Solar Water Heating System Material of inner tank: SUS304Thickness: 1.2-2.5mmMaterial of outer tank shell: Colorful armor plateMaterial of stand: Galvanizes the steel plateVacuum tube: 58 x 1, 800mmCapacity: 80L,100L, 150L, 200L 250L ,300L and 500LHeat insulating layer: 55mm polyurethane foamingConfiguration: Closed-loop with copper coil inside tankPressure bearing: More than six barIt can work as usual even if one vacuum tube was brokenYou can get hot water on the second floor even if it was installed on the first floorThere is two kinds type for your choose: One copper coil in tank or two copper coils in tankIt can make building have a good looks, because the collector and tank is separated, you only need install collector on roof, then put tankFirstly, vacuum tube absorb sunlight then transfer heat to manifold by super-conduct heat pipe which has heat transfer medium in itManifold and tank will start to forced circulation by circulating heat pump, hotter water flow into tank and cold water flow into manifoldTwo copper coil tank can be connected with others heater, such as radiatorSolar Water Heater Parameterproduct model100L150L200L250L300L400L500Linner vessel diameter(mm)φ370φ370φ470φ470φ470φ600φ600water tank dimension(mm)φ470φ470φ560φ560φ560φ700φ700material and thickness of the inner vesselSUS304 1.2SUS304 1.2SUS304 1.5SUS304 1.5SUS304 1.5SUS304 2.0SUS304 2.0material and thickness of the shellColor Steel0.55 Color Steel0.55 Color Steel0.55 Color Steel0.55 Color Steel0.55 Color Steel0.55 Color Steel0.55 layerinsulation thickness(mm)50504545455050connector size of inlet&outlet3/4"3/4"1"1"1"1"1"Solar Water Heater Picture5 Containers are waiting for Dispatching
