high end vacuum tube 

1) Reliable, efficient, twin-glass evacuated tubes. 

2) Red copper(TU1) heat pipes, The water is heated by the heat pipe rapidly.

3) There is no water in the vacuum tube,so the tube will not break in the winter. 

4) It can be combined with the architecture perfectly, standard frame suitable for pitched roof or flat roof . 

5) It can be combined with existing pipeline.

6) Significant advantages over flat plate.

7) Can be used all year round in the cold climate.

8) Improves the environment and save your fuel cost. 

 Feature:

   1. Higher heating efficiency:

Heat transferring can be started quickly even under cloudy day. It can work normally even -30 below degree. As no water in the vacuum tube, it can effectively prevent the lowing of heating efficiency due to frost cracking or scaling

   2. Each individual tube can work independently, and the whole machine can still work if individual tube is damaged. The service life of the heat pipe can be longer than 15 years

   3. The unique connection between the heat pipe and the vacuum tube can ensure both sealing and replace of the damaged glass vacuum tube.
