150L Copper Coil Pre Heated Solar Water Heater With Strong Aluminum
Alloy Material Bracket
1) Copper coil as twice heat exchanger makes a pressurized and
instant solar water heating system, tap water connects directly
with copper coil for continuing water supply.
2) Hot water output is instant continuous and not limited by water
3) An assistant tank can be quipped for storage tank water refill
and makes it a completely automatic running system
4) Instant water heating ensures more clean and convenient hot
Vacuum tube: Hail-resisting borosilicate glass with high-tech single-target
selective coating ensures an efficient solar collecting, tri-target
vacuum tube with its patent interference coating even makes the
efficiency improved by 12% and especially with a high temperature
Inner water tank: Food-grade stainless steel SUS304-2B as inner tank keeps the water
clean and drinkable, together with advanced welding techniques to
ensure a long lifespan ( more than 15 years).
Water tank shell: Stainless steel SUS304-2B/BA as outer shell with its super
anti-erosion character could be installed in ocean coast weather.
Insulation Layer: High-density polyurethane integrated foam-forming with twice
slaking treatment, preserves hot water constantly as long as 70~80
Supporting Bracket: strong stainless steel plate with a good weight bearing and wind
resistance (140 km/hr), stainless steel ensures a long lifespan to
acid rain, easy installation, universal bracket suitable for either
flat or slope roof installation.
Accessories: Stainless bolts & nuts, water-proof silicon rubber, anti-aging
dustproof rubber seal, plastic pipe holder and ventilating cap to
ensure their lives as long as other parts of the system
1. It can withstand pressure of tap water when it works, and copper
coil in tank bear pressure.
2. Use in any time: it adopts advanced design idea and integrates
with high efficiency preheated patent technique.
3. High quality SUS304-2B stainless steel for inner water tank,
processed by argon arc welding technique, under
strict quality control system, tank will never rust and leak.
4. Relevant accessories are optional instead of compulsory, client
can choose some or none according to actual need.
5. 6. It can produce hot water with constant temperature.
7. It’s indirect solar system, so water quality is superior, much
cleaner than direct solar system.
8. Time of uploading water is cut, 24 hours water supply on
condition that pipeline is working.
9. Life duration: 15 years, warranty: 5 years
10. OEM/ODM offered
