1) Copper coil as twice heat exchanger makes a pressurized and instant solar water heating system
2) Hot water output is continous and not limited by water storage tank
3) An assistant tank can be quipped for 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 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 (15 years).
Water tank shell: Imported color steel plate or PVDF plate, much durable with its outer coating treatment even to ocean coast weather.
Insulation Layer: Germany-imported polyurethane integrated foam-forming with twice slaking treatment, preserves hot water constantly as long as 70~80 hours.
Supporting Bracket: Galvanized steel plate with a good weight bearing and wind resistance(140 km/hr), outer powder coating or pain baking treatment 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 snowing days so as to ensure a continous hot water supply
Intelligent controller, automatically controls water refill and startup of auxiliary heating device, more intelligent operation
Booster Pump, a choice for those area without tap water or with a unstable water supply.
Warranty: 3 years international responsibility for integrated system and 15 years for glass vacuum tubes due to original quality problems.
