A vehicle heater includes a burner arrangement (12) with a flame tube (16), a heat exchanger housing (18) with a circumferential wall (20), which surrounds the flame tube and thus defines a waste gas backflow space (26) and has a waste gas outlet (38) from the waste gas backflow space. A flow cross section provided between the flame tube and the circumferential wall in a first axial area (33) of the waste gas backflow space is smaller in an outlet area (48) than in an opposite area (50) located opposite the outlet and the flow cross section in the outlet area increases in an expansion area following the first axial area. The flow cross section in a second axial area (35) following the expansion area (52), corresponds essentially to the flow cross section in the opposite area and/or the flow cross section has a stepped increase in the expansion area.
