Abstract:
1. A heating device for a vehicle, comprising: a burner means for producing combustion heat, a heat exchanger means for transferring combustion heat produced in the burner means to medium to be heated, wherein the heat exchanger means has a first heat exchanger region for transferring combustion heat to a gaseous first medium to be heated and a second heat exchange region for transferring combustion heat to a liquid second medium to be heated, wherein the heat exchanger means has a heat exchanger body with a combustion exhaust gas conducting space provided therein and surrounded by the heat exchanger body for receiving combustion heat from the combustion exhaust gases flowing through the combustion exhaust gas conducting space, wherein furthermore the first heat exchanger region has numerous heat transfer ribs provided on the outside of the heat exchanger body and respectively providing heat transfer surfaces, and the second heat exchanger region has a flow duct means for the second medium to be heated, the flow duct means includes at least one medium conducting duct running in the region of the heat transfer ribs, and wherein the at least one medium conducting duct passes at least partially through at least a portion of the heat transfer ribs.
