air to water heater for central heating

Description

Air To Water Heat Pump Hot water heat pump is designed for offering hot water solution to your family. Characterized by more energy-saving and less cost, it has been more popular both at home and abroad. The heat pump is able to offer *5°C hot water, 3 times higher efficiency than that of gas boiler or electric heater, which could save a lot of cost for the user. An air source heat pump has three main parts: 1) An evaporator coil absorbs heat from the outside air and transfers it to a refrigerant; 2) The compressor pumps the refrigerant through the heat pump and compresses the gaseous refrigerant to the temperature needed for the heat distribution circuit; 3) The heat exchanger transfers the heat from the refrigerant to air or water. It is even possible for air source heat pumps to extract useful heat from air at temperatures as low as minus *5 ℃.
