Description Of   Pre-heating Solar Water Heater

Working Principle:

The main working principle adopts heat exchanging technology.

1. Cold water inside the vacuum tube heated by sunshine, and then hot water go up to tank, cold water in tank flow into collector, cold and hot water form a natural circulation in solar water heater, the whole tank water will be hot water gradually.

2. Then hot water inside water tank transfer heat to water inside copper coil, people use hot water directly from copper coil.


1. Hot water inside copper coil is fresh without secondary pollution; it can be used as portable water 

2. Copper coil inside tank can take pressure and connect tap water directly.

3. Working principle is more advanced than thermosyphon solar water heater.

4. Economical type in compact pressure systems.

5. Simple structure and easy installation.

6. Stable operation and quality.

Technical specification:

1. Outer tank material: SUS304-2B /316L stainless steel or powder coated color steel 

2. Inner tank material: 0.5mm thick SUS304/316L food grade stainless steel 

3. High purity copper for the heat exchanger coil

4. Frame material: 1.2mm thickness stainless steel or galvanized steel

5. Insulation material: 55mm thickness polyurethane

6. Reliable, efficient, twin-glass Al-SS-CU solar vacuum tubes

7. Designed to accept mains pressure cold water

8. Copper coil heat exchanger can be used as part of a closed or open loop system, providing heating to a main hot water tank

9. Easy plug-in installation
