Solar Hot Water Heating System

Product DescriptionA 50/50 propylene glycol and water mixture from the collectors through a coil of pipe in the solar tank, and then is pumped back through the collectors. The potable water is warmed by heat transfer through contact with the pipe. These systems are pretty much the only choice in very cold climates. When there is not enough energy for sun, an electrical or gas back up element will be automatically switched on by controller.Product Parameters TypeVertical Pressurized Solar Water Heater TankCapacity150L200L250L300L400L500L700L1000LInner tankSUS304 2Bδ1.2φ360SUS304 2Bδ1.5φ450SUS304 2Bδ1.5φ480SUS304 2Bδ1.5φ480SUS304 2Bδ2.0φ580SUS304 2Bδ2.0φ580SUS304 2Bδ2.0φ580SUS304 2Bδ2.5φ800Outer tankColor Steelδ0.5φ470Color Steelδ0.5φ550Color Steelδ0.5φ580Color Steelδ0.5φ580Color Steelδ0.5φ700Color Steelδ0.5φ700Color Steelδ0.5φ700Color Steelδ0.5φ1000PU Foam Insulation55mm50mm50mm50mm60mm60mm60mm100mmCoil heat exchangerCopper coil φ12/Stainless steel φ15.88/Flexible pipe φ19Working PressureSuggest 2bars to 6barsP/T ValveRelease when pressure is over 7bars or tempertuare is over 95 °CElectric booster1.5KW 220V or 2KW 220V normallySuitable people3persons4persons5persons6persons8persons10persons14persons20persons  Company ProfileSince its establishment in 2002, Shandong Longguang Tianxu Solar Energy Co., Ltd (hereinafter referred to as "Tianxu") has always engaged itself in the R&D, production, sales and service of high borosilicate glass tubes and new energy products including solar water heaters, solar vacuum tubes, solar heat collecting project, air source heat pump, photovoltaic products, etc. Tianxu has 10 sets of electric furnaces, 70 sets of solar vacuum tube production line and 3 sets of solar water heater production lines.
