A few things to keep in mind October 2012 – Plumbing & HVAC

“I can’t take a leak.” “That’s why I only use Dahl valves.” Nothing makes my blood boil like going back on a job to replace a leaky valve that’s caused water damage. I just can’t stand it, and now I don’t have to because I’m using Dahl valves, covered by a 25-year warranty. With Dahl on our trucks, I sleep better at night. Interested?

It’s not easy... It’s not easy running a business these days – and it’s probably not going to get much easier. That’s what Pete Luckett told delegates at the recent HRAI Annual Conference in Halifax. “Canada’s green grocer” has a point. And it’s probably getting even more difficult in this business that it is in selling groceries. People need to eat and that will never change. Food is a “consumable.” People need heating, air conditioning and plumbing too, but modern equipment has become reliable to the point that the “annual tune-up” has largely gone by the wayside for most homeowners. Customers call only when things break, but that’s not too often these days. It used to be that when the weather got either too cold or too hot, the contractor could count on his call volume increasing substantially. With the combination of more reliable equipment and wacky weather – cooler summers warmer winters – that doesn’t seem to happen as much either. As a result, the average contractor today is always searching for new business and new customers. And then there’s customer service – keeping the customer base that you have. It’s always a fine line between ignoring your customers and being in the customer’s face to the point that they start to question your motives. And where this line is can be different from one customer to the next. But being successful in business is a matter of building relationships, one customer at the time, as Pete says. The bigger you get, the more difficult this becomes. You rely on each individual employee to build relationships with the customers they serve. They become diplomats for the business in the larger world. That’s why personality is so

important in hiring the right people. At the same time you have to be careful not to hurt the business. The person who answers the phones, for example, can make or break a small business. As attractive as getting a telephone answering machine and saving the cost of an employee might seem, a lot of prospective customers will just hang up. As Pete says, put a stick of dynamite under it. There are other things that contractors can do to keep afloat that don’t directly relate to increasing sales. Owning your own building, especially if you’ve got some extra space to rent out, can be a real benefit when times get tough, as Ron Coleman outlines in the article in the back of this issue. And I guess that is the key. Always be open to opportunities. Be willing to broaden your service and product offering. There was a time when air conditioning was new and there were contractors that did nothing else. Being specialized to that degree just doesn’t work anymore. To be successful today a contractor always needs to be open to expanding his scope of work into new but related areas of business. It means constant change and improvement. It means individual attention to each customer. And, like so many things, it’s easy to talk about but not so easy to do.

Individual customer attention key to business success, HRAI members hear By Simon Blake here’s no quick and easy way to build a business, HRAI members heard recently. “We can never lose sight of the importance of building a business one customer at a time,” said Pete Luckett, “Canada’s greengrocer” and owner of Pete’s, a small grocery store chain in Nova Scotia. He was speaking to 260 delegates and companions at this year’s 44th Annual Meeting and Conference of the Heating, Refrigeration and Air Conditioning Institute of Canada (HRAI), held in Halifax Aug. 22-25. Understanding your customers and what they need is critical, he added. “Every customer wants to feel the love. The minute you lose that, the business starts to crumble.” One of the problems for business owners today is that customers have a lot of choice and, thanks in large part to the internet, come armed with considerable information. “We are under constant eyeballing from our customers… If a customer isn’t happy, it’s all up on Facebook or Twitter the next day.” But customers are under pressure too. That means bringing a human touch – speaking directly to them – and humour into their lives. One of the worst things a business can do is install an automated telephone answering machine. “If you’ve got one of those things in your business, put a stick of dynamite under it,” he advised.

Need-to-know A new feature at this year’s HRAI conference was the Need-to-Know session where HRAI staffers outlined some of the key issues facing the industry.

HRAI president Warren Heeley noted that a new B.C. stewardship regulation that requires the industry to prove that its products are being recycled and not ending up in landfills “is a trend that may start rolling across other provinces in the next few years.” HRAI has convinced the B.C. government that the industry can manage this through a “business as usual approach,” he added. Because of the high metal content in HVAC appliances, they are typically recycled. The industry already has its Responsible Equipment Management (REM) program in place. However, by the end of next year, B.C. contractors must verify that equipment doesn’t end up in a landfill, so the new regulation will likely at the very least require more paperwork. Technical advisor David Terlizzi noted that one of the biggest challenges for the industry is the deharmonization of codes and standards as each province and municipality tries to be greener than the next, forcing manufacturers to offer different products for each market. “The more we diverge, the more testing is required and the more cost… no one wins,” he said. HRAI is working with standards committees, politicians and CSA to find a solution. Contractors are facing increased competition as utilities try to “grow their business” into the HVAC market, reported Martin Luymes, HRAI director of programs and relations. The trend is growing as both gas and electric utilities find themselves under increased pressure from governments to promote energy efficiency. These were just some of the presentations in an event that was well received by delegates.

Unsavory door knockers

Sometimes a stick of dynamite can be a business solution, says Pete Luckett.

He noted that utilities, tired of policing door-knockers, are re-evaluating allowing access to their bills. The Ontario HVAC Coalition is urging them to stop the practice. Luymes also suggested launching a consumer education program. HRAI is already running a “leave it to the experts” campaign to advise homeowners on the dangers of do-it-yourself HVAC installation and repair.

Every customer wants to feel the love. The minute you lose that, the business starts to crumble.

The HRAI Contractors Division heard how aggressive door-to-door sales people are hurting the industry as they move from selling water heaters into HVAC equipment. It’s one of the biggest consumer complaints today, reported contractor Roger Grochmal, AtlasCare, Oakville, Ont. “There’s a lot of unsavory things that come from doorto-door sales…” he added. Another contractor reported a case where an elderly woman was convinced to change out a three-year-old high efficiency furnace. One of the reasons these people are successful is that they present themselves as a utility company employee, noted Luymes. In Ontario, these companies

Clear advice on venting Dear Editor: I wanted to compliment you on what I thought to be one of the clearest, most thorough, and most direct articles I have ever seen in any of Canada’s publications that serve our industry. I am referring to the article submitted by Steve Bagshaw on venting (The nuts and bolts of tankless vent design, July/Aug, 2012). Although Steve primarily writes from a tankless heater aspect, this article actually deals with all venting applications, be they tankless, storage, furnaces, or whatever. It essentially deals with all applications. My hope that this article is read and understood by as many contractors as possible. Far too many times our industry has dealt with badly or incorrectly installed venting applications. Manufacturer’s instructions for

change Sept. 25. In addition to the new name, the show will now run Wednesday through Friday, rather than Thursday through Saturday as in the past. In the past exhibitors have complained that Saturday was slow, although attendance has varied from year to year. The change was made after organizers surveyed exhibitors and attendees.

The biennial national trade show has been operating since 1972, serving the HVACR and plumbing industries in Canada and internationally. The next CMPX trade show will be held March 19 21, 2014 at the Metro Toronto Convention Centre. The 2014 show is expected to attract more than 14,000 industry members and feature over 450 exhibitors as well as a wide variety of technical seminars. ✚

Letters venting their appliances are very clear and must be adhered to. There are no exceptions. As Steve stated: “If your jobsite’s venting requirements exceed the manufacturer’s limitations, use another appliance; don’t force the issue.” Good job Steve, and Plumbing and HVAC!

Energy economics Editor’s note: The following letter was addressed to P&HVAC author Bruce Nagy: Dear Bruce:

I just read your article (Energy economics changing, September, 2012) and found it to be very interesting and technically well laid out. It should hit a nerve (good one) with contractors in this industry as to how electrical generation will shape the type of equipment we will be using – actually are using – taking into account the technology to conserve what we produce and control the supply of electricity from a number of sources in the near future.

Surprises in oil tank report Old tanks not the biggest problem he majority of domestic heating oil tank failures involve newer tanks, according to a recent report by the Insurance Bureau of Canada (IBC). The Industry Report on Altlantic Domestic Oil Spill Claims showed that of 663 claims between 2008 and 2011, 133 were related to tanks that were zero to five years old and 293 claims were made for tanks from six to 10 years old. However, only 376 claims were directly related to the tank. Other sources of oil escaping were the filter system, fittings, valves or nipples, the burner or the line. Five hundred of the 663 claims involved outdoor tanks. Not surprisingly, over 50 percent of the spills resulted from corrosion. And, of 356 corrosion related claims, 279 involved outdoor tanks. There was little difference in the number of claims related to 14 gauge (322 claims) and 12 gauge (297 claims) steel tanks.

The changing world of

fluid piping New materials offer more options for contractors Fusion welded polypropylene is gradually gaining favour.

he last 30 years have seen astounding kitchen appliances have become the norm. With some changes in piping materials and methods, 50-plus piping connections and hundreds of feet of pipe primarily due to the introduction of new all under constant pressure in a modest (by today’s polymers to the piping industry.

Piping failures of accepted by the industry. Let me state for the record Large-scale distribution that I believe that plastic piping potable water systems are systems were the early systems of good quality adopters of plastic pipe. My every insurance company’s material, correctly installed, will first experiences came with provide many generations of fusion welding of high nightmare these days… trouble-free service. I repeat – pressure polyethylene gas pipe good quality material, correctly – a satisfying experience that installed. led me to accept plastic pipe as not just an equal of metallic pipe, but in many respects, a superior method of Today’s hydronic piping conveying liquids and gasses to their intended point of Hydronic heating systems today are a real mixed bag use. Outside of very high pressure transmission mains, it when it comes to piping materials. What are we finding is hard to find any metallic pipe being put into service out there? It depends on where in the system you look. for natural gas distribution piping these days. Radiant floor heating systems are almost universally Plastic water piping has had a bit of an up and down done with PEX pipe these days. Radiant ceiling and wall experience in building use, but in the controlled environment of municipal water distribution, it has also become the accepted norm, as has branch sewer piping.

T A talented technician can build a masterpiece like this in steel.

Mixed success The introduction of plastics into internal home and building water distribution has had mixed success due to some materials and fittings being unsuitable for their intended use – perhaps as a result of over enthusiastic promotion by manufacturers and sales people – but also sometimes due to lack of training, care or attention to detail by some installers. Piping failures of potable water systems are every insurance company’s nightmare these days, especially when modern houses are absolutely riddled with water piping.

New materials for fittings, like polysulfone, are increasing the longevity of those systems.

Many systems combine several different piping materials.

panels may use PEX pipe, but copper is also common due to higher temperature requirements, especially for ceiling panels. The different flavours of PEX pipe all seem to be performing just fine, with some minor issues only showing up in some of the fitting and manifold components. New fitting materials for joining PEX are seeing the light of day now – glass reinforced noryl, polysulfone and other exotic plastics are proving to be tougher and more reliable than many metallic fittings. We are also seeing a whole new generation of crimp and compression fittings. The big deal with all of these varied systems is to make sure that the pipe manufacturer is okay with the type of fitting used with their pipe. Many pipe manufacturers will only stand behind their product if it is used with the type of fitting they, and only they, approve. It is up to the installer and designer/engineer to ensure that the materials they use are compatible with each other. PVC, CPVC and other solvent-glued materials have never really gained acceptance in hydronics piping. Material velocity erosion and chemical stability under elevated temperatures have made most hydronic technicians leery. Most code officials would probably reject such installations as unsuitable for the potential high temperatures that could develop in a hydronic heating system.

Boiler piping Near boiler piping has been increasingly done in copper, but with copper prices rapidly approaching precious metal status, we are seeing some installers defaulting back to steel pipe and malleable iron fittings. I have seen some very good steel pipe systems – they are not elegant, but you can’t question their track record for reliability. And if you clean the pipe dope and oil off of them and insulate or paint them, they can look quite snappy. Many of those still using copper seem to be

For near boiler piping, soldered copper is probably still the favourite material.

embracing the press-fit method of joining pipe, and some high-end systems are being put in with schedule 20 stainless steel pipe and press-fit fittings. High cost is the biggest enemy of these systems, and fittings and other compatible components usually require some forward thinking in order to have everything on the job when you are ready to go.

It only takes a single breach to turn a home into a mushroom farm during a few hours of uncontrolled discharge. Polypropylene (PP) is new to the North American market and I think it is near perfect for hydronics distribution and boiler room piping. Many sizes – cheaper than copper – an increasing variety of available fittings, valves, and accessories are all helping to make it practical. Installation tools are expensive initially, but consumables like glue and solvent are eliminated; so the long-term economics look good. You can usually rent the fusion tools for the first few jobs in order to see how you like it. Fusion joints are really no more difficult than solvent cement joints, and a darn sight easier than cutting and threading or soldering of traditional pipe and fittings. No MSDS is needed, no open flames, no cutting oil pipe dope and metal chips all over the place. And the material is almost chemically inert. Corrosion isn’t going to happen. Why do you need to fuse it? Well, in addition to the fact that fusion is the “purest” way to join pipe and fittings because it all becomes “one” with the pipe, any solvent

strong enough to dissolve PP would be so toxic that you would need a hazmat team on standby every time you opened the jar. PP is gaining market share in Canada – which means the level of available support is increasing.

The bottom line This is a very broad topic and could take up many more pages, so I will cut to the chase. I think that much of this new technology can help you enhance your bottom line and differentiate your company from others. I believe you should investigate, keep an open mind, and try to see what works for you. It is understandable that many want to stay in the “better the devil you know, than the devil you don’t” mind frame, but standing still doesn’t advance your company. Bottom line? It seems to me that the most important thing to check these days (if you want to try some of this new stuff) is; who is standing behind (providing warranty to) these systems. Do you know the people who are recommending and supplying these systems? Have you done business with them before? Are they going to be there for you 10 years from now if something goes wrong? Have they been reliable in the past? I guess what I am saying is – do you know where they live? You might have to give them a call and you want the number to still be in service, with a live operator standing by. One more thing – review your liability insurance if you really feel adventurous! ✚

PRESSING STAINLESS Press-to-connect systems ease stainless steel pipe and tubing installation By Simon Blake ress-to-connect systems for copper tubing have been available for almost 15 years in Canada now, and much longer in Europe. It was only a matter of time until similar systems would be made available for stainless steel pipe and tubing. Two systems are now widely available in this country. Victaulic introduced its Vic-Press system and Viega offers ProPress for Stainless. These are very different systems. Components are not interchangeable. The Vic-Press system is designed for use with off-the-shelf Schedule 10S stainless steel pipe in sizes from ½-inch to two inches, while Viega’s Pro Press system is made in the same tubing sizes as the company’s copper Pro-Press fittings – from ½-inch through four inch. In fact the company provides not only the fittings, but also the stainless steel pipe. Both systems offer a full range of couplings, fittings and valves for Types 304 and 316 stainless steel. Both use a press tool that the contractor must buy to press the fittings. And while the main joint strength comes from the press connection, both companies also use a rubber seal available in three grades depending on the application:

Vic-Press proved ideal in this industrial application.

Traditional methods • EDPM – for typical plumbing and air line applications, • HNBR (Grade H) – for propane, natural gas, oils, and … • FKM (Viton) – for more aggressive substances and higher temperatures. • It’s critical that the correct seal is used for the application.

Stainless steel pipe or tubing is typically used in applications involving all types of water, aggressive liquids and chemicals, food applications, compressed air, inert gases, dairy barns, etc. And sometimes it’s been used in to replace copper

And as with copper, the major appeal of using a press-toconnect system is labour savings. Quicker joining can be done by workers with a lower skill set. This makes it easier to keep the job on time and helps mitigate skilled labour shortages. “The biggest advantage (of a press fit system) is installation time. It’s a very simple system to learn to use and install,” noted Conn McAdorey, Ontario industrial business development manager for Victaulic. Another big advantage is cleanliness. Unlike with threading, the contractor doesn’t have to flush cutting oil and metal shavings out of the system. And, obviously, there’s no flame as in a

This boiler system was piped with ProPress for Stainless.

Victaulic offers its Vic-Press system in sizes from ½ to two-inches in 304 or 316 stainless steel. “Above two-inch it’s speedier and more economical to install a grooved system,” said McAdorey. “The biggest benefit of our system is that it is used with off-the-shelf Schedule 10 stainless steel pipe. It’s more readily available and it’s what engineers are used to specifying.” (Pipe must conform to ASTM A312.) Other advantages include resistance to bending and flow rates, said McAdorey. Vic-Press works for systems up to 500 psi and with liquids ranging in temperature from -30 to 300ºF (-38C149C), depending on the gasket material. As well, Victaulic offers its own 18-volt press tool. The installer simply cuts the pipe square, deburs it, marks the insertion depth, pushes the connection into place and presses it. The O-ring is pre-lubricated and the fittings are shipped in sealed packages. The system is pressure checked for leaks like any other pipe system.

Longevity Press fittings are relatively new and there remains some skepticism over their longterm reliability. Explaining the history and benefits helps overcome this, said McKinnon. “We’ve had systems (in Europe) that have been around for over 20 years.” Viega warranties its fittings for two years and the life of the system depends largely on the aggressiveness of the liquid flowing through it. If it’s a particularly aggressive This yogurt plant was piped with Viega ProPress chemical, the stainless for Stainless and Viega pipe. system may last only a few years, but it was likely installed emphasize is that although press-tobecause the previous pipe material connect connections are relatively easy and joining technology had an even to make, doing the installation shorter lifespan. correctly and to code requires a skilled A flanged or threaded joint can installer.

The Viega approach Viega took a different approach. It offers its system in standard copper tube sizes. This allows those contractors that are already using Viega’s copper ProPress system to offer stainless steel without buying any additional tools. The same system is used from ½-inch to 4-inch, so multiple tools are not required throughout the size range. The only change is to use a stainless wheel in the tubing cutter. The press tools are available in manual or battery operated versions. Like other Viega press systems, Viega ProPress for Stainless fittings offer the company’s Smart Connect feature, which allows installers to easily identify unpressed connections during pressure testing. Viega ProPress stainless fittings are designed for use with Viega stainless steel pipe. Viega stainless steel pipe is available in 20-foot lengths from ½inch to 4-inch in grade 304 or 316. Viega ProPress for 316 stainless pipe and fittings are NSF certified for potable water.

Viega’s MegaPress system brings press-connect technology to black iron pipe.

Press system for black iron Viega has introduced a new press-fit joining system for black iron pipe. MegaPress and MegaPressG systems are designed for installing Schedule 5 to 40 black iron pipe in sizes 1/2” to 2”. Like the company’s ProPress systems for copper and stainless steel tubing, the system uses modern cold press connections. The MegaPress system is designed for hydronic heat, chilled

water, compressed air, fire sprinkler systems, low pressure steam and vacuum lines. The Viega MegaPressG system is designed for use in fuel oil and natural gas applications. Over 200 fittings are available for both systems including elbows, couplings, reducers, tees,

reducing tees, threaded adapters and unions. The fittings use a stainless steel grip ring with an EPDM sealing element for the Viega MegaPress system, or HNBR for the Viega MegaPressG system, along with a stainless steel separator ring that ensures the sealing element and grip ring perform at maximum capacity. The company’s Smart Connect feature provides a quick and easy way for installers to identify connections that need pressing, so they are not missed. MegaPress systems use the same pressing tools as other Viega press-connect systems. Viega u www.viega.com

■ Heating Mounting the unit above ground allows drainage in the defrost mode.

Heat pump installation Nuts and bolts issues that the technician must keep in mind By Bob Bettles and Brian Guttormson n the previous issue we covered some of the sales and application procedures to be remembered with air-to-air heat pump split systems. There are many other heat pump products including geothermal and mini-splits with single and multi-head circuits. Also coming into the marketplace are high SEER systems with solid state modulating capacity and variable speed compressors. These have quite sophisticated proprietary control circuits, which can out think service technicians and in some cases even the design engineers! These models do require factory training to purchase through selected dealer networks. Heat pumps have made a resurgence in the HVAC marketplace in the past few years, with equipment SEER and EER ratings increased and with government

incentive programs providing a boost. Manufacturers have stepped up sales and development efforts and made their heat pump lines more attractive by helping with end costs and easy service availability. We must remember that in some outlying areas heat pumps sales have never missed a beat and in others only a few are sold annually; these are the areas seeing the sales gains.

Dealing with heat In any HVAC system we’re dealing with heat, whether we are adding or removing it. We cannot add cold, only by removing heat do we create cold! In our typical air conditioning system, by removing latent and sensible heat from the unconditioned air we create a cooler conditioned air for distribution.

A heat pump system has a few extra parts beyond our typical air conditioning system. The key to this operation is the addition of a reversing valve to redirect our refrigerant circuit flow during the heat mode. A second metering device is added at the outdoor condensing unit, also in the liquid line. This is required because, when in the heating mode, we will use the outdoor condensing coil as the evaporator of the system and we will need to monitor the amount of refrigerant that will flow into our coil. This metering may be of the fixed orifice type or an expansion valve. Also our heat pump system must have a multi-stage thermostat that is capable of switching the system from A/C to heat pump operation and also to an emergency heat mode. This will require extra control wires to be run during an installation. Check with the manufacturers’ manuals for further details

The reversing valve, surprise, surprise, reverses the direction of refrigerant flow.

Plumbing & HVAC – October 2012

The main key to a heat pump system is the reversing valve. This assembly is the “tour director,” with four refrigerant connections and a low voltage solenoid to shift refrigerant flow to the system. These valves, in most models, will fail in the heat mode and must be powered by the “O” circuit from the indoor thermostat for cooling or by the defrost control for defrost operation. Older units failed in the cool mode and were powered by the “B” terminal when heating was desired. In the heating mode the superheated refrigerant discharge gas from the compressor is directed to the indoor coil, which now becomes the condenser coil section. This hot gas heat, with the help of the blower motor within the indoor unit, is extracted off of the coil’s fin pack and distributed throughout the conditioned space. Unlike a typical forced air furnace, this heated air will be a much lower temperature than the older fossil fuel appliance many homeowners have been conditioned to expect. However, the longer cycle of the heat pump heating system does provide more even temperatures within the dwelling. During spring and fall, the heat pump system will usually provide all of the heat required for the dwelling.

www.plumbingandhvac.ca

As the outdoor temperature drops, our heat pump capacity is also reduced. Once this thermal balance point is reached additional heat must be added either from the fossil fuelled furnace with the heat pump operation terminated or, if installed as an all-electric system, elements may then be staged on in steps to assist the heat pump to maintain indoor comfort levels. An outdoor temperature sensor must be used with a heat pump multi-stage thermostat. This sensor is wired into the system thermostat that is programmed to the outdoor temperature balance point so that when the heat pump is no longer efficient to run (heating or costs) and the heat loss is not met, the electric heating section is energized with the heat pump section or turns off the heat pump and the fossil fuel satisfies the heating set point. In a fossil fuel “add-on” system the indoor coil must be installed downstream from the heat exchanger. When the balance point temperature is reached, the heat pump must be shut down as allowing heated air to enter the coil will cause issues with the refrigerant system. In an all-electric system the coil is installed upstream of the elements. The elements see tempered warmer air from the coil and boost the temperature of the conditioned air for the space.

Operating in reverse While the system is operating in reverse to extract the heat from the outdoor air to heat the space we are also cooling at the outdoor section which now is the evaporator. A by-product is frosting of the exterior coil.

www.plumbingandhvac.ca

The build-up will affect system operation and a defrost cycle will be initiated. A defrost cycle is accomplished by shifting the reversing valve to cooling mode and directing the hot gas to the outdoor coil. While defrost is occurring, some defrost controls will provide a heat-during-defrost option (HDD) to allow the indoor section to bring on electric elements to temper the air delivered to the conditioned space. In most cases with an add-on system, the HDD option can be ignored as usually the defrost timing prior to the balance point changeover will not be excessive. The outdoor section of the heat pump system must be installed on a secure base and elevated with a fabricated stand above the local snow level. The water generated during defrost must be able to drain clear of the unit’s base pan. If this water is allowed to accumulate around the coils, non-warrantable ice damages will occur. Avoid using the angle iron wall brackets so popular in the new home market as objectionable sound levels can and will be generated in the dwelling.

Surplus refrigerant Most models today include an accumulator. This serves several purposes. As indoor and outdoor coils do not have equal internal capacity, additional refrigerant that is not required may remain in the accumulator depending on the mode of operation. It also prevents liquid shock in the compressor when the reversing valve is shifted. If a compressor fails the accumulator should also be replaced. These are close-coupled at the compressor’s suction line connection and any debris or

acid from compressor failure will end up in the accumulator. No amount of vacuuming the system will remove these contaminants. Depending on how the compressor failed, the reversing valve assembly may have to be changed as well due to contamination or debris. Also, never sweat out a reversing valve assembly. It’s always best to cut it out and re-pipe the new one in. Debris in this assembly may, when heated, migrate beyond the assembly causing an additional failure on restart. As well, use reputable heat sink products and nitrogen to protect the new valve. ✚

Maintaining even heat

Or how careful design will keep your customers’ feet toasty By Mark P. Evans ome people don’t welcome the recent change in seasons and dread the thought of enduring another Canadian winter. A common complaint is that they just can’t seem to warm up due to poor circulation. As a heating technician, I see the

For new installations, I remember to keep the loops the same length in each zone then connect them to supply and return manifolds that incorporate balancing valves so it’s easy to maintain even heat throughout the target area. A properly sized boiler will produce enough hot water to satisfy the heating requirements based on the heat loss calculations, but it’s up to the heart of the system, the re-circulating pump, to put that water where it’s needed. The re-circulating pump makes use of centrifugal force to create a pressure differential that will cause the water to flow as long as all the air has been purged from the system. Most problems with a hydronic system can be attributed to this cause. Air separators and air vents, installed at all the highest points, will permit the pump to do its job and result

Continued from page 25 in a quieter operation. In fact, the only sound heard should be the gentle hum of the pump motor; anything else indicates a condition which will reduce effectiveness. Installing a re-circulating pump creates a closed system and therefore several other components must be incorporated to handle the resulting conditions. A check valve downstream of the pump will ensure direction of flow and an expansion tank will manage the fluctuations in water density as it is heated and cooled.

scrutinized is the piping system itself. The layout of many heating systems, which I get contracted to expand upon, seems planned only as far ahead as the fitting the installer had in his hand at the time. Wild configurations give the impression of randomness and appear pointlessly complicated. Piping diagrams are provided from the manufacturer/supplier for in-floor systems; a few minutes spent creating a similar drawing for the domestic piping would be time well spent.

■ Refrigeration

Quebec grocer adopts Chain plans to convert 1,300 stores By Bruce Nagy

CO2 W

e tried synthetic refrigeration gasses for about 100 years. Now we’re looking back at refrigeration as it originally worked, and contemplating the return to CO2 as a refrigerant. This is especially true for grocery stores. After comparative technical studies, a few years of practical test applications in stores, international discussions on goals and standards, research and development solutions to some of the early problems, everything adds up to the much greater use of CO2 worldwide as an integral part of supermarket cooling and heating systems.

Many different areas in the store require cooling.

Among the main developments are that heat is being reclaimed from refrigeration for use in supermarket space heating and hot water. At the same time, refrigerants that support these functions must become less expensive, less frequently recharged and less harmful. This increasingly means mechanical systems that use CO2. As usual the transition is not easy. Investors have to bet on something different, engineers and governments must mitigate risk, manufacturers must remain openminded and nimble, installers must be receptive and fully trained.

Mirabel IGA

The Mirabel store features a state-ofthe-art CO2 refrigeration plant.

Plumbing & HVAC – October 2012

In one Quebec application the installer, manufacturer and engineers all work for the same two sister companies: LMP and Lesage. Inside the factory they built a lab – basically a small supermarket. “We wanted to test our inventions to make sure they do what we say,” said Xavier Marle, Lesage director of operations. Their current most advanced demonstration project is an IGA store in the Mirabel area. The store uses CO2 (R744) for refrigeration and a secondary glycol loop for heating the space and water. “Service calls in two years have been minimal. I can count them on two hands and most of them relate to motors. It’s because we took the time to get the engineering right from the beginning. The system works beautifully,” reported Marle. The Mirabel store is part of the Sobeys group. Sobeys expects to have 30 new stores using transcritical refrigeration by the end of 2012. It is also retrofitting six existing stores and, within about 15 years, all 1300 stores will employ this or similar technology. The company also has nine stores with cascade systems, which combine CO2 with traditional synthetic refrigerants, but www.plumbingandhvac.ca

it has now eliminated this that its CO2 system achieves configuration from the plan and almost the same efficiency as an moved ahead. R507 system. Sobeys reports that CO2 Freezers and medium refrigeration is proving about temperature refrigerators could 18 percent more energy efficient be cooled directly using CO2 than its conventional systems, lines.

So it’s easy to calculate the impact of energy savings. If they save 25 percent on Sobeys reports that C02 refrigeration is energy, they increase their profits by the same amount. proving about 18 percent more energy efficient Refrigerant cost is becoming an issue.

Countries are now beginning to talk about or actually legislating prices for carbon emissions and taxing refrigerants. In Australia and other places synthetic refrigerants cost 10 to 20 times as much as CO2. This might be the extreme case, but the trend is global.

Holistic energy approaches Heat reclamation, floating head pressure, pipe insulation and CO2 as a refrigerant can and must be complemented by an expanding portfolio of new energy conservation measures for grocery stores. Lighting is often a huge expense area and LED lighting, along with dual level switching and occupancy sensors, can affect both electricity loads and instore temperatures. It’s easy to implement a host of other simple improvements like ECM motors, automatic door closers, night covers, glass doors, strip curtains and door gaskets for walk-in boxes. Some of these are great new inventions. CO2 for refrigeration is a wonderful old invention, especially when combined with modern mechanical engineering. ✚

A plumbing solution Need to reduce landfill and composting costs shifts focus to food waste disposers By Andre Dupuis

Research shows that food waste disposers have little impact on sewage treatment plants. As a result, municipalities like New York City have lifted long-standing bans.

www.plumbingandhvac.ca

oday, almost everything is more complicated, but that’s not always a bad thing. Under pressure from environmentalists, green building certification programs like LEED appeared, requiring a more integrated global view of the technologies used in a building. Thus, not only must the equipment be efficient, but its manufacturing should create as little impact as possible on the environment, including the ability to recycle the product when it has reached the end of its lifespan. This global vision, upstream and downstream of the useful life of a the actual plumbing or HVAC equipment, led to the concept of “ecological footprint” and “life cycle analysis,” among other things. And in some case it required a fresh look at processes or equipment that had been challenged in the past. Such is the case with food waste disposers that typically grind up organic food waste and flush it down the drain. At a time when many municipalities want to minimize the amount of garbage going to landfills, they are getting a second look. Let’s see how a global vision can provide a different perspective on food waste disposal based on a multi-year experience in Surahammar, a small town of 10,000 residents in Sweden.

Reducing greenhouse gas emissions

is known to potentially be up to 25 times more damaging than carbon dioxide (CO2) for global warming. In 1999 the maximum allowable amount of biodegradable materials sent to landfills was reduced. Based on 1995 levels, the reduction was 25 percent in 2006, 50 percent in 2009 and another 35 percent in 2016. To achieve this goal of reducing the volume of biodegradable materials for the trash, the city of Surahammar offered three options to its citizens. The most expensive was to collect compost once a week (twice a week in summer). The most economical (no charge) way was to recycle these materials at home, in an approved composter. Finally, a third option was to rent a food waste disposer from a municipal agency for a period of eight years. If a video drain inspection revealed that the drains were in acceptable condition, the owner was eligible for the installation of a food waste disposer by the municipality, which assumed the costs of installation and maintenance. After eight years, the food waste disposer belongs to the homeowner with no additional fees for garbage collecting. The annual rental cost of the disposer worked out to the equivalent of $40 Canadian, while the collection of biodegradable materials added $320 to the tax bill. Not surprisingly, this cost differential made the disposer option extremely popular. Out of 3,700 homes, 1,100

It all started with a European Union decision to reduce emissions of methane (CH4) from landfills since this gas

Freezeless AND Anti-Rupture? What’s the difference? A freezeless faucet has the shut off mechanism well within the heated portion of the home – but what if a garden hose or other device is inadvertently left connected to a faucet during freezing temperatures? Water in the tube fails to drain, this water then begins to freeze and pressure in the tube is increased as ice forms and tries to compress the water trapped in the tube. The tube ruptures and the next time the faucet is used the wall fill with water. Woodford Model 19 Freezeless Faucets have a patented pressure relief valve which allows for expansion during freezing temperatures, saving the faucet and preventing a costly repair or call back. With Woodford’s Model 19, you’re protected – even from other people’s mistakes!

Food waste disposers Cont’d from page 33 food waste disposers were fitted in the first year beginning in 1997. By June, 2008 the proportion of homes with food waste disposers had reached 50 percent.

Sewage system load results The city’s 3,700 properties are connected to a sewage system that directs all material to a single wastewater plant, which has greatly facilitated the collection of data. In January 1995, a statistical analysis was performed before the installation of the food waste disposers to provide a base figure. After the disposers were installed, the study could not demonstrate any significant increase in water consumption. Volumes of waste water were maintained within normal seasonal amounts. The increase in water consumption was negligible. The authors of a study of the Surahammar project noted that New York City also studied the impact of food waste disposers in 1999. The largest study of its kind ever conducted, it found that at 2.4 uses per day, 16 to 38 seconds each time, they arrived at approximately 3.1 litres of water use per day. After banning food waste disposers for 18 years, New York City stated that its position was not based on scientific facts and lifted the ban. Electricity consumption proved low too. With a 0.5 to 0.75 hp electric motor, operating 2.4 times per day, the annual electricity consumption amounted to about 3 KW/h per household. Interestingly, it was also found that water and electricity consumption was less related to the number of people in the home than to the type of meal prepared.

The team responsible for sewer maintenance reported no change in corrosion, broken pipes or additional accumulation of sediment, oil or grease as a result of the use of food waste disposers. The main fear was that the organic matter might attract rats, but it seems that food waste shredded into fine particles is not a popular dish for these rodents, which apparently prefer to get something more chewable to eat. The contractor responsible for pest control measures found that there had been some problems with rats resulting from bad composting facilities, but nothing related to the installation of the disposers. At the wastewater plant, after a short increase following the installation of the disposers, the total load (biological oxygen demand, suspended matters and total nitrogen) pretty much returned to the previous values. Phosphorus was reduced slightly, which could also coincide with the reduction of phosphates in detergents.

Dollar savings

These anaerobic digesters at St-Hyacinthe, Que. play a key role in the city’s waste reduction strategy.

Anaerobic digesting plants Anaerobic digesters use microorganisms to break down biodegradable material (or compost). The process creates methane gas, which can then be used as a renewable fuel. Montreal plans to build six anaerobic digestion plants. Longueuil, Laval, Quebec and Riviere-du-Loup also have similar plans. Currently, facilities operate in St-Hyacinthe and Gatineau. Many others are operating in other provinces. Elected officials and municipal managers today have a more complex task than before when it comes to deciding on the management of biodegradable

materials. For each proposed process (wastewater treatment, landfills, incineration and composting), they must ask themselves, in addition to energy consumption, what is the potential in: • Global warming, • Eutrophication (degradation of aquatic environments due to excessive intake of nutrients), • Acidification of the water (increase in acidity of the water and soil), • Contribution to smog. Another question can and should be added: “What role can food waste disposers play in this chain? “ What is the more environmentally and financially friendly, the disposer and the sewer or the garbage truck? ✚

Andre Dupuis is editor-in-chief of Inter-Mechanique du Batiment, the official publication of the Corporation of Master Pipe Mechanics of Quebec (CMMTQ). He can be reached at cmmtq@cmmtq.org.

It has been shown that although 50 percent of the households in Surahammar had a food waste disposer as a means of eliminating table waste, the sewage treatment system did not require upgrading nor did it incur additional costs. Yet, two huge differences could be measured: 1) The volume of waste sent to landfill in the municipality decreased from 3,600 tons per year in 1996 to 1,400 tons in 2007 and; 2) The plant’s anaerobic digester can now collect 46 percent more biogas than before the installation of the disposers.

Heating fuel from waste Anaerobic digestion is a method of using micro-organisms to break down organic materials in the absence of oxygen (anaerobic). This phenomenon is accompanied by the production of a biogas composed of methane (50-75 percent), carbon dioxide (25-45 percent) and some other elements such as hydrogen sulfide (H2S), hydrogen (H2 ), water (H2O), oxygen (O2), ammonia (NH3) and nitrogen (N2). Materials that can be processed by anaerobic digestion include manure, slurry, organic food wastes and sewage sludge. The use of methane from biogas as a fuel meets a number of economic, environmental and energy concerns. Indeed, the biogas can be considered a renewable green energy compared to fossil fuels. The calorific value of 1 Nm ³ of biogas containing 60 percent methane is about 22 MJ and is similar to 0.56 litres of fuel oil and 0.21 cubic meters of propane.

This is just a small part of the MITS hydronic showroom.

Contractors will learn the nuts and bolts of hydronics in the new training centre.

A new face in hydronics By Roy Collver Whatever industry we are part of these days, and whatever role we play in it, one universal concern seems to be the changes taking place in distribution. Traditional distributors of hydronic heating equipment are changing rapidly. Consolidation and buyouts among them have created an increasingly smaller pool to swim in for certain market areas, while nontraditional channels are springing up to try and grab a share of the market. Internet sellers, direct sales by manufacturers to consumers, manufacturer direct dealer network sales – all are muddying the waters. Large consolidated wholesale distributors are narrowing their product offerings to the customer; while bullying suppliers into exclusive, lower margin pricing structures in order to enhance their bottom line – something they learned from big box retail players. I don’t think the trades purchasers are going to be satisfied with: “If something is wrong with this product – DO NOT RETURN IT TO YOUR SUPPLIER – Contact the manufacturer directly at 1-888- YOUR CALL IS IMPORTANT TO US, or www.goodluck.com.” (I saw a similar note with a coffee maker I just bought.) This brings me to an event I attended recently in Mississauga – the grand opening of the new MITS Air warehouse and training centre. Not traditionally a hydronics powerhouse – MITS seems to be re-shuffling the deck in the greater Toronto area hydronics distribution world. MITS president Jack Eliav has made a serious investment in the hydronics showroom/training facility and intends to keep it busy, busy, busy. How much of an investment, Mr. Eliav is unable (or unwilling) to say. His words to me were: “I told everybody to do whatever was needed. You can’t put a budget on something like this.” I was really impressed with what I saw, and outside of the Northern Alberta Institute of Technology (NAIT) in Edmonton, I can’t recall seeing a better hydronics

I told everybody to do whatever was needed. You can’t put a budget on something like this” training centre. Bonus – it is full of “airside” stuff as well. I have always believed that talented HVAC contractors have a great future in the hydronics industry due to their advanced knowledge of controls and integrating heating with cooling – especially important in an air

conditioning dependant market like Southern Ontario. Along with the flash and thunder of the new facility, MITS has committed to stocking parts for everything they sell for at least the expected lifetime of the products – along with a commitment to full technical support. I have heard numerous complaints over the last five years that the traditional hydronics players are abdicating these important functions and it seems as if this new hydronics player has been listening. If they can successfully execute their plans, they are sure to come out a winner. The gauntlet is on the ground. The new MITS facility is located at 1608 Bonhill Road in Mississauga, Ont.

■ Shop Management When it’s time to retire, owning a building can give the contractor a significant boost.

To own or lease How your building could end up being your pension plan By Ron Coleman

mortgage at a very competitive interest rate and the payments should not be onerous. Overall the outgoings should not be higher than your current ones. However, most small business owners cannot manage such a large deposit. The other option is to go the Business Development Bank of Canada (www.bdc.ca). They will often do high percentage financing on commercial buildings. Their rates will likely be higher than the commercial banks, but if you can only manage a small deposit they are your best bet. The other key question is space and location. If the size of the space you are buying and the location are likely to meet your needs for at least 10 years, then buying should be considered. If it won’t, then buying may well be the wrong decision. If expansion is on the horizon and you could afford to buy two bays in a commercial building and rent one out, then that would protect you for the long-term. All the other choices can be made after you make these initial decisions.

any Canadians worry about their financial welfare in retirement. This is of particular concern to many small and medium sized contractors who don’t have much in the way of a pension plan. There is one solution that is often overlooked and doesn’t require you to make ongoing savings and that is to own your own building. That way the money that would have gone to rent is going to pay down the mortgage with the intent of owning a building debt free on retirement.

When you own the building many of these items are not a concern. You are more willing to spend on the improvements knowing that they are yours.

Crunching the numbers The number crunching exercises need to be done to determine if a purchase is better than a lease. This means identifying and comparing the various elements of cost between what the landlord pays and what you would have to pay if you were your own landlord.

should own the building. Talk to your accountant about this and the pros and cons of the holding company owning the shares of your operating company. Maybe you would put some of your equipment in the holding company also. However, be careful of the tax consequences. If the holding company is receiving rent from the operating company to pay down the mortgage there may be some nasty tax consequences as the net rental income received by the holding company will not qualify for the small business rate of income tax – talk to your accountant.

Continued from page 45 become your responsibility; these include the condition of the roof and other exterior costs. Picture the neighborhood in 10 to 15 years time. Do you see it as being more or less desirable in the future? If you are in an area that is growing, then you have a lot more security for the future of your investment. You should never buy your building in your operating company. You should set up a holding company and it

Financing your retirement The average HVAC contractor in Canada did about $2.6 million in sales in 2011 and paid about $30,000 in rent. As the building owner that $30,000 could be coming to you in retirement. Remember you would also have responsibilities for maintaining the building. That’s $30,000 in today’s terms, so it would increase with inflation.

Plumbing & HVAC – October 2012

Alternately when you retire, if prices are right and you don’t want to be a landlord, you could sell the building and generate a capital gain, of which only 50 percent is taxable. This would leave you with a nice lump sum to invest in your retirement. Because many small contractors don’t save much money during their business life and don’t manage to sell their businesses for a lot, this strategy can make a world of difference when it comes to quality of your retirement lifestyle. Investing in your own building and paying off the mortgage so that it is free and clear on retirement is a guaranteed way of ending up with a pension fund. Act now. ✚
