15tubes Vacuum Tube Solar Water Heater

Stainless steel solar water heater 1. OEM offered 2. More appealing 3. High efficiency 4. Most economical Stainless steel solar water heater Features description: 1)Stainless steel plates, welded by argon arc. Water is pure and drinkable 2) Heat insulation of water tanks adopts polyurethane foam and the thickness is 55mm 3) Silicon rings to connect and seal them 4) The tubes and supports are adjustable. The power bearing is average and can assure the vacuum tubes to use for a long time 5) Whole glass vacuum tubes adopt super hard borax and silica glass 6) Absorption rate: =93%, thermal radiation rate: =6% 7) It resists 25mm hail and the using life can last 15 years 8) Temperature when exposed to sun without water: 250oC, 2.5 hours to boiling point if using single tube 9) If you use electrical appliances to aid heating and to switch off the power supple before bathing 10) Please test the water temperature before using, in order to avoid scalding 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). 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). Water tank shell: Stainless steel same with inner water tank as outer shell is much more durable and super in anti-erosion aspect, much more durable 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: Stainless steel plate with a good weight bearing and high wind resistance design (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. 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   /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
