The supply tank was heated as a priority by a freon-line switching device to increase the temperature recovery speed. A dual-tank prototype with 100- liter capacity was built and tested. The experimental results show that the time for temperature recovery of the supply tank from 42°C to 54°C reaches 10-20 minutes and COP reaches 2.0-3.0 during various seasons. The prototype tests show that an energy saving around 50%-70% as compared to the electrical water heater can be obtained. The hot water discharge efficiency of the heat pump is 0.912.
