It is a sample and safe solution to get heat powerfrom the sun. The principle of the system Compact solar water heater relies on density of the water , cold waterdown, hot water up . To circulate through the collector and watertank. When water in the collector is heated up, it becomes lighter andnaturally rises into the water tank. Meanwhile, cooler water in the tank flowsdown to the collectors
