A temperature limiter (21) for a radiant heating element has an expansion bar (24) and a tube (25) of lower thermal expansion coefficient compared to the expansion bar. The tube consists of a radiation-absorbing material or is coated with such a material, for example cordierite, non-transmitting glass ceramic or quartz material. This causes a thermal delay and an increase in the switching amplitude while at the same time reducing the switching frequency. <IMAGE>
