solar thermal collectors

THE PRINCIPLE
1) Solar absorption: Solar radiation is absorbed by the solar tubes and converted into heat.
2) Solar heat transfer: Heat pipes conduct the heat from within the solar tube up to the header pipe.
3) Solar energy storage: Water is circulatedthrough the header, via intermittent pump cycling. Each time the water circulates through the header, the temperatures is raised by 5-10oC. Throughout the day, the water in the tank is gradually heated.

THE FEATURES
1. The water is heated by the heat pipe rapidly.
2. There is no water in the vacuum tube, so the tube will not break in the winter.
3. It can be combined with the architecture perfectly.
4. It can be combined with existing pipeline.
5. It will be affected by the local water quality, it doesn't suit hard water.
6. It can be still operate in the event of occasional tube breakages.
7. The perfect solar collector for domestic solar water heater systems;
8. Ideal for commercial solar water heating applications.
9. Storage do not need be installed above the collector.
10. Low maintenance effort.
11. Easy plug-in installation of single or multiple units, Collectors could be installed using parallel and/or series connections.
12. It can be installed both on pitched roof and flat roof.
