Vehicle heater

A vehicle heater comprising:

• a heater housing through which heating air to be heated can flow and which heater housing extends in a direction of a housing longitudinal axis, the heater housing having a heating air inlet area and a heating air outlet area;
• a burner unit arranged in the heater housing;
• a combustion air blower arranged in the heater housing for delivering combustion air to the burner unit;
• a heat exchanger unit arranged in the heater housing and around which heating air flowing through the heater housing can flow;
• and
• a combustion air intake muffler arranged essentially in the heater housing and associated with the combustion air blower, wherein a muffler housing is made in one piece with at least a portion of the heater housing, wherein the combustion air blower comprises:
• a blower body with a delivery duct, which has a ring-shaped extent about an axis of rotation and which is open in a first axial direction on a first axial side of the blower body;
• a combustion air delivery wheel located opposite the blower body on the first axial side thereof with a ring-shaped delivery area covering the delivery duct and with a plurality of delivery blades following each other about the axis of rotation in a circumferential direction;
• a blower motor arranged on a second axial side of the blower body, which second axial side is opposite the first axial side of the blower body, with a motor shaft rotatable about the axis of rotation, wherein the motor shaft is coupled with the combustion air delivery wheel for joint rotation about the axis of rotation;
• and
• a delivery duct inlet area open to the delivery duct in the blower body for the entry of combustion air into the delivery duct, wherein the combustion air intake muffler is arranged essentially on the second axial side of the blower body, wherein the combustion air intake muffler comprises:
• a first muffler flow path guiding combustion air from a combustion air inlet area of the combustion air blower in a first axial direction;
• a second muffler flow path guiding combustion air in a second axial direction toward a delivery duct inlet area of the combustion air blower, the second axial direction being opposite the first axial direction, wherein the first muffler flow path and the second muffler flow path extend parallel to an axis of rotation of a combustion air delivery wheel of the combustion air blower.
