An ironing installation possessing an ironing machine having two hollow rolls and four heating elements which can be heated by water vapor. During operation water vapor and hot air are sucked into the rolls through holes at the roll shells or jackets. This water vapor-air mixture is expelled to the surroundings through a heat exchanger. Ambient air is sucked into an air infeed line or conduit and infed through the heat exchanger into the internal compartment of a casing which at least partially encloses the rolls and heating elements. Between the aforementioned heat exchanger and an outlet opening or mouth of the air infeed line there is arranged a passage of a second heat exchanger in the air infeed line. A further passage of this second heat exchanger is connected with outlets of the four heating elements.
