Hot water bag filled with electricity after the expansion of a very strong, strong drum, cold and deflated back. I would like to ask how to do? Hot when you can deflate it?
Hello, the principle of thermal expansion and contraction, hot water bag inside the water after the irrigation is not recommended.
When the hot water bag has no temperature can be opened to open some gas but pay attention to the point where the charge should not touch the water. Don't often bleed, so easy to loose the lid of electric hot-water bottle is not durable.
It is best not to, the general charge is like this, when the inside of the heated gas will be generated by the expansion of hot water bags, but a good heating will be returned to normal after a while do not worry.
