1. A device for storing energy by conversion of electrical energy into thermal energy, comprising:
- a vapor container;
a storage medium coupled to the vapor container;
a water pipe adapted to guide water into the vapor container;
a pump connected to the water pipe;
an electrically driven plug-in heater arranged in the vapor container to electrically produce overheated vapor from water guided into the vapor container;
a central pipe arranged in the vapor container, the central pipe surrounding the plug-in heater and comprising a vapor outlet at an upper end and an inlet at a lower end; and
exhaust vapor pipes connected to the vapor container,wherein the overheated vapor produced by the plug-in heater circulates within the central pipe to the vapor outlet and outside the central pipe back to the inlet, wherein a thermodynamic effect transmits heat to the storage medium.

Abstract
A method and a device for storing electrical energy by means of conversion into thermal energy and reconversion into electrical energy are described. In a pipe system as a vapor container, there is produced overheated vapor by use of electrically produced heat, said vapor transmits in turn the heat to the walls of the walls of the vapor container (1) under-utilization a thermodynamic effect, said walls transmitting the heat to the storage medium (2) by use of additionally arranged welded plates.
