Copper Coil Preheat Solar Water Heater Features description
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 continous and not limited by water storage tank
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 convinient hot water use.
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 resistantce (380oC).
Inner water tank: Food-grade stainless steel SUS304-2B as inner tank keeps the water clean and drinkable, together with advanced welding technics to ensure a long lifespan ( more than 15 years).
Water tank shell: Color steel with surface advanced processed 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 hours.
Supporting Bracket: strong hot-dip galvanized steel plate with good weight bearing and wind resistance (140 km/hr), outer painting or baking process 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
Optional Devices
Assistant tank, to automatically feed tap water into storage tank to keep it sufficient always
Electrical heater, as an auxiliary heating element in case of raining or clody days so as to ensure a continous hot water supply
Intelligent controller, automatically controls water refill and startup of auxiliary heating devices
Anode Magnesium bar, good at eleminating water scale with consumption of itself gradually.
Warranty: 3 years international responsibility for integrated system exchange and 15 years for glass vacuum tube compensation due to original quality problems
