Best anti-erode material. Especially for the seaside area, such as East South Asia, etc.Feeding water automatic: With a special design, feeding water automatically, and ensure the outlet water as a stable temperature. Principle:Compact non-pressure solar water heater relies on the natural circulation of the water between solar tubesand the water tank. Thermosyphon systems work on the principle of heat rising. The water enters the bottomof the collector and rises to the tank as it warms. The advantage of this system is that solar heat is storedin a well-insulated tank, so hot water can be used at any time without the penalty of overnight losses.Moreover, the insulation of the tank can protect heat for 72 hours without heat loss. Specification:Storage TankInner TankSUS304-2B food-grade stainless steelInner Tank Thickness0.4mmOuter TankPVDF 0.4mm which is good at anti-corrosionInsulating LayerPolyurethane Foam 50mmVacuum TubeThe material of the glass tubeBorosilicate glassAbsorptive CoatingGrade ALN/AIN-SS/CULength of Outer Tube1800mmLength of Inner Tube1755mmOuter Tube Diameter58mmInner Tube Diameter47mmGlass Thickness1.6mmDistance between two tubes 75mmThermal expension3.3*10-6/ºCAbsorption coefficient 95± 1 %Thermal emission coefficient5 ± 1 %VacuumP≤5.0*10-3 PaStagnation Temperature>200°CAverage heat loss
