Non-Pressure Series:
The non-pressurized solar water heater is a kind of solar water heating system the solar collector and storage water tank are connected together, the water tank on the top and the collector panel on the bottom. It relies on the natural circulation of waters between the collector and the water tank. As the water in the vacuum tubes is heated, it rises naturally into the tank, while cool water in the tank flows down to the bottom of the vacuum tubes, causing circulation throughout the system. It is a simple and safe solution to get heat power from the sun.
