Non-Pressurized Solar Water Heater with Assistant Tank

Solar heater with asistant tank relies on the natural circulation of water between the collector and the tank. As water in the vacuum tubes is heated it rises naturally into the tank, while cooler water in the tank flows down to the bottom of the vacuum tubes, causing circulation throughout the system. The assistant tank plays as the automatic feeder
