Water is indispensable to the survival of mankind, important material, people can be a day without food but not a day without water, but not all can be healthy drinking water, the following will be under water in some degree the formation of nitrite and other poisonous and harmful material, will produce certain harm to human body, thus to arouse people's attention.

One, aging water: commonly known as "dead water", that is, a long time of storage of motionless water. Often drink this water, for minors, will make the cell metabolism significantly slowed down, affecting the body growth and development; The middle-aged and the elderly accelerate decay; A lot of place esophagus cancer, cancer of the stomach incidence of a disease increases day by day.

Two, thousand boiling water: thousand boiling water is boiling in the furnace for a night or a long time of water, and electric water heater repeatedly boiled water. This kind of water because cook too long, the water does not volatile substances, such as calcium, magnesium and other heavy metal components and nitrite content is very high. Long drink this water, will interfere with the gastrointestinal function, temporary diarrhea, abdominal distension; Toxic nitrites can also cause the body to run out of oxygen.

Three, not open water: people drink tap water, are chlorinated disinfection and sterilization treatment. Thirteen harmful substances can be separated from chlorinated water, among which halogenated hydrocarbon and chloroform have carcinogenic and teratogenic effects. When water temperature reached 90 ℃, halogenated hydrocarbon content from 53 micrograms to rise to 177 micrograms per kilogram, more than twice as many national drinking water health scale. Experts say drinking unboiled water increases the risk of bladder and rectal cancer by 21 to 38 percent. When the temperature reaches 100 ℃, the two kinds of harmful substances will be reduced greatly with the steam evaporation, such as inheritance boiling for 3 minutes, is safe.

Four, boiled water: some people are used to the remaining thermos of warm water boiled water to boil again drink, the purpose is to save water, coal (gas), saving time. But this "saving" is not worth it. Because water burned burn again, make moisture evaporate again, nitrite can be high, often drink this kind of water, nitrite can be contained inside body, cause toxic.

At present, there are still 70%-80% factories, hotels and teahouses inheriting and using traditional boiling water containers, which have heat preservation tanks, a large boiler for one time burning, repeatedly boiling water, constantly filling water and constantly heating, resulting in Yin Yang water, thousand boiling water and overnight water, which are harmful to human health as described above. The aeron energy-saving fresh water boiler adopts fluid stroke heating, and the tap water enters the cold water tank through the solenoid valve, and then enters through the connecting pipe from the bottom of the direct-flow heating box for heating; In once-through heating box heating process produces a large number of redundant heat recovery steam being imported exchange room, cold water tank at the same time to absorb a large amount of heat energy, preheat temperature and 50 ℃; And then through the pipe into heating box, from 50 ℃ heated to boiling point (100 ℃), only need to heat the 50 ℃. Ailong boiling water device because there is no heat preservation tank, the whole process is not repeated heating, heat preservation, is ready to use, with how much to burn how much, do not use water does not use electricity, fundamentally solve the thousands of boiling water, Yin Yang water (not open water), overnight water.
