Working Principle:

There is water in the vacuum tubes and free to flow into tanks. When the water in the tubes is heated by the 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 top of the tank. It is an open circuit since the air vent and the overflow pipe is open to the air.
