solar water heater system

unpressuried soalr water heaters 1.vacuum tube solar water heater/unpressurized solar water heater The Income high efficent vacuum tube collects heat highly and effectivel The flexibility of red copper film is stronger,it resists severely cold.The long term using effect is stable under the super high temperature.Under the same sunshine condition,heat absorption is more formidable,under the severely cold environment,the loss of heat is less.When the area of heat collecting is the same,the quantity of heat absorption is bigger.Under the homoclime condition,it gets hot quickly,the hot water is more,because of the solution to the difficult problem that film falling off and performance weaken afrer exposing without water,the service life is longer. 2.Inner tank food grade stainless steel inner tank,the security is garrenteed. Adopt the thicked imported food grade stainless steel plate of SUS304-2B,the performance is outstanding,be using full automatic argon arc welding craft,specially the newest introducted seamless welding apparatus.Before leaving the factory,they are pressurized(0.2MP)to detect leaks completely,guaranteed that there is no leakage in the inner tank. 3.Outer tank---color steel/stainless steel The end cover of water tank is inner buckled,firm and artistic The imported galvanized cold rolled steel plate,disposed by advanced craft processing after the die models,and then connected by seamlessly inner buckled craft.Its anti-corrosion and anti-shrinking ability is stronger. 4.bracket Intimate designing,specialty makes the Income brand,obtain the design patent. The bracket material is coorrosion preventing,and thickened galvanized by two-sided,the cold rollong steel plate is spurted processing.By taking the bridge structure craft and the streamline form design,make the aapearance elegant.The bracket is anti-acid rain,anti-gale,against ultraviolet radiation,follows mechanics princiole.The quality of the water tank volume and the vacuum tube are reasonable proportioned,and the heat insulating layer density is even,the thermal propertied enhance enormously,the loss of heat drops to the lowest,the service life may reach 20 years long. 5.Heat-insulating layer:The performace of heat preservation is ultra good.The hot water is more lasting.The outside end cover of the water tank adopts the 7cm inner buckled craft,so the heat preservation effect is stronger.
