How to Calculate Heat Pump COP
COP measures how efficiently a heat pump converts electricity into heat.
Formula
COP = Heat Output (BTU/hr) / (Electrical Input (W) * 3.412)
A COP of 3 means the heat pump produces 3 units of heat for every 1 unit of electricity. This is possible because heat pumps move existing heat rather than generating it.
Typical COP Values
Example Calculation
A heat pump producing 36,000 BTU/hr using 3,000W of electricity, running 2,000 hours/year at $0.15/kWh.
- 01COP: 36,000 / (3,000 * 3.412) = 36,000 / 10,236 = 3.52
- 02Annual electricity: 3,000 * 2,000 / 1,000 = 6,000 kWh
- 03Heat pump cost: 6,000 * $0.15 = $900
- 04Gas furnace equivalent: 36,000 * 2,000 / 100,000 * $1.50 / 0.92 = $1,174
