Working principle:
This system uses the thermo siphon principle. Solar vacuum tube is plugged into the bottom of water tank. This water is filled inside the solar vacuum tube transmit solar energy to heat energy. The temperature of water inside solar vacuum tube is rising. As the thermo siphon principle, the hot water rise up, and arrive in the water tank. The cold water inside the water tank go down the solar vacuum tube. So the system runs by this circulation way until the water become very hot. The highest temperature of water tank can be 95 degree Celsius. During this process, this system does not need any power, just under the sunshine. It is completely green and environmental..
