more HVAC definitions. HSPF is an abbreviation for Heating Seasonal Performance Factor. It is the most commonly used measure of the heating efficiency of heat pumps.(The cooling efficiency of a heat pump is measured by its SEER .). Technically speaking, the HSPF is a heat pump's estimated seasonal heating output in BTUs divided by the amount of energy that it consumes in watt-hours. heat pump with a high HSPF is more efficient than a heat pump with a low HSPF. New heat pumps manufactured after 2005 are required to have an HSPF of at least 7.7. The most efficient heat pumps have an HSPF of 10.
