<1> Best heating efficiency: Heat pipe as heat exchanger, good absorbent coating and best combination between them!

<2> Wide applicable range: As the heat pipe has less heat capacity, it works very quick even under cloudy days and collect heat effectively.

It can work normally even -30 degrees. As no water in the vacuum tube, it can effectively prevent low heat efficiency due to frost cracking or scaling!
<3> Each individual tube can work independently, and the whole system can still work if any one of them get damaged. The lifespan of our heat pipe is more than 15years.
<4> The connection between the heat pipe and vacuum tube is good and vacuum tube can be replaced if broken!
