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