The advantages of solar water heaters of fresh water: 

 Water pressure, without the addition of booster pumps, hot water pressure from the cold water pressure, hot and cold pressure match, surging heat, water temperature regulation freely. 

 Use RHES-reverse heat transfer technology, the thermal storage tank heat medium heating coil heat exchanger in the cold water, this process, without the aid of pumps and other external forces, and timely access to hot water without any pollution, water quality, pressure and similar municipal cold water.

 20 seconds fast heat transfer technology, in the municipal water supply situation in cold water, cold water flow through the stainless steel corrugated tube heat exchanger 20 seconds quickly into hot water, and temperature and the heat medium temperature difference of 2 to 5 °, non-pathogenic bacteria group fresh water quality, drinking.

 No artificial recharge, not string the water, not bombing, worry and effort. 

 Closed system can match with any conventional heat source (electricity, gas). 

 Vacuum tube, the tank does not scale, to facilitate future maintenance. 

 The appearance of new, different. 

 The solar water tank was a square round, installed on the roof relative to the circular water tank can be good a good integration with the building.
