Abstract: A ventilation-heating apparatus comprises a fresh air passage with which a fresh air ventilation mechanism is associated and which opens into a room-side inflow air supply opening. The ventilation-heating apparatus further comprises a room air passage with which a room air ventilation mechanism is associated and which opens into a room-side air removal outlet opening. Fresh air and room air passages are passed through a heat exchanger which is suitable for the transfer of heat from the room air passage to the fresh air passage. An electrically heatable metallic heating element is provided in the region of the fresh air passage. A suitable heat storage element is associated with the heating element for the storage of the heat produced.
