Abstract: The invention relates to a heating installation for the passenger compartment of omnibuses, comprising radiant heating elements which are disposed on the omnibus side walls under the side windows. In order to accommodate in a space-saving manner the hot-water carrying heating pipes supplying the radiant heating elements with thermal energy, the upper wall surface of the radiant heating elements which faces the passenger compartment is formed by a continuous interior cladding bearer of the respective omnibus side wall and the interior cladding bearer is formed in the armrest region of the passenger seats into a longitudinally continuous arm support. The heating pipe is laid in the cavity formed by this construction.
