What is the coefficient of performance (COP)? If a heat pump rated for 5 kW is on for 30 min and delivers 10 kW of heat in that time. What is the COP? Answer: The coefficient of performance (COP) is a measure of efficiency for heat pumps and is the ratio of heat energy delivered to energy supplied to the heat pump. The energy supplied in 30 min is (5 kW)(0.5 h) = 2.5 kWh The energy delivered = (10 kW)(0.5 h) = 5kWh The COP-5 kWh/2.5 kWh = 2 x What is the coefficient of performance (COP)?
