When the air temperature outside drops below 3ºC, an air source heat pump’s efficiency levels can reduce but your heat pump will still continue to operate to fulfil your heating and hot water requirements. The Aerona³ heat pumps are designed to work in air temperatures as low as -20ºC so they can operate in cold weather below freezing. You may notice that during cold weather, as the heat pump is not working at its optimal efficiencies, your energy consumption may increase during colder spells.
The Aerona³ heat pump incorporates clever features which enable it to continue operating, even when the outside temperatures are low. To learn more about the unit's defrost cycle and electric heating element, please watch the video below.
