Sun Storm specialize in solar water heaer and its relative components.
working principles
Solar vacuum tube was evacuated into the tank,the coating inside of tube can absorb more than 93% heat energy from sunshine.The cold water in water tank flows into the tube and become hot,because of different density between cold and hot water,there will be a natural circulation in the tube,hot water will float back to tank.55-60mm thickness heat insulation layer by polyurethane between inner tank and outer tank can keep the temperature of hot water for about 2 days without any sunshine,consumer can enjoy comfortable bathe anytime.
