If you’re shopping for a new home comfort system, odds are you’ve heard about the efficient, cost-effective and eco-friendly features of heat pumps. These systems have been sought after in warm climates for decades. But considering they absorb heat from the outdoor air and transfer it inside, conventional wisdom indicates that installing them in cold climates is not worth the effort. This might have you questioning if a heat pump is the right choice for your home in the Northern U.S. or Canada.
Before going into more detail, rest assured that modern, cold-weather heat pumps are appropriate for northern climates. In the last decade, the adoption of heat pump technology has soared in Northern European countries such as Norway and Sweden. With frequent January temperatures hovering around 20 degrees F, homeowners in these regions obviously depend on powerful heating options. Those who have installed cold-climate heat pumps have found that they fulfill their needs perfectly.
Heat pump technology was once too weak for temperate climates. As the temperature dipped below freezing, these systems were simply unable to extract enough heat to effectively warm a house. But this is no longer accurate. Here are the advanced features designed for cold-climate heat pumps that permit them to work efficiently at temperatures below 0 degrees F.
Heat pump efficiency is determined by its heating seasonal performance factor (HSPF), which illustrates the total heating output throughout the heating season divided by the energy consumed for that period. The higher the HSPF, the better the efficiency.
Beginning in 2023, the nationwide minimum efficiency rating for heat pumps will be 8.8 HSPF. Lots of cold-climate heat pumps come with ratings of 10 HSPF or higher, helping them to operate at up to 400% efficiency in moderate weather. In other words, they move four times more energy than they consume in the process.
Performance drops as the temperature drops, but numerous models are still around 100% efficient in sub-freezing conditions. Compare this to brand-new, high-efficiency furnaces, which top out at about 98% efficiency.
In terms of actual savings, results might vary. The biggest savers are likely to be people who heat with delivered fuels such as propane and oil, as well as those who use electric furnaces or electric baseboard heaters.
That being said, heating with natural gas still is generally less expensive than installing a heat pump. The cost gap depends on how tough the winter is, the utility prices in your area, whether your system was installed correctly and whether you have solar panels to offset electricity costs.
If you’re thinking of switching from a traditional furnace, boiler or electric heater to a cold-climate heat pump, consider these additional factors:
