9. The emission rate is 0.05 to 0.075 (80 ± 5)
10. Vacuum tightness is P ≤ 5.0 x 0.0001Pa
11. Idle sunning property parameters is Y = 220 to 260/kW
12. The average heat loss coefficient is Ult = 0.6 TO 0.7W (. )
13. It means the temperature in the water tank is range from 50 to 95
14. Type: 16, 18, 20, 24, 26, 28 and 30 tubes

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.
