WebAvg COP = Heat transferred / electrical energy supplied = (HSPF * 1055.056 J/BTU) / (3600 J/watt-hour) = 0.29307111 HSPF. For instance, a system which delivers an HSPF of 7.7 will transfer 2.25 times as much heat as electricity consumed over a season. [5] WebFeb 2, 2015 · A heat pump may have a COP of 1.5 to 4.0, meaning it operates at 1.5 to four times the efficiency of electric-resistance heat. A heat pump operates at this efficiency because it uses a compressor and refrigerant to move heat from one space to another, instead of generating heat.
