Haier HP M1 Electric Water Heater (Boilers), Vertical, 3kW

Water heaters with built-in air heat pumps - a new type of water heating equipment that provides efficient heat accumulation and exchange - mainly consist of a compressor, expansion valve, filter, evaporator, condenser, and fan. The heat pump is powered by electricity, and the compressor absorbs low temperature and low pressure gas refrigerant from the evaporator. In this process, the gas is compressed, resulting in high temperature and high pressure gas, which is then delivered to the condenser and transfers its heat energy to the water, thereby increasing the water temperature. The condensed refrigerant flows through the heat pump after throttling and pressure reduction in the expansion valve, where it absorbs heat from the surrounding air using the fan installed in the evaporator, and then is sucked in for compression in the compressor, where it is recycled to obtain hot water.
