Catalytic hot-air generator, in particular for closed rooms, comprising at least one catalytic plate, an exchanger consisting of manifolds and pipelines, comprising a fin group with extended heat exchange wall, characterised in that the said catalytic plate 12 is situated inside a combustion chamber 13 into which the surrounding air is sucked to produce the combustion, the hot combustion products which are formed undergo forced circulation under the action of first suction means 19 inside the manifolds and the tubes of the said heat exchanger 15, and being expelled outside the room, second suction means 22 also being provided to take in the surrounding air, pass it into the fin assembly, inside a pipe made in the combustion chamber and to return it hot into the room itself. <IMAGE>
