It is asample and safe solution to get heat power from the sun. The principle of the system Compact solar water heater relieson density of the water , cold water down, hot water up . To circulatethrough the collector and water tank. When water in the collector isheated up, it becomes lighter and naturally rises into the water tank.Meanwhile, cooler water in the tank flows down to the collectors
