Working principle

         The selective coating on the inner cover of the evacuated tubes converts solar energy into heat energy and water in evacuated tubes aborbs the heat.According to temperature rises along with density drops,and weight goes down,hot water will go up to exchange with cold water in tank. In this way,the temperature of the water in tank goes
