About ‘Coefficient of Performance’ (COP)
COP is a ratio indicating the amount of energy required to run the heat pump, compared with the amount of energy being produced by the heat pump, to heat the water.
Standard testing, carried out to EN14511 establishes a benchmark COP at a particular ambient and circuit water temperature. This is air 7oC/water 35oC. For example, the Grant Aerona 13.0kW ASHP model produces a COP of 4.8, when tested to this level. This means for every kilowatt (kW) of energy used to run the Aerona, 4.8kW of energy is being given to the heating system in return.It is important to note that as the temperature outside gets colder, the COP of an air source heat pump reduces proportionately, due to there being less heat energy available within the air.
