Main Que: What does HSPF stand for?

Answer: HSPF stands for Heat Seasonal Performance Factor, which measures a heat pump’s heating efficiency. The higher the HSPF, the more efficient the heat pump. More technically speaking, the HSPF represents the total heating output of a heat pump during the normal heating season, as compared to the total electricity consumed during the same period.
