Air to Water Heat Pumps

Air to water heat pumps use outside air that is heated by the sun, meaning that there are no requirements for bore holes or coils in the ground, thus reducing installation time and costs. Air to Water Heat Pumps are suitable for new builds or existing dwellings where digging up the garden is not an option.

The air to water heat pumps work by converting the energy of the outside air into heat, creating a comfortable temperature inside the home and supplying energy for the hot water. The efficiency for an air to water heat pump is measured by coefficient of performance (COP). An air to water heat pump can convert 1kW of electricity into 4kW of usable heat giving a COP of four. This means that you get 3kW of free energy from the surrounding air.

Air to Water Heat Pumps should cover the heating and hot water requirements all year round. Alternatively, an air to water heat pump with an output smaller than the heat demand can be docked with new or existing heating systems incorporating an alternative heat source. The heat pump provides efficient heating for most of the heating season with supplementary energy from the alternative heat source, only being required in extreme winter periods.
