Abstract
Electro-impeller of double use, of the type comprising a conventional fan support of blades protected by a grid that is characterized in that said grid serves as a support, with removable character, to another carrier grid in its interior of a refractory plate and insulator provided with a through groove that covers most of its. The surface, in which an electrical resistance is mounted, mounted by supports that keep it practically in the air, deforms that the jet of air driven by the fan rubs against the resistance yielding a part of heat that is driven by convection.
