Features :
1. Solar hot water heaters uses the all-glass evacuated solar collector tubes as the heat-absorbing element.
2.The high vacuum degree of the clearance between the outer and inner tube reduces the heat emission
3.which is caused by convection and conduction.
4.The layer films (coating) of the all-glass evacuated tubes transfer the sun energy into heat energy.
5.The high absorption and low emittance rate of film is unique.
Detailes description
1.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 makes the efficiency not only improved by 12% but also with a high temperature resistantce (380oC).
2.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 it with a long lifespan (15 years).
3.Water tank shell: Imported color steel plate, with its outer coating treatment ensures a long life even to ocean coast weather.
4.Insulation Layer: Germany-imported polyurethane integrated foam-forming with twice slaking treatment, preserves hot water constantly as long as 70~80 hours.
5.Supporting Bracket: Hot-DIP galvanized steel plate with a good weight bearing and wind resistance(140 km/hr), super mechanical performance and corrosion resistance ensures a long life to ocean coast, easy installation, universal bracket suitable for either flat or slope roof installation.
6.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
Warranty: 3 years international responsibility for integrated system and 15 years for glass vacuum tubes due to original quality problems
