A radiant electric heater is manufactured by a method which involves providing a base (2) of microporous thermal and electrical insulation material having at least one groove (9) formed in a surface thereof, and providing an elongate electrically conductive strip (5) to serve as a heating element (4). The elongate electrically conductive strip (5) is located edgewise into the groove (9) and surface pressure is applied to the base (2) of microporous insulation material in a region (11) adjacent to the strip (5) to deform the base (2) and to urge microporous material of the base into contact with the strip (5) so as to secure the strip in the groove (9). <IMAGE> |
