The basic non-pressure solar water heater is a passive system. Working principle depends on Gravity. There is water in evacuated tubes and free to flow into tanks. When the water in 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, then keeps the movement re-cycling. It is an open circuit since the air vent and the overflow pipe is open to the air.
Advantages for non-pressure solar water heater:
1, it is the most economic solar water heater with high efficiency.
2, Simple structure, easy plug-in installation, can be installed both on flat and inclined roof.
3, Can be used with an electric heater to provide hot water if there is not enough sunshine.
4, Superior heat preservation ensured by high-pressure integral foaming with thickness 50mm.
5, Can be operated completely automatic if connect with intelligent controller.
6, Stable and reliable performance, well wind resistance.
7, Meet the mankind healthy bath standard: the material of inner tank is SS304-2B stainless steel plate.
8. The silicon sealing ring has a long life against the erosion and it does not harm to health.
