Air Source Heat Pumps

The outside ambient air contains an inexhaustible amount of latent heat. Even in temperatures as low as -20°C there is still heat available for an air source heat pump to absorb.

Air source heat pumps use a fan to absorb this heat from the outside air. There are two types of air source heat pumps; an air-to-air source heat pump, and an air-to-water source heat pump.

Air-to-Air Source Heat Pump
An air to air source heat pump is an all-in-one heating and cooling system. It can be used to deliver both warm and cool air into the property. This means it can be used as a heater during the winter and as an air cooling system in the summer.

Air to air source heat pumps are best suited for open plan areas such as apartments, holiday homes and workshops. For larger properties air to air source heat pumps are only suitable as a supplementary heat source, or for parts of the building such as a conservatory.

Air-to-Water Source Heat Pump
An air to water source heat pump is designed to meet and supply all the demands for heat and hot water of the property all year round. This means they can be totally self sufficient and there is no other need for any other kind of supplementary heat source.

Air to water source heat pumps can be fitted as part of a heating system consisting of radiators. However, we recommend radiators are upsized by between 20-30%. Better still, heat pumps are best combined with underfloor heating as they use water at low temperatures which will optimise the heating system’s coefficient performance rating.
