1. Our water heat pumps are one of the most advanced and high efficient equipments. Its working principle is extracting heat from air by the condenser and do heat exchange with water heat exchanger.
2. Our air heat pump machines are mainly used as showering and washing for institutions and service industries.
3. This product is mainly composed of compressor, system pipeline, orifice union, Four way valve assembly, heat exchanger(steamer), heat exchanger and shell.


1. High efficiency and energy saving: our water heat pumps cost less electricity and extract large amount of heat, so it has high heat efficient and low cost. Compared with traditional air heat pump, it can save 70% energy.
2. Environmentally friendly: it uses natural energy. There is no gas pollution, no smoke and dust emission and zero pollution for environment.
3. Reliability and safety: it can realize the insulation of water and electricity. There is no potential dangers like easily flammable, explosive, easily get electrical shock and easily poisonous.
4. The air heat pump auxiliary function can make hot water in 15℃~43℃ high efficiently without the infection of cloud, rain, snow and night.
5. Intelligent control. Micro computer control. easy operation and memory for cutting the electricity. The auxiliary function of electrical heating can prevent heating without water and over high water temperature.
6. Longevity and durability: the famous brand compressor has reliable performance and long life time.
7. Water heat pump has been approved of CE.
