An electric heater in the form of a wall panel, having an electric heating resistor (4) embedded in a refractory material in the form of a plate or panel. The electric heater is characterised in that it has, on the exposed surface thereof (6), ceramic tiles (7), particularly faience tiles, defining, with a frame (8) of a suitable material, a lost framework (9) within which refractory concrete is poured (10), a metal mesh or the like (11) supporting the heating resistor (4) being embedded in the concrete. A method for making such a heater is also described. |
