If you’re shopping for a new comfort system, it’s likely that you’ve heard about the efficient, cost-effective and sustainable features of heat pumps. These systems have been sought after in warm climates for many years. But because they use heat from the outdoor air and transfer it inside, conventional wisdom indicates that installing them in cold climates is not worth the effort. This could have you wondering if a heat pump is the right choice for your home in the Northern U.S. or Canada.
Before going more in-depth, rest assured that modern, cold-weather heat pumps are suitable for northern climates. Over the past decade, the adoption of heat pump technology has surged in Northern European countries like Norway and Sweden. With ordinary January temperatures sitting around 20 degrees F, homeowners in these areas obviously need powerful heating options. Those who have installed cold-climate heat pumps have been delighted to discover that they meet their needs perfectly.
Heat pump technology was once unsuitable for cooler climates. As the temperature dipped below freezing, these systems were unfortunately unable to collect enough heat to efficiently warm a house. But this is no longer accurate. Here are the special features used in cold-climate heat pumps that allow them to perform efficiently at temperatures below 0 degrees F.
Heat pump efficiency is measured by its heating seasonal performance factor (HSPF), which demonstrates the total heating output over the heating season divided by the energy consumed for that period. The higher the HSPF, the better the efficiency.
Beginning in 2023, the national minimum efficiency rating for heat pumps will be 8.8 HSPF. The majority of cold-climate heat pumps offer ratings of 10 HSPF or higher, allowing them to operate at up to 400% efficiency in moderate weather. In other words, they move four times more energy than they use in the process.
Performance falls 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 max out at about 98% efficiency.
In terms of actual savings, results may vary. The biggest savers are usually people who heat with delivered fuels including propane and oil, as well as those who use electric furnaces or electric baseboard heaters.
Nevertheless, heating with natural gas still tends to be less expensive than running a heat pump. The cost difference will depend on how tough the winter is, the utility rates in your area, whether your heat pump was installed correctly and whether you use solar panels to offset electricity costs.
If you’re thinking of transitioning from a traditional furnace, boiler or electric heater to a cold-climate heat pump, consider these other factors:
