Heating by electricity obtained by closing an electric circuit (19-21) by means of an extremely thin highly conductive band, whose thickness is measured in microns, that winds in the form of a serpentine round metal laminae (30), the external surfaces of which are treated with insulating means, forming a compact panel (10), generating and at the same time diffusing heat at a temperature substantially used for heating and for other purposes. |
