Web2 sep. 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. WebHSPF is calculated by dividing the total seasonal BTU output by the amount of energy consumed in an identical time period. Heat pumps are mandated to have a minimum rating of 7.7 HSPF. Since each watt of electricity yields 3.4 BTUs, a heat pump with a 7.7 HSPF rating will deliver 2.25 times the heat relative to the power it uses.

Web15 sep. 2024 · The higher the HSPF, the more efficient the heat pump. In technical term, HSPF represents the total heating output of a heat pump (including supplementary electric heat) during the normal heating season (in Btu) as compared to the total electricity consumed (in watt-hours) during the same period. WebHSPF in 1980, the model has undergone a continual series ... sion of new releases, leading up to the most recent Re-lease 12 in 2001 (and Release 12.2 in 2005). Since 1981, ... WebHere is how we can calculate both HSPF and HSPF2 rating for the same heat pump: HSPF Rating = 10,000 BTU / 1,000W = 10 HSPF. HSPF2 Rating = 8,500 BTU / 1,000W = 8.5 HSPF2.

WebHSPF is calculated by dividing the total heat output during a heating season by the total electricity consumed. Basically, it tells you how much heat you get (in BTUs) per kilowatt-hour of electricity. For example, a heat pump rated 10 HSPF will produce 10 BTU’s of heat for every kilowatt-hour of electricity.

Web15 sep. 2011 · 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 … WebHSPF measures the energy efficiency of a heat pump while it’s heating, while SEER measures its energy efficiency while cooling. Since heat pumps deliver heating and cooling, they will have an HSPF rating and a SEER (Seasonal Energy Efficiency Ratio) rating.
