Electric heating device, essentially characterized by being constituted by a piece in the form of tile, tile, tile, terrazzo or similar, equipped on its rear face with a group of channels, at least two of them larger and others smaller in the form of grooves, which communicate to each other the older ones, whose channels and grooves are filled with an electrically conductive mass, such as graphite, plumbago or other matter or composition of similar properties with a binder constituting an electric conductor circuit embedded in the piece, also possessing two lamellae, springs or other contactor means so that, when coupling said pieces on the surface to be coated, in which previously appropriate conductors insulated from the wall and connected to the network have been assembled, the embedded circuit is heated transmitting the heat to the covering piece that supports it.
