Air Source Heat Pumps are one of the most efficient heating systems today where approximately 75% of the energy needed for heating comes from ambient air in the environment.
Coefficient of Performance (COP) measures the efficiency of a heating device. The more efficient the device is, the higher the COP will be. Air Source Heat Pumps have a COP of 3.00 to 4.00 or above. This means that 3kWh to 4kWh of heating energy is produced for every 1kWh of electricity used to power the Heat Pump.
