Solar water heater can provide hot water for bathing, washing, heating space and connect solar collector for swimming pool.

Details of non-pressure solar hot water:
1, Inner tank: SUS304-2B stainless steel
2, Outer tank; Galvanized steel plate with 0.4mm thickness
3, frame material: Galvanized steel plate with 1.5mm thickness.
4, Vacuum tube dimensions: 47mm*1500mm/58mm*1800mm/58mm*2100mm
5, Insolation layer: imported polyurethane foam for superior heat preservation
6, Capacity: 160-240liter
7, Heat preservation: 72hours
8, Hail resistance: 25mm

Working principle:
1, The high quality vacuum tubes absorb the solar ultravilet ray; Then heat the cold water in the vacuum tube.
2, The hot water rise in the top of the water tank, and the cold water sink to bottom then heat by solar collector. So the whole system is always circulating continuously.
3, The electromagnetism or ball valve can perform the water supply automatically, the water in the tank is not sufficient, the electromagnetism valve will open its valve, the tap water flow in the water tank, if the water is full, it will close the valve automatically.
