Abstract: A hob plate above a radiant heating device and a safety temperature limiter between said radiant heating device and hob plate, which safety temperature limiter is designed to deactivate the radiant heating device when a switch-off temperature is reached. To actuate the radiant heating device, a cooking vessel is first placed on the hob plate above the radiant heating device and then the radiant heating device is activated and at the same time detection of a first switch-on time starts. When a switch-off temperature is reached at the safety temperature limiter, the radiant heating device is deactivated by said safety temperature limiter. The first switch-on time that has elapsed up to that point between activation and deactivation of the radiant heating device is detected and compared with a predefined limit switch-on time. If the first switch-on time lies below the limit switch-on time the radiant heating device is switched off.
