Compact Unpressurized Vacuum Tube Solar Water Heater 

Specification of the Compact Unpressurized Vacuum Tube Solar Water Heater 

1.Type of vacuum tube: single target tubes / three target tubes

2. Inner tank: SUS304-2B/316L food grade stainless steel, thickness of 0.4mm

3. Outer tank:galvanized steel/color plate/stainless steel,  thickness of 0.4 mm

4. Heat insulating layer: import polyarethame foaming with high pressure and density,  thickness of 50 mm 

5. Frame material: galvanized steel or aluminum alloy ,  thickness of 1.5 mm

6. Heat preservation: 72-80 hours

7. Hail resistance: 25mm

8. Working temperature: 95 celsius degree

9. Cold resistance: -30celsius degree

Working principle: 

1.Solar vacuum tube was evacuated into the tank, the coating inside of tube can absorb more than 

92% heat energy from sunshine. 

2.The cold water in water tank flows into the tube and become hot, because of different density between 

cold and hot,  there will be a natural circulation in the tube. Hot water will float back to tank. 

3.The polyurethane heat insulation layer can keep the water warm about 2 days without any sunshine. 

4.Consumer can enjoy comfortable bathe anytime.
