I would like to ask how to drain the hot water bag, each filled with the feeling to burst.
Because of the heating of the water will produce water vapor steam no place to vent will support a large hot water bag hot water bag will have an exhaust hole over a period of time will be redundant water vapor will not have too much problem
The general charge can not be deflated, you can put the hot water bag in the cool place, so good. Because the charge is vaporization of water into water vapor, the bag pressure increases, as long as the decrease of pressure even liquefied gas line!
The heat will swell. However, each has a vent valve.
