How a domestic hot water heat pump works?

Hot water heat pumps are often confused with solar hot water and in some ways this confusion is justified. Solar hot water heaters rely on incidental sunshine to affect the heating while hot water heat pumps take heat from the ambient air and use this energy source to heat the water. The hot water heat pump does not need sunshine to operate nor does it need large roof panels, in fact for commercial applications the units look like traditional hot water heaters. Day or night, rain, hail or shine, they produce hot water but with efficiencies so that traditional hot water heating bills can be slashed by 50-75%.

The integrated hot water heat pump is a patented system whereby heat from the ambient air is absorbed by an environmentally friendly refrigerant in the evaporator. This refrigerant gas is then compressed which causes the gas’s temperature to be raised. This hot gas is passed through tubes wrapped around the outside of the water tank. This heat is then transferred to the water inside the tank.

Once the heat from the compressed gas has been transferred to the water in the tank, the gas becomes a liquid again, and then passes through an expansion device and back to the evaporator. The cycle is then repeated until the water in the storage tank reaches 55°C~60°C.
