Low Pressure Vacuum Tube Solar Hot Water Heater with Backup Electrical Heater

Working principle1. Non-pressure solar water heater of all glass evacuated tube collector integrated with storage tank, are ideal for use in houses and other applications where cheap, reliable hot water supply is required. They are simple, economic and practical. 2. As the specific gravities of hot water and cold water are different, cold water goes downward and hot water goes upward. 3. When cold water in evacuated tubes is heated, it becomes lighter and goes to the water tank, while cold water in the tank goes down to the evacuated tubes 4. Through this circulation, the cold water in the water tank will be gradually heated. Feature of solar water heater  1. This is a natural circulation system. Cold water is heated in vacuum tube, and then rises to the top of tank.2. Storage tank does not bear high pressure, and hot water flows out by gravity.3. Its assistant tank will make up water automatically when water in storage tank is being used up. Whenwater is full, it will stop making up water itself, no any manual operating.4. Easy installation and free maintenance. Advantages of solar water heater1. It operated completely automatic if connect with intelligent controller.2. Simple structure, easy plug-in installation, can be installed both on flat and inclined roof, and can be used with an auxiliary electrical heater as to provide hot water without sunshine.3. Superior heat preservation ensured by one-off molding polyurethane foam with thickness 65mm. Can keep warm efficiently for 3 days4. Stable and reliable performance, well wind resistance.5. Meet the mankind healthy bath standard: The material of inner tank is SUS304-2B stainless steel sheet; The silica gel ring sealing has a long life against the erosion and it is not harmful to health.                        Trade Items Of Product PaymentT/T,L/C,West Union,PaypalMOQ1 SetPortShanghai/NingboPackageStandard carton for whole container productsWooden Box Package for sample orderDelivery7 days after deposit received.Supply Ability100000  Sets / YearAbout UsWe Yangyang Trade Company is a leading supplier of solar water heaters and related products with over 10 years' export experience. Main market covers India,Vietnam,Middle East,East Africa,etc.......  Products include Non-Pressure,pressurized solar water heater,flat plate solar water heater,solar collector project with all variety of configuration. Do welcome to join us for a same concept----Making a friendly environment,solar water heater,go GREEN!!!! Our Service1.) Inquiry Response: Your Inquiry will be replied within 24 Hours 2.)
