will be here soon enough. Enjoy the heat while you can.

THE OLD-SCHOOL WAY TO THAW PIPES Here we go again, the old bucket thawing machine is coming out to play. It’s another Friday night around 1985, and I’m stuck with Paul trying to thaw another frozen service in Bragg Creek.

Picture this: we are on an acreage that has a well or submersible pump feeding the house. The line is frozen somewhere between the pump 110-feet away and the house. Back then, there wasn’t all the new technology we have now, and we couldn’t afford a weld thawing machine – heck, we weren’t even sure if they worked – so it was the bucket method for us. The method is slow but it works. There is no water in the house except for the hot water tank, so we drain it into a bucket with a pump in it. We pull out 100 feet of quarter-inch plastic tubing and attach it to the pump. Then we slowly disconnect the compression joint on the 1” copper service valve (main water shut off) and open the line. It’s frozen, so no water comes out. Then we slowly start pushing the 1/4” plastic tubing down the service until we hit the frozen part. On this job, we pushed the tubing a good 40 feet before it came to a halt. Now we just turn the pump on and commence pumping hot water down the plastic tubing into the frozen section.

FRONT-PAGE NEWS! The winter of 1989 was one of the coldest winters that I can remember. I was thawing out sprinklers and mechanical systems for more than a week straight. The Calgary Herald even did a front-page article on my frozen pipe exploits as the weather averaged in the minus-30s for quite some time.

FEELING THE BURN

OLD-SCHOOL CON’T The tube actually moves into the frozen area, but very slowly, like a snail. It moves about 1” at a time. Being a few years younger than I am now, I didn’t care if we were getting overtime to do this tedious job, I just wanted to go out on a Friday night. Thank goodness I was working with patient Paul, who kept me there while we slowly pushed this tube down the service. It took about four hours to push it through the frozen section. All that time I was thinking there has to be a better and more efﬁcient way of doing this. And it was a good thing the home had an oversized 60-gallon tank, otherwise we’d have run out of hot water. For some strange reason, Paul waited until close to the end to let me take over. Giving me a quick lesson, he said that when you feel the tube pushing back, you pull it back quickly and rejoin the compression service valve. This seemed easy enough, but did I ever get a soaking as the water came rushing back. At the very least, he could have turned the pump off. It took me at two or three minutes to retighten the compression valve. That’s how we thawed frozen services back in the day.

When I was working service, one of the worst places in Calgary for frozen waterlines seemed to be either trailer parks or the old poorly insulated apartment buildings in the Bankview area of town. We used to work in this really old building, well, old by Calgary standards. Built around 1910, we nicknamed it Hotel California, although it was more like the Hanoi Hilton. It was chock full of cast iron drainage piping, old steam radiators, and a mix of galvanized steel, copper pipe and poly B water lines. We had all sorts of expansion and contraction problems, as a lot of the pipe was crossed between plastic, cast iron, copper and galvanized pipe without use of the expansion joints mandated by code. Most of the piping was hard to get at, but some of it was concealed in somewhat accessible shafts and crawl spaces. It was always a crap shoot to see if you could manage to isolate any of the valves, and it was almost normal to have to shut off the entire building to do a repair job. I knew this place would be a frozen nightmare if it got too cold, and sure enough, a service call came in saying several tenants were without water. Scoping out the area, I see that the boiler is on full heat, just blazing away,

Plan for cold at installation THE BOTTOM LINE IS: When living in Canada, frost will always be an issue. Pipes need to insulated, kept in interior walls and deep underground so that you don’t have to rely on a mechanical means of heat to keep them warm.

but there was so much heat loss in this building that any water pipe close to an outside wall was in jeopardy of freezing. So, I crawl down one of the pipe chases to follow the frozen water line that apparently had a heat tracer attached to it. This is where I actually learned how not to install a heat tracer. The heat tape, which was still plugged in, was incorrectly wrapped diagonally around the 3/4” copper pipe. I unplugged the wire and began thawing the line with my infamous heavy-duty heat gun. The only problem was that my heat gun kept blowing the breaker on this poorly wired building. What to do? There was at least 40 feet of frozen pipe and it was getting colder. It was time to bring out the big guns, so I ran to my truck and carried in my acetylene Big Tip Torch. It is a scary thing to try to thaw copper and galvanized piping in a tight wall pipe chase with an open flame, but this building took this to an extreme. Back in 1910, wall insulation was basically newspaper – actually a Calgary newspaper from 1910 with all the really cool soap and food advertisements from back in the day, but I had no time to read them. If just one spark from my torch fell down the newspaper-insulated wall, I would have no problem thawing the whole building. It would go up in flames like a match box. Very carefully, I managed to thaw the complete pipe and re-heat tape it properly by installing the tape flat on the pipe.

Building strong relationships A

fellow contractor recently posed these questions to me:

“As HVAC and plumbing contractors, we are one of the very few services that are regularly invited into peoples’ safest places, their homes. What is the best way to build respect and trust? What are the best practices that will have customers recommending your company to friends and neighbours?”

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.

Customer service is where it’s at By being polite, caring and helpful, you can create a customer experience that no one in your market can duplicate. It sets up the opportunity for the homeowner to give you an online review about how well you treated them. It will also keep them from falling prey to the door knockers who are just out there to railroad them into a purchase or rental of something they don’t need. With a good relationship, they will call you first.

For all of us who provide maintenance services to our customers, this question has never been more important. The fact that some of us may do the technical stuff better than others is of little concern to the homeowner unless you can demonstrate how it adds real value for them. They just want their systems to work reliably. What matters most is the relationship that gets established between the customer and the contractor. This is your only point of differentiation. We have a saying on the wall of our training centre: “No one cares how much you know until they know how much you care.” Homeowners have more options than ever these days. Your relationship is what keeps them your customer, and not someone else’s.

BUILDING THE CUSTOMER EXPERIENCE It begins and ends with communication. Are you communicating with them the way they want you to? We are finding that more and more customers want communication by email and, increasingly, text message. Texting isn’t just for teenagers; it’s for all of us. Homeowners lead busy lives. They want to know who’s coming to their home and when. Are you doing that well? Poor communication is the number 1 complaint from homeowners about service companies. It’s a good practice to confirm appointments, and email and text are great for this. Worse is the contractor who not only does not communicate, but also does not show up on time, or at all. A busy day can lead to these situations, but effective, honest communication will usually result in an understanding customer. Once you’re there, show absolute respect for the customer’s home. Ask permission for everything, including where to park your truck. These small gestures still make a huge impression on customers. Inform your customers about new technologies. Perhaps they could benefit from a Wi-Fi thermostat, or products that reduce water consumption and prevent water damage. These add value to our relationship with the customer. Ideally, we should become a “one stop source” for all things mechanical in the home even if you don’t provide the service. We maintain a referral list for other trades and make it available to all our staff.

HIGH-PERFORMANCE HVAC

IMPROVING AIR DISTRIBUTION FOR

BETTER COMFORT A

nyone old enough to remember when you ﬁrst got central air conditioning in your home? I am. When I was young, mom would say we didn’t need air conditioning, we were in Canada, after all. On hot days, she would carefully close the east curtains in the morning and then close the west curtains in the evening, we would run the summer fan, have a picnic supper in the basement where it was cool and, if all else failed, dad would take us out for a drive because he had just gotten AC in the Chrysler. When we ﬁnally did get central AC, we weren’t allowed to turn it on all the time. Mom would have us hold out as long as possible before turning it on for an hour or two to “take the edge off.” Us kids would spread out around the house feeling for the supply register that was throwing the most air and camp out over top of it for the hour. The cooling effect of moving air is one aspect of that “throw” but I want to explore the more technical aspect of the term “throw” of supply diffusers and its potential impact on air conditioning effectiveness in Canadian homes.

Gord Cooke

n i t si

i y h

Living in the historically heatingdominated climate of Canada, the logical approach to supply air diffuser location in forced air systems was at floor level. The original gravity-fed systems had supply ducts located up the centre of a home with supply grilles located in the floor to take advantage of the stack effect. The return grilles and ducts were located near exterior walls to capture the cooler air falling down the walls. As we transitioned to forced air systems, supply diffusers were

moved to “bathe” exterior walls and windows in an attempt to warm up those surfaces and improve comfort. Return grilles were moved to interior walls or central locations for convenience. The HRAI Digest, the most commonly applied design guide for residential duct systems in Canada, suggests locating supply outlets in heating only systems, so as to “bathe at least one exposed wall or window with warm air.” It goes on to say when choosing the supply diffuser to compare the “spread and throw of the diffuser at 500 feet per minute with the length of exposed wall” to be blanketed.

SPREAD: The divergence of the airstream as it leaves a diffuser.

M e c h a n i c a l

THROW: The distance from the centre of the diffuser to a point where the velocity of the air stream is reduced to a specified velocity.

In a typical residential floor supply diffuser, the spread would be the distance the air is thrown horizontally away from the diffuser. In a residential system, the throw would be the vertical distance up the wall the air travels. In residential applications the throw distance is measured at the point where the velocity has dropped to 50 feet per minute (FPM). This is called the Terminal Velocity. That velocity is used because it is the point at which occupants typically start noticing a draft effect.

COVERING ALL THE ANGLES It should be possible to get the technical data showing the spread and throw of residential diffusers. This chart shows select data from two diffusers from the same manufacturer; the difference is simply the angle of the diffusion vanes. Notice the difference in the spread and throw at 500 FPM. Above diffuser B you could expect to feel cool air up as high as 8’ if the air volume exiting the diffuser was 85 CFM (cubic feet per minute), whereas with diffuser A your clients might complain that all the cool air

spills out near the floor and only their feet feel cool. Notice, too, how quickly the throw drops at the lower velocities when there is less airflow at the diffuser. At 300 FPM, when the diffuser is only seeing 50 CFM, both diffusers have a throw below 4’ and it is unlikely either one will satisfy the cooling needs of your clients on a hot summer night. This is a very important consideration in newer homes where heating and cooling loads are much lower because of better

better air conditioning performance to your clients. Add more thought to the selection of diffusers to the tools you have to satisfy the ever-increasing expectations of your customers for greater comfort There are choices available to increase the throw of cool air to get control summer and winter.

Cooling changes things

STUDYING THE THROW Since we were ﬁnding it difﬁcult to get full technical data on commonly available residential diffusers we decided to build a simple test rig in our shop so we could measure and feel the performance. We bought and tested 13 different diffusers, including a couple of the highly decorative metal “designer” patterns and a wood grille. We also had a commercial grade diffuser with airfoil type blades in a 4” x 10” format.

Because of the natural buoyancy of warm air, supply diffusers in heatingonly residential applications were typically manufactured to optimize the spread of air to bathe inefficient exterior walls and windows.

The picture shows my partner Rob measuring the velocity at the 5-foot level of our test rig. We did measurements at two different airﬂows, 60 CFM and 110 CFM, using the very accurate Energy Conservatory DuctBlaster. This represents face velocities of approximately 350 and 550 FPM. The duct supplying the diffusers was 6” diameter and had a standard angle boot to 4”x10” at the end. The duct and ﬁtting were properly air sealed. The measurements were done with the diffuser dampers fully open.

When you add a cooling function to a duct distribution system it is desirable to optimize the vertical throw of cool air to ensure proper mixing of air throughout the occupied zone, especially on the second floor.

Here are some highlights from this fun little project.

Notice how well the airfoil blades of the more commercial type diffuser do at maintaining the velocity. There are other advantages to these better diffusers as well. They had a gasket around the base so it fit snugly into the boot, so there was no chance of air sneaking by the diffuser into surrounding carpets. If a diffuser has adjustable blades and a double deflection format this would mean you could adjust airflow patterns for summer and winter or for specific location needs.

Light at the end of the insulation? Not long before press time, Canadian Hydronics Council chair Dave Hughes dropped me a line to let me know that a solution is in the works for the underslab insulation conundrum that has been plaguing the hydronic industry in Alberta. For those not familiar with the issue, in November of 2016 that province began enforcing Section 9.36 of the National Energy Code for Buildings, which has been adopted into the province’s energy code. Included in Section 9.36 is a provision for R-16 underslab insulation, or roughly 3.5 to four inches of insulation. That’s a signiﬁcant increase from the one inch of insulation listed in CSA B214, the installation code for hydronic systems, and it’s proven to be a barrier to inﬂoor heat installers.

Catch up on training The Canadian Hydronics Council is holding its 2018 education conference during the CIPHEX

West show in Calgary. Visit It was noted by CHC members during the ciphexwest.ca for more details. recent Canadian Hydronics Luncheon that the hydronic segment in Alberta has been decimated by the change. Adding to the pain is the unintended consequence of driving home builders to other, less efﬁcient heating options that do not have a requirement (and associated costs) of underslab insulation. While currently contained to Alberta, the issue, warned CHC, is one that could emerge in other parts of the country as well, since Section 9.36 is part of the national energy code.

We acknowledge the support of the Government of Canada.

But there appears to be a light at the end of the tunnel, at least for Alberta. CIPH and CHC are reporting that a Standata Interpretation is in the works that will allow for radiant heating to be installed without the R-16 insulation requirement in Alberta. A proposed code change, a solution, if you will, will be presented to the Provincial Territorial Policy Advisory Committee on Codes, which will allow for ot other provinces and territories to navigate the issue. It’s been a long road for hydronic installers in Alberta, but the regulatory bod bodies do appear to be open to an industry-proposed solution, and w we are looking forward to the Standata seeing the light of day soo soon. I’m sur sure that those of you attending November’s Can Canadian Hydronics Conference in Calgary will have plenty to talk about. p Until then,

GUEST COMMENTARY

Dave Hughes is the chairman of the Canadian Hydronics Council and associate chair (special projects) of pipe trades at NAIT. He can be reached at dhughes@nait.ca.

Growth through education

his has been an exciting year out where I live, here in Alberta. The insulation issue that’s been plaguing our province, and the rest of the country, may have just been successfully resolved, but that’s just one of many stories that are always on the go in this hydronic sector of ours. Much like there is a need to share credible information about the sub-slab insulation concerns, there is also an ongoing need to provide valuable professional development opportunities to hydronics installers and designers, regardless of where they work in Canada. One of the main drives for the Canadian Hydronics Council (CHC) is continuing education. Under ideal circumstances, CHC would like to see all hydronics designers and installers in Canada certified – I understand that this would be quite a feat, but we have to have a goal to aim for. Certification is always our end goal, and there are many means of getting there. In addition to the full training offerings at Fleming College in Peterborough, Ont., and NAIT in Edmonton, one and two-day courses using individual blocks from the certification materials have been offered in many areas across the country. These sessions build upon each other and can be used to gain enough knowledge to challenge for certification. This November’s Canadian Hydronics Council Conference is also a prime example of the training opportunities that exist from CHC, and it’s one that I’d like to invite you to take part in. This upcoming event, which will be held at the same time as the CIPHEX West show in Calgary, will feature some of the best speakers in the industry and is quite simply one of the best opportunities to expand your hydronic knowledge this year. To register, hit the CIPHEX West 2018 website, www.ciphexwest. ca, and then click on the Visitors information menu tab. We look forward to seeing you in Calgary!

Planning for Foothills 2.0 As a council, CHC is continuing to work on perfecting the format of our conferences, and we want to enable training sessions to be moved across the country. Currently, the CIPHEX shows have been our only vessel to bring this important service to other areas of Canada, but we are working on expanding our reach. Using a working title of Foothills Version 2.0, the 2019 rendition of the CHC Hydronics Conference is planned as a standalone event that will be held in October of next year, in Ottawa. The event will be modelled after the Alberta’s Foothills Conference, which some of you may recall or may have even attended. Like Foothills, this conference will offer two days of sessions with ample opportunities to visit vendors between sessions. The 2019 conference committee is currently being assembled, so watch for details, or join in the planning. If you are in the Ottawa area and interested in helping to plan this event, please contact me at dhughes@nait.ca.

WE’RE GONNA NEED A

bigger pump B

ack in the days of gravity-hot-water heating, before we used pumps, a contractor would install big pipes to keep the resistance to flow to a minimum. The boiler would heat the water, which would flow languidly toward the radiators, nudging the colder water that filled the pipes and radiators above the boiler downward. If the contractor followed the rules of gravity-heat piping, the big wheel of water that is a hydronic system would turn like a ferris wheel and the customers would say, “Ahh!” Then 1928 arrived, and with it came the simultaneous introduction of the hot-water circulator. Within days of each other, Homer Thrush introduced his Thrush circulator in the United States and Louis Opländer did the same in Germany with Wilo. Let’s hear it for paradigm shifts. These circulators sped up the water that flowed in gravity systems and, when combined with a flow-control valve, gave the contractor a way to control the flow of hot water between a boiler and the radiators by having one of those newfangled thermostats start and stop the circulator. Those early circulators were able to move a lot of water against a relatively low resistance to flow because the pipes in a gravity-hot-water system were deliberately large to keep the resistance to flow at a minimum. The Dead Men didn’t need much of what we came to call “pump head” in those days. They did, however, have to get used to the fact that pump head didn’t refer to the height of the building, but rather to the resistance to flow as the water flowed around the big loop.

Homer Thrush introduced his Thrush circulator in the United States and Louis Opländer did the same in Germany with Wilo. The height of the building doesn’t matter because the weight of the water going up balances the weight of the water coming down. Think about the motor on a ferris wheel and you’ll understand how a circulator really works. The circulator isn’t lifting; it’s turning. Fast-forward 20 years to around 1948 and we now see packaged boilers. The circulators that came with those early packaged boilers all had the ability to move a relatively large ﬂow against a relatively low head. Larger pipes were the still the norm in those days, and all of those early circulators ran on 1,750rpm motors. Their ﬂow versus head performance curves were nearly identical, regardless of the manufacturer.

Which brings us to the 1970s and the birth of smaller, water-lubricated circulators. These ran at much higher speeds, used less power and cost less to buy. They soon replaced the 1,750-rpm, oil-lubricated circulators that had been on packaged boilers. Things started to get interesting when the little circulators wound up on packaged boilers that ranged in size from small to pretty darn big. And since the boiler manufacturer was providing them, many contractors began to think in terms of one-size-ﬁts-all when it came to the tiny circulators. And that led to problems. Years ago, someone sent me a photograph of a rather large boiler with a thick pipe

leaving it. The pipe teed into a manifold that fed 15 zones using 3/4” pipe, each with a zone valve. The circulator in use was one called Little Red, and that circulator was indeed both little and red.

Circuitous thinking Back in the ’80s, when hydronic radiant heating was catching the attention of contractors, a guy called to ask what size circulator he needed.

º7 >Ì Ã ÀÌ v L Ã Ì¶» >Ã i`°

In his letter, he explained that all was ﬁne when running just a few zones but trying to run all 15 zones at the same time ended up with most not getting hot. So, he asked, “Do you think the boiler is too small?” I told him he was gonna need a bigger pump, one that could move more water because that’s what this job needed.

Pumps in series

TAKE CARE IF YOU REMOVE A RADIATOR Bell & Gossett called them Monoflo Tees. Taco called them Venturi Tees. Nibco even had an insert that would turn a standard tee into one that could divert water out of main into a branch that ran to a radiator. Whatever you call them, they all work in a similar way. The small cone that’s inside these tees adds resistance to flow along the main. When water feels that resistance, some of the water will decide to travel into the branch piping instead of staying in the main. That’s how the radiator gets hot. There are rules you need to follow with these special tees, such as making sure you place the tees the width of the radiator apart if the main is higher than the branch piping. Another rule is that if you disconnect a radiator, you also have to either remove the special tees, or you have to connect the piping that used to feed the radiator or convector from the special tees with a small piece of pipe. If you just cap the branch lines, all the water now has to squeeze through the narrow openings within the special tees. And since you can’t compress water, there’s going to be a lot more pressure drop. It just may be enough to stop the flow altogether. To a circulator, pressure drop can feel like a closed valve. You’re gonna need a bigger pump. Learn the rules and follow them.

A mechanical magician Ever have one of those installs where things fit, in theory, but you’re the one who has to figure out how to make it happen in real life? Colin has. Faced with a customer who wanted to install a boiler in a void space below an addition that was built on top of an in-ground pool, he had to figure out how to get the boiler and the other system components into one of the smallest mechanical rooms he’s ever had to work in. “Access was through a door in the floor, and my apprentice was 6’3”, so he couldn’t even fit down there. “There was not enough space to stand up, and you couldn’t lie down either as you would slide down the pool’s sloped floor,” he said, reflecting back. “It was a small install, but it still had a four-way mixing valve for in-floor heating, a heat exchanger, domestic indirect tank and an air-handler coil.”

Watch the mounting position

Check valve installation options vary quite a bit. Some swing checks can be used either in vertical or horizontal position, but not all of them. Choose spring or weighted checks for hydronics. Swing checks need a pressure differential to seal tightly. Pressure relief valves for boilers need to be in the vertical position, but water heater T&P valves are installed in a horizontal or vertical orientation. The sizing of relief valves is crucial also; itâ&#x20AC;&#x2122;s not just about the pipe size!

WORKING IN PAIRS In many cases, two valves piped in parallel is a preferred method to one single, large, higher cost valve. Take thermostatic mix valves, for example. Two smaller valves will help provide the maximum ďŹ&#x201A;ow rate required, but also have better stability at low ďŹ&#x201A;ow rates. High Cv mix valves tend to need up to 5-gpm minimums to give accurate

mix temperatures. A small sink draw can result in a â&#x20AC;&#x153;threadâ&#x20AC;? temperature as the valve struggles for resolution. Two smaller Cv valves in parallel can provide high and low-end accuracy. With a pressure reducing valve (PRV) you can apply the same concept. Two 3/4â&#x20AC;? PRVs in parallel could replace a larger, more expensive valve.

PROJECT PROFILE By Denise Deveau

DREAM HOME LOTTERY PROJECT PUTS

snowmelt on show W

hen it comes to hydronic floor heating, and snowmelt systems, Paul McRoberts, owner and president of iFH Designs in London, has had plenty of practice. He’s been installing systems for more than two decades. Despite all those years in the field, he says not that many people know about them, and what hydronic heating will do. “Even though I’ve been installing systems since 1992, a lot of people are still learning about these systems, plus we still find that we have to educate customers asking about floor heating and snow removal systems.” He recently had a chance to educate the public in a big way when iFH designed and installed hydronic snowmelt systems in two Dream Home Lottery homes in the new Baseline-Byron development project in London, Ont. This wasn’t the first rodeo for the team. They also installed snowmelt systems in more than a dozen other

Project in Numbers

Continuing a relationship homes in the same community. In some homes they also added in-floor heating. McRoberts says he was grateful for being able to work on the Dream Homes, because it gave hydronic systems a boost in the public eye. “It was a big highlight as these were the first two lottery homes that had heated driveways. This is helping us educate the public, and maybe some builders, that they should be looking at this heat as the most inexpensive on the market to heat your home, office, hospitals, etc.” He says that while the installation cost of a boiler may be higher than a regular everyday furnace, there is no comparison on the heat side when it comes to comfort. “Plus,” he says, “the savings will offset the costs over seven to 10 years. In my mind, it’s a no-brainer.”

Hydronic Snowmelt System Installation Tips

1 2

Building the systems Every system has its own challenges and workďŹ&#x201A;ows. For these two builds, Millstone Homes prepared the levelling of the driveway, the forming of the steps, and the front porch area.

Make sure the R values on your insulation are correct. â&#x20AC;&#x153;We always use an R10 value,â&#x20AC;? McRoberts says.

â&#x20AC;&#x153;The front porch was done ďŹ rst, so we installed the 2â&#x20AC;? panel insulation and half-inch oxygen-barrier tubing on six-inch centres,â&#x20AC;? outlined McRoberts.

Check the spacing and length of piping. â&#x20AC;&#x153;Spacing and length of loops is critical,â&#x20AC;? he says. His preference is a nine-inch spacing from centre-to-centre, and a maximum loop length of 300 feet for 3/4â&#x20AC;? piping. â&#x20AC;&#x153;While shortness is not a problem, if your pipes are too long, the heat wonâ&#x20AC;&#x2122;t get to the last part of your loop.â&#x20AC;?

Once the stairs were framed, they installed the remaining insulation and 3/4â&#x20AC;? piping on nine-inch centres, to complete the laneway, walkway and step areas. They then installed two four-inch standard dimension ratio (SDR) pipe sleeves under the heated slab in the garage that ran into the basement near the boiler room. The lines were then pulled into the basement and connected to an eight-station manifold system.

Always use oxygen-barrier piping. Any oxygen that gets into the heating system can cause components, like cast iron pumps and other metal components, to rust.

The work on the two lottery Dream Home properties was completed in the spring of 2018. At that time, the weather was still on the cold side, so McRoberts and his team needed to use heated blankets to keep the frost at bay.

Ensure that the pump selected is sized appropriately for the flow rate. â&#x20AC;&#x153;This is critical,â&#x20AC;? says McRoberts. â&#x20AC;&#x153;You donâ&#x20AC;&#x2122;t want water moving too fast because it doesnâ&#x20AC;&#x2122;t allow enough time for the slab to grab the heat.â&#x20AC;?

Always add glycol to outdoor hydronic heating systems. McRoberts uses a non-toxic propylene vegetable-based glycol.

Installation of the insulation and tubing, including the manifold and pressurizing the system with air, took about two days. Of course, now that everything is up and running and fully automated, the systems are ready to do their job. â&#x20AC;&#x153;Once the snowďŹ&#x201A;akes hit the sensor, it will turn the system on.â&#x20AC;? While each hydronics project is unique in its own way, McRoberts says, â&#x20AC;&#x153;This one stands out because we had a great group of employees who understood what was needed, put their heads together, and got the project done.â&#x20AC;?

Covering the DHW, too

A responsive system A key reason why hydronic systems were selected for these homes, says McRoberts, is the energy savings and the short time needed to remove snow and ice over other snowmelt options. â&#x20AC;&#x153;When you think about those two things, it made the decision pretty easy.â&#x20AC;?

Equipment List

In addition, he says that snowmelt systems are a great selling point for contractors. â&#x20AC;&#x153;The safety factor is important. No ice to slip on. No snow to shovel. Overall itâ&#x20AC;&#x2122;s a healthy way of removing snow.â&#x20AC;?

â&#x20AC;&#x153;What really stands out for all the installations is the boiler that was installed, which also takes care of all the domestic hot water use,â&#x20AC;? McRoberts says. By adding a circulation pump on the last hot water outlet, homeowners can have a seemingly endless supply of hot water without waiting for it to reach the taps. â&#x20AC;&#x153;Thereâ&#x20AC;&#x2122;s no waste.â&#x20AC;?

HVAC TOOLS By M a r k Pa r l i a m e n t

THE

RIGHT TOOLS CAN MAKE ALL THE DIFFERENCE

If you are not installing air conditioning units, you’re maintaining these machines, which means ensuring that you have the right tools for the tasks you’ll be performing for your customers. Thankfully, tool choices are plentiful for our sector, but there are a number of “must-have” tools that I turn to, since they are designed for ease of use, comfort and accuracy – and ultimately make the task of installing and maintaining this mechanical equipment much easier. And please note, while you’ll see a number of my tools in these pages, I am not beholden to any particular brand of product on the tools front, but quality is important, so I tend to stick with some of the better-known brands out there when it comes to equipment that I need to be in calibration with good precision and accuracy.

CHECK THE FLOW Before beginning any maintenance on the air conditioning system, it is important to gain a proper understanding of the total system performance. To properly evaluate the system, the first test to run should be for proper airflow. Without knowing the proper airflow, we cannot be sure that subsequent readings are accurate, no matter the brand or make of tool we use. After all, garbage in (incorrect readings) equals garbage out (incorrect troubleshooting). By using a manometer and static tips after the filter and before the air conditioning coil, you can see the external static pressure that the air mover (furnace or air handler) is being subjected to on the duct system. By consulting the manufacturer’s blower performance charts, you will be able to see the exact CFM that is being pushed across the coil. Once you ensure that the system is seeing the proper airflow, you can then move on to a more in-depth diagnosis of the system.

HOW MUCH HEAT? The next step is to calculate the enthalpy. Air conditioners are designed to remove enthalpy (total heat). Without knowing how much total heat the air conditioning unit is removing, there is no way to know if the system is doing what it is designed to do. A digital psychrometer placed in the supply and return gives us both wet bulb and dry bulb readings from the air stream. By comparing these readings to the psychrometric chart, we can then be able to surmise the system’s enthalpy. The difference in the readings between the supply and return of the unit equals the total heat, or enthalpy, that is being removed from the system.

WHAT’S THE AMP DRAW? Another important factor in understanding the performance of the overall system is to learn the amp draw of the PSC motor (and this is really what a compressor is). This will help you see the amount of work that is truly being performed by the compressor. By clamping on the common wire with a digital clamp multimeter, we will be able to read the current draw of the compressor and compare it to o the current draw of the system. A compressor that has a very low ow amp draw is technically not doing oing any work. This is a possible indication of a system that is undercharged. On the opposite side of the spectrum, a compressor showing a very high amp draw is a warning that the compression is working hard, and that you may have an overcharged system.

Once we know the correct airflow readings, enthalpy and power consumption, we can get a more complete picture of how the air conditioning unit is performing, and that information can now be used as a starting point to troubleshoot the system. One of the most common customer complaints is temperature fluctuations throughout the house. You may, for example, find a change in airflow between seasons. There could be uneven airflow during the summer months while air circulated

HOOKING UP THE MANIFOLD

EVENING OUT THE AIRFLOW perfectly during the colder seasons. Since humid air is heavier than dry air, it is harder to move through the system, and this could cause uneven airflow once the outdoor temperatures rise. A rotating vane anemometer can be used to read the velocity and air volume and to measure unevenly distributed or fluctuating throws through the cooling coils, extract grilles and registers. Placing the rotating vane anemometer in the air stream as the air exits the register or grille will measure the airflow and calculate its speed. Using the grille manufacturer’s data, you can then calculate the throw of the register to ensure it is throwing far enough into the room to get a good enough mixture in the air before stratification.

One of the final things to do in the diagnostic sequence is to hook up a gauge manifold to the air conditioning system. Sadly, this is often one of the first things technicians do, which can create incorrect readings on all subsequent tests. This is because any time a conventional hose and dial type manifold is hooked up, there is a small amount of refrigerant removed from the system. A system that was properly charged at installation could quickly become undercharged from all the hose connections and disconnections completed during a maintenance visit. The nice thing about hose-less and wireless manifolds is that almost zero refrigerant is lost during a hookup. Some digital manifolds even come with clamp-on temperature probes and airflow thermostats that will make a technician’s life very easy when calculating things like superheat, subcooling and temperature drops across a coil. Gone are the days where a technician had to do manual calculations to learn what a system is running for superheat or subcooling. With the proper connection of the clamp-on temperature probes and insertion of the airflow temperature probes into the ductwork air stream, the digital gauges will make all the calculations for you.

CELEBRITY ENCOUNTER By Adam Freill

He shoots, he scores? For most Canadian kids, playing ice hockey is a rite of passage, but a young Wickens found go-karting the fall before he was going to play his ﬁrst year of Timbit hockey. “My parents asked me if karting was what I really wanted to do, saying that if I wanted to do that, I wouldn’t be able to play hockey with my friends,” he recalled. “I’ve actually never played in a hockey league,” he said with a laugh. “I have played shinny, and I was in a ball hockey league until I moved to Indianapolis. Hockey is still one of my passions and is my second-favourite sport to motorsports, but I opted to take a different path.”

“My career would have never happened if we had to pay a mechanic to work on my karts. The fact that I had my brother and my dad there all the time was just awesome.”

or race car driver Robert Wickens, when it comes to motorsports, it’s a family affair. The native of Guelph, Ont., is in his first full IndyCar season, but he’s no stranger to racing. His path to the IndyCar cockpit has been long in the making, and he’s not one to take things for granted. He and his family have worked too long and hard for that. Wickens’ first exposure to racing was through the Waterloo Regional Kart Club in 1997. It wasn’t long before he was winning series championships. At 16, he started his formula racing career, racing extensively in Europe for the next 12 years, picking up numerous podium finishes and a pair of series championship wins along the way. Prior to the start of the 2018 IndyCar season, Wickens joined his best friend, and fellow IndyCar driver, James Hinchcliffe on the Schmidt Peterson Motorsports team, and it’s been a strong debut season.

All in the family; All for the family

Friends, on and off the track

Robert Wickens describes his family as pretty average, as far as Canadian families in Southwestern Ontario go. His father was a mechanic in a factory and his mom drove a school bus, and when it came to fostering their son’s passion for motorsports, they did all that they could to support him. “Ultimately, I guess they saw my potential and how happy racing made me, and they would do anything they could to allow me to live my dream. They are the hardest working people I know.” Wickens doesn’t hide the admiration that he holds for how much his parents did to allow him to race, and his gratitude also extends to his brother, Trevor, who took a part-time job working at a local kart shop to earn parts and tire credits for his race weekends. “The amount of sacriﬁce that they gave in order for me to be able to live my dream is something that I will be forever grateful for and forever trying to pay them back for,” he said. “If it wasn’t for them, my racing career would have lasted two years.” He and Trevor, who is now one of the most highly respected karting coaches and tuners in Canada, would ride their bikes to a local kart shop after school and work there from 4 until 9 p.m., go home, do their homework and then go to school the next day. “That has made me the driver that I am today,” said Robert. “I feel like I have never taken anything for granted. You need to work hard for everything.”

An early start Wickens doesn’t really know why racing clicked for him, but he’s glad that it did, and that it pretty much found him at an early age. “From what I have heard, I was a bit of a brat when I was a kid,” he laughed recalling his introduction to fast cars. “I got a toy car that I just loved and from that point on, if there was a Formula 1 race on TV it was like I was hypnotized by the race.” His parents would record races on VHS tapes, and would play them for him during the week. “Kids would be watching Barney or Sesame Street, and I would be watching last weekend’s Formula 1 race,” he said. “And then I would re-enact the race with my little toy cars and my carpet race track.”

DID YOU KNOW?

This year’s racing season isn’t the first time that Wickens has paired up with fellow Canadian James Hinchcliffe. The two have been best friends for over a decade, first meeting at the kart track when Robert was 12 and Hinchcliffe 14. “We were racing for the same team in karting,” said Wickens. “We just hit it off. We became good friends instantly.” What started off as hanging out at the racetrack soon turned into hanging out away from the track as well. “We have kept a very strong relationship our whole lives even though our careers went in very different avenues for a while,” he shared. “We stayed in very close contact, and now it is super cool that we both get to race Indy cars alongside each other.” Knowing each other so well, and having similar formative years, has been a big plus for the team. They both like a similar setup to their cars, and approach driving in much the same way, but that doesn’t mean that there’s no fire to win when the two hit the track against each other. “We’ve always had a very friendly competitive relationship. In karting, James would go and do a lap time and I would go ‘Oh yeah?’ and go out and up the bar, and he would go out and up the bar. It was constant; never ending,” said Wickens. “We kept pushing each other our whole childhood, and it obviously made both of us better drivers. It is the same thing in IndyCar.”

James Hinchcliffe was the May/June 2013 Mechanical Business cover celebrity. You can ﬁnd that article in our back issues, available online at www.mechanicalbusiness.com.

Finding the podium at home Racing in the only Canadian stop on this year’s IndyCar schedule, teammates Wickens and Hinchcliffe thrilled the local fans, ﬁnishing third and fourth, respectively. For Wickens, this was his third podium ﬁnish and ninth top-10 result in his rookie season in the series.

“Thankfully, I’m not an overly teary guy, but that was really cool,” he said of the ovation he received from the hometown crowd when he stepped out of the car. “To stand on the podium in my ﬁrst professional home race, I couldn’t ask for anything better.” M e c h a n i c a l

TACKLING TANKLESS

DHW Gas Supply

Tankless water heaters will typically use higher gas quantities than their tank counterparts to meet a sudden demand for hot water without storage, so the installer must ensure that the LÕ ` } >Ã ÃÕvwV i Ì }>Ã «ÀiÃÃÕÀi Ì meet all the building’s gas needs.

ith a long history of use in Europe and Asia, tankless water heaters have been making signiﬁcant inroads in North America over the past several years. As more and more plumbers are installing this technology, the need for proper installation guidelines is becoming greater than ever. Installers accustomed to tank-only installs need to understand some of the things that make tankless water heater installations different from storage-type water heaters, and how these can impact the selection, installation and maintenance of these units.

Once the gas meter’s capacity is V wÀ i`] Ì i }>Ã i ii`Ã Ì Li adequately sized to supply enough gas to the water heater. A typical tankless water heater will need a 3/4” gas line, LÕÌ v Ì iÀi Ã ÃÕvwV i Ì «ÀiÃÃÕÀi > ` the run length is short enough, it may be possible to use a half-inch line, which is used by most existing storage tank-type water heaters. But be sure to account for all the appliances using this line, not just the water heater, and verify gas requirements and sizing with local licensing rules and codes.

Neutralizing the condensate for drainage

Let it breathe Like any combustion appliance, gasfired tankless units need a sufficient amount of incoming air for the combustion process to operate properly. The size of the openings for combustion air — from indoors or outdoors — is based upon the tankless unit’s BTUH input.

If the heater draws combustion air from the surrounding indoors, one square inch of combustion-air opening is needed for every 1,000 BTUH of the appliance. If the heater draws air from the outside, the openings required are at a rate of one square inch per 4,000 BTUH.

PICKING THE RIGHT SIZE The type of tankless water heater chosen for any given application will depend on incoming water temperatures and building use patterns. The temperature rise between the desired hot-water temperature and the incoming ground water temperature will indicate how hard the water heater must work to provide hot water for the application. Incoming ground water temperature can be measured directly or estimated by a knowledgeable professional, but for sizing purposes, the typical worst-case scenario (the middle of winter) should be assumed, to ensure adequate hot-water availability year-round.

Table 1: Approximate Fixture Flow Rates

To maintain the proper flow to meet the simultaneous DHW needs of the entire building, it’s important to calculate the amount of hot water typically used at any given time, or the peak amount that could be needed. To do this, count the quantity of fixtures of each type (dishwasher, shower heads, etc.) and then multiply each of these numbers by the flow rate of the respective fixture. Table 1 displays a list of common fixtures and some approximate flow rates.

4.0 GPM

Shower

2.5 GPM

Washing Machine

2.0 GPM

Dishwasher

1.5 GPM

Kitchen Sink

1.5 GPM

For example, if a building has three ﬁxtures: one shower with a ﬂow rate of 2.5 gpm; a washing machine, at 2 gpm; and a handwashing sink, at 0.75 gpm, the total demand to meet is 5.25 gpm.

Finally, calculate the sum of all these ﬂow rates as if all the appliances were operating simultaneously. The tankless water heater must be able to deliver this maximum ﬂow rate at the desired temperature rise.

For residential applications, the hot water set point temperature should only be slightly above the highest temperature needed for domestic uses. Shower temperatures are usually between 104°F and 106°F, so a tankless water heater should rarely be set above 115° to 120°F. Scalding is more likely to occur when temperatures exceed 125°F, so it is generally not recommended to set the water heater higher than this. Since tankless water heaters do not store any hot water, they are not susceptible to L>VÌiÀ > }À ÜÌ ] > ` Ì iÞ V Ì Õ ÕÃ Þ yÕÃ any internal water with every use, so there is no sanitary reason to maintain a high set point temperature.

Water quality is an important consideration for all water equipment, and especially water heaters. Of particular note is water hardness, which is a measure of the minerals, mainly magnesium and calcium, it contains. When heated, these minerals can precipitate out to form limescale. This coats pipes and acts as an ÃÕ >Ì À] Ài`ÕV } i>Ì ÌÀ> ÃviÀ ivwV i VÞ > ` increasing thermal stress, which can ultimately reduce the water heater’s lifespan. As such, scheduled maintenance should include descaling of the water heater’s heat exchanger coils.

What’s cooking

in that kitchen? F

or this edition of Quattro’s Corner, I’m taking you behind the scenes of a restaurant’s kitchen, a small kitchen, but a kitchen nonetheless.

Throughout my years of inspecting, I have found that commercial kitchens tend to cause the most problems for plumbers. Multiple compartment kitchen sinks, required handwashing stations and the dreaded indirect connection can complicate things. Most would think the requirements for fixtures in commercial kitchens would be found in Part 7 of the OBC or National Plumbing Code of Canada but look for other sections where this may be covered. For example, in the Ontario Building Code most requirements are found in Division B Part 3, specifically 3.7.6. Food Premises (Ontario). This section outlines the minimum requirements for fixtures, the location of fixtures and room finishes. To paraphrase that section, if utensils are to be cleaned, there’s a need for a three-compartment sink, three sinks or, with specific caveats, a two-compartment sink or two sinks. A separate handwashing sink is also required, and must be in a convenient location for employees.

Don’t forget your cleanouts We always seem to miss cleanouts, and they are required in so many locations, especially at changes of directions and kitchen sinks.

The sink setup in the photo appears to meet the basic code requirements, but let’s look deeper.

What’s wrong The trap serving both the handwashing station and threecompartment kitchen sink is not permitted, as per section 7.4.5.1 (2) of the OBC and 2.4.5.1.(2) of the NPC. Looking at the fixture outlet pipe of the hand washing station, I see trouble there as well. OBC section 7.4.8.2.(1) and NPC section 2.4.8.2.(1) state, “…the developed length of every fixture outlet pipe shall not exceed 1,200 mm (1.2 m).” Clearly the distance from the handwashing station to the trap on the three-compartment sink exceeds this requirement, not to mention that no clean-out is installed. Both the OBC and NPC state that the part of the fixture outlet pipe common to three compartments of a sink needs to be a size larger than the largest fixture outlet pipe of the compartment it serves. This sink has a minimum 1-1/2” fixture outlet pipe and a hydraulic load of 1.5 per compartment or bowl.

M e c h a n i c a l

B u s i n e s s

In Ontario, Table 7.4.10.7 lists a maximum load of 4 fixture units for a 1-1/2” pipe. The NPC lists a maximum load of 3 fixture units for that size drain. The trap and the connection at the third compartment should have been increased to 2 inches in size and the hand-washing sink should have been separately vented and connected separately to the drainage system. Wow! Who would have thought that what looked like a good install could be wrong in so many ways? Sometimes it can be difficult to remember all the different requirements and where to find them in the Building Code.

Marketing Building an effective campaign If you’re convinced radio is worth looking at, the next step is to build an effective, creative campaign. Not all radio ads are created equal, and there are a few things to keep in mind when conceiving your concepts cep epts ts or writing scripts. The ﬁrst is to keep it simple. T Thirty h rt hi rtyy seconds goes quickly, and the mo most ost st common mistake is to write a scriptt that says too much. One clear fact or message, followed by a call-to-action, should be your goal. Remember that you can record several commercials to run in a campaign. Spread your messages across them. Think carefully before accepting the station’s offer to have a local announcer record the commercials for you. This risks you blending into the audio wallpaper. Professional voice readers are easy to come by. Voxcanada.com is a great website to source actors, and the costs are surprisingly low. As little as $300 or so should get you what you need. If you’d rather record them yourself, that’s ﬁne, provided you’re providing advice and not just extolling your virtues – and, that you’re actually pretty good at it. We’ve all cringed at the commercials with business owners who just needed to hear themselves on the radio (or their kids – no, no, no). Jingles work. Think Sleep Country Canada. Guaranteed, 9 of 10 readers now have that jingle stuck in your heads (you’re welcome). A small investment with a local musician or studio should need a great result that can last for years and become an iconic local advertising story.

raditional advertising has a bit of a bad rap these days. Television? Expensive to produce and run, and who’s watching TV anymore? Newspaper? The smaller ones are being shuttered, and the bigger dailies are struggling. Magazines? Specialty trade publications (like the one in your hands) have maintained a foothold because of their highly targeted and qualified audiences, but consumer publications are searching for readers amidst a sea of bloggers. There are plenty of reasons to carefully scrutinize old-school marketing, however if we include radio in the “that was then” category, there is a risk of throwing the baby out with the proverbial bathwater. Local radio listenership is doing just fine. According to Statista.com, radio listenership in Toronto jumped three per cent between Summer 2016 and Spring 2018 and is holding steady in most markets. The Broadcast Research Council of Canada reports 90 per cent of Canadians listen to the radio, and two of every three daily commuters favour radio stations over streaming services or listening to music on personal devices. Canada Radio Media, a specialty radio advertising agency, says Canadians listen to the radio an average of two-and-a-half hours daily, so it appears that radio is weathering the digital storm just fine. The strongest demographic is 35-to-54-year-olds. With families relying on school bus reports, retailers piping radio to shoppers, and a strong culture of giving back to the community, local radio has remained one of the most intensely local and reliable sources of news, weather and information for Canadians. That makes it an ideal place for HVAC and plumbing contractors to reach homeowners.

A good buy I’ve liked smaller-town radio for its relative affordability (less so in large urban markets, but still good value), for the freedom it allows to be creative and playful, and especially for its versatility. On a reasonable budget, you can build a strategy that includes some or all of the opportunities outlined on page 82.

A. O. SMITH COMMERCIAL TANKLESS RACK SYSTEM

Standard advertising in 30 or 60-second spots (I say with current attention spans, stick with 30s). One trick: pulse the campaign to stretch your budget – every few days take a break or reduce the frequency.

Prizes and promotions. Morning show antics usually mean they’re looking for prizes and giveaways. A gift basket of swag is a start, but also consider a high-end rain shower head, or a digital thermostat.

Remote on-site engagement. Most radio stations have their “remote on wheels” and can arrange a live broadcast or segments from your business. This is ideal during a time-intensive promotion or community event.

Share your expertise. Depending on the station, business owners can arrange for some on-air time to provide listeners with valuable tips and strategies for their homes. Some have weekend call in shows – perfect. Pitch the “non-marketing” aspects of this; that you won’t be there to toot your horn, but just offer good advice.

Weather-speciﬁc sponsorship. This may not be as critical for the plumbers in the crowd, but it’s an obvious alignment for HVAC companies. Tie this sponsorship up with related giveaways such as an outdoor thermometer.

A pre-built, fully-integrated ted system, A. O. Smith’s commercial tankless racks are offered in wall-mount, in-line or back-to-back free-standing ng configurations. Designed d to reduce installation time and expense while providing a clean, professional ssional look, the racks use the company’s ompany’s CT-199 condensing tankless heaters, which feature a maximum temperature setting of 185°F and Energy Star® qualified 96% thermal efficiency. Up to 20 tankless heaters can be linked with a Multi-Unit Controller.

hotwatercanada.ca BLITZFLEX – THE NEW AIR-INTAKE SOLUTION

Charitable tie-in. As mentioned, radio stations have stepped up their commitment to the community through sponsorships and on-site participation in charitable events. If your company is a title sponsor or leads a charitable initiative, a side-effect may be some proﬁle on the radio.

Save time and money on every job with BlitzFlex, Centrotherm’s new air-intake solution. You need only two SKUs to complete your intake run. Simply uncoil the ﬂexible intake liner, support the run and terminate with Centrotherm’s BlitzKit. Designed to handle offsets, BlitzFlex requires no glues, primers or solvents.
