preheated solar water heater - JNHX

JNHX compact pressurized solar water heater shows not only artistic appearance but more excellent efficient, reliable performance. It uses solar energy which could save your 20% cost on electricity and 60% consumption of gas. Jianeng brings you everyday a sunny life.
JNHX compact pressurized solar water heater takes advantage of the vacuum tubes which has the property of high absorptivity and low emissivity, and transfer swiftly the heat absorbed to the water by heat pipe inside the vacuum tubes. This kind of solar water heater can operate efficiently from summer to winter, and afraid not the frost cleft of the vacuum tubes.

Description:
1. With a SS304 2B food grad 1.2mm thickness tank water for hot water using.
2. Working pressure 6 bar
3. Vacuum tube and heat pipe vacuum tube can be optional
4. High efficient, stable performance, long lifet time service, easy installation, no need maintenance
Advantages:
1. Highly efficient absorber or high perfomance with daily average efficiency over 50%
2. Start up quickly, heat pipe transfer the heat energy into the storage tank in one direction
3. With standard pressure of 6 Bar, can be connected directly with tap water.
4. No water inside the evacuated tubes; The solar water heater can still in service even with several tubes broken
5. Highly efficient insulation with polyurethane foam
6. Simple structure., easy to assembly and install
7. Can be used all year round in the cold climate
Key Benefits
1. Uni-directional heat transmission
2. Can start from lower temperature
3. Faster transmission
4. Lower heat capacity
5. Low temperature resistance
6. Freeze-proofing
7. High frequency soldering inner tank
8. Operating pressure can be 1.2 atm.
9. No water in the vacuum tubes eradicates the incrustation scale, thus keeping them running in high efficiency,
10. No water in the vacuum tubes eradicates the leakage due to the aging of silica gel gasket or broken of the tubes,
11. No water in the vacuum tubes eradicate the frost cleft even in Jack Frost condition,
12. The whole system will still run even a single tube breaks,
13. Full automatic function,
14. Can realize pipeline evacuation
