Abstract

A vehicle heater includes a heater housing (12) elongated in a direction of a housing longitudinal axis (L). A housing circumferential wall (34) defines a combustion air flow space (40). A combustion chamber assembly unit (14) is carried on the heater housing and has a combustion chamber (20) receiving combustion air from the combustion air flow space. A combustion air blower (42), with a combustion air blower housing (44), is carried on the heater housing. A combustion air inlet opening (56), in the combustion air blower housing, provides the inlet for combustion air into the combustion air blower. A combustion air connection unit (64), carried on the heater housing, has a combustion air passage duct (74) open outwardly in a first duct opening area (76) for receiving combustion air. The combustion air passage duct is open towards the combustion air inlet opening in a second duct opening area (78).
