An air-to-water heat pump is a unit that transfers energy from the surrounding air to heating and prepares hot domestic water. An air-to-water heat pump works similarly to any refrigerator, using a gas pressure change cycle. The outdoor unit fan drives outdoor air through the outdoor unit radiator – the heat exchanger. This radiator contains very low-temperature refrigerant which, when "warmed" by the outdoor air, changes its state of aggregation to gaseous.
The compressor then increases the pressure of the gas and accordingly a high temperature is achieved. The heated gas is transferred to the indoor unit, where it transfers the carried heat to the water through the heat exchanger. The refrigerant then flows back to the outdoor unit and the cycle is repeated.
An air-to-water heat pump will provide fully automatic heating in your apartment, home, office or shop. The unit can be connected to a water heating system – radiators, underfloor heating, warm air blowers. This unit can be connected as the sole heating unit or as a supplementary heating unit.
