Abstract
A radiant electric heater (2) comprises a dish-like support (6) having a base layer (8) of thermal insulation material. At least one heating element (10) is supported relative to the base layer. A temperature-responsive device (16) has a rod-like component (18) secured at one end at a peripheral region of the dish-like support (6) and extends without support partly across the heater over the at least one heating element (10). Restraining means (30) is provided at a free end region (28) of the rod-like component (18). The restraining means (30) has a first portion (32) thereof secured in the base layer (8) of thermal insulation material and a second portion (34) thereof at least partially surrounding and spaced from the rod-like component (18) to allow limited relative movement between the rod-like component and the second portion of the restraining means (30). The restraining means (30) serves to limit displacement of the free end (28) of the rod-like component (18) away from and/or towards the base layer (8) of thermal insulation material.
