The invention relates to a device for heating a medium and air. A heating source (1) generates thermal energy by burning a fuel-air mixture. A heat exchanger (2) is used to heat air guided along an outer side, has an interior (20) into which flue gas produced during burning of the fuel-air mixture passes, has a fin structure (21) on the outer side, and transfers thermal energy to the medium tube (4). The electrical heating element (3) generates thermal energy, wherein the heat exchanger (2) has integral structures for accommodating both the electrical heating element (3) and the medium tube (4). The medium tube (4) and the electrical heating element (3) run around the interior (20) of the heat exchanger (2).
