2. Product Model

 

3.  Low pressure solar water heater working principle

-Solar riadiation is absorbed by the selective coating of solar vacuum tube, it changes solar energy into heat energy; 

-Cold water flows in vacuum tube and absorbs the heat energy, as time goes by, it becomes hotter and hotter;

-As water temperature rises up, water density decreases, so hot water floats up and cold water floats in to replace void.

-Through this circulation, the cold water in the water tank will be gradually heated.

4.  Features

-Simple structure and easy installation 

-Automatic water feeding with assistant tank, if not, we should controll the water feeding by hand             

-Withstands water pressure no more than 0.1MPa             

-Electric heater can be used as back up in rainy days

 

5.  Advantages of our product: 

Inner tank: Non-welding technology of tank cover:

Decrease the welding damage to original material, increase system lifespan, no worry about leakage

Outer tank: A plastic film covering on the plate before packing. Prevent scratching and keep it with a nice appearence.

Insulation Layer: Germany-imported polyurethane integrated foam-forming with twice slaking treatment. Preserves hot water constantly as long as 70~80 hours.

Supporting Bracket: Electrostatic spray & Automotive paint galvanized steel plate

Good weight bearing and wind resistance(140 km/hr), super mechanical performance and corrosion resistance ensures a long life to ocean coast, easy installation, universal bracket suitable for either flat or slope roof installation.
