  • the invention relates to a heating system for a building, a heater for the heating system and a connection element for the heating system.
  • connection elements exhaust adapters
  • connection elements should be able to be used. Nevertheless, these connection elements should be as easy and/or compact as possible to produce and as easy as possible to install or assemble.
  • a heating system for a building contributes to this, the heating system comprising a heater and an exhaust gas supply air pipe system, the exhaust gas supply air pipe system being connectable or connected to the heater (flow-wise) by means of a (common) connection element, the Connection element is mechanically connected or connected by means of a bayonet connection with the heater and the bayonet connection comprises a locking element arrangement, by means of which after closing the bayonet connection by a predeterminable angle of rotation opening the bayonet connection (releasably) can be blocked.
  • the heating system is generally used to heat a building, such as a residential building, and/or in particular to heat a water supply, such as a water circuit in the residential building.
  • the heater is usually a gas heater.
  • this relates in particular to a heater which is set up to burn one or more gases, possibly with the supply of ambient air from a building, in order to generate energy for heating water, for example, for use in an apartment.
  • the heater can be a so-called gas condensing boiler.
  • the heater usually exhibits at least one burner (with a combustion chamber) and a conveying device such as a fan, which conveys a mixture of fuel (gas) and combustion air (through a mixture duct of the heater) to the burner.
  • the exhaust-air supply pipe system usually includes an exhaust pipe and an air supply pipe.
  • the exhaust gas pipe can be guided at least in sections (coaxially) in the air intake pipe.
  • the exhaust pipe is used to remove exhaust gases from the heater.
  • the supply air pipe serves to supply ambient air to the heater in order to function as combustion air in the heater.
  • connection element can be formed, for example, in the form of an adapter.
  • connection element can represent, for example, an exhaust gas adapter or exhaust gas supply air adapter.
  • the bayonet connection can be configured or designed in such a way that only specific connection elements, for example only connection elements approved for the heater, can be connected to the heater.
  • a heater-typical or heater-type-specific bayonet connection element can be formed on the heater.
  • a (only) corresponding bayonet connection element can be formed on the connection element.
  • the bayonet connection can be distinguished, for example, by a locking element arrangement, by means of which, after the bayonet connection has been closed by a predeterminable angle of rotation, opening of the bayonet connection can be blocked.
  • a heater-side bayonet connection element of the bayonet connection for example, a heater-side latching element of the latching element arrangement can be provided.
  • a bayonet connection element of the bayonet connection on the connection element side for example, a latching element on the connection element side of the latching element arrangement can be provided.
  • the latching element on the heating device side and the latching element on the connecting element side are generally formed to correspond to one another.
  • the locking element on the heater side and/or the shape or contour of the bayonet connection element on the heater side can be formed or shaped in the area of the locking element on the heater side in such a way that only those connection elements can be (safely) connected to the heater that have a bayonet connection element on the connection element side with the bayonet connection element on the connection element side Have locking element of the locking elements arrangement.
  • the predeterminable angle of rotation can also contribute to the characterization of the bayonet connection.
  • the angle of twist can be predetermined to a value in the range from 5° to 15°.
  • the angle of twist can be predetermined at approximately 10°.
  • the locking element arrangement comprises a ramp element and a locking lug element.
  • the ramp element can form the locking element on the heater side and the locking nose element can form the locking element on the connection element side.
  • the ramp element is arranged and aligned in such a way that its ramp has a slope in the circumferential direction.
  • At least one latching element of the latching element arrangement can be deflected or disengaged relative to another latching element of the latching element arrangement.
  • the detent element in the radial direction
  • a (separate) tool may be required, for example, which can reach the locking element arrangement, for example, through a dismantling opening of the connection element.
  • At least one section of the exhaust gas supply air pipe system can be mechanically connected or is connected to the connection element by means of at least one fixing element.
  • the section of the exhaust gas supply air pipe system can relate to a lower end of the supply air pipe, for example.
  • the at least one fixing element comprises a fixing element that acts in a form-fitting manner.
  • the positively acting fixing element can, for example, be set up and/or arranged in such a way or (in the assembled state) arranged in such a way that it secures the exhaust gas supply air pipe system axially with respect to the connecting element. In other words, this can also be described in particular in such a way that the positively acting fixing element can prevent the exhaust gas supply air pipe system from axially loosening or slipping out of the connection element (along the central axis of the connection element).
  • the positively acting fixing element can be formed in the manner of a clip or be a clip.
  • the positively acting fixing element can be a pin-shaped clip. Exactly one fixing element that acts in a form-fitting manner is preferably provided.
  • the at least one fixing element comprises a fixing element that acts in a non-positive manner.
  • the non-positively acting fixing element can, for example, be set up and/or arranged in such a way or (in the assembled state) arranged in such a way that it prevents unwanted twisting or an unwanted rotary movement of the exhaust gas supply air pipe system (about the central axis of the connecting element) relative to the connecting element or can prevent in the connection element.
  • the non-positively acting fixing element can be a screw.
  • Two non-positively acting fixing elements are preferably provided.
  • the connecting element be formed at least in sections in the shape of a ring around a central axis and a longitudinal axis of the at least one fixing element in the connected state encloses an angle in the range of 45° to 90° with the central axis.
  • This can advantageously contribute to the connection element being able to be as compact as possible, in particular comparatively flat.
  • the angle is preferably in the range from 60° to 90°, particularly preferably in the range from 75° to 98°. If several fixing elements are provided, it is also preferred if the longitudinal axes of all fixing elements enclose an angle in the range of 45° to 90° (or an angle according to one of the more preferred ranges mentioned) with the central axis.
  • At least one measuring opening for inserting a measuring probe into the exhaust gas supply air pipe system is formed on the outside of the connection element.
  • Two measurement openings, in particular an exhaust gas measurement opening and an inlet air measurement opening, are preferably formed externally to the connection element.
  • the at least one measuring opening can, for example, be integrated into the exhaust gas supply air pipe system or formed thereon. This can contribute to the fact that no measurement opening has to be realized in or on the connection element, so that the connection element can advantageously be designed as compactly as possible.
  • connection element be formed in the shape of a plate.
  • connection element can have an extension along the central axis of at most 10 cm [centimeters]. This can also contribute to the connection element being able to be designed as compactly as possible.
