WebHSPF, or Heating Seasonal Performance Factor, measures how efficiently a heat pump can heat your home during the cold weather months. The Department of Energy (DOE) has … Heating seasonal performance factor (HSPF) is a term used in the heating and cooling industry. HSPF is specifically used to measure the efficiency of air source heat pumps. HSPF is defined as the ratio of heat output (measured in BTUs) over the heating season to electricity used (measured in watt-hours). It therefore has units of BTU/watt-hr. The higher the HSPF rating of a unit, the more energy efficient it is. An electrical resistance heat…
WebNov 1, 2024 · In 2010, China revised GB/T 17758-2010 [7], and the standard established the seasonal performance evaluation system of the SEER/CSPF, HSPF, and APF approaches for air-cooled unitary air conditioners based on the climate characteristics of China through related research. WebSep 2, 2024 · For example, if a split system heat pump is rated with 14 SEER2 and 10 HSPF2, it will be modeled with a SEER and HSPF of: Cooling efficiency = 14 SEER2 = 14/0.95 SEER = 14.74 SEER. Heating efficiency = 10 HSPF2 = 10/0.85 HSPF = 11.76 HSPF. 2. Reference Homes with Federal Minimum Efficiencies.
