Claim 8:
9. An electrical tubular heating element for producing a desired heating output, the electrical tubular heating element comprising:
a tubular metal sheath having an interior; and
an electrical heating element positioned within the interior, the electrical heating element formed from a resistive rod and being electrically insulated from the tubular metal sheath at least in sections by an electrically insulating material, the resistive rod, from which the electrical heating element is formed, is penetrated by an opening,
wherein the opening penetrating the resistive rod is filled with the electrically insulating material,
wherein the electrical heating element is arranged in the interior of the tubular metal sheath and the sections of the electrical heating element are electrically insulated from the tubular metal sheath, and
wherein, after the electrical heating element is prepared, the opening is filled with the electrically insulating material by pushing a bar constructed of the electrically insulating material into the opening.
