Working Principle of unpressurized solar water heaters:
The basic non-pressure system SWH is a passive system, which relies on a natural principle-thermosiphon. There is water in the evacuated tubes and free to flow into tanks. When the water in the tubes is heated by sun's rays firstly, this makes water in the tubes lighter. Therefore, the cold water in the tank move downwards and hotter water move upside into the tank. It is an open circuit since the air vent and the overflow pipe is open to the air.
Material of solar water heater:
1.Vacuum tube:1.6mm thickness double glass, high borosilicate 3.3 with Cu-AL-SS coating.58mm×1800mm
2.Water tank:0.5mm inner tank(SS304),0.4mm outer tank(color steel),50-60mm high pressure polyurethane thermal insulating.
3.Bracket:1.5mm thickness galvanized steel
4.Optional Accessories:assistant tank(4L), electric heater(110V/220V)
Features of unpressurized solar water heater:
1.Sunseason water heater equipped with excellent solar-thermal conversion and low heat loss vacuum tubes.
2.Freeze-proofing, anti-scale and anti-corrosion
3.Together with auxiliary electric heater, it can provide hot water even in the low-radiance day.
4.Easy installation and can be combined with the building or architecture perfectly.
5.Long using life, 5 years warranty.
