split pressurized solar system ( open loop and close loop type)

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
