1. A surface heating device for heating a wall, comprising:
(a) a heating layer which can be applied to the wall to be heated and comprises at least two conductivity additives and at least one binder, the conductivity additives comprising graphite and carbon black, the binder comprising an inorganic binder, and the heating layer being free from electrically conductive carbon fibers and carbon nanotubes, wherein the graphite is synthetic in origin, wherein the heating layer can be operated with a protective ultralow voltage in the range from 5 V to 48 V,
(b) two electrically conductive contact elements, which can be or are arranged on the heating layer in such a way that the electrical voltage can be applied to the heating layer, and
(e) two transition elements which are or can be mounted to the contact elements, each of the two transition elements comprising a retaining element for at least one of positively and nonpositively securing the transition element on the wall.
