1 Working principle of Non-pressurized Vacuum Tube Solar System

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

absorb 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 3 days without

any sunshine. Consumer can enjoy comfortable bathe anytime.

2 Features of Non-pressure Evacuated Tube Solar/Hot Water Heater

1. Imported Stainless Steel.

2. Reliable and efficient.

3. CE Approved.

4. Stable solar conversion during the day.

5. Easy installation.

6. Ideal for many solar water heating applications.

7. Can be used for heating water, room and floor.

8. Simple structure and working principle.

9. 5 years' warranty for the whole system.

10. Environmental.

3 Advantages of Non-pressured Solar Hot Water Heater

Comparing with non-pressure flat panel solar water heater:

1. Higher efficiency collector, much lower heat loss;

2. Super anti-freezing performance for cold weather;

3. Convenience in parts carrying and installation;

4. Much lower maintenance cost for collector;

Comparing with heat pipe solar water heater

1. More cost effective;

2. Lower maintenance cost;
