1. A radiant heating device for providing radiant heat in a passenger compartment of a motor vehicle, comprising:
a heating surface for outputting thermal radiation;
a first temperature sensor for detecting a first temperature at a point of the heating surface and for providing a corresponding first temperature indication;
a second temperature sensor for detecting a second temperature over an area of the heating surface and providing a corresponding second temperature indication; and
a heating element for providing heat output to the point of the heating surface and the area of the heating surface,
wherein the point of the heating surface lies within the area of the heating surface, wherein the second temperature sensor for detecting the second temperature is arranged two-dimensionally between the heating element and the heating surface, in order to provide the second temperature indication in a way corresponding to a distribution of local temperatures of the heating surface.
