Heat Pump COP Calculator
COP from Energy Data
Calculate COP from heating output and power input
SEER/HSPF to COP
Convert between efficiency ratings
Formula
COP = Heating Output (W) / Electrical Input (W) | SEER = COP x 3.412
Frequently Asked Questions
What is COP?
COP is the ratio of useful heating or cooling provided to electrical energy consumed. A COP of 3 means 3 units of heat for every 1 unit of electricity.
What is a good COP?
Modern heat pumps achieve COP of 3-5 in mild conditions. COP decreases as outdoor temperature drops. Above 2.5 is generally good for heating.
