System Working Pricinple:

Description: this system is water and collector integrated solar water
system, it is easy for mounting, and efficiency is high.

Specification:

1. Inner tank material: SUS304-2B food grade stainless steel 0.31mm

2. Outer tank material: stainless steel sheet 201, thickness 0.31mm,

3. Bracket:1.2mm SS 202 stainless steel sheet

4. Vacuum tube: 58mm diameter, 1800mm length,coated by AL-N-AL

5. Insulation layer: 50-65mm polyurethane foam

6. Hail resistance:25mm 7.Heat preservation:72hours

Working Principle:

This type use all-glasses evacuated tubes as the solar collector for absorbing sun energy and transferring

it into heat energy.

As the different densities of hot water and cold water, the hot water flows automatically upwards while the cold water flows down.

The water flowing cycle is created in the tube. And the water in the storage tank is heated from this natural circulation.

The hot water pressure of this non-pressure system is from the gravity, so it should be installed on the roof or at least 3-4 meters higher than hot water tap.

Or you can install a booster pump to get stronger outlet hot water.
