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