FEATURE: a perfect combination of the vacuum tube and the heat pipe
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 lowering 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.
