Is a Heat Pump Right for You?
A heat pump is a device that can heat a building by transferring thermal energy from the outside using the refrigeration cycle. Despite the name heat pump, a heat pump can both heat and cool your home using a reversing valve which pumps heat out of your house during hot summer months, and pumping heat into your house in the winter.
What HSPF Means For Your Home:
Heating Seasonal Performance Factor (HSPF) is a heating efficiency rating specific to heat pumps. The higher the rating, the more efficient the heat pump.
Heat pumps with a rating of at least 8.2 HSPF are awarded the ENERGY STAR label by the US EPA. However, for a heat pump to have the ENERGY STAR label, it must also have a Seasonal Energy Efficiency Ratio (SEER) rating of 12 or greater.
