Excellent Thermal function and high working temperature: Even in winter times the rate of heat conduction of solar water heater can be over 55%
All-weather all year round use: No matter in the north or south, even the temperature be minus 40 degree the product could work normally, it avoids the possibility of burst of the freezing tubes which have water running in.
Reliability: For no water runs in the tube, no incrustation or burst of tubes, nor freezing tubes in cold weather, it can work well at? Minus 40 degree.
Super heat pipe combines excellent heat absorbability, rapid heat transfer and long life.

Vacuum tube is made of 3.3 high boron silicon glass tube that owns high transparency, low inflation and low emissivity etc. The low inflation of vacuum tubes guarantee no burst in extremely high or low temperature, and the capability of resistance to35mm hailstone.

Pressurized capability: 0.6 MPa.

Eight Advantages of sonne Super heat pipe:
Rapid heat conduction, the speed of heat conduction is 1000 times than the performance of copper.
High heat collecting efficiency, at least 20% upgrade than common solar system.
No water runs in tube, no incrustation, no burst of tubes even at minus40 C.
The medium of super heat conducting has low working pressure, it wont burst when the pipe reaches 300 C in the summer.
Can be connected with city tap water, the pressurized system work automatically(Pressure: 0.6 MPa).
Whole system can work normally when single pipe is broken, and no water bursts out.
In the north, they can be used normally when it is sunny in the winter.
Special silica gel for sealing up is not easy to aging, release automatically when high temperature or high pressure in heat pipes.
