Abstract
Electrical heating element 1, preferably for the ignition of biomass heating systems such as pellet stoves, with an elongated coil carrier 2 that is made of a thermally resistant, electrically insulating material and is designed to accept a heating wire coil, where the heating wire coil is held spiral-like on the outside the coil carrier 2 and is enclosed by a sleeve tube 4 also made of a thermally resistant material. The coil carrier 2 and the sleeve tube 4 delimit an air channel 5 through which the heating wire coil passes. According to the invention, the coil carrier 2 comprises at least two adjacent coil carrier shell parts 6, 6' that extend symmetrically to the center axis 8 of the heating element 1 in the longitudinal direction of the coil carrier 2.
