 Working pinciple:

Solar vacuum tube was evacuated into the tank, the coating inside of tube can absorb more than 92% 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. 50mm 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.
