TRENDS

Equipped with larger 9/16" Flexicore wire rope center cable.

A muscular mid-size machine with more power, the Sewerooter T-4 quickly punches through tough clogs in 3" and 4" lines. A larger 9/16" Flexicore® cable does a better job of transferring the torque than traditional 1/2" cables do.

It gets down the line easier and clears clogs faster. And the portable workhorse is easier to handle in tight spaces, on stairs, and loading into your truck.

EDITORIAL

Legislation may be the solution to competition issues

Readers may recall Mechanical Business reporting on an Ontario utility company that has entered the mechanical supply and service markets in July 2022 (mechanicalbusiness.com) and in the July/August 2022 print edition. The story about Hydro One noted that the utility was endorsing three exclusive partners for the sale of an array of residential HVAC and plumbing systems in its franchise area.

Subsequently the matter was brought to the attention of the HVAC Coalition of Ontario by MB. As a precautionary measure, the HVAC Coalition filed for “late intervenor” status in Hydro One’s rate application hearing, which was underway before the Ontario Energy Board (OEB). The OEB denied that request. In its original coverage MB asked “what will other Canadian electrical utilities do when they look at Hydro One’s strategy?” Ontario is not alone as Alberta and other provinces were flagged at the Heating, Refrigeration and Air Conditioning Institute of Canada (HRAI) contractor town hall webinar on September 8, 2022.

Members asked whether HRAI should be creating a plan of action for inappropriate utility intrusions in the Alberta marketplace, and whether the organization should pursue a legislative solution to municipally-owned utility companies engaging in activities outside the scope of regulations under the utility regulator.

Martin Luymes, vice president, government and stakeholder relations for HRAI noted, “It’s a long process, very costly, a lot of hours, and therefore a lot of legal expense, to have success. We’ve had some success in BC and Nova Scotia, but what we’ve found in Ontario is there’s still a need to have an early warning system, if you want to call it that, or a watchdog function in place to keep an eye on utilities.” He added HRAI is working through a process where the HVAC Coalition in Ontario can be folded into the national organization so it will be in a position to act on utility issues across the country.

HRAI is considering its options in the case of municipally-owned utilities. “It’s been discussed that maybe we should tackle this in a different way, rather than always running to the Ontario Energy Board, filing a complaint, registering for a hearing, which is a very complex and time-consuming process. Why don’t we go to the Government of Ontario and request they legislate in some fashion that municipallyowned, electric utilities should be prohibited from entering into businesses where a competitive industry already exists. We believe that the Ontario government is sympathetic to that type of concept,” said Luymes.

Chelsea Goberdhan, HRAI’s government and stakeholder relations specialist –Ontario, noted that HRAI is already reaching out to the province on the issue. “We have been engaged with several ministers and MPPs, trying to establish who can be our champion for this issue, and come up with a regulated solution to solve this problem once and for all. We’ve described this problem as kind of being a whack a mole, where we resolve it in one municipality, it pops up in another. So, formalizing a solution in a regulated way is something that we are developing a plan for.”

Mechanical Business will continue to follow this issue and we encourage stakeholders to make their concerns known regarding utility intrusions in the marketplace.

Feds launch homeowners loan for energy efficiency upgrades

The federal government has launched the Canada Greener Homes Loan Homeowners Stream to offer $4.4 billion in interest-free loans to Canadians retrofitting their homes. Homeowners are eligible for a loan of up to $40,000 per household. The loan, through the Canada Mortgage and Housing Corporation, is part of the Canada Greener Homes Initiative, and builds on the grant offered by Natural Resources Canada. The first phase of the loan has already launched, and is open to eligible homeowners applying or who have an open application for the Canada Greener Homes Grant. The second phase, opening eligibility to homeowners who have closed their applications but still have retrofits to do, is now open.

Vancouver extends energy retrofit program to multifamily buildings

The city of Vancouver, BC has extended a program for energy retrofits and released a guide to the use of heat pumps for cooling and heating. The Bring It Home 4 Climate program, which provides support and resources for residents to identify necessary energy upgrades and solutions, has been extended to owners and renters of multi-family buildings including apartments, condos and cooperative housing. The guide, Heat Pump Retrofit Guide for Strata and Co-op Buildings, offers information on heat pumps and their benefits, and advice for planning a lowrise multi-unit residential building heat pump retrofit project. According to the city, nearly 60 per cent of carbon pollution in Vancouver comes from fossil fuels to heat and cool buildings.

PPI and IGSHPA sign MOU to strengthen geothermal industry

The Plastics Pipe Institute, Inc. (PPI) and the International Ground Source Heat Pump Association (IGSHPA) have announced a memorandum of understanding (MOU) to advance the benefits each organization brings to the geothermal exchange industry. The MOU includes an agreement to advance technical cooperation and development between the two organizations, including opportunities to participate in proposed standards, guides and policies on technical subjects.

Alberta introduces prompt payment measures

The province of Alberta has introduced a bill to ensure that contractors and subcontractors in the construction industry are paid for projects on time. Bill 37: The Builders’ Lien (Prompt Payment) Amendment Act, 2020, features timelines and rules for payments and liens in all construction industry sectors. There were previously no rules for payment timelines. The new bill sets a 28-day timeline for project owners to pay general contractors, and a seven-day timeline after payment is received for contractors to pay subcontractors. Timelines for registering liens has increased in the construction industry from 45 to 60 days, and in the concrete industry from 45 to 90 days. The minimum amount owed that can be subject to a lien also increases from $300 to $700. Other changes include new rules for hold-back money on large, multi-year projects, and improving subcontractors’ access to payment information.

Gas-fired boilers recalled due to carbon monoxide poisoning hazard

Health Canada has issued a recall for LAARS Mini-Therm JX Gas-Fired Boilers due to the potential of carbon monoxide poisoning. The recall includes the LAARS Mini-Therm JX gas-fired residential atmospheric boilers, models JX050 and JX075, serial numbers V21306297 to V22311517. The units are grey and include a front display panel with LAARS MINI-THERM JX on a black and orange name plate or label. The affected units pose a carbon monoxide poisoning hazard because the original mounting position of the blocked vent switch may not allow the boilers to switch off in a timely manner during a blocked vent condition. As of press time there have been no reports of blocked vent switch failures or injuries. Contact LAARS Heating Systems Company for a free repair kit. laars.com

UPDATED RESOURCE IS A VALUABLE TOOL

Manual offers the latest information on ducted forced air distribution systems

The new sixth edition of the Residential Air System Design Manual (RASD) from the Heating Refrigeration and Air Conditioning Institute (HRAI) is the culmination of a collaborative task group, which included nation-wide input from HVAC contractors, HVAC designers, manufacturers of both equipment and duct systems, building officials, energy advisors, utilities, researchers, government representatives and HRAI instructors. The edition is a consensus documentation of the latest information with respect to ducted forced air distribution systems in residential applications. I am reporting on some of the changes and additions I feel will be of help to the residential HVAC industry.

The task group members who contributed to the sixth edition of the Residential Air System Design Manual have recognized and responded to the compelling changes in ever more efficient but complex new houses and the challenges that may present to effective air distribution. Special recognition is due to Tom Cates, a long-time HRAI trainer, who took on the task of doing the technical writing.

Scope reflects important advancements

RASD was reorganized, starting with a concise Section One defining the scope of the document and clearly laying out the minimum requirements of residential forced air systems compiled from the National Building Code of Canada, provincial building codes, and standards that are referenced in those codes. This Section will be helpful to HVAC system

Gord Cooke

designers and HVAC contractors working specifically in the new construction market as it ensures quick access to code requirements for consistency and clarity in preparing building permit applications. Indeed, this section identifies that while the manual may be helpful to contractors in renovation projects, its primary focus is on systems designed for new home construction.

In this regard, the manual has updated the scope to reflect important advancements in equipment, ducting systems, and house construction. For example, the scope identifies a “Total Available Duct Pressure” range of 0.100” w.c. to 0.800” w.c. (25 Pa to 199 Pa). Identifying this specific, and I would say expanded range, recognizes the capabilities of electronically commutated fan motors, and equivalent technologies, to operate at higher system static pressures. The lower range similarly acknowledges the capabilities of smaller capacity, “mini-split” systems that may offer some limited ducting options.

The expanded system pressure range offers important flexibility in ever more efficient houses with much smaller overall heating and cooling loads, but which still have the need to distribute air effectively. The extra system pressure available at the “end of the line” can allow for diffusers with better throw and spread characteristics to ensure comfortable living spaces.

Gord is a professional engineer who has spent 35 years helping builders and HVAC contractors implement innovative technologies into high-performance homes. He has particular expertise in IAQ and airflow management in houses, and can be contacted at gordc@buildingknowledge.ca.

Resolve disputes

Section Two of the Sixth Edition is titled “Optimizing Performance Through Design” and the introductory remarks clearly indicate this section provides good engineering practice information from industry resources such as the ASHRAE Handbooks and the ACCA Manuals. The remarks go on to say that the information in Section Two goes beyond the minimum requirements of Canadian building codes. RASD helps separate or delineate the code obligations of builders and their HVAC trade partners from approaches offered as enhancement or upgrades for optimized performance. I trust that professional contractors will use this important delineation when asked for opinions, specifically in new homes, to help resolve disputes between homeowners and their builders rather than escalate them.

There are two specific topics in Section Two that can be helpful in both new and existing homes. There is good discussion of return air design systems that starts with the concept of return air “pathways.” Recognizing that if conditioned air (warm or cool) is to be effectively distributed to a room or space, there must be an adequate path for air to be returned to the central air handling device. The revised manual provides a wider range of options for contractors to provide return air pathways. Certainly, fully ducted returns offer the most direct path while avoiding potential air quality concerns when using wall or floor cavities. The manual, though, offers more alternatives for central than just the commonly used door undercut technique. Transfer grilles in doors or walls or “jump ducts” between rooms and central hallways have been used successfully throughout the U.S. for two decades. In new construction they can be more cost effective than fully ducted returns and more acceptable from a noise mitigation perspective than large door undercuts. These options can be very useful in existing homes in cases where the effective distribution of supply air is affected by the back pressure in a room with a closed door and an inadequate return pathway.

Rather than opening up walls or ceilings to try and directly connect return ducts, installation of noise attenuated transfer grilles is a very effective option.

The expanded discussion of duct leakage in the Sixth Edition is also helpful in new and existing projects. There is a note to designers regarding how new or recently installed duct systems in some jurisdictions such as Ontario are required to be sealed to the SMACNA Class 3 level –transverse joints sealed. The manual ascribes a duct leakage range of up to 15 per cent in these systems and suggests designers account for this loss in at least long duct runs. These notes provide a good hint in jurisdictions that don’t require duct sealing or in older homes that duct leakage rates much higher than 15 per cent may be affecting proper distribution of air. Expanded information on duct sealing methods and techniques, including the aerosolized sealant method applied under pressure, is provided. Specifically in new low load homes with lower airflow requirements, the need for precision in distributing those smaller flows implies the need for much better duct sealing. In over 25 U.S. states duct leakage testing down to rates in the three per cent to six per cent range are now a code requirement. The objective of lower duct leakage is also highlighted in an expanded section about the use of flexible ducts. References from the Air Diffusion Council design guide for the effective use of flexible duct have been added to take advantage of the inherent air tightness of these ducts while avoiding the challenge of increased resistance due to improper

Basements as livable spaces

A much-needed enhancement of effectively conditioning finished or habitable basements is a welcome discussion in the manual. Fortunately, advancing codes and energy programs are addressing the heat loss through basement walls, floor slabs and air infiltration. Thus, HVAC designers and contractors have more options in ensuring warm, dry, healthy lower living areas. In previous editions limited options for dropping supply ducts and return air runs near the floor or adding supplemental heat sources were provided. The supplemental heat option was often problematic because electric heaters, although very cost effective, prompted code requirements for higher insulation levels.

The new edition provides a better discussion on the challenges in keeping these spaces warm and offers more specifics on conditioning alternatives. For example, there is recognition that the higher total system static pressures, noted above, provide designers with alternatives. Those include using the higher allowable duct pressures to select diffusers with the specific ability to “throw” air across larger spaces and create supply air distribution patterns that effectively bathe exterior walls and slabs on-ground with proper amounts of warm air.

The move towards mass timber buildings − Part II

HVAC and plumbing challenges and the state of mass timber in Canada

Mechanical systems can have a profound effect on the aesthetic appeal of the interior of the structure with its large open spaces, high ceilings and attractive wooden beams.

This is the second in a two-part series about how builders are starting to embrace mass timber construction as a desirable option for residential and commercial buildings. In this second part, we look at the challenges designers and contractors encounter when installing HVAC and plumbing systems in mass timber structures, as well as a review of the state of the mass timber industry in Canada.

The move towards mass timber buildings is underway and gaining momentum each year. Contractors need to stay abreast of this new construction sector and how it will change the way mechanical systems are designed and installed. For more information, go to the International Association for Mass Timber Construction (iamtc.org) and the Mass Timber Institute (academic.daniels. utoronto.ca/masstimberinstitute/).

WHERE TO PUT THE MECHANICAL SYSTEMS?

Experts point to the HVAC and plumbing system design as one of the most important construction processes builders and mechanical trades have to address for mass timber structures. These systems can have a profound effect on the aesthetic appeal of the interior of the structure with its large open spaces, high ceilings and attractive wooden beams.

From the outset, the designer has to determine how the installation of these systems will mesh with the architectural look of the interior of the building. These design decisions will have a

significant effect on the way mechanical systems are installed. In essence, the decisions will determine what components of the systems will be visible versus hidden to create the interior look desired by the architect and builder.

If the architectural design for the structure uses the mechanical systems as a part of the interior look, ductwork, piping and other mechanical components can simply be left uncovered and blend into the architecture. If hiding some or all of the system components is determined, a number of options are available to the designer for the trades to use.

Two such options are building “light frame walls or soffits” and “furring out” mass timber walls. The light-frame wall option can be located on one or both sides of the mass timber wall panels to house HVAC and plumbing system components. The “furred out” option involves expanding a portion of the lower half of the mass timber wall (similar to wainscoting) to house mechanical system components.

Where the design calls for retention of as much of the “wood look” as possible, other solutions need to be used to hide the systems for aesthetics and retain good system performance.

One such option used in mass timber buildings is an “underfloor air distribution system” (UFAD). This system manages the balance between efficiency and aesthetics without requiring the extensive ductwork systems used in traditional HVAC systems. The “underfloor” aspect of the system is actually a raised access floor installed above the air distribution system. UFADs can also be used to run piping and other mechanical components.

One option used in mass timber buildings is an underfloor air distribution system.

Logistically, the raised access floor is built after the mass timber construction is complete and in a configuration that will house the complete HVAC system including ducts and diffusers. The result is a system that is completely hidden and maintains the majority of the building’s aesthetic value. Another benefit of the UFAD system is the mass timber construction process for the building is completed before the mechanical system’s work is started, which makes the whole construction process move quickly and more efficiently.

UFAD systems provide a wide range of improved performance aspects compared to traditional systems, including less time for installation, reduced loss of useable space, less energy use through more efficient air circulation and better ventilation.

The bottom line is design and installation of HVAC and plumbing systems in mass timber buildings take careful preparation and participation by contractors in the design process to ensure trade concerns are taken into account as the design unfolds. There are many options to meet the design expectations and contractors need to have their say on what is needed to “get the job done properly.” And don’t forget, local energy and building codes need to be reviewed to ensure the options used meet local and provincial requirements.

MASS TIMBER IN CANADA

In 2021, Natural Resources Canada (NRCan) in partnership with the Green Construction through Wood program released The State of Mass Timber in Canada 2021, an inaugural report on mass timber construction.

Seamus O’Regan, minister of Natural Resources at the time the report was released, stated “Canada is a world leader in building with wood, and we’re building bigger and taller buildings. Mass timber buildings are highly resistant to earthquakes, offer natural thermal insulation, are inherently fire-resistant, and can be rapidly installed. They’re also a critical nature-based solution to climate change, and an important part of getting to net-zero.”

The report covers the progress of manufacturing and building with mass timber. There is an increasing demand in Canada for sustainable building materials and “sophisticated design and production systems.” The report indicates that mass timber will play a key role “in low carbon construction and developing the bio-economy.”

Canada has completed or has under construction 702 mass timber projects with institutional (283), commercial (173) and residential (58) being the leading sectors. The report contains background on these projects, which represent more than 1.5 million square metres of gross floor space. There are also 21 mass timber manufacturing facilities across Canada.

One of the more prominent Canadian projects is Brock Commons Tallwood House, a student residence at UBC. The Commons is a test project of 18 storeys in height. When it was opened in July 2019, the building was “the tallest mass timber structure in the world” according to Wikipedia. The structure is 53 metres tall with a capacity of 404 students, a floor area of 15,120 square metres and is considered a “hybrid” in that it uses some concrete and steel in the construction.

Two other projects of note that are in the works are the Academic Tallwood Tower (ATT) at the University of Toronto and the Earth Tower to be constructed in downtown Vancouver. The ATT will be a 14-storey hybrid made of mass timber and concrete. The Earth Tower will be 37 storeys in height and could be the tallest mass timber structure in the world when completed.

As conceptualized, the Canada Earth Tower in Vancouver will be the world’s tallest hybrid mass timber building.

James Hobson:

PUTTING THE COOL IN ENGINEERING

James Hobson, a.k.a. the Hacksmith, created his YouTube channel as a record of his inventions, innovations and gadgets that he has designed. Today it has almost 13 million subscribers. Hobson, who is never short of ideas, just the time to implement them, has taken that built-in customer base and expanded Hacksmith Industries’ ventures to include a retail store where shoppers can purchase miniature versions of his inventions and Hacksmith branded apparel. Hacksmith Industries specializes in taking fictional items from comics, video games and movies and making real working prototypes in order to share them with the world on its YouTube channel. Using this relatable medium, Hobson has taken the boring out of engineering and that gives him incredible satisfaction. “I’d say that’s the biggest benefit of the YouTube channel − basically, inspiring youth around the world to go into science,

technology, engineering and maths by showing how cool it is to be an engineer. Kids say they didn’t know that was what engineering could be, thinking it was some boring thing. I feel we’re kind of doing the same thing for today’s generation as MythBusters did for my generation.

“I like keeping this idea of an industry that is the cool place to work. A lot of fans say ‘my dream is to work for you’ and that’s really great. I never imagined that when I started.”

Best-selling butane BBQ starter fashioned after the light saber.

Hobson has long been fascinated with engineering and as a teenager he knew it was the right career for him. “When I took tech class in high school, I learned that that’s engineering and then it was a pretty easy choice.” Ian Hillier, who would later join him at Hacksmith as co-founder and COO, was also in that tech class. “We went to high school together, college together, and worked on projects. When I started this business, he joined me very quickly after I quit my job,” says Hobson. The engineering bug stuck and Hobson went on to Conestoga College where there were lots of opportunities for hands-on projects. He graduated with a Bachelor of Engineering - Mechanical Systems Engineering. It’s been an adventure ever since.

Editor’s note:

MythBusters was a television show in the early 2000s wher e the hosts used elements of the scientific method to test the validity of rumours, myths, movie scenes, adages, Internet videos, and news stories.

At the end of 2020 Hobson decided to do a full series on making “We did, I think an eight-part video series building all the parts

The business of YouTube

Between operating a successful Etsy account, writing for Hackaday and working full-time in an engineering position, Hobson’s plate was stacked after graduating. The Etsy business selling laser engraved cutting boards was one of the side hustles he continued when he started the YouTube channel.

“It paid the bills while the YouTube channel grew,” recounts Hobson. “That was part of the reason I quit my job, because basically between trying to do YouTube, working full-time as an engineer, doing the laser engraving business on the side and doing the academic writing, I was burning the candle at both ends. I had about six months maybe of savings, so I had six months to make it or to crawl back to an engineering job. Luckily, between Hackaday and the laser engraving business on Etsy, I was able to make enough money to survive.”

Hobson attributes some of Hacksmith’s success to his approach to running the channel as a business. “Lots of big YouTubers have lots of followers, but they never really built up a team or reinvested as much back into the channel. And because of the nature of what we do, which is engineering, we built it more like an engineering business. We’ve built up a team and are invested in building up the spec facility and having all the tools and resources. We have basically become a skunk works − being able to make anything under one roof.”

On the Move

Hacksmith Entertainment is in the process of moving from its current site in Waterloo, ON to a 15,000-sq. ft. site with 18 acres in Cambridge, ON where they plan to grow the business. “The new property has lots of outside outdoor space for projects and whatnot. And we’re planning a 30,000-sq. ft. expansion,” says Hobson. “The acreage will allow for some more MythBusters-level projects. You can go out to the field to test a cannon or something. We can’t do that right now because we’re in the middle of an industrial district. Having that space, I think, is going to be the next paradigm shift for the business, which will be the second big shift because the first shift was moving out of my garage into a real facility 10 times the size.

“The property is called HERC and it stands for Hacksmith Engineering Research Campus. The nature of even having an acronym as your business name adds curiosity. When you make it look cool and you have an acronym, people ask: ‘What is that?’”

Ideas for the new location include large art installations, creating a collaboration hub, operating summer camps, and building a soundstage, a priority for Hobson. “Once we have that soundstage built, I wouldn’t mind looking into buying a decommissioned fighter jet and modifying it a bit and just parking it on the roof. Because if you park a plane on a roof, suddenly people are asking: ‘What’s that building? Why is there a plane on the roof?’ It is an easy way to make your building cooler than your neighbours’.”

At the end of 2020 Hobson decided to do a full series on making all of the Mandalorian’s (a Star Wars Disney Plus television character) different gadgets and armour. “We did, I think, an eight-part video series building all the parts such as the flamethrower, the blaster, the sphere, the armour, the helmet and the jetpack.”

Hacksmith followed that up with The Bounty, a 25-minute short film it did in collaboration with a local production company. “The Bounty is pretty cool because to me it feels like almost the same quality as the Disney Plus Series, which obviously has a lot more money and production quality. But it was a fun experiment. It didn’t get that many views on YouTube because it was kind of out of left field for us. People weren’t expecting a short film, but it still has over 1.6 million views, which is good,” says Hobson.

TOOLS AND TECHNOLOGY

TAKE SOME OF THE PAIN OUT OF RENOVATIONS

It is often said that the two most important rooms in a house are the kitchen and bathroom as they are used and featured most frequently.

Kitchen and bathroom remodels continue to be two of the best investments homeowners can make. We will add one more room, and that will be the mechanical room as these sometimes need updating as well.

When it comes to plumbing updates, we should also include the outside water service and building sewer.

TECHNOLOGY AND DESIGN TO THE RESCUE

It is very difficult to estimate renovations as each one is unique and has its own complications to update it to current code. One might ask how much time to allow for labour as most plumbers have different speeds. Now if you have a cost-plus job, it’s a plumber’s heaven on earth, but some plumbers take advantage of this, hence this is not fair to the customer. On the other hand, if you have a customer who keeps changing their mind and they have no general contractor in charge, it is better off being cost-plus, otherwise the plumber may be taken advantage of.

The ideal situation is having a good general contractor running the job with plans, and then you should be able to quote most of it. How would you quote and do a renovation like this? If the plans are accurate, the plumber basically would have to have a good knowledge of the plumbing code and some advice on the building code. My first approach would be to figure out time to gut everything unless the contractor is taking care of that. If the contractor is taking care of it then make sure he knows where and what lines to properly cut and cap. After the space has been gutted, it is a little easier to visualize what to do.

IS THE WATER SERVICE UP TO THE TASK?

Let’s start with the outside services. I met with the city’s chief plumbing inspector and his senior inspectors again to go over codes, so we are on the same page. Their message for me was to tell my classes of apprentices they make sure to inform customers of upgrading water services. This is especially true when a small house is being renovated into a large one. People often add one or two bathrooms and another laundry. Once you exceed 16 fixture units

Three-dimensional technology has changed the renovation experience.

of water volume (table 2.6.4.3. SIMPLIFIED METHOD), the water service must be upgraded from ¾ in. min. to 1 in. or 1 ¼ in. in size.

This means the city or a private company indemnified with the city would have to upsize the city water service on the city side of the property line at the customer’s expense. This price could range anywhere from $20,000 to $44,000 (prices a year before COVID) depending on the landscape. That’s just the tail piece, you still have to upsize the service through the front yard and into the house. As you are changing the water service, it is expedient to also change the old black coal tar or bituminized fibre pipe, clay tile, or cast iron building sewer. I have changed many of these. The old way was to allow for a front yard excavation and breaking out an inside hole in the concrete floor in the basement. These prices varied depending on length of front yard and what was in the way. Now with new technology we can sometimes pull a new water line and sewer line with just two holes, one outside and one inside. This proves to be more economical than overhauling a front yard and or garage front pad.

WHAT KIND OF HEAT?

Now let’s go to the basement mechanical room. Let’s say the renovation is making the house 1.5 times larger. You added two bathrooms and upgraded two bathrooms and a new kitchen was in the mix. You will need more hot water. Back in the day we added another normal 40 US gallon gas HWT in series and that did the trick.

Today there are all sorts of options. You could do the same thing, which would now cost at least $1,000 to $1,200 compared to $500 25 years ago. Or you could opt for a wall hung hot water exchanger, which is great for continuous hot water, that’s an additional $2,000 to $3,000. You could use some larger electric hot waters that are LEED-type energy efficient tanks and they range from $1,500 to $5,000. The more expensive options are typically more energy efficient over the long term.

As for heating upgrades, it depends if the customer wants forced air heating, a geothermal heat pump or hydronic heating. I’m not going to throw out general pricing on heating as there is such a variety of options. That being said the geothermal and hydronic infloor heating would be the most expensive but also the most economical over the long term.

Forced air heating is the cheapest, but once again in the winter you then have dry air blowing through the house, or one can install a humidifier to offset this problem. Adding a bigger furnace to augment heat for the extra space is something plumbers/gasfitters are qualified to do in Alberta, yet they will still need a qualified HVAC specialist to install the duct work beyond the gas, supply and return plenum. Speaking of the gas line, it will probably need upsizing also. Back in the day this was a pain as we did this in black steel piping, which required more time and space to install. Now it is much quicker as we can upgrade with yellow gas tite flex, which doesn’t require threading. Typically, people like to add a gas fireplace or two to their renovation.

Many people are concerned about how safe their drinking water is and how it tastes. This has led to advancements in reverse osmosis systems for residential. The old reverse osmosis systems used to require up to 10 gallons of water to get just one gallon of clean tasty water. Now the new systems use only one to three gallons of water to produce one gallon of reverse osmosis water.

MODERN KITCHENS AND BATHROOMS

Finally, let’s get to the show off stuff. I used to hate doing kitchen renovations, usually the architect and/or interior designer had no idea about the hidden mechanical and this caused major problems. Of course, this is where my love of new technology comes into play. Three-dimensional technology has changed everything. You can now see the renovation in advance, which helps greatly with the mechanical system design.

It shall be rated for the same size of pipe to which it is connected to

Most kitchen renovations have a kitchen island in the design. People love their kitchen islands complete with new in-counter sinks, fancy taps, stainless steel dishwasher and even in-counter ranges. Reverse osmosis is also an option for tastier water. Back in the day kitchen islands were a pain in the butt, but (no pun intended) now it is much cheaper and easier. Now we can legally use an air admittance valve (cheater vent) instead of an island vent, which required a lot of collateral damage (AIR ADMITTANCE VALVES Section 2.5.9. of the NPC).

The use of an air admittance valve on the right instead of the traditional island vent, definitely saves time and money.

EVERYBODY IS IN THE KITCHEN

Most people like to entertain in a beautiful kitchen. The stove is an integral part of that, with gas ranges being popular with those who love to cook. Whatever location the gas stove is in, whether it be in the wall or in an island or floor-standing, it is not too hard to extend a new gas tite flex line to it depending on the BTU gas rating of the range. The actual installed price of the appliance can be costly.

There are many different jacuzzi style tubs, and most new bathrooms are four or five piece bathrooms with separate jetted tub and showers. Even the bidet is making a big comeback as part of a toilet seat.

I would say the main difference in regard to modern bathrooms and

are the energy and water saving fixtures. They may cost more but they use less power or water.

HOW TO CHOOSE BETWEEN PNEUMATIC AND MECHANICAL PIPE PLUGS: FOUR FACTORS TO CONSIDER

In 1953, while working on an institutional job, Lloyd Cherne vulcanized a tire’s Schrader valve to a child’s inflatable rubber ball to create the pneumatic plumber’s test plug.

Since their inception nearly 70 years ago, pipe plug offerings have expanded to include testing, maintenance, and repair equipment for Canada’s plumbing and municipal sewer markets, and are offered in two types: pneumatic and mechanical, covering a range of pipe sizes.

Mechanical cleanout plug

But the question remains: How do you decide between pneumatic and mechanical plugs? There are four questions or factors that will likely impact this decision. Once you have determined the I.D. of the pipe you need to plug, what you need the plug to do, the back-pressure the plug needs to withstand, the media that needs to be blocked, and how long you need to keep the pipe plug in place, you can determine which plug to use based on your findings.

1What is the inside diameter of the pipe you need to plug?

The first step in choosing a pipe plug is determining the pipe’s I.D. (inside diameter). It’s important to check the I.D. of the pipe to be plugged and match it to the usage range of the plug to make sure it will work in the intended pipe.

Pneumatic plugs come in sizes ranging from 1 in. (25.4 mm.) to 96 in. (2438.4 mm.). Plumbing and municipal sewer workers can use them for blocking, bypassing or redirecting effluent, or conducting line acceptance or leak-location testing using air. Pneumatic plugs are designed to fit one pipe size or multiple pipe sizes.

Mechanical plugs are available in sizes ranging from .39 in. (9.9 mm.) to 18 in. (457.2 mm.) and do not need to be inflated. They are expanded to fit tightly within a pipe or open mechanically. Most only require hand-tightening.

PNEUMATIC PLUG SAFETY TIPS:

• Never enter the danger zone

• Monitor the placement and pressure of the plug during operation

• Clean with mild soap and water

• Store the plug in a dry place, below 110ºF

2What do you need the plug to do?

Pneumatic and mechanical plugs can be used for various purposes. To determine which plug to use, you have to nail down the purpose of the plug by asking: do I need to block a pipeline or an opening; bypass effluent that is running through a live pipeline; pressure test a new pipeline before placing it into service; or test a pipeline already in service for leaks?

As mentioned above, pneumatic plugs are used for blocking, bypassing, conducting line acceptance, or leak-location testing using air. Most mechanical plugs are designed for blocking. However, there are mechanical plugs available with or without a bypass that can be used for bypassing or air testing.

What is the point of access size you need to install the plug, and what is the maximum back pressure the plug must withstand?

The size of the point of access into which you need to install the plug will likely impact the plug required for the job. Back-pressure is the pressure (air or liquid) in front or back of the plug that it must restrain or hold back.

The total force exerted on a pipeline plug is directly proportional to the pressure and the pipeline area. It’s important to check the back-pressure rating on the plugs to ensure the pressure you need to block does not exceed the plug’s capabilities.

The type of plug needed will depend on the media the plug needs to block; for example, air, water, sewage, or something else.

Pneumatic plugs:

Pneumatic plugs are meant to be used in short-term applications.

If a pneumatic plug needs to remain in place for longer periods, its inflation pressure must be checked every four hours and adjusted as required.

Pneumatic plugs can be inflated with air, water, or inert gas (nitrogen). It’s crucial never to overinflate, or under-inflate plugs.

When pneumatic plugs are in use for safety reasons, the work area has to be cordoned off so that nobody gets in front of the plug. For this reason, an extension hose must be used to inflate and deflate pneumatic plugs from a safe distance.

Mechanical plugs:

Mechanical plugs do not need to be inflated. They are expanded to fit tightly within a pipe or open mechanically.

Most mechanical plugs only require handtightening.

Mechanical plugs are the correct choice for long-term or permanent installations. Some offer specialized features such as chemical resistance, the ability to lock in place, or are designed for specific applications, such as pipe hubs and clean out coverings.

It’s crucial never to overinflate, or under-inflate plugs.

What media does the plug need to block, and how long does it need to be kept in place?

Heating season prep applies to you and your stuff

Two things come to mind regarding preparation for the upcoming heating season. The first concern is you. Are you ready physically and mentally? I don’t mean to sound like your mother, but are you eating well, staying in shape and avoiding too much late-night partying? You owe it to yourself and customers to show up ready for the challenge.

There certainly is no lack of online info to help you choose the best diet; find the right plan and foods that work for you. When you are on the road take the time to stop for lunch or snacks throughout the day. Coffee shops on every corner make it quick and easy to stay hydrated. They do sell other beverages, which are perhaps healthier than coffee.

If the term yoga frightens you, check out some basic stretches to start and finish the day. Your dog does them regularly so there must be something to it. As with anything these days, there are plenty of online videos if you want to go to another level with stretching and relaxation tutorials. Be happy, stay engaged with your fellow workers and customers. If you hate getting up early and going to work, it’s time to find another occupation. One-owner shops can easily suffer work fatigue when the season gets busy.

Prepping for your financial health

Is the juice worth the squeeze? Do you feel you are in a healthy position wagewise? Things aren’t getting cheaper. With plumbing and HVAC skills, you should be able to write the exact deal you need to provide and save for your family. Perhaps your body is worn down from years of lifting, pulling and stressing. It may be time for a side move in the industry. Virtually every factory rep company, wholesaler and manufacturer is looking for the right people to grow its team.

Participate online with a chatroom that fits your style. Stay abreast of what goes on in other areas of the planet by following companies in the industry on LinkedIn and reading trade publications.

Getting the rig ready

Unquestionably a part that is the most fun for many contractors is getting the shop and rig ready for the busy season ahead. A clean, organized workspace and service truck crosses between the mental aspect (reduced stress) and the ability to be efficient and profitable. Knowing what you have and where it is speeds and smooths out the process of installing and repairing.

Commit to a seasonal cleanout of your workspace and vehicle. Make the switch from cooling parts and equipment to heating or cold weather specific

Stay in touch

What about your communication equipment? It’s a digital world and one key piece keeps you in the loop with your company, customers, factory support and family. Your phone can be one of the best tools you own. You need one with a good camera for documentation. Check out adapters such as infrared (IF) cameras to extend its ability to document jobs.

I see drones being used more and more for documenting installations such as geothermal fields, radiant layouts and utility line installations. Are you doing commercial work? Send the drone up to check out rooftop work, get an idea of what may be needed before the crane shows up.

Tool rental is another thing to consider if you cannot spring for the latest in press technology, for example. Many of the wholesalers I visit have a selection of press equipment for rent or loan, when you start looking at larger sizes, two in. and up, the cost may be out of reach for the one-man shop. Press technology can save, and make money on those emergency repairs.

Supply issues

How much inventory can you afford to keep on hand? We all know how hard it is getting supplies and product these days. You have a good idea of what the typical consumables are for your work area. I know of a local HVAC contractor who took out a second mortgage to load up on furnaces and AC equipment when he saw the shortages coming. It was a risky move, but he made some good coin selling not only to his customers but also to competitors. It could be as basic as loading up on glycol or 40Va transformers when they are available. Even better for cash flow, coordinate with your wholesaler to ensure you’ll have the equipment you’ll need this season.

“I know of a local HVAC contractor who took out a second mortgage to load up on furnaces and AC equipment when he saw the shortages coming. It was a risky move, but he made some good coin selling not only to his customers but also to competitors.”

Look ahead

I suppose no article of mine would be complete without a mention of training. It should never end at your business. Technical training is always top on my list. Whether it is online courses on how to service or program the equipment you sell and service and/or expos to see and learn about new products, it is time well spent. I don’t know of anyone who doesn’t learn something new and interesting at a good tradeshow, so snoop around, see what is coming your way.

Sometimes low on the list but necessary are seminars and training on how to run your business, account for the money, and demystify insurance and retirement plans. These are areas of business we all need to stay on top of. Retirement and investing are especially important areas to focus on, particularly with this aging workforce.

So, start your list, in your head or on that smart phone, and get going today on these sound suggestions. A job started is a job half-finished.

WORKING WITH R400-SERIES REFRIGERANTS

Approximately 30 years ago, several refrigerants emerged as alternatives for chlorine-containing CFCs. Just a few examples of some of these alternatives are R401A, R401B, R402A, R402B, etc. The majority of these refrigerants were in the R400-series category and are also referred to as zeotropic refrigerants. These refrigerants were blends of pure (single) refrigerants such as R22, R124, R125, R152a, R290, etc. Each of these individual refrigerants have their own pressure-temperature characteristics. So, for a given pressure, these refrigerants change state at different temperatures. For this reason, mixing refrigerants such as these will result in a temperature glide within heat evaporators and condensers as the refrigerant within evaporators and condensers changes state.

OTHER FACTORS

To some extent, the maximum theoretical temperature glide will depend on the refrigerant with the lowest saturation temperature and the refrigerant with the highest saturation temperature. However, there are other factors such as the amount of each refrigerant in the blend.

For each pressure value, an R400-series refrigerant has both a bubble point temperature and a dew point temperature. The bubble point can also be referred to as the saturated liquid temperature. Similarly, the dew point can also be referred to as the saturated vapour temperature.

In the condenser, all of the temperature glide that an R400-series refrigerant exhibits, will be present. This means that after the hot vapour from the compressor is desuperheated, it reaches its dew point temperature. As the refrigerant continues to reject heat, it changes state from a vapour to a liquid. Meanwhile the temperature gradually drops from the dew point temperature to the bubble point temperature. Once the bubble point temperature is

reached, there will be no more vapour present. At this point, any further reduction in the heat content of the refrigerant will result in subcooling.

This brings up an important point about checking superheat and subcooling values in a system. Either the dew point or bubble point must be used as the reference temperature. However, if the wrong reference temperature is used, the amount of superheat or subcooling that you read will be off by the amount of temperature glide present.

For example, if we want to determine the amount of subcooling present in a liquid line, we will first read the pressure. For this pressure value, there are two reference temperatures. Again, these are the bubble point temperature and the dew point temperature. When determining subcooling values we must always use the bubble point as the reference temperature in order to obtain a correct value.

Many of the printed pressure-temperature charts list only bubble point values in the higher temperature range. For example, they may list bubble point temperatures of 50°F and higher. Similarly, only the dew point temperatures are listed below

Phil Boudreau Phil leads special projects and provides national technical support for Bitzer Canada Inc. He can be contacted at pboudreau@bitzer.ca.

50°F. With these types of tables, it is less likely that the technician will use the wrong reference temperature. In other cases, some tables and refrigerant apps for mobile devices provide both the bubble point and dew point temperatures. Therefore, the technician must choose the correct value.

Here is an example to confirm the correct procedure for checking the amount of subcooling present in a liquid line containing R449A. The pressure reading that we measure on the liquid line is 207.8 psig. The temperature that we read is 82°F. According to the mobile app, the dew point temperature is 98.2°F

and the bubble point temperature is 90°F. Since we are checking a subcooling value, we must use the bubble point as the reference temperature. Now, we simply subtract the actual temperature that we read on the thermometer, from the bubble point temperature. This results in a subcooling value of 8°R (90°F – 82°F).

Note that if we were to use the dew point to determine the subcooling, we would come up with a value of 16.2°R (98.2°F – 82.0°F). This confirms that by using the wrong reference temperature, our subcooling value will appear to be much higher than what we actually have. Specifically, the subcooling will be off by the amount of temperature glide present at 207.8 psig.

It is important that the technician can correctly determine the evaporator, compressor suction and compressor discharge superheat. On page 54, is a similar example of a superheat calculation. For this

IMPORTANCE OF TECHNICIAN’S DIAGNOSTICS

temperature is 15.3°F. Since we are checking a superheat value, we must use the dew point as the reference temperature. Now,

simply subtract

temperature from the actual temperature that we read on the thermometer at the outlet of the evaporator. This results in a superheat value of 11.1°R (36°F –24.9°F).

Note that if we were to use the bubble point to determine the superheat, we would come up with a value of 20.7°R (36°F – 15.3°F). This confirms that by using the wrong reference temperature, our superheat value will appear to be much higher than what we actually have. Specifically, the superheat will be off by the amount of theoretical temperature glide present at 51 psig.

Superheat in a liquid containing R449A

The term theoretical temperature glide refers to the maximum amount of temperature glide present for a given pressure. In the evaporator, the refrigerant never enters at the bubble point. This is because some of the refrigerant flashed to a vapour in order to reduce the temperature of the bulk of the liquid entering the evaporator. Therefore, the actual temperature entering the evaporator (after the expansion valve), will be higher than the bubble point temperature.

When checking superheat and subcooling values, it is also very important to ensure that the pressure gauge and thermometer that we use are of the correct type for the application, are accurate and calibrated.

There are many electronic manifolds that will read the pressures and temperatures on both sides of the system while conveniently indicating the superheat and subcooling values. Although this simplifies the process, it is important that technicians know how to do this manually.

Busting common heat pump misconceptions

Arecent survey conducted on behalf of BC Hydro found many British Columbians are hesitant to install a heat pump because of lack of awareness and misconceptions about how they operate.

“Many British Columbians are missing the benefits of a heat pump including thousands in rebates and significant reductions in carbon emissions because they are sticking with what they know,” says Kevin Aquino, BC Hydro spokesperson. “We want to dispel the more common heat pump misconceptions so British Columbians can make informed decisions about the best way to heat and cool their homes.”

Just over a quarter of British Columbian homeowners expect they will have to replace their natural gas furnace within the next five years, and almost a quarter (24 per cent), said they are unlikely to consider installing a heat pump, with another 14 per cent saying they are unsure. Part of the reason for the hesitancy is a lack of heat pump knowledge. For example, 30 per cent of those who are not likely to replace their natural gas furnace with a heat pump said it is because they do not know enough about heat pumps.

“Heat pumps have been around for a long time and, in the past did not work for everyone, but recent advances in their technology have made them the perfect alternative to heating with gas or fossil fuels for most British Columbians,” Aquino adds.

Misconception: Heat pumps are costly to operate. Sixteen per cent of British Columbian homeowners think so.

Fact: While costs depend on many factors, including type of system, size and location of a home, heat pumps can be 300 per cent more energy efficient and much less expensive to run than electric baseboard heaters, and comparable to the cost of natural gas heating. With BC summers getting hotter because of climate change, heat pumps can also cut down on cooling costs. They are more efficient than portable air conditioning or window units, which are on the rise in BC, and can reduce customers’ carbon footprints when switching from a natural gas system because they use hydroelectricity.

Misconception: Heat pumps do not work in cold weather. Eighteen per cent said they believe heat pumps do not work well in the cold.

Fact: In recent years, technological advances have allowed heat pumps to perform in very cold temperatures – some can provide adequate heating in temperatures as low as -30°C. In very cold climates, supplemental heating from other sources like electric baseboards can help.

Misconception: Heat pumps are expensive. More than 30 per cent of British Columbian homeowners who have not considered installing a heat pump said they think it is too expensive to buy and install.

Fact: While some higher-end models can cost a bit more, the average cost to buy and install a system for small homes is about $7,000 and about $16,000 for larger homes. In many cases this is comparable to costs of installing both a gas furnace and central air conditioning. Rebates are offered in many jurisdictions. For example, BC Hydro offers up to $3,000 in rebates for switching from a fossil fuel-based system, which can be combined with provincial and federal rebates for a total savings of up to $11,000 on cost and installation.

Misconception: Heat pumps are noisy and take up a lot of space. Eight per cent of British Columbian homeowners said they think heat pumps are noisy, and seven per cent said they take up a lot of space.

Fact: Most outdoor units have a sound rating around 60 decibels, which is comparable to the sound of light rainfall. Indoor units are even quieter and generally between 18 and 30 decibels. Ultra-quiet models are also available. Air source heat pumps require very little room, and the inside units are compact and mounted on walls.

By Carolyn Cooper

Name: Andrew Hoerner Nickname: The Professor Company: Hoerner Heating & Plumbing Service Inc. Job title: Owner and senior technician

Born/Lives in: Toronto, ON Age: 58 Spouse: Tracey Children: Triplets Alex, Emma and Dylan, 22 Pets: A Havanese and Shih Poo named Lupin and Panda

Andrew Hoerner: Committed to growth

When Andrew Hoerner was a plumbing student, he received some business advice that he turned into a challenge. “A teacher once told me ‘when sons take over their father’s business they run it into the ground,’” he recalls. “I really took it to heart and aimed to prove them wrong.”

Hoerner worked with his father for 10 years, beginning when he was just 14, and took over Hoerner Heating & Plumbing Service Inc. in 1991. Not only has the company remained successful, it’s grown significantly in the past three decades, and today does residential servicing throughout some of Toronto’s most affluent neighbourhoods.

But Hoerner admits that the early years were difficult. “I was not prepared to own and operate a business. I knew nothing about profit and loss statements and all that, and how to calculate how much to really charge to make a profit. So mentally I was ready for it but I don’t think I was educated enough to apply the principles that are required to run a profitable business. I didn’t learn that till we became part of Nexstar and Plumbers’ Success International.” He adds that his wife, Tracey, has also been a key part of the businesses’ success. “She’s the driving force,” he laughs. “She’s the one who comes up with innovative ideas, which I think are crazy, but then we put them into play, and it works out great.”

The older Toronto neighbourhoods have a lot of tree root infiltration, so Hoerner Heating does lots of drain repair and replacement, as well as residential repairs. The company is also busy with water heater replacements and installing plumbing systems, boilers and tankless water heaters.

“There have been a few calls now for hybrid electric water heaters,” says Hoerner. “They’re not cheap, but people who are into that seem to want it, and don’t mind paying a little extra because they’d rather not use natural gas to heat their hot water. We’re doing an installation right now of a Viessmann boiler, and we really pride ourselves on the installation, and all the add-on equipment, like dirt magnets and air separators – we try to do everything top notch and not leave anything out.”

Because the company continues to expand, Hoerner says space has become a new challenge. “Our shop is fairly big but it’s too small for how much we’ve grown, and we have 11 trucks in the field, so it’s tricky,” he says, explaining that most of their techs take the trucks home, and arrive for work in the morning in intervals. “So, it would be nice to have a larger property where we could store some of the trucks, have a garage and some offices.”

A POTENTIALLY UNHEALTHY MIX

Hydronic radiant heating is a comfortable and efficient technology for a range of buildings, from residential applications to large commercial and industrial facilities. In most projects, it is possible to meet the heat loss of buildings through a heated floor using relatively low-temperature heated fluid, often under 120˚F (48˚C), even at design load or peak demand.

This gives radiant heating systems the flexibility to work with a variety of high-efficiency heat sources, such as low-temperature condensing boilers, geothermal water-to-water heat pumps, airto-water heat pumps, and solar thermal collection systems.

In certain cases, especially with low-load hydronic radiant heating distribution systems, domestic water heaters have been used as the source of warm water, subject to local code requirements. Typical applications of this type of heat source include special dual-purpose water heaters, which are intended to supply both hydronic space heating and hot domestic water, and are designed so that the heating water and the domestic water do not mix. These domestic hot water (DHW) heaters are sometimes described as “combi” or “segregated” and they typically utilize an internal heat exchanger to prevent mixing of the potable water with the hydronic heating water.

When combined hydronic and potable systems are construct ed whereby the potable water travels through hydronic heating distribution units such as fan coils, radiators and radiant piping layouts, and components such as valves, circula tors, or manifolds, potential health and safety issues may be created. These potential issues include drinking water safety, Legionella and biofilms, and corrosion and equipment life.

The potential for these issues prompt ed the Plastics Pipe Institute to recom mend that combined potable-hydronic systems, where the mixing of hydronic water with potable water may occur, should be avoided.

Alternate potential heat sources for small hydronic heating systems are available.

PROTECTING THE SAFETY OF DRINKING WATER

In 2019, Health Canada published new maximum acceptable concentrations (MAC) for lead in drinking water, introduced new sampling protocols and changed the point of compliance from the drinking water distribution system to the customer’s tap. Components which contact potable water must be certified to standards such as NSF/ANSI/CAN 372 Drinking Water System Components – Lead Content. Similarly, plumbing components must be tested and certified to NSF/ANSI/CAN 61 Drinking Water Components – Health Effects to ensure they are safe for drinking water.

Some hydronic heating components are not intended or certified to be used for potable water. Examples include certain radiators, pipes, fan coils, fittings, balancing or mixing valves, and distribution manifolds. Such items aren’t necessarily marked as “Non-Potable”; the absence of a “Potable Water” or “PW” mark may be the only clue that these components are not suitable for contact with potable water.

Legionellabacteria

Alternate potential heat sources for small hydronic heating systems include segregated dual-purpose water heaters with internal heat exchangers, or the use of external heat exchangers to separate the potable water from the hydronic water.

Therefore, if these components are installed so that domestic water flows through them and then returns to a potable water outlet, this type of installation may violate regulations regarding the approval of components for drinking water safety, or regulations requiring so-called lead-free components intended to contact potable water, or both, and may contaminate drinking water.

The reasoning behind a recommendation against mixing hydronic heating water with potable water in combined systems

MINIMIZING RISK OF LEGIONELLA

According to the U.S. CDC, Legionnaire’s Disease, a type of severe pneumonia, is caused by breathing in small droplets of water that contain the bacterium Legionella pneumophilla. Legionella has been a topic of much research in recent years, with experts in the public health and plumbing fields focusing on piping designs that minimize dead-legs and stagnant water. Research indicates that Legionella can grow in water between 68°F and 120°F (20°C to 48°C), with an ideal growth range of 85°F to 110°F (29°C to 43°C).

In a typical residential plumbing system, with 200 to 300 feet of hotwater piping, disinfectants in treated water can control the growth of Legionella. Hot water is normally delivered to outlets quickly, and the age of the water is not a concern, even though drinking water disinfectants can dissipate quickly after being exposed to heat, such as in a water heater. Some level of disinfectant normally remains until water is delivered to a fixture.

However, if the plumbing system is connected to a hydronic distribution system, such as a radiant heating system, this can lead to a large volume of water. Over time, this water could contain little to no disinfectant at the ideal temperature range for Legionella growth. When the heating system turns off, there could be a significant volume of warm stagnant water sitting in pipes, fan coils, and other hydronic components. When the heating system turns on due to a call for heat, that stagnant water will re-enter the domestic hot water heater, and then travel through the plumbing distribution system to an outlet.

Water becomes aerosolized in a shower or near an aerated faucet and is

easy to inhale. This is a potentially dangerous situation for people who are susceptible to this type of bacteria, as it can allow Legionella to enter the lungs.

During periods of inactivity such as summer, the water in heating components might be stagnant for weeks or months. Although the water is at or near ambient room temperature, and Legionella will grow more slowly, it does not die. Further, stagnant water has been shown to allow the growth of biofilms inside piping components and appurtenances.

To help prevent this, some codes require a means to prevent the stagnation of hydronic water by cycling or flushing the contents at least every 24 hours, such as with a timed circulator. However, if the timer used to activate this circulator fails or is deactivated, or if certain zone valves remain closed, complete flushing doesn’t occur.

Studies show that flushing with hot water to effectively kill Legionella requires a temperature above 160°F (71°C) throughout an entire piping network; at lower temperatures, some bacteria can remain protected inside biofilms. However, supplying water at this temperature through radiant tubing embedded in concrete may damage both concrete and flooring, so this is not a recommended procedure. Also, setting a water heater to a temperature above 130°F (54°C), even during short time periods, can create very hazardous conditions to building occupants due to the risk of scalding.

In recognition of the potential risk of creating an environment promoting the growth of pathogens in a combined potable-hydronic system, the 2021 edition of CSA B214 Installation Code for Hydronic Heating Systems added new restrictions on the use of combined systems. These include limiting the total length of the hydronic piping network to 50 ft. (15 m), the total volume of water in the hydronic system to 13.1 US gallons (50 L), and the minimum supply temperature to the hydronic system of 140°F (60°C).

Some hydronic components can be corroded or otherwise damaged

and disinfectants such as chlorine or chloramines

For example, an iron-body circulator that

in

system, but is actually

system, could rust when exposed

attacked

and eventually leak; or plastic tubing that

certified for hydronics but not for potable water might not be compatible with

chlorinated water and might fail prematurely.

DEFINING DISTRACTED DRIVING

A good working definition of driver distraction is “an internal or external factor that takes your eyes or mind away from the road.” In short, it’s anything that takes your focus away from driving. Driving-related distraction can be organized in two groups:

1. Conscious distraction. Decisions we make, like reaching for a cellphone or tuning the radio.

2. Unintentional distraction. Mental lapses that nobody intends to make, such as falling asleep at the wheel or letting their mind wander at a crucial moment.

Why you should care about distracted driving

In some parts of Canada, the number of distracted driving fatalities has now surpassed the number of impaired (drunk or drugged) driving fatalities. That statement from the Traffic Injury Research Foundation says it all. The frequency and potential severity of vehicle collisions places driving in the worst corner of any risk matrix. Add distraction to the mix and driving becomes the riskiest thing we do every day. The real issue isn’t what causes distraction, it’s that distraction compromises our decision-making ability and leads to mental lapses.

Everyone drives or rides in a vehicle. And that means distracted driving affects every single business in the world. Because no matter where a crash occurs − at work or off the job − it can affect drivers, passengers and pedestrians for weeks and months afterwards. And employers pay the price in lost productivity, reduced morale, and injuries to workers … or worse.

Beyond driving, distraction can still lead to costly outcomes, whether it’s rushing down stairs or taking focus away from power tools or other hazards. If you want to keep your people and profits safe you need to see distracted driving as a problem that goes way beyond the workplace.

CELLPHONES ARE ONLY PART OF THE PROBLEM

Most anti-distraction campaigns feature someone texting from behind the wheel. But data from the Fatality Analysis Reporting System suggests cellphone use is responsible for only 12 per cent of fatalities caused by distracted driving.

It isn’t a cellphone issue. It’s not even a driving issue, really. A person’s state of mind makes them vulnerable to distraction, and that can lead to poor decisions, mental lapses and a whole bunch of errors. The end result is taking eyes and mind off the task at hand.

Distraction comes in many forms:

• the radio, car controls, GPS, looking at street signs, passengers, and unexpected moving objects

• talking with someone else, listening to music, looking at a map

• smoking, eating and drinking

• a wandering mind or being lost in thought

These four sources aren’t enough to lead to distraction on their own. What causes you to become distracted by these things sometimes?

A person’s state of mind can make them more vulnerable to the sources of distracted driving:

• When we are rushing, we are more likely to think about why we are in a rush than to concentrate on driving.

• When we are frustrated, we are more likely to get distracted by something we see.

• When we are tired, we are less likely to maintain focus when we hear something unexpected. Perhaps the most dangerous cause of distraction is familiarity with the risk. People take unnecessary risks behind the wheel because they forget driving is incredibly dangerous. In a word, they become complacent.

Multitasking is a myth. When we “multitask” the brain actually switches rapidly back and forth between the two tasks. That requires a lot of mental work. And even basic, attentive driving requires numerous different tasks, from steering to monitoring speed to thinking about safe braking distances and looking out for pedestrians and other vehicles.

Eyes on task, complacency and driving without awarenessCodes vary by province

We’ve all had a feeling of being on autopilot during a drive − our bodies react automatically to external events (such as changing lanes when there’s a slow car ahead) but our minds don’t quite register it. These types of drives feel like they go by in a blur.

This is called driving without awareness and it shows the problem with saying, “Keep your eyes on the road.” Just because something is in front of you doesn’t mean you see it. Studies and common sense both suggest that as attention goes down, the chances of a car crash go up. It takes having your eyes and your mind on task to fight off the inattention and complacency that can settle in during a long drive. And that takes skills and practice.

Distracted driving is the result of human error

The pattern of distraction has a lot of steps: the states of mind that make people susceptible to distraction, the sources of distraction, the errors we make when we’re distracted.

But we can condense the entire pattern into two words: human error.

Cars and other machinery don’t lose focus. Humans do. And when our attention wanders, people get hurt. Any solution to distraction needs to be as comprehensive as the problem.

Keeping workers’ eyes and mind on the task at hand

We talked about how “a person’s state of mind can make them more vulnerable to distraction.” Fortunately, a person’s state of mind can make them more resistant to distraction too.

There are three crucial elements to keeping workers’ eyes and minds on the task at hand: knowledge of the problem, the skills to fight distraction, and reinforcement to build strong habits and keep skills and knowledge sharp.

The quickest and most effective way to learn and retain all three elements is to introduce training that provides personal safety and awareness skills as part of your safety program.

Knowledge

Employees need to understand distraction in practical terms. How does it affect them? What can they do about it? Here are a few ways to help them better grasp the problem and to truly believe in the risk of distraction:

1. Share the alarming stats, scope of the problem and root causes of distraction.

2. Share a personal story of your own about how distraction caused a close call so they can see that anyone is susceptible to distraction-related risk.

3. Ask workers to share a story about when they were driving and had a close call because they momentarily let their eyes or mind drift. This will remind them of how personally susceptible they are to distraction.

4. Disrupt their complacency with the risk. This is especially necessary for activities where the risk and familiarity with the hazard are both high. Get workers to talk about how they would explain the danger level to someone else such as their children.

5. Encourage workers to explain the distraction pattern in

their own words. Quiz people on which state of mind (rushing, frustration, fatigue and complacency) or which source of distraction (visual, auditory, manual and cognitive) they think is most likely to cause them problems.

Knowing is half the battle. The other half is the ability to act on that knowledge. Provide workers with the personal skills and reinforcement needed to defeat distraction.

Awareness Skills

There is always some sort of distraction nearby. People need the skills to maintain focus when the risk of distraction is compounded by their state of mind (rushing, frustration, fatigue and complacency) and amount of hazardous energy (walking versus driving).

People can recognize the physical symptoms of these states fairly easily:

• increased heart rate and feeling frantic = rushing

• feeling flushed or like your “blood is boiling” = frustration

• yawning, dragging feet, or feeling lethargic = fatigued But few people are able to take effective action when they notice these signs. That’s because most of us focus more on the problem than on how to deal with it.

Complacency is also a factor. Someone might notice they’re tired and, even though they know there’s an increased risk they’ll fall asleep, they choose to drive anyway because they’ve done it numerous times before without incident. Workers need the skills to recognize when they’re rushing or fatigued and they also have to know what to do about it.

Skills in Action

Discuss how to respond in certain situations by using “if-then” scenarios. This type of verbal planning is an easy and effective way to prepare employees for dealing with these states when they occur.

Ask employees which state they might encounter and ask them to explain what they’ll do to reduce it. Examples include:

• “If I notice I’m rushing to get somewhere then I’ll think to myself that it’s not worth the extra risk, and go at a normal pace.”

• “If I start to feel frustrated with other drivers then I’ll take a deep breath and try to cool off.”

• “If I catch myself yawning then I’ll remind myself to stay extra-focused and not take any extra risks to compensate for my fatigue.”

The signs of complacency can be harder to recognize in the moment. It is especially important to reinforce the knowledge, habits and rules that reduce the risk of mental lapses and poor decisions through repetition and motivation.

Bears, BBQ and business make for a memorable event

In-person CIPH ABC offers valuable insights, honours industry professionals

More than 275 delegates gathered at the Fairmont Jasper Park Lodge in Jasper, AB for the Canadian Institute of Plumbing & Heating’s (CIPH) Annual Business Conference (ABC). Some attendees at the sold-out event arrived ahead of June 19, the opening day, to enjoy the many activities available in Jasper Park and surrounding area.

Monday’s agenda included a captivating historic perspective on the area with a talk and slide show about the early days of travel in Jasper National Park by Karen Byers, manager with Jasper-Yellowhead Museum & Archives. The day’s agenda

On Tuesday, breakfast speaker Matricia Bauer of Warrior Women noted that the majority of work theories and workplace approaches across North America are based on Western paradigms that are not relevant to Indigenous values, beliefs, culture, and rights. “Decolonizing our workplaces means going beyond tokenism or the mantra of ‘treating everyone the same,’ to one where we actively acknowledge and support the self-determination of Indigenous people, including cultural, spiritual, and land connections,” said Bauer. She went on to describe practices that would help guide managers and business owners in this endeavour.

This new delegate captured the attention of some CIPH ABC delegates and sent others running for cover. The daring grizzly youngster was just one highlight of the opening day.

Keynote speaker Graham Sherman, co-founder of the hugely successful Tool Shed Brewing Company, shared why adopting a collaborative approach with competitors can actually be a healthier way to do business, leading to exponential growth and a loyal customer base.

As is the CIPH tradition, the ABC concluded with a formal dinner and entertainment. The operatic, pop and comedy-packed performance by Opera on The Rocks! was a fitting end to the event.The 2023 ABC will be held June 18 to 20 at the Delta St. John’s in St. John’s, NL.

Forces threaten to upend relationships

Distribution strategy expert Ian Heller brought delegates back to the present with his presentation Shift from Defence to Offence: eCommerce, Marketplaces, Sales Structure and Services. “Manufacturers, distributors, and their end customers face a dizzying array of forces threatening to upend relationships, and change the value equations for channel players,” said Heller. “This requires B2B companies to rewrite strategies and overhaul their business models.”

He addressed a number of issues of concern in the current business climate, including AI, the relevance of sales reps, manufacturers and distributor partnerships, and adding value to differentiate from pure product sellers. In the breakout sessions that followed, Heller asked attendees “How should you respond and adapt your company’s strategy to succeed in a fast changing and often bewildering business environment?”

Understanding the proper application of hydronic systems

Sidney Manning, provincial plumbing and gas administrator, municipal affairs – Government of Alberta addressed CIPH hydronics members at the Canadian Hydronics Council (CHC) luncheon on June 21. With the theme Shift to Celebrate – The Value of Collaboration, his session focused on regulatory application of CSA B214 installation code for hydronic heating systems and other items relative to the provincial and national application of hydronic heating systems.

Paul Stevenson, who was unable to attend, received the CHC annual Award of Merit. He served as EMCO Corp.’s profit centre manager in Victoria, BC, as well as a hydronics technical services specialist, before his retirement in April 2022 after 45 years with the same company.

Jerry Leyte, president and general manager of Viessmann Canada, is the 2022/2023 CHC chair.

Matt Robinson elected CIPH chair

Outgoing chair Bill Hooper (R) of Uponor with 2022/2023 chair Matt Robinson, VP Showroom Group, B.A. Robinson.

Matt Robinson was elected as the 75th chair of CIPH during the association’s 90th annual general meeting. He is the second Robinson to hold the position – his father Ross was chair in 2003/2004. Robinson is vice president of Winnipeg, MB-based Showroom Group, Robinson (A Division of B.A. Robinson). He was elected to the board in 2012, and in the past has served as a board member with the CIPH Calgary Region, as Calgary Region president, and on two CIPHEX West show committees.

CIPH technical consultant for codes and standards David Hughes (L) and Sidney Manning share a moment following Manning’s presentation. Manning quipped that regulators could use some loving.

Jon Leeson, vice-president, building mechanical market with Groupe Deschênes Inc., was elected chair of the wholesaler’s division and Garth Wallin, president and CEO, Blanco North America will lead the manufacturer’s division.

Ian Heller of Distribution Strategy Group shares insights into evaluating and responding to threats now and in the future at CIPH’s ABC.

The Right Water Softening Solutions

By Don Matt for your customers

Residential water softeners began appearing in North American homes in the mid-1900s.

Prior to in-home softeners, it was commonplace to use rain water as a final rinse to make laundry feel soft. The term “soft water” originated in advertising around that time to help consumers understand what these new water treatment systems would do in their homes. Today, most Canadian homeowners are familiar with the benefits of soft water as well as the costs of hard water ruining water-using appliances, plumbing fixtures and pipes.

Hard water, which is measured by the presence of calcium and magnesium in water, causes spots on dishes and glassware, and scale build-up in pipes, plumbing fixtures and water-using appliances. It also makes soap and detergent less effective, dries out hair and

Water hardness levels vary across Canada with the hardest water found in the Prairie provinces, southeastern British Columbia and the populous southern tip of Ontario and Quebec. northern Manitoba, Ontario and Quebec all have moderately hard water while central to southern Ontario, Quebec and the Atlantic provinces have slightly hard water. Select areas of British Columbia and Alberta are the only places in Canada with natural soft water.

Hard water can occur both naturally and as a result of industrial factors. Naturally occurring hard water is most prevalent in ground water sources originating in areas with limestone and thick topsoil. The primary industrial sources of hard water are the mining industry and inorganic chemicals.

Offering soft water solutions to your customers is an opportunity across Canada.

Hard water is measured in grains per gallon (gpg), parts per million (ppm), or milligrams per liter (mg/L) to show the concentration of hardness minerals in water. Water with concentrations of hardness minerals seven gpg and above are generally regarded as “hard.” Testing a homeowner’s water is the first step to helping them select the right water softener for their home.

The number of bathrooms and/or people in the home are also used to determine the correct size of the softener.

Ion exchange technology has been proven to be an effective way to soften water. Ion exchange is the process of replacing calcium and magnesium ions in hard water with sodium ions. Ion exchange softeners direct incoming hard water through a tank filled with synthetic resin beads charged with sodium ions. Ion exchange occurs when the calcium and magnesium ions in the water are exchanged with the sodium ions on the resin. Over time, the sodium ions on the resin are depleted and need to be replaced. The softener then pulls salt brine from the brine tank into the resin bed to replace the calcium and magnesium ions with sodium ions on the resin. The calcium and magnesium ions are sent to the drain and the resin is recharged to soften water again.

Remember to look for certified performance claims when selecting a softener for customers. International Association of Plumbing and Mechanical Officials (IAPMO) and Water Quality Association (WQA) provide testing to NSF/ANSI 44-2018 and CSA B483.1 for hard water reduction claims. Softeners that aren’t certified have not been third-party tested to ensure performance claims are accurate.

In recent years, we’ve seen the introduction of systems marketed as “salt-free water softeners.” While these systems use a variety of technical approaches to prevent hard water scale, they do not actually remove hardness minerals from water. In 2020, the WQA updated its glossary of terms to prevent use of the term “salt-free water softening” to protect consumers from misleading marketing claims. These systems are now marketed as “saltfree water conditioners.”

WATER USAGE DROPS TO LESS THAN A THIRD

While ion exchange has been used for nearly a century to soften water, the efficiency of water softeners using this technology has improved greatly over time. Today’s softeners use up to 75 per cent less salt and 64 per cent less water than traditional calendar clock water softeners. In addition to being better for the environment, the savings in money, time and convenience are significant for homeowners as well. For example, a mechanical meter softener set for a family of four using 60 gal/person/day of 30 gpg hard water will use about 25 bags of salt and 13,500 gallons of regeneration water each year. A high-efficiency softener for the same family, hardness and water consumption, will use less than 14 bags of salt and just over 4,000 gal of regeneration water each year.

Replacing an old, inefficient water softener is the number one source of new softener sales so don’t overlook the opportunity to talk to your customers about the benefits of upgrading their current softener.

THE BENEFITS OF PRE-SOFTENER TREATMENT

One of the newest trends in water softening today is adding carbon filtration as a softener pre-treatment on municipal water applications. In my last article (see Mechanical Business May/June 2022 at mechanicalbusiness.com), I noted the increased use of chlorine and chloramines in municipal water treatment. These disinfectant chemicals degrade softener resin by turning some of the resin beads into a jelly-like substance that no longer softens water. The softener resin is less effective and needs to be replaced far sooner. Removing chlorine and chloramines before they reach the softener is the best way to maximize the life of softener resin.

In 2018, the International Association of Plumbing and Mechanical Officials (IAPMO) introduced a new standard: IAPMO/ANSI Z601 – 2018, Scale Reduction Devices. This standard requires a minimum of 70 per cent scale reduction to achieve certification. To date, no companies have been certified.

Chlorine and chloramines in municipal water quickly reduce the life of softener resin. Adding carbon pretreatment will extend the life of your customer’s softener resin.

The most effective filter media for removing chlorine is granular activated carbon (GAC) and for removing chloramines is catalytic carbon. Both media are available in a variety of whole home solutions suitable for pre-softener treatment and offer all the benefits of chlorine- and chloramine-free water throughout the home.

In the next issue, we’ll take a closer look at filtration systems including carbon solutions and how to properly diagnose and choose the right water treatment system to give your customers optimal water throughout their homes.

HOW TO PROPERLY SIZE A RESIDENTIAL TANKLESS WATER HEATER

Choosing a new tankless water heater for a home, whether the application is totally new or a replacement, demands a strategic approach that will inevitably impact the owner’s day-to-day routine. The tankless unit selected must produce enough hot water for all of the household’s demands, so selecting the appropriately-sized model is imperative.

With tankless water heaters, water is heated on demand, removing the need for storage. If a unit is undersized, water will still warm to the temperature you set during installation; however, as heated water starts to run out, water flow will drop to uncomfortable levels to maintain that set temperature.

In other words, the household will continue to have hot water at the fixture, but lower water pressure creates a negative experience if multiple people live within the household. Only a few fixtures will be available at full flow if the water heater is too small to accommodate the simultaneous use of multiple fixtures. With an inappropriately sized tankless water heater, users will start to see their water pressure dwindle − water will appear to be dribbling out of the fixture.

On the other hand, oversizing a tankless system will not affect functionality. While an undersized unit cannot provide the appropriate amount of hot water if water usage is high, a slightly oversized unit is well equipped to handle it.

Of course, a larger unit will likely cost more, but household gas consumption will be the same as if the water heater had been properly sized. This is because with a tankless, gas consumption is based on hot-water demand, not model size. That is why it’s always best to size properly or even slightly oversize to maintain maximum efficiency of the water heater installed.

With tankless water heaters, size refers to the flow rate of the hot water produced measured in gallons per minute (GPM). This rate will vary, up or down, depending on the temperature difference between the cold water coming into the heater and the hot water it generates. This difference is known as the temperature rise, or Delta T.

Determining the correctly sized tankless water heater for a home can be completed with three easy steps.

1Determine the Maximum Temperature Rise

The first step in sizing a tankless water heater is to determine the maximum temperature rise, which usually occurs during the coldest days of the year in a locale. Begin with the tankless set temperature. Health Canada recommends 120°F as the safest, yet comfortable temperature with an anti-scald mixing valve on the water heater.

Next, subtract the wintertime cold-water temperature from this set temperature. Winter groundwater temperature is equal to the mean air temperature above the land surface during the winter months. This temperature varies based on location.

To determine the most accurate wintertime cold water temperature for your locale, you will need to reference a guide to the average winter water temperatures. The assumption is 35°F to 40°F for most of Canada in the winter, with the lower West Coast of Canada potentially up to 45°F. Wintertime cold water temperature can also vary within a province.

For our purposes, let’s use the Toronto area, where the coldest groundwater temperature is 42°F.

THESE THREE EASY STEPS MAXIMIZE THE FULL POTENTIAL OF THE UNIT

Sizing and selecting a residential tankless water heater demands a strategic approach.

Following Health Canada’s recommendation of a set temperature of 120°F and subtracting the wintertime cold water temperature of 42°F calculates as a difference of 78°F. That is your maximum temperature rise.

Determine the Combined Flow Rate

Determining the peak hot-water demand of a particular home is the second step. To do so, you must identify the maximum number of hot water fixtures that will consistently be used simultaneously in the home such as first thing in the morning, when everyone is getting ready for work and school. Keep in mind that product flow rates − again in gpm − vary among manufacturers. These rates can be found on the fixtures themselves or on the product packaging. Or you can contact manufacturers directly. Note: Average flow rates found online tend to be expressed on the higher side to add a buffer for proper sizing. The following are typical flow rates for common hot-water appliances:

Dishwasher: 2.0 gpm

Kitchen faucet: 1.5 gpm

Lavatory faucet: 1.0 gpm

Shower: 2.0 gpm

Washing machine: 2.0 gpm

Next, add together the individual flow rates of all the household hot-water outlets that would be used simultaneously and you have your targeted, peak-usage flow rate: the number of gallons per minute needed at any given time, including the coldest day of winter when the temperature rise from the cold ground water to the hot-water outlet will be at its highest (in Figure 1 the winter groundwater temperature is 45°F), and multiple outlets are in use. A relatively small peak usage might be two showers and a washing machine, whose flow rates would add up to six gpm. A larger household might have a peak usage of four showers and, say, a dishwasher, the sum of whose flow rates are 10 gpm.

2 MANUFACTURER’S SIZING CHART

1 COMBINED FLOW RATE

Select the Tankless Water Heater

The final sizing step is selecting the proper tankless model or models to meet the peak demand. Larger households may require more than one tankless unit.

To make the selection, use a manufacturer’s sizing chart. These charts are typically available online, and are also often found in manufacturer product catalogues. Listed on the left-hand column of Figure 2 is the maximum temperature rise during the coldest period of the year, ranging from 30°F to 100°F.

• Listed across the top are the different model numbers available, commercial and residential, divided into condensing and non-condensing.

To determine peak hot water demand identify the maximum number of fixtures that will consistently be used simultaneously.

• The numbers in the columns beneath the model names are their flow rates for the different temperature rises. The colder the climate, the larger the temperature rise, the lower the flow rate. Next, find the temperature rise that corresponds to your locale. Then read across to find the flow rates equal to or greater than the combined flow rates of all the hot-water outlets that would be used simultaneously by the household.

• For our small-peak usage example, the options would include any model with a flow rate at or above six gpm, for which there are several options.

• For the large peak usage example, we would need to select a pair of tankless models with a combined flow rate at or above 10 gpm.

In either case, those are the tankless water heater models that would meet the combined demand of the simultaneously operating hot-water outlets.

Once again, if you select a tankless solution with a flow rate lower than the peak-usage target, the resulting water pressure is bound to be unsatisfactory (if not downright unpleasant for the unlucky individual taking a shower).

Finding and installing a model whose flow rate will encompass the highest combined demand on even the coldest days should result in a very happy customer.

The final sizing step is selecting the proper tankless model or models to meet the peak demand.

An option to resolve insufficient airflow

Whole home comfort requires getting conditioned air to where it is supposed to be

Do you ever feel frustrated by customers’ HVAC system’s inability to provide conditioned air to some of the rooms furthest away from the furnace?

You are not alone. Insufficient airflow is one of the most common heating and cooling complaints made by clients and they look to us to fix the issue.

Many people are at a loss as to why their HVAC system is able to serve some rooms much better than others. While there are plenty of reasons for this, one explanation is a small or weak fan that is incapable of moving the right amount of air through the ductwork and out of the vents.

In cases such as these, an air duct booster fan may be a solution.

How do they work?

Inline and register are the two main types of booster fans.

Insufficient airflow is one of the most common heating and cooling complaints made by clients.

As the name implies, an air duct booster fan is basically a fan that can be attached to the ductwork in an HVAC system. Designed to increase the airflow to the more distant parts of a home, a booster fan will typically be installed in long sections of ductwork and then hooked up to an electricity supply.

Inline fans are built to be installed inside the ductwork itself. Because they can shift large volumes of conditioned air, inline fans are often used in larger properties with extensive networks of ducts. These fans look somewhat like a regular section of ductwork. They are designed to replace a section of regular ductwork, so it is essential to choose one with the same dimensions as the existing ducts. Once installed, these fans are cheap to run and do not use much in the way of electricity.

Instead of being installed as part of the ductwork itself, register booster fans are designed to replace the registers in rooms that are receiving low airflow. Register fans are cheaper and cost less to install. They also plug directly into the wall. Some of the better models have thermostats, variable speed options, and remote-control operation.

While register booster fans cost significantly less than the inline solution, the amount that is saved on a single unit will likely be offset when you have to install multiple fans in each room in which you need to increase air flow.

Inline fans are designed to replace a section of regular ductwork.

What is an air duct booster fan?

Register fans are less expensive than inline booster fans and cost less to install.

What are the advantages of duct booster fans?

Booster fans may not solve the airflow problems in an HVAC system on their own, but they can help increase air circulation in a number of ways.

Boosting older ductwork

Modern HVAC systems have revolutionized how we heat and cool our homes. However, merely installing a powerful new furnace or air conditioning system may not yield the results that it should if the customer lives in a home that has ductwork from another era.

Old ductwork did not use today’s airflow technology in its design and often fails to pull air through the system to supply all rooms of the house, evenly leaving warm or cold spots in the home.

In cases where you have old ductwork, it may be more cost-effective to install a duct booster or set of register fans to help move the air through the ductwork better.

Extra power for complex ductwork layout

Larger properties with many rooms or several floors often require complex ductwork systems to connect the whole indoor environment up to the HVAC system. A more extensive system of ductwork will mean that warm or cool air will be lost due to low airflow to rooms further away from

Booster fans can be an effective way of moving air past the many bends and divisions that usually feature in larger networks of ductwork to improve heating and

Inline booster fans can be placed strategically near sections with registers to help pull more of the air past them so more of it reaches underserviced rooms and

Put off costly repairs

In some cases, booster fans can be used to effectively put a bandaid on an HVAC unit that is not working that well anyway. Some customers want booster fans or register fans installed to increase airflow to avoid paying money for repairs or a new HVAC unit that is capable of pushing through higher volumes of conditioned air.

When a duct booster fan will not work

There are several cases in which installing a duct booster fan will not provide the necessary solution. If the ductwork is old and has cracks and holes through which air is escaping, it is unlikely that simply pulling through more air is going to make much difference to the volume of airflow in hard-to-reach rooms of the home.

Similarly, if the furnace or AC unit is old and worn out so that it no longer produces sufficient conditioned air, increasing the airflow with a fan will have no effect.

Before installing a duct booster fan, you should first check that the other parts of the system are working correctly. Airflow problems may be caused by damaged or leaky ductwork, clogged filters, or a system component that needs replacing.

The Penalty Box

How to discipline an employee

Almost everyone can agree on the basic rules of working: we must turn up on time, we will follow instructions, and we should try to successfully complete the tasks as assigned to the best of our abilities. But that last point can be a bit of sticky one for employers who haven’t done their homework. What actually constitutes a task properly completed and what should you do when someone falls short of your definition of success?

No matter what the size of your team, at some point in your career as a manager, you’re going to come across that problem person you’ll need to correct. Whether it’s attendance, performance, or attitude, sooner or later you’ll have to have the tough conversation. When it’s impacting your bottom line, it’s time to discipline with a view to either correct and improve the behaviour, or to start building a strong enough case to fire them.

Ideally, you’re reading this well in advance of having any issues. We’ll start with some preventive measures you can put into place now to keep your people on the right track. If you’re already in a position to want to wring some necks, skip to the next section, and come back when things are back under control.

Prevention

When an employee’s performance is less than stellar, it’s tempting to assume they are solely to blame. Cooler heads will realize this isn’t always the case. Before reading someone the riot act, pause and think about why the behaviour is occurring.

The actions you are witnessing could have roots in a company deficiency, or an individual (or likely, both).

Is it possible there’s something missing in your hiring or training practices that led to this employee lacking a critical skill set?

Have you set clear, achievable markers for what constitutes acceptable performance and communicated them? What about the supervisor? Is that person good at setting expectations and providing constructive feedback in real time? Could there be something personal happening you’re unaware of that may require some accommodation?

Lack of training can be corrected with coaching, poor fit can be fixed by reassigning workers, but the best (and least expensive) method to prevent issues later is to ensure you’ve hired the right people, and told them clearly what you expect them to do. Every prospective hire should be given a realistic job preview during the interview process. Each employee should also have a written job description and know how their performance will be measured. An Employee Handbook or Company

Code of Conduct that lays out basic standards and expectations will do more to prevent maleficence than any threats or shouting matches ever could!

Once you have an Employee Handbook in place, ensure you include a line in your offer letters telling prospective employees they must abide by the policies and procedures you’ve set out in it, and that you reserve the right to revise those policies from time to time. It is also a good idea to communicate those policies and procedures to all employees once a year. Have copies posted online or available in common areas. The more opportunities employees have to review the information, the less likely they are able to deny knowledge of it.

Discussion

So, you’ve written down the rules, you’ve hired the right people, and you’ve told them what you want them to do and how to do it and yet you’re still having an issue with an employee. Now what? There is no “one size fits all” approach to holding a discipline conversation. You’ll need to decide on a case-by-case basis whether an incident requires an informal chat or a formal meeting and a write up.

Very generally speaking, if this is an isolated incident without a legal, reputational or financial impact on your company, from a normally strong performer you have a vested interest in retaining, the best choice may in fact be to let this one go. Note the date, time, and basic details of the incident in the employee’s file and then move on. If things worsen, you can refer to your notes and start a performance improvement plan, but if this was truly a one-off, you’ve avoided upsetting a key employee in a challenging labour market.

For issues such as poor attendance or performance, a multi-stage, progressive discipline procedure is appropriate. Verbal and written warnings with escalating consequences can underscore the importance of improvement and provide you with protection against wrongful dismissal charges, should the path lead to termination. Communicating this in advance of any issues is key.

In the case of much more serious issues, such as incidents of theft, violence or any criminal actions, a measured conversation about progressive improvement obviously won’t cut it. In these most egregious (but typically, rare) circumstances, you can move immediately to termination, generally without notice or severance. A note for unionized employers − collective agreements lay out grievance procedures, but they only apply when

an article of the collective agreement has (allegedly) been violated. This is seldom the case in a disciplinary matter; employers with collective agreements still retain the basic right of managing their workforce, which includes the ability to discipline employees for a wide variety of infractions. Again, having an unambiguous written policy that is clearly communicated and enforced across all employees will leave less room for arguments and put you in a much safer position should you need to discipline one of your employees.

Regardless of the type of actual conversation, best practice is to have a third (preferably neutral) party on hand and to keep diligent notes. When having uncomfortable conversations, it’s best to do some advanced planning. Book a time and place where you will not be interrupted. Present the employee with the facts, including dates, times and particulars of the infraction(s), and allow them time to respond. They may become defensive or they may not wish to engage but be persistent and ensure they understand what the issue is and why their behaviour is unacceptable. Along with the input of the impacted employee, develop a plan to address the issue. Is there further training required? Do they need wellness supports or accommodations? In the case of a formal written warning, have the employee sign off on the letter and provide them with a copy, to avoid later misunderstandings as to what’s been agreed upon.

DOCUMENTATION

Document any and all conversations in the employee’s file and set a time frame for a follow up, which can be anywhere from one week to one month, depending on the circumstances. Make a note in your calendar of the follow up date and follow through. Review the progress made, or repeat the warning and let them know the consequences for failing to improve.

Failing to address employee issues will have immediate and longterm effects. Remember that when you leave negative behaviours unchecked, you are in fact endorsing those same behaviours as acceptable.

And remember, it’s both harder on you and unfair on the employee to say they’re doing a bad job when you haven’t fully defined what constitutes a good job. If you set clear expectations, and enforce them equally across all workers and situations, you’ll have a much easier time coaching those employees falling short, or terminating those employees who aren’t meeting your needs.

How to adjust marketing tactics during a recession

It’s no secret that talk of a Canadian recession and the dramatic increase in the cost of living has been at full volume as of late. In fact, a lot of business owners are operating as though the country has already entered a recession or will do so within the next 12 months.

Because recessions have historically caused high unemployment rates (though it’s likely to be a different story on that front this time), business closures and bankruptcies, preparing for an economic downturn is the only way to ensure your business doesn’t get caught in the fallout. If you’re reading this, chances are good you provide a product or service that homeowners and business owners are hoping to either pay as little as possible for, or not need at all in an uncertain financial time. That is until it becomes urgent and then nobody wins.

That’s where strategic marketing decisions come into play. Here are ways you can adjust marketing efforts to lean into and get through a complex economic period.

Adjust your messaging

By

When belts tighten it’s not business as usual: a shift in approach is warranted.

Acknowledge the recession by reinforcing your value as a preventive service as much as a “there fast when you need us” emergency service. Promote the fact that routine maintenance can help people get ahead of breakdowns and repairs, which can be costly for the owners. Encourage upgrades to more efficient equipment to ultimately save on fuel costs. Show them the long-term savings potential.

Similarly, many contractors have learned the value of headlining with a loss leader reduced fee for a first call: it gets them to the site, where they can either provide a quick fix for a reasonable cost or, in many cases, be the first (and possibly the only) contractor in line to price out equipment replacement and lock in a monthly plan.

Highlight financing and membership options

Recessions mean we’re more prudent with cash flow predictability. Owners feel more secure knowing their monthly expenses. Promoting a monthly membership-style program that folds in the costs for routine maintenance, emergency calls and most small parts and pieces can offer stability for customers that may nudge them in your favour.

Financing is a complicated solution these days given interest rates and the tiny margins that most contractors operate within, but a competitive financing program can also be a vital asset in a tight economy. This is generally the easiest way to support people who are in dire need of your services and to promote your services to those who just want the financing as an option.

Replace some hard costs with human costs

Advertising can be expensive and while I’m not advocating for a wholesale reduction in consumer-targeted advertising in traditional or digital outlets, these avenues can be supplemented with good old elbow-grease marketing. Have employees drop low-cost postcards at homes in neighbourhoods where they’re working, or pick up the phone to connect with former or existing customers to check in and suggest a pre-emptive service call.

Digital marketing on Google and social media, among many other options, can be pricey. Learn more about how these systems work and commit to frequent analysis (read: at least once per day). If you adjust your investment based on reviewing metrics and recalibrating the campaign even slightly, it can make the money you spend work with a lot more precision.

Upping community presence by contributing staff hours and company resources to important, high-profile causes such as a charity home build or food hamper delivery service keeps the business name out there without major cost. As an additional benefit it reminds people that you care about the communities you work in.

Launch a creative and fun promotion

The most tangible recession tactics include sales promotions that show consumers how working with you puts cash back in their pockets. Some historically successful promotions include “we’ll buy your old unit from you” when the consumer upgrades, “buy one get one” deals on specific services or goods, or cashback opportunities – “it pays to buy from us.”

There will always be a spend – no matter what the industry, service, or product, money will be spent. Promotions are a great way to advertise how spending with your company is the most mutually beneficial.

Ramp up your content

Blogs, social media content, email newsletters, short homemade videos, call-in radio shows (if you can swing it), and even old-school flyers at home shows should offer your expert advice on how to keep energy costs low to keep the budget in check. Sharing simple tips reinforces your expertise, and commitment to serving the community.

And finally ... don’t retreat

Most importantly, in a time when businesses are watching their expenses closely, it’s tempting to slash marketing budgets or staff capacity, and as a result, lose market presence. I’ve seen this time and again and those businesses don’t come out the other end as strong. Marketing remains the mainstay to sustaining and growing pretty much any business. Just because it’s easier to trim costs there than in some of the locked-in areas such as vehicle leases or insurance, doesn’t mean you should do it. Some companies have successfully ramped up their marketing during tough times to fill the gap others are leaving, building their brands as calm, confident and reassuring during a rocky time.

Adjust your digital marketing investment based on reviewing metrics and recalibrating the campaign.
