It is a sample and safesolution to get heat power from the sun. The principle of the system Compact solar water heater relies ondensity of the water , cold water down, hot water up . To circulate throughthe collector and water tank. When water in the collector is heated up,it becomes lighter and naturally rises into the water tank. Meanwhile, coolerwater in the tank flows down to the collectors
