Working Principle: This system relies on natural circulation, the water in vacuum tube will be hot after the coating layer absorbs solar energy. As we know, hot water is lighter and cold water is heavier, so hot water will flows into tank and cold water will flow to vacuum tube bottom, this circulation continues because of different water temperature between the tank and vacuum tube. At last, the water temperature in tank and vacuum tube will be the same, and circulation will stop. Then you can get hot water after several hours
