A heating element for heating gases to high temperatures includes at least one tube arranged for the flow of gas to be heated and an electrical heating wire in the tube, which transfers heat to the gas flowing past. A process heater and a corresponding heating element are provided to permit generation of gas temperatures up to 1000&#xb0; C. or above and having a lifespan 10 times longer than conventional heating coils. The heating wire is formed as a heating rod extending along the tube axis, whose maximum clear distance to the inner wall of the tube does not exceed a value of 10 mm over at least 80% of the circumference and/or at least 80% of the overlapping length of the tube and heating rod.
