1. A heating device for a vehicle, comprising:

  • a flow path for a liquid heat transport medium;

    an electric heating unit generating heat; and

    a heat transfer unit discharging generated heat from the electric heating unit to the heat transport medium in a heating section of the flow path; and

    a first electronic control unit controlling the electric heating unit, the control unit including a heat discharge body discharging waste heat from the control unit to the heat transport medium in a preheating section of the flow path upstream of the heating section, wherein the heat transfer unit and the heat discharge body are formed in a single-piece unitary construction, the single piece unitary construction including a non-linear thermal decoupling portion extending between the heat transfer unit and the heat discharge body and increasing the thermal resistance between the heat transfer unit—

    and the heat discharge body as compared to a straight line.
