Economical and heating for the home - GZ-NP

Vacuum tuber: High-efficient vacuum tube

High-Efficient heat-collection function: New generation o vacuum tubes, use molecular nanotechnology, greatly enhance heat-absorption by 20 percent, higher water temperatures.

Adopts the international advanced film-coating technology, solar thermal conversion rates extremely high, absorbing heat even if the cloud weather.

Vacuum tube strictly choose high-borosilicate glass 3.3 so that it has low coefficient of thermal expansion and higher intensity. Hail-resistance:25mm

Insulation: 55mm polyurethane keep heating do with aging the cell is small and uniform reasonable density excellent insulation

Frame: thicker galvanized steel , Anti-corrosive.and Anti-ultraviolet, installed in the slope and flat place freely.Strengthen hail-resistance. Best angle for the winter :45 degree.Through oxidation process.It increase wind resistance.,life is longer than common frame. Beautiful appearance.

Automatic operation: Digital controller shows water temperature and water lever,water loading automatically ,heating automatically ,controlling automatically.

How non-pressure solar water heater works
1. Non-pressure solar water heater of all glass evacuated tube collector integrated with storage tank, are ideal for use in houses and other applications where cheap, reliable hot water supply is required. They are simple, economic and practical.
2. As the specific gravities of hot water and cold water are different, cold water goes downward and hot water goes upward.
3. When cold water in evacuated tubes is heated, it becaomes lighter and goes to the water tank, while cold water in the tank goes down to the evacuated tubes
4. Through this circulation, the cold water in the water tank will be gradually heated.
