Abstract: The invention relates to a system (100, 300, 400) for storing and transferring heat. The system (100, 300, 400) comprises at least one resistor (101, 301, 401) for producing heat energy from electrical energy, at least one heat storage module (102, 302, 402) comprising solid material for storing the heat energy produced, and a heat transfer mechanism (103, 303, 403) for transferring heat from the at least one heat storage module (102, 302, 402) into a heat transfer system (104, 304, 404). The heat transfer mechanism (103, 203, 403) is a closed gas loop or a thermosiphon system. The specification further relates to a method for storing and transferring heat.
