Example embodiments relate to a device for heating room air and a liquid. Room air enters and exits the device via an air inlet and an air outlet, and the liquid enters and exits the device via a liquid inlet and a liquid outlet. The heat transfer device transfers the thermal energy produced by an energy unit to the liquid in an interaction area of a medium line. A conveying device moves liquid between a medium container and the medium line. A control unit controls the conveying device and/or the energy unit. In case the device is intended to heat only room air in an air mode, the control unit, in a preparation step, controls the conveying device and/or the energy unit such that liquid runs out of the medium line due to the gravitational force and/or liquid in the medium line is heated up to an evaporation temperature.
