Open Loop Circulation Vacuum Tubes Solar Collector For Solar Hot Water Heater
1. vacuum tube.
2. shield ring.
3. polyurethane foam thermal insulation.
5 the retaining bolt.
6 inner tank.
7 pipe sealing ring.
1. The food-grade SUS304 stainless steel tank, corrosion resistance, the service life is long.
2. The non-pressure running and can be used for natural circulation system, the collector absorb surface is big, installation is simple.

6 years international responsibility for U pipe solar collector and 15 years for vacuum tubes due to original quality problems.
Maintenance of the system is very easy and includes the following tasks:
Regular rain should keep the evacuated tubes clean, but if particularly dirty they may be washed with a soft cloth and warm, soapy water or glass cleaning solution. If the tubes are not easily and safely accessible, high pressure water spray is also effective.
During autumn, leaves may accumulate between or beneath the tubes. Please remove these leaves regularly to ensure optimal performance.
3. Broken tube
If a tube is broken it should be replaced as soon as possible to keep the system working. Any broken glass should be cleared away to prevent injury.
