A radiant electric heater comprises at least first and second adjacent heating zones (8, 12), the first heating zone (8) including a first heating element (6) and the second heating zone (12) including a second heating element (10). The heating elements are supported relative to a base (4) of thermal and electrical insulation material. Terminal means (30) is provided at a periphery of the heater for connecting the first and second heating elements (6, 10) to a source of electrical energy. The heating elements (6, 10) are formed from a single elongate electrically conductive material, the heating elements having a conjoined first terminal region (20) connected to a first electrical connector (32) at the terminal means (30), having a free second terminal region (18) connected to a second electrical connector (34) at the terminal means (30), and having a free third terminal region (16) connected to a third electrical connector (36) at the terminal means (30). At least one of the first, second and third terminal regions (20, 16, 18) traverses the second heating zone (12) for connection to the respective electrical connector (32, 34, 36).
