How would an air source heat pump be affected by cold weather?

When the air temperature outside drops below 3ºC, an air source heat pump’s efficiency levels can reduce but the heat pump will still continue to operate to fulfil the 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. Homeowners may notice that during cold weather, as the heat pump is not working at its optimal efficiencies, their 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.
