If you are looking to pump up your home's energy efficiency by installing a new heat pump system, you will want to pay close attention to 4 little letters: HSPF.
HSPF stands for heating seasonal performance factor and is a way to rate the heating efficiency of heat pumps. It is similar to the SEER ratings used to measure the cooling efficiency of heat pumps and air conditioners; in fact, the only real difference in the way the two ratings are calculated is that HSPF measures heating output instead of cooling output.
HSPF ratings tell you how many units of heat, measured in British thermal units, are produced for each watt-hour of electricity consumed. HSPF ratings for heat pumps typically range between 7 and 10. That is a large difference when you think about it: it means that a high-efficiency heat pump can produce about 1/3 more heat per watt-hour than a standard-efficiency unit. Choosing the higher HSPF rating, therefore, can save you considerably on your monthly heating bills.
Some heat pump systems use a different efficiency rating known as COP, or coefficient of performance. If you want to compare, you can convert HSPF to COP by multiplying the HSPF number by 0.293. An HSPF of 10, for instance, would be roughly equal to a COP of 2.93. COP is interesting because it tells you how much the heat pump multiplies the energy you put into it; a 2.93 COP means the system puts out 2.93 times as much energy as it consumes. In contrast, a furnace or boiler can never produce more heat energy than it consumes in fuel; it can never exceed a COP of 1.
