How do water heat pumps work?

Water Heat Pumps work using a process called the refrigeration cycle. The refrigeration cycle is a series of events that occur in a sealed system of interconnected evaporator coils, compressors, condenser coils, and expansion valves. A Best Water Heat Pumps (WHP) is a mechanical device that uses refrigeration principles to heat or cool water. In warm weather, a WHP can be used to cool water by absorbing heat from the surrounding air and transferring it to the water. The evaporator coils are filled with a refrigerant?a substance that readily absorbs and transfers heat. The compressor pressurizes the refrigerant, which causes it to evaporate and absorb heat from the surrounding air.
