Abstract
A vehicle heater includes a burner assembly unit () with a combustion chamber () to be fed with combustion air (V) and fuel (B) and a flame tube (). A heat exchanger assembly unit () includes an inner heat exchanger housing () with an inner circumferential wall () and an outer heat exchanger housing () with an outer circumferential wall (). A heat transfer medium flow space () is between the inner and outer heat exchanger housings, which are elongated in a longitudinal axis (L) direction. A waste gas backflow space (), between the inner circumferential wall () and the flame tube, opens towards an exhaust gas outlet. A catalytic converter device () is provided in the waste gas backflow space associated with an energizable heating unit (), or/and insulation material () is provided on an outer side () facing away from the heat transfer medium flow space.
