After learning that the Canadian government will offer $2 billion to homeowners who install heat pumps next year, CBC News Sudbury consulted experts to discuss the technology’s effectiveness in extreme cold. Heat pumps are evaluated based on their SEER rating, or Seasonal Energy Efficiency Ratio, as explained by Anthony Davis, the operations manager at Greater Sudbury Plumbing, Heating, and A/C. The higher the SEER rating, the more efficient the heat pump is considered to be.
Davis mentioned that the most efficient heat pumps currently available in Canada can manage temperatures around -35 degrees Celsius. These models are often referred to as “cold climate heat pumps,” according to Steve Filioglou, the general manager at Tombari HVAC in Sault Ste. Marie. However, both Filioglou and Davis recommend combining a heat pump with another heating source, such as natural gas, propane, or electric heat, for extremely cold days when temperatures drop to -40 degrees Celsius and below.
Davis expressed optimism that heat pumps could eventually become the primary heat source for homes as the technology continues to advance significantly each year. Martin Luymes, the vice president of government and stakeholder relations for the Heating, Refrigeration and Air Conditioning Institute of Canada, cautioned consumers to choose contractors wisely. Some contractors may lack confidence in newer heat pump technology’s ability to withstand cold temperatures due to their limited understanding, leading them to recommend traditional heating solutions like natural gas furnaces or boilers.
Despite the suggestion to pair heat pumps with additional heating systems, Filioglou and Davis agreed that installing a heat pump is cost-effective due to its energy efficiency, resulting in significant cost savings. Filioglou highlighted the appeal of heat pumps for rural residents who may be relying on expensive oil or propane heating systems, emphasizing the economic benefits and flexibility these systems offer. Both experts anticipate an increase in demand for heat pump installations following the government’s rebate announcement.
In summary, heat pumps are proving to be a viable and efficient heating solution, especially in colder regions like Northern Ontario, with the potential to deliver substantial savings and improved comfort for homeowners.
