The hot water bag is the use of heating principle, is installed inside the electric heater, after charging to the inside of the water heat, automatically cut off, water will drum up because of heating, water molecular diffusion, so the expansion, you want to use the time after it, I suggest you once charged to the inside of the water to the cold, that is used in heating, hot water bag, not in the expansion.
