Is it harmful to turn on the water dispenser without heating the water boiled by the gallbladder?

If you boil the water in the water purifier, there is no problem. His principle of boiling water is equivalent to a domestic water dispenser, and it will not be heated repeatedly. The water from ordinary drinking fountains will be heated repeatedly to form dry boiled water. This thing is not only harmless, but also better than ordinary drinking fountains. I hope my answer is helpful to you and can be adopted.
