<p>A device for heating the ambient air or, by means of heat exchangers, increase the temperature of fluids and solids for home and industrial use, consisting in housing 3 for filament lamps 4 being insulated and transparent, in which the fan or aspirator 2 determins the forced circulation of the air, taken by means of hollow tube 1 nearby the ceiling of the ambients, around said lamps 4, with thermal exchange and consequent increase of the temperature and final emission of the heated fluid into the ambient. The same heat source, consisting in filament lamps, provides at the same time for the lighting with considerable energetic savings.</p> |
