Solar collector: Features:
The system could be mounted on the southern roof of the villa，on the courtyard lawn, or the southern slope of the construction. The hot water could be delivered to any floor without limitation. The system has adopted the forced circulation (automatic control) work module to control the temperature automatically and deliver water by pressurization. So it has solved the long time inconvenienc of manual operation. The system only needs small amount of investment, and it's easy to handle. Moreover, it's safe, convenient and energy saving, causing no pollution to the environment, so it's complemented as “Green Project”by the experts. 
 
The principle of the system：
1. The collector applies the fourth generation of solar collector---heat pipe vacuum collector to transfer the solar power to heat energy.
2. When the temperature of TC(the temperature of the collector) is higher than that of TR(the temperature of the water tank), the controlling device will start the circulation pump.
3. The circulation pump makes the working medium circulation in the system.
4. The heat is transferred from the heat collector to the water tank by the heat exchanger.
5. During the working process of the circulation pump, when the temperature difference is less than a set point, the circulating pump will stop.
6. When TR (the temperature of the water tank) reaches the highest of set point, the controlling device will close the circulation pump.
7. The electrical heating device will automatically make the temperature of the above part of water tank stay at the set point.
