Features:1) The tubes and supports are adjustable. The power bearing is average and can assure the vacuum tubes to use for a long time2) Whole glass vacuum tubes adopt super hard borax and silica glass3) It resists 25mm hail and the using life can last 15 years4) Temperature when exposed to sun without water: 250oC, 2.5 hours to boiling point if using single tube5) If you use electrical appliances to aid heating and to switch off the power supple before bathing6) Please test the water temperature before using, in order to avoid scalding
Working Principle
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 different density between cold and hot water, there will be a natural circulation in the tube, and hot water will float back to tank. 50 mm 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.
