Abstract
A radiant electric heater includes a base (2) of thermal and electrical insulation material having a surface supporting at least one heating element (3) in the form of an elongate electrically conductive ribbon (4). The ribbon (4) is supported on edge and is partially embedded in the surface of the base (2). A rod-like temperature-responsive device (7, 8) extends at least partly across the heater from an edge of the heater and over the at least one heating element (3). The surface of the base (2) is provided with a shallow recess (9) beneath the rod-like temperature-responsive device (7, 8) and the ribbon (4) is partially embedded in the shallow recess (9) to a lesser extent than in the surface of the base (2) at either side of the shallow recess.
