Simple description about this type of Vacuum tube non pressur solar water heater:
Non pressure solar water heater is such 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 for shower. A simple assistant tank can be equipped for tap water refill automatically or with an intelligent controller to control the auxiliary heating device and water refill at the same time.
Details:
Vacuum tube: Hail-resisting 3.3 borosilicate glass with high-tech single-target 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 380oC high temperature resistantce without peeling off the coating layer.
Inner water tank: Food-grade stainless steel SUS304-2B as inner tank keeps the water clean and drinkable, together with advanced argon arc welding technics to ensure it with a long lifespan (more than 15 years).
Water tank shell: Imported color steel plate, with its special coating treatment ensures a long life even to ocean coast weather.
Insulation Layer: High-density polyurethane integrated foam-forming with twice slaking treatment, preserves hot water temperature as long as 70~80 hours.
Supporting Bracket: Very strong hot-DIP galvanized steel plate with a good weight bearing and wind resistance design (140 km/hr), painting or baking process ensures a super mechanical performance and corrosion resistance, easy installation, universal bracket suitable for either flat and 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, automatically feed tap water into storage tank to keep it sufficient always
Electrical heater, as an auxiliary heating element in case of raining or cloudy days so as to ensure a continous hot water supply
Intelligent controller, automatically controls water refill and startup of auxiliary heating device, more intelligent system operation
