What is HSPF?

Heating seasonal performance factor or HSPF, is a simple measurement that tells consumers how effective and energy effiecient a heat pump can be at heating your home. The HSPF rating is calculated using the total amount of heating required over the course of a heating season (measured in BTU's), divided by the amount of energy a given heat pump consumes (measure in watt-hours). Meaning, a high HSPF rating will heat a home more efficiently then units with a lower HSPF rating. You can locate the HSPF rating on the energy guide label of any heat pump and use it to compare against other heat pumps when looking to purchase.

What is Considered a Good HSPF Rating?
To put HSPF ratings in perspective, the most efficient heat pumps sold have a rating between 8 and 10, 10 being the highest HSPF rating available. Because heat pumps are used to both cool and heat your home, you must consider both the HSPF and the SEER ratings together to decide what the best fit is. If energy saving equipment is a priroity to you, make sure to keep in mind that in order for a heat pump to qualify for the ENERGYSTAR® label, it must have an HSPF rating of at least 8 and a SEER rating of at least 14. Anything below these ratings are not guaranteed to be energy efficient.
