Product Name: Domestic Compact Pressurized Solar Hot Water Heater (STH-200L) Model NO.: STH-200L Certification: CE, ISO9001, CCC Composition: Tank Insulation Collector Components: Glass Vacuum Tube Interior Material: Stainless Steel Pressure: Pressurized Structure: Compact Type Max. Capacity: 100-200L Capacity: 200L Vacuum Tubes: 58mm X 1.8m, 20 Tubes Outer Tank: PVDF, 0.4mm Inner Tank: SUS304, 1.5mm Heat Pipe Condenser: SUS316L Stainless Steel Bracket: Galvanized Steel, 1.5mm Inlet /Outlet: 3/4" Working Pressure: 6 Bar Warranty: 3 Years Trademark: Suntask Transport Package: Cartons /Wooden Pellet /Wooden Box Specification: STH-150L, 200L, 300L Origin: China HS Code: 8419191000 Product Description Domestic Compact Pressurized Solar Hot Water (STH-200L)Model: STH-150L, STH-200L, STH-300LNew Integrated Pressurized solar water heater: STH with 316L for blind tubeFor our compact pressurized model STH we have special design: We use 316L material for blind tube instead of copper caecus tube, because for copper blind pipe after some period with the high temperature and high pressure, or in the water quality inferiority area, it will face corrosion and will happen blind pipe perforation phenomenon or blind pipe leakage. This new blind pipe is composed of 0.9 mm stainless steel 316L stamping with the red copper gasket.New Design ADVANTAGES1. Slope roof and flat roof avaliable.2. Looks more beautiful.3. Inlet and Outlet hole at the back of the tank, any angel of roof is suitable.4. Electric heater on the tank cover(side)5. SUS316L stainless steel heat pipe condenserSPECIFICATIONS1.

OptionalSpare Tubes: 3.5 USD/PcController: SR609, 35 USD/PcElectric Heater: 1500W /2000W, 10 USD/PcFEATURE1. Highly efficient absorber of high performance with daily average efficiency over 50%;2. Start up quickly, heat pipe transfer the heat energy into the storage tank in one direction.3. Withstand pressure of 6 Bar, can be connected directly with city water.4. No water inside the evacuated tubes; The solar water heater can still in service even with several tubes breakage;5. Highly efficient insulation with polyurethane foam;6. Simple structure, easy to assembly and install, diffuse flat plate reflector can be assembled easily with its module structure;7. Can be used all year round in the cold climate;8. Can be used together with Auxiliary electric boost;9. Long service life, can be used as long as 15 years.Solar keymark certificate types:SCM12-58/1800SCM15-58/1800SCM20-58/1800SR10-58/1800SR15-58/1800SR20-58/1800SR30-58/1800*************SRCC certificate typesSR10-58/1800SR15-58/1800SR20-58/1800SR30-58/1800ModelsSTH-150LSTH-200LSTH-300LCapacity(Liter/Day/60C)150200300Effectivecollectorarea(M2)1.922.573.87No.oftubes152030Vacuumtubes(mm)58*1800HeatpiperedcopperCondenserSUS316L,dia14mm,bodydia8mmInnertankSUS304-2B,1.5mmOutertankPVDF,0.4mmBracketgalvanizedsteel,1.5mmInlet/outlet3/4″Max.pressure12bar
