200L Rooftop Pre-Heated Solar Hot Water Heater with Copper Coil for Domestic Hot Water

200L Rooftop Pre-Heated Solar Hot Water Heater with Copper Coil for Domestic Hot WaterSFD47205818 High absorption and low reflection solar water heaterSFD47205818 is a pressurized solar water heater with a copper coil (heat exchanger), the water tank itself is not under pressure. A copper coil is placed inside the water tank, and the water flows through the coil and is heated by the hot water in the water tank. The use of non-pressurized water tanks reduces costs. Use a copper coil (heat exchanger) to get pressurized hot water, and the bath is more comfortable and relaxing.SFD47245818 can be intelligently connected with gas water heaters to automatically control hot water effluent and maximize the use of solar energy.SFD47245818 provides fresh hot water for safer and healthier use. Size of Product ModelSFD47205818Capacity200LThe Number of users4-6 peopleInner tankSUS304, diameter 360Outer tankStainless steel,diameter 470mmWelding procedureAutomatic double - sided argon gas protection weldingInsulationPolyurethane 55mm, temperature drop 2ºC/12hBracketsStainless steel 1.2mm,20°/30°/40°/45°Solar vacuum tubesNet aperture area:2.268m2Quantity and specifications: 24pcs*58*1800mmMaterial: 3.3 high borosilicate glassCoating: AL/N/ALAbsorptivity>93%Reflectivity
