Air to water heat pumps make use of the latent energy from outside air by converting it into heat that can be used with a typical wet heating and hot water system.
The heat pumps use the constant energy from the air with a refrigerant circuit to boot temperatures for the provision of heating or hot water.
The refrigerant meets the outdoor air in the evaporator (heat exchanger) of the outdoor unit. The air is drawn through by a fan on top of the heat pump. The liquid refrigerant absorbs free energy from the air and evaporates in the process, being led into the compressor. Here, the pressure is increased and the vapour
