The low-temperature heat energy in the air is converted into high-temperature heat energy through the compressor. Based on the same amount of hot water production, compared with electric heater water heaters, it can save electricity to the greatest extent. The use cost is only 1/4 of that of electric water heaters. Compared with gas water heaters, there is no need to consume any gas fuel, and the cost of use is only 1/3 of that of gas water heaters.
