Abstract: A heat accumulator device is provided having a metal phase-change material as an accumulator material, the heat accumulator device including at least one a holding chamber having a holding space for the accumulator material, a housing for the holding space, at least one heat input apparatus for inputting heat into the at least one holding chamber, and at least one heat output apparatus for outputting heat from the at least one holding chamber. A coupling region of the heat input apparatus, provided for thermal coupling to the accumulator material, and/or a coupling region of the heat output apparatus, provided for thermal coupling to the accumulator material, is arranged, at least in part, at a distance from the accumulator material.
