How to use the Heat Pump vs. Resistance Heat Calculator
The Formula
Coefficient of Performance = heat delivered ÷ electrical input. Resistance heat = COP 1. A COP 3.5 heat pump uses ~1/3.5 the kWh for the same heat.
Practical Example
COP drops in extreme cold—use seasonal average from your heat pump specs or utility case studies.
