The present invention concerns a heating device for motor vehicles comprising a heat exchanger with primary and secondary circuits. The said exchanger is connected, through a system of ducts to the passenger compartment of the vehicle and/or to the front and/or the rear windows of the same. The said device is intended to heat the said passenger compartment and/or to de-ice the said front and/or rear windows. Under the invention, the said heat exchanger (3) is placed at the engine (M) exhaust of the said vehicle (1). The exchanger (3) primary circuit (12) is on the one hand, connected to the outlet of any cylinders (C) of the engine (M) so as to be crossed by the exhaust gases from the latter and, on the other hand, it is connected to the manifold (13) leading to the muffler.
