What is Heat Pump Water Heater System Water heaters with heat pumps utilize electricity to move heat from one area to another, instead of producing the heat itself . The heat pump water heater that is a heat pump can be described as the best and most sophisticated water heating option that features reverse Carnot-cycle that utilizes refrigerant to capture the heat in the air. The heat is then transferred to water in the heater, warming the water. Working Process of Heat Pump Heater A heat pu mp operates in the same way as refrigerators, but instead of transferring heat from the refrigerator for a cooling, heat pumps inject heat directly into the water. The use of electricity is to push refrigerant throughout the system. The refrigerant is able to transfer heat absorbed from the air into the tank's water. Heat Pumps Comes in Many Different Sizes 200 Ltrs Heat Pump 300 Ltrs Heat Pump Solar Heat Pump 500 Ltrs Heat Pump The Heat pump is available in many size and all are
