A heated flooring module is provided for livestock stables, which includes an upper plaque, for walking on, which is essentially level; a hollowed central section, with no bottom surface, whose upper surface is equipped with at least one continuous runnel, adapted to contain a heat source that enters and exits the runnel through respective entry and exit tubular segments, with the abovementioned hollowed central section equipped with suspension elements for being suspended from resistant elements such as the bars of a horizontal grid; and an optional under-lid, all of the above arranged in such a way that, when the upper plaque is welded to the upper surface of the hollowed central section, the continuous runnel forms an enclosed circuit which contains the heat source inside, leaving the under-lid fitted into the underside of the hollowed central section.
