It incorporates separate fastening grilles (1), means of heating (5) positioned between the fastening grilles (1) which are electrically actuated from a control panel (2) and which consists of a radiating plate (5) which has, on its two surfaces, tracks made in electro-resistant material configuring electrical resistances on each surface which radiate heat in opposite directions when current is applied thereto. It has a U-shaped base member (6) in whose central portion are positioned central (7) and lateral (8) perpendicular flanges which facilitate the fitting of the radiating plate (5), and footings (9) of the fastening grilles (1). It also has a sealing clamp (3) which perimetrically grips the fastening grilles (1) except by their base, thus establishing the sealing of the heater.
