Air source heat pumps use the refrigeration process to transfer low grade energy from the air outside into high grade energy used for heating and domestic hot water. Even at temperatures as low as -20C, an air source heat pump can supply significantly more energy than it uses – and with no local C02 emissions, it helps reduce impact on the environment.

Heat pumps are measured by their coefficient of performance (COP). The COP for air source heat pumps is very similar to that for ground source heat pumps at approximately 2-3. With a COP for instance of 3, 3 units of heat are produced for every 1 unit of electricity consumed. (The two free units of heating were extracted from the outside air). Even with ambient air temperatures of -10 to -15 degrees Celsius, an air source heat pump can extract useful heat (i.e. > 1 unit of heat generated per unit of electricity consumed).
