An electric element provides backup heating to ensure hot water all year round.Pressurized storage tank and strong suppotive aluminium mounting frame to make a compact solar water heater.Basic OperationFlat plate absorbers absorb sunlight and convert it to usable heat, which is transferred to the heat pipes welded to the underside of the solar absorber sheet. The heat pipes contains a small amount liquid which forms steam when heated, rapidly transferring the heat up to the header pipe which is connected to the storage tank. Water in the storage tank gradually circulates through the header pipe heating up the tank throughout the day.FeaturesTechnical Specifications•High efficiency heat pipe type flat plate collector•Anti-freeze design•Well insulated solar storage tank•Thermosiphon or pump forced compatibleFlat Plate CollectorAbsorber:0.3mm BlueTec solar ALAbsorber Welding: UltrasonicAbsorber emittance: 5%±2%Absorber absorption: 95%±2%Heat pipes: 14(head)x6(thickness)x1700(length)mmHeat pipe spacing: 110mm (total of 8 heat pipes)Glass: 3.2mm, 92% transmittanceCollector Body: 6005-T5 black anodized ALBack Sheet: 0.4mm galvanized steel sheetInsulation: 20mm FP Resin sides 20mm rock wool bottomStorage TankInner tank: Food grade SS304 (SS316 optional)Outer tank: PVDF coated steelInsulation: 50mm high density PU foamElectrical heating element: 1.5kWSafety Valve: 1MPa / 99oC PT valveSystemMax Pressure: 600 kPa
