Abstract
A heat accumulator element comprises a container containing water sealed therein, the inside of the container being provided with a gas phase. Heat is directed at the outer surface of the container and accumulated in the liquid as sensible heat, and the volume change of the liquid caused by a change in the temperature is absorbed by the gas phase, so as to reach an accumulating temperature up to about 300.degree.
