How to use the Heat Pump Heating Cost Calculator
Use a measured or appropriate period-average COP for the temperatures and operation being modeled. COP is a dimensionless heat-output-to-electricity-input ratio.
The calculation
Worked example
1,000 kWh of useful heat at COP 3 and $0.20/kWh costs about $66.67, compared with $200 for ideal resistance heating.
Assumptions and limits
No seasonal efficiency is inferred from a single operating-point COP. Auxiliary heating, defrost, pumps, installation costs and changing weather are excluded unless reflected in the entered COP.
