Twenty-two years ago, my wife and I built a house in the north end of Guelph, ON. At the time we had been married for almost five years, had one child with another soon to arrive and we wanted to…
Buildings such as apartments and condominiums are home to families with different comfort preferences or attitudes on energy use. Similarly, many commercial buildings are divided into spaces where tenants have different temperature requirements or usage schedules. In some buildings, the…
Water is the “life-blood” of hydronic systems. Its chemical characteristics can make the difference between a system that lasts for decades, versus one that develops expensive corrosion issues within months of commissioning. We discussed the advantages of establishing and maintaining…
In October 2018 Natural Resources Canada (NRCan) published new proposed energy efficiency regulations for heating equipment in the Canada Gazette Part 1. These proposed regulations are part of Amendment 15 to the Energy Efficiency Act and introduce new or increased…
A building’s hydronic HVAC system is rarely just the sum of its parts. The system is comprised of chillers, boilers, pumps, variable frequency drives (VFDs), air handling units (AHUs) and valves that create a loop through which water is circulated…
Hydronic heating has long been known for providing superior cold weather comfort. Even so, the question that often comes from potential clients who are already convinced about of the benefits of hydronic heating, is: “What do I do about cooling?”…
The Ampex Insulated PEX Panel is designed for a cost-effective installation of hydronic radiant in-floor heating systems. The panel is a combination of EPS molded to a high impact polystyrene film resulting in a stronger, resilient interlocking panel. It is…
Most hydronic heating systems that have renewable energy heat sources, such as solar thermal collectors, an air-to-water or geothermal heat pump, or a biomass boiler, also have an auxiliary boiler. Many of these systems also have one or more thermal…
Every year the impending winter season prompts Canadians to prepare for winter. Safely storing summer gear, closing the pool or cottage, putting snow tires on our vehicles are things we know we have do before old man winter arrives with…
Baxi S.p.A is extending its operations in Canada. The Italian company announced plans to transfer all North American business and support to its North American factory operations. Baxi North America, headquartered in Utica, NY, will now be exclusively distributed through…
Radiant heating systems can now be installed in Alberta without adhering to former insulation requirements set forth in section 9.36 of the National Model Energy Code for Buildings. The provincial building administrator and provincial plumbing/gas administrator have developed a Standata…
Controls play an integral role in ensuring today’s hydronic radiant systems operate as energy efficiently as possible while still providing ultimate comfort to the consumer. Every system should, at the very least, be employed using outdoor weather compensating controllers or…
When it comes to thermal storage tanks, there are many shapes, sizes and pressure ratings available, ranging from tanks that resemble (or are) domestic water heaters to larger ASME-certified pressure vessels. In most hydronic thermal storage applications, it is desirable…
Viega has rolled out its trades education program, a supplement to school curriculum on the design, installation and function of plumbing and hydronic systems. The Viega Trades Education Network (VTEN) program offers complete tooling packages, access to LoopCAD radiant heating…
Several manufacturers have introduced new balancing valve technologies into the market. Familiarity with these new valves, as well as traditional balancing valves, will assist you in selecting the correct one for specific hydronic and plumbing system applications. MANUAL BALANCING VALVES…
The Canadian Institute of Plumbing and Heating Exposition (CIPHEX) West will return to Calgary, AB, on November 7 and 8, 2018. The trade show features more than 250 global exhibitors. It will focus on plumbing, hydronics, HVAC/R and water treatment.…
One of the biggest thieves of efficiency in boiler operations is the accumulation of soot and/or scale on heat exchanger surfaces. It does not take long for soot to start causing significant loss of energy efficiency. In a matter of…
Over time the hydronic industry has changed the approach to system piping designs and temperature control as equipment efficiency and technology has evolved. In the late 1960s and early 1970s out-door air reset was utilized. This allowed for better temperature…
It is not uncommon for contractors, and sometimes consumers, to call me to complain about the performance of a hydronic system. Many of these times, if it is not system settings related, it is because the consumer is expecting different…
There is currently a lot of attention being devoted to reducing greenhouse gas (GHG) emissions from buildings. One of the primary methods that governments are using to meet their goals is to tighten up building codes to require super-insulated and…
Many hydronic heating professionals like to promote that the modern boilers they install are capable of operating with thermal efficiencies in the range of 95 +/- per cent. Professionals who install geothermal heat pumps often boast that their equipment is…
Sound complaints are the number one indoor environmental quality problem in buildings today, surpassing thermal comfort, indoor air quality (IAQ) and lighting quality in the hierarchy of occupant discomfort. Objections can be anything from chatter in offices, to the neighbour’s…
The Plastics Pipe Institute, Inc. (PPI) is hosting a webinar on hydronic snow and ice melting systems, intended for mechanical engineers, designers, contractors, building owners, facility managers and architects. Held in conjunction with its education partner RedVector, the first webinar…
