Example embodiments relate to a device for heating a medium and air. A heating source generates thermal energy by the combustion of a fuel-air-mixture. A heat exchanger serves to heat air passed along an exterior side, has an interior space into which flue gas generated during combustion of the fuel-air-mixture flows, has a fin structure on the exterior side, and transmits thermal energy to the medium pipe. The electric heating element generates thermal energy, the heat exchanger having integral structures for accommodating the electric heating element and the medium pipe. The medium pipe and the electric heating element are guided around the interior space of the heat exchanger.
