The invention is directed to a method for the manufacture of a heating unit comprising an insulating body having a front and a back side, one or several heating conductors arranged on the front part of the insulating body, and contact and fastening elements. The heating conductors are connected to the insulating body by means of the contact or fastening elements. To manufacture single- and double-faced heating units in a common process, it is proposed that in a first operating sequence the contact or fastening elements are rigidly fixed together with the insulating body by means of anchoring arrangements and that in a second sequence the one or several heating conductors are contacted with the contact or fastening elements.
