Detailed Product Description

  Non-pressurized compact solar water heater is a kind of solar water heating system that solar collector and storage water tank are connected together, water tank on the top and collector panel on the bottom. It relies on the natural circulation of waters between the collector and the water tank. As water in the vacuum tubes is heated, it rises naturally into the tank, while cool water in the tank flows down to the bottom of the vacuum tubes, causing circulation throughout the system. It moves household water or a heat-transfer fluid through the system without pumps. It is a simple and safe solution to get heat power from the sun.
