Solar water heater Material of Inner Tank : SUS304-2B stainless steel.Material of vacuumtube:QB-AL-N/AL-diameter47*1500mm,58*1800mm.Material of Outer Tank:colour steel plate or aluminizing zincplate.Insulation :polyurethanewith super-thickness of 55mm.Material of Support :stainlesssteel.Reflector :diffuse reflection sheet.The thermosiphon solarenergy heater provides hot water with high pressure through highefficient copper coil in the hot water tank.In accordance withnon-pressure bearing style to use hot water directly from the watertank ,a 45-60 turns of copper coil is equipped to provide and area ofheat exchange of heat exchange of 1.2 sqm.When water flows into thecopper coil ,it absorbs the heat of the water in the tank via thecopper coil therefore the water tank is just a heat storage tank.Theadvantage of the system is that almost no water supply (except fillingup the tank sometimes) is needed for the water tank therefore nocorrosion or scaling is possibly occur.The desigh of the water tank isfor low to medium pressure ,so the gravity self-flow water tank or therelief valve is needed.It is strictly prohibited to connect it to thewater supply device with pressure.
