The air source heat pump hot water unit is an energy-saving and environment-friendly hot water supply device that can replace the boiler without resource constraints. It uses green pollution-free cold coal to absorb the heat in the air. Through the work of the compressor, it can produce domestic hot water up to 95 degrees, with the C.O.P value of more than 3.0 throughout the year. The air source heat pump hot water unit is applicable to indoor swimming pools, hotels, villas, hair salons, foot baths, factories, farms and other places that need hot water and heat sources. The air source heat pump hot water unit can be used for refrigeration at the same time in the heating process, and can also be installed in places where the cooling capacity is required but the requirements are not high. The annual average energy efficiency ratio of the heat pump system can reach 3-4, which is higher than the heating efficiency of any kind of fossil fuel combustion. Therefore, the heat pump system is the most energy-saving hot water unit. Even compared with the solar hot water system, the operating cost of the heat pump hot water system will be lower. If the local solar energy utilization days are only within 2/3 of the year (the solar energy utilization is greatly affected by day and night, weather, rain and snow, and seasons. Except for Tibet, Xinjiang, and Qinghai, the average effective solar energy utilization days in general areas throughout the year are less than 2/3 of the year, that is, less than 250 days), and the auxiliary heating is also electric heating, then the power consumption of the heat pump water heater unit can be equal to that of the solar water heating system, Or it can save more electricity than the solar system.

As we all know, we used coal fired boilers, oil fired boilers, gas fired boilers, and electric water heaters before, but if compared, heat pump water heaters are the ones with the highest thermal efficiency. The efficiency of oil fired boiler is 65% - 75%, the efficiency of electric water heater is 70% - 80%, and the efficiency of heat pump is 300% - 500%. As the heat pump water heater has a thermal efficiency of 300% - 500%, the cost of preparing hot water is extremely low, and electricity will be saved naturally.
