1. Kelin Heat Pump is the green device which introduces the renewable solar energy in the air to water.So it is the most efficiency and environmental protection solution to heat the water for swimming pool and  house use.

2.The heat pump works by driving the refrigerant around the refrigeration circuit containing four elements, which including evaporator, compressor, water heat exchanger and expansion valve. The refrigerant changes from liquid to gas as heat is absorbed from the ambient air. Later in the cycle, the refrigerant condenses to liquid as heat is released to the water in the heat exchanger.

3.Kelin heat pump also can be used for cooling with the reversing valve that reverses the direction of the refrigerant and so the direction of the heat transfer.

4.Kelin heat pump transfers the solar energy in the air to the water. For each kilowatt of consumption recorded by your electricity meter, Kelin heat pump can transfer appropriate 4.5 to 4.7 kilowatt to the water. So It save nearly 80% of the energy .

5.The advanced titanium metal water heat exchanger, which resists the erosion from chlorine in the water, creates a longer lifespan.  In addition ,no pollution to the environment.

6. Without any touch betwween powerful electricity and water system,assuring safety.

7.Using the high-efficiency, low sound rotary or scroll compressor, lower  noise fan, high quality pump, creates a  quiet machine.
