This model works with high pressure, so it can be connected with city water directly. With the heat pipe in the vacuum tube, therefore no water in the tube, each tube can work alone, so the solar collector can work even one tube is broken.

1. Highly efficient absorber of high performance with daily average efficiency over 50%
2. Start up quickly, the water is heated rapidly by heat pipe which will transfer the heat energy into the tank
3. Withstand pressure of 6 bar, more comfortable to use
4. Simple structure, easy to assembly and install
5. Can be used all year even in the cold climate area
6. Long service life, can be used over 15 years
