Overview
The Coefficient of Performance (COP) measures the ratio of useful heating or cooling provided to the work required. Unlike efficiency, COP can be greater than 1.
💡
Pro Tips
Heating Mode: COP = Heat Output / Work Input.
Cooling Mode: COP = Heat Removed / Work Input.
Carnot COP is the theoretical maximum efficiency for a given temperature difference.

Fun Facts
"Typical residential heat pumps have a COP between 3 and 4."
"A COP of 3 means 3 units of heat are moved for every 1 unit of electricity used."
"As the temperature difference increases, the COP decreases significantly."
