Solar energy water heater

Solar energy water heater Model: CH-62 Non-pressurized solar energy water heater Working Principle of the solar energy water heater: 1,Vacuum tube absorb solar energy, heating the water inside of vacuum tube 2,According to density difference, the cold water through down into vacuum tube, and hot water flow up into solar tank 3,After circulation again and again, all of the cold water will be heated to hot water and storaged in solar tank. Features of solar energy water heater: 1,The solar water heateris non-pressurized, drop water must rely on height difference, so the solar heater must to install higher than users 2,Exhaust vent or Exhaust pipe is most important for protection the solar heater system 3,Material of solar energy water heater: a)Internal tank: SUS304-2B b)Outer shell: Red Color armor plate c)Frame: galvanized steel with powder coating d)Insulation layer: polyurethane foam e)Vacuum tube: high borosilicate glass with AL/N/AL coating f) Specification of vacuum tube: φ47mm/1500mm or φ58mm/1800mm g)Quantity of tubes: 12,15,18,20,24,30,36 h)Capacity: from 60Liters to 300Liters 4,Accessories: optional a),Assistant tank: Assistant tank have a float valve, when you put water into solar tank at first time,if the solar tank is full,the assistant tank will controll to stop into water. When the water in tank have been used or evaporated, the float valve will drop down, and cold water will into assistant tank again b),Magnesium rod: Soften water, protection solar tank c),Electric heater: assistant heating by electricity when the water could not satisfy your demand. d),Controller: Controller can showed water level and water temperature, also can setting time for put into water and assistant heating 5,Usefull life : 15years
