An improved heating device, characterized essentially by taking advantage of the cold air currents forcing its passage through a spirally wound resistance in a refractory and insulating base, with lateral fixing supports to a reflective medium-parabolic metal surface of the heat wave, which it is held by suitable means in the lower part of the doors to channel the cold air current that penetrates the joints, forcing the air mass to circulate through the reflective sheet and weighing the assembly of incandescent resistances and that added to the initial impulsion is projected in a large radius of action, determining by convention currents a rapid heating in the turbulence regime of large cubicles, the assembly of electric thermal regulators and the coupling of protective coverings of the heating device itself, as well as of synchronized automatic switching means at the closing and opening of the doors.
