Working pinciple:

Solar vacuum tube was evacuated into the tank, the coating inside of tube can absorb more than *2% heat energy from sunshine. The cold water in water tank flows into the tube and become hot, because of diffierent density between cold and hot water, there will be a natual circulation in the tube, hot water will float back to tank. *0mm thickness heat insulation layer by polyurethane between inner and outer tank can keep the temperature of hot water for about 2 days without any sunshine, consumer can enjoy comfortable bathe anytime.
