Abstract
A heat accumulator having a housing to receive a heat storage medium, a heat storage medium received in the housing, and a heat exchanger, in which a heat carrier fluid can be transported and which is arranged so that heat can be transferred from the heat storage medium to the heat carrier fluid. The heat accumulator comprises an electrical heating means which is configured to convert electrical energy into heat energy. The electrical heating means is arranged so that it heats the heat storage medium during operation, wherein the heat storage medium heated by the electrical heating means is a metal. In addition a corresponding method is disclosed.

A heat accumulator comprising
- a housing to receive a heat storage medium,
- a heat storage medium received in the housing and
- a heat exchanger, in which a heat carrier fluid can be transported and which is arranged so that heat can be transferred from the heat storage medium to the heat carrier fluid,
- wherein
- an electrical heating means is provided which is configured to convert electrical energy into heat energy,
- the electrical heating means is arranged so that it heats the heat storage medium during operation, and
- the heat storage medium heated by the electrical heating means is a metal.
A method for operating a heat accumulator,
- wherein heat energy is transferred from a heat source to a heat storage medium which is received in a housing of the heat accumulator, and
- wherein heat energy is transferred from the heat accumulator to a heat carrier fluid which is transported through a heat exchanger,
- wherein
- as a heat source an electrical heating means converts electrical energy into heat energy and
- the heat energy generated by the electrical heating means is transferred to a metal as a heat storage medium.
