How it work

Air to Water Heat Pump An air to water heat pump absorbs low temperature energy from air (usually outside air) raises it to a higher, more useful temperature using a refrigerant cycle and uses water to deliver the heat. A heat exchanger transfers the energy from the air to a refrigerant with a low boiling point which evaporates and circulates in a closed system. 

    The pressure of the refrigerant is raised by a compressor, which also raises the temperature to a useable level. The refrigerant then condensed in a second heat exchanger and releases heat to a water delivery system. The pressure of the refrigerant is then reduced by an expasion valve, its temperature falls, and it is ready to start the cycle again and absorb energy from the air.
