Product Description
Working Principle:

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.
