  2 Features description Non-pressurized solar water heater is such kind of a most economical system with high efficiency at the same time. It works depending on the gravity of water, so it's much better to be installed on the slope or flat roof as top as possible to get enough hydraulic pressure. A simple assistant tank can be equipped for tap water refill automatically or with an intelligent controller to control the startup of auxiliary heating device at the same time.    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: Imported color steel plate, with its outer coating treatment ensures a long life 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: 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. 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. 4 High efficience project water tank and solar collector                       
5 Optional DevicesAssistant 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. 6 Service of Sanneng Solar Water Heater Co., Ltd  Fast response: Your inquiry will be replied within 24 hours via e-mail or online messenger; Technical support: You have more than 10 years experience from SANENG SOLAR for  product suggestion, installation guidance, market analysis, etc; OEM & ODM: We welcome OEM & ODM requirements for solar collector, storage tank, installation frame,  and even for some outsourcing equipments;  Sample checking: In spite of quality control in production, samples will be selected  and installed to check prior to delivery;  Minimum order quantity: We offer sample sample manufacturing for customers to  check SANENG quality and service;  Shipping service: SANENG company offers to arrange goods shipment to abroad ocean  port or inland site, and if necessary to make goods insurance, customs clearance, etc;  Import certificates: SANENG company offers to make Certificate Origin CO, FORM A,  FORM E, FORM F, customs certification, etc;  6 Remarks     1.Lead-time: 7-15 working days after receiving payment. 2.Payment Term: T/T, L/C, Western Union. 3.Warranty:5Years for the full system,15Years for the vacuum tube,and 1year for accessories.  4.Trade Term: FOB, CFR and CIF.   we can customize according to customer's requirement   Contact: Mr. sunny      Mobile: (00)86-18357309575  Skype:sunny-yu77
