The water enters the bottom of the collector and rises to the tank as it warms. The advantage of this system is that solar heat is stored in 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.Product DescriptionStorage TankInner TankSUS304-2B food-grade stainless steelInner Tank Thickness0.4mmOuter TankStainless steel, 0.31mmInsulating LayerPolyurethane Foam 50mmVacuum TubeMaterial 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 emsision coefficient5 ± 1 %VacuumP≤5.0*10-3 PaStagnation Temperature>200°CAverage heat loss
