Pre heated solar hot water heater
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
3. Working principle is more advanced than thermosyphon solar water
4. Economical type in compact pressure systems.
5. Simple structure and easy installation.
6. Stable operation and quality.
