Heat Pump Water Heaters

Heat Pump Water Heaters
How a heat pump works
The heat pump system contains a fan that forces air through an evaporator (1). The evaporator contains a liquid refrigerant. This refrigerant evaporates and extracts heat from the ambient air.
The refrigerant then passes through the condenser (3), which in this case is wrapped around the water tank. The hot refrigerant loses its heat which goes into the DHW.
The now warm gaseous refrigerant is then compressed (2) by the compressor which is driven by an electric motor. As it goes through the compressor the pressure and temperature rises. The refrigerant turns back into a liquid which is now hot.
If the heat pump that is built into the unit alone cannot keep up with the hot water demand then an electric backup element with 1.7 kW loading will automatically activate.
The now cooler refrigerant then passes through an expansion valve (4), where it goes back into a gaseous state and the process begins anew.
