Working Principle:
The main working principle adopts heat exchanging technology.
- 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.
- Then hot water inside water tank transfer heat to water inside copper coil, people use hot water directly from copper coil.
Specialty:
- Hot water inside copper coil is fresh without secondary pollution; it can be used as portable water
- Copper coil inside tank can take pressure and connect tap water directly.
- Working principle is more advanced than thermosyphon solar water heater.
- Economical type in compact pressure systems.
- Simple structure and easy installation.
- Stable operation and quality.
Technical specification:
- Outer tank material: SUS304-2B /316L stainless steel or powder coated color steel
- Inner tank material: 0.5mm thick SUS304/316L food grade stainless steel
- High purity copper for the heat exchanger coil
- Frame material: 1.2mm thickness stainless steel or galvanized steel
- Insulation material: 55mm thickness polyurethane
- Reliable, efficient, twin-glass Al-SS-CU solar vacuum tubes
- Designed to accept mains pressure cold water
- Copper coil heat exchanger can be used as part of a closed or open loop system, providing heating to a main hot water tank
- Easy plug-in installation
