Unpressurized solar collector
1. Applicable to solar hot water supply/ swimming pool heating/ house heating.
2. Operates automatically, telecommuting controlling.
3. The design allows for versatile architectonic integration.
1. It is the system that can place most vacuum tube in unit area.
2. Adopt natural circulation, Without electricity, Reliable operation, Low failure rate, Almost free maintenance.
3. Relatively speaking, the cost of the collector is less than others.
4. Due to place the vacuum tubes in the horizontal direction, the central collector pipe is the channel in the up-and-down direction, Provided the possibility for empty the system.
So it can realize anti-freezing and provide lots of water. When the system stop working, still have lots of hot water in vacuum tube, using the empty technology can enjoy more water.
5. The distance between the bottom of tank and up end of the collector should more than 0.5 m.
6. The up circulation pipe should lay in a third of tank.
