Abstract
An electrical heating device includes a flat heating block, which is held in a housing forming oppositely situated frame openings and which comprises parallel layers of heat dissipating and heat generating elements. The heat generating elements on the face side have fitting elements projecting beyond the heating block, and fitting element receptacles assigned to these fitting elements are formed on the housing. The fitting elements and the assigned fitting element receptacles of different heat generating elements are formed such that the heat generating elements cannot be inserted at just any random place in the housing.
