1. This kind of solar hot water heater relies on the natural circulation of water between the collector and the tank.
2. Water in the evacuated tubes is heated and rises naturally into the tank, while cold water in the tank flows down to the bottom of the evacuated tubes, causing circulation throughout the solar heating system.
