The improvements are applicable to heaters consisting of a metallic pan 1 inside which is housed a thermally and electrically insulating support 2, on which support 2 are located and secured the corresponding electrical resistance elements 3 for forming, together with a ring 4 which is also insulating, the heater which can be applied to vitroceramic plates or similar electrical domestic appliances. The improvements centre on the fact that, crosswise with the channels 7 for positioning the electrical resistance elements 3, the insulating support 2 includes furrows 6 in which is deposited ceramic glue in the viscous state so that, after the arrangement of the actual electrical resistance elements 3 in the channels 7, setting of this glue poured into the furrows 6 gives rise to the securing of said resistance elements 3 on the insulating support 2. <IMAGE>
