Solar  thermal water heater

Principle: Compact Non-pressure Solar Water Heater relies on desity of the water, cold water down, hot water up, a cosmical physics, to circulat water through the collector and the tank. When water in the collectors is heated up, it becomes lighter and naturally rises into tank. Meanwhile, cooler water in the tank flows down to the collectors.
