What is a heat pump pool heater?

By general definition, a heat pump pool heater is a closed cycle reverse cooling system using an evaporator, a compressor, a condenser and a pressure control regulator device to heat water instead of cooling air. The heat pump uses a refrigeration cycle exactly like your refrigerator or air conditioner. It moves and absorbs heat from ambient air, amplifying the process through compression action of the compressor, and transfers it to the water in the heat exchanger.
