Abstract
A radiant electric heater includes at least first (7) and second (11) adjacent heating zones. The first heating zone (7) includes a first heating element portion (5) and the second heating zone includes a second heating element portion (9). An electrical terminal (19) is provided at a periphery of the heater for connecting the first and second heating element portions to a source of electrical energy. The heating element portions (5, 9) are integral with conjoined ends connected to a first electrical connector (21), with one free end connected to a second electrical (23) connector, and with another free end connected to a third electrical connector (25). The first, second and third electrical connectors include means for connecting to the heating element portions in such a way that the heating element portions are not deflected from their intended path to any substantial extent.
