Non-pressured solar water heater
Water Tank:
1, SUS304-2B Inner tank.
2, Polyurethane foam insulation
3, Stainless or aluminum support
4, Trivalent element evacuated tube.
5, Electromagnetism or ball valve(optional)
6, Electrical boost heater (optional)

Working principle:
1, The high quality vacuum tubed absorb the solar autraviolet 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 circilating 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

We can make the models for customer's order. So if you ask for special size please let us know.
We could also provide the pressurized tank, the circulating pump, the controller and the expansion tank for favorable price.
