Abstract: A heating device having a holding apparatus to accommodate a control unit, the holding apparatus having a receiving part. The receiving part has at least one storage tray for tools and/or at least one receptacle, in particular two receptacles, for tools. A holding apparatus for a heating device is also described.

Abstract: A structural element for a housing structure of a heating device. The structural element is at least essentially, especially completely, developed as a foam part, preferably as a thermoplastic casting foam part. In addition, a housing structure is described, which has a corresponding structural element, preferably at least two corresponding structural elements. Moreover, a heating device is described that includes at least one corresponding structural element and/or a corresponding housing structure. In addition, a method for mounting a corresponding housing structure is described.

Abstract: A heating device having a holding apparatus to accommodate a control unit, the holding apparatus having a receiving part. It is proposed that a cover be fixed in place on the receiving part, which is provided to protect electrical connections or electrical components from a fluid, in particular spray water. A holding apparatus for a heating device is also described.

Abstract: A heating device, in particular a gas-heating system, including a housing structure and an external housing, the external housing having at least one sidewall and at least one cover, which are able to be fixed in place on the housing structure. The at least one cover is developed to position the at least one sidewall in at least one direction in space relative to the housing structure. A method for mounting a heating device is also described.

Abstract: A heating device having a holding apparatus to accommodate a control unit, the holding apparatus having a receiving part. The receiving part has at least two struts, and a receptacle for the control unit is developed between the at least two struts. A holding apparatus for a heating device is also described.

Abstract: A component for connecting a hydraulic unit of a heating device, which includes at least one means for the attachment to a housing structure. The at least one means for the attachment to a housing structure is developed as a plug-in element. A device for connecting a hydraulic unit of a heating device, which includes at least one component for connecting a hydraulic unit of a heating device is also provided. The component is disposed so as to be exchangeable. A heating device, which has at least one hydraulic unit, is also described. The hydraulic unit is fixed in place on a housing structure of the heating device via an exchangeable component. A method for mounting a hydraulic unit of a heating device is also described.
