According to conventional wisdom, heat pumps do not work in cold weather. This may have been true in the past, because they were typically shut down at temperatures around -8°C, due to a loss of capacity and to protect the compressors from damage. Heat pumps have evolved dramatically, and a new class of heat pumps has emerged, that are designed specifically for Cold Climates do not have this limitation. Cold Climate Heat Pumps operate effectively to temperatures as low as -30C and are available in Ductless Mini-Split systems, or Centrally Ducted Systems.
Mini-split heat pumps are ideal for heating and cooling homes that are heating with baseboard electric heaters or boiler systems. They are also ideal for spaces like add-on rooms and sunrooms where installing or extending ductwork isn’t possible.
Through the Canada Greener Homes Grant, installing a Cold Climate Heat Pump System may make you eligible for substantial money-saving with rebates, as high as $5000.00. Several Ductless Mini-Split Heat Pumps are classified as Cold Climate Heat Pumps, meaning the system has been tested and rated at temperatures typical of the Ottawa Valley. Many operate effectively as low as -30°C.
Mini-split systems are easy to install, using a compact indoor and outdoor unit connected through a small hole in your wall. One outdoor unit can support up to five indoor comfort zones, providing you with a customized whole-home heating or cooling solution.
With efficiencies of up to 24.5 SEER and 11.5 HSPF, mini-split systems deliver energy-efficient comfort and can save as much as 60% on your heating bill, as compared to electric heat.
Smooth inverter technology ensures quiet operation and keeps cooled or heated air flowing without the typical starts and stops of conventional systems, virtually eliminating temperature swings. Select mini-split heat pumps also offer outstanding cold-climate capabilities, operating in temperatures as low as -30°C.
