Abstract
A radiant electric heater comprises concentrically-arranged heating elements separated by a dividing wall to form inner and outer heating zones, the heater having a peripheral wall. A tunnel extends between the peripheral wall and the dividing wall. A rod-like temperature-responsive device extends through the tunnel and across the inner heating zone. An end portion of the inner element extends along the tunnel. A terminal block is located at the periphery of the heater, end portions of the inner and outer elements being electrically connected to terminals provided in the terminal block. An elongate electrically conductive link is provided having a first end electrically connected to one terminal and bridging an end portion of the outer element connected to another terminal, the link being profiled such that a second end thereof is located within the tunnel and connected to an end portion of the inner element.
