 Working Principle   

Solar vacuum tubes are plug directly inside manifold tank, when cold water in evacuated tubes is heated with solar irradiation, as the specific gravities of hot water and cold water are different, hotter water goes upward to manifold tank and colder water goes downward to glass vacuum tubes. through this continuous circulation, the cold water in manifold tank will be gradually heated, in an active open-loop solar system, the hotter water in manifold will be pumped to hot water storage tank, and the same time circulate colder tank water to manifold collector for solar heating.
