Working principle & structure

-Solar radiation is absorbed by the selective coating of solar vacuum tube, it changes solar energy into heat energy; 

-Cold water in vacuum tube absorbs heat energy, as time goes by, it becomes hotter and hotter;

-As water temperature rises up, water density decreases, then hot water floats up and cold water floats in to replace void;

-Through this circulation, the cold water in the water tank will be gradually heated.
