FAQ: AIRSTAGE™ VRF Systems What is the heating seasonal performance factor (HSPF)?

  • 0006

Answer

HSPF is the total heating output of a heat pump, including auxiliary electric heat, necessary to achieve the heating requirements for a building over an average heating season.

HSPF is calculated by dividing the total amount of heat provided during the colder months by the total energy consumed during the same period.
