- Page 9 Heat Pump Pool Heater 2 Product Introduction 2.1 Working Principle and Characteristics The pool heat pump heater is a new, efficient, energy-saving and environmentally friendly product. It uses the principle of heat pump to drive the compressor with electric energy. Through the thermal cycle, the heat absorbed in the air is transferred to the water-side heat exchanger for water supply (hot water), or the heat absorbed by the water-side heat exchanger (cold water) is released into the air through the thermal cycle.
