Detailed Product Description
1) solar collector is designed with pressure up to 0.6Mpa.
2) Easy to use, also convenient to install
3) Can be put in the courtyard, on the roof or balcony
4) Inlet water hole connects to the tap water, and the outlet hole connects to the tap water, and the outlet hole produces pressure hot water directly 5)Efficiency: The advantage of solar tubes is that insulate the inner tube from heat loss. This means that once heat is absorbed, it is transferred to the water in the manifold, and not lost to the outside environment. This is the key difference between solar tubes and flat plate solar collectors: the insulative properties. Combined with heat transfer efficiency of the heat pipe, the collector can deliver excellent heat output all year round.
6)Aesthetics: solar collector is designed to be low profile, sitting closed to the surface of the roof. Tubes are black and so blend in nicely with most roof colors.
7) Heat pipe has its special principle and function, and no water in the pipe. If one of the pipe is broken, the heat collector still could be used normally. Therefore, this kind of products has gradually accepted by consumers. However, every coin has two sides. The product also has its disadvantages. 

1) Use patent heat pipes, it is sure that no water goes into the tube and there are no incrustation, no bursting. Moreover, water can go upward at anytime.
2) Use solar collector technology, it is sure to be anti-freezing in winter, and it could also work in the bad weather with high efficiency.
3) Use the electric heating water tank specially for solar water heater.
4) Double energy: You could use hot water at any time in a day because solar water heater also has an electrical heating system for auxiliary heating.
5) Automatically intelligent control and management all day.
