Beschreibung [0001] Die Erfindung bezieht sich auf ein Abgasrohr für ein brennstoffbeheiztes Heizgerät, an welches ein Solarabsorber angeschlossen ist.Description: [0001] The invention relates to an exhaust pipe for a fuel-fired heater to which a solar absorber is connected.

[0002] Brennstoffbeheizte Heizgeräte verfügen über ein Abgasrohr, über welches die Verbrennungsabgase in die Umgebung geleitet werden. Häufig werden koaxiale Abgasrohre eingesetzt. Bei diesen befindet sich im Inneren eine Abgasleitung, um die koaxial eine Frischluftleitung angeordnet ist. Bei einem koaxialen Abgasrohr kann Restwärme des Abgases auf die zum Heizgerät strömende Frischluft übertragen werden, wodurch der Wirkungsgrad erhöht wird.Fuel-fired heaters have an exhaust pipe through which the combustion exhaust gases are conducted into the environment. Often coaxial exhaust pipes are used. In these is located inside an exhaust pipe to which coaxially a fresh air line is arranged. In a coaxial exhaust pipe residual heat of the exhaust gas can be transmitted to the fresh air flowing to the heater, whereby the efficiency is increased.

[0003] Brennstoffbeheizte Heizgeräte werden häufig mit Solarabsorbern zur Brauch- und/oder Heizwassererwärmung kombiniert. In einem Solarabsorber wird Wasser oder ein Wasser-Glykol-Gemisch erhitzt. Das erhitzte Fluid wird zumeist entweder direkt in einen Warmwasserspeicher geleitet oder in dem brennstoffbeheizten Heizgerät auf die Solltemperatur weiter erwärmt. Der Solarabsorber und das brennstoffbeheizte Heizgerät müssen hierbei über eine solare Vorlauf- und Rücklaufleitung miteinander verbunden werden. Da Solarabsorber häufig nachgerüstet werden, sind zur Verlegung der Vorlauf- und Rücklaufleitungen zum Solarabsorber aufwändige Bauarbeiten nötig.Fuel-fired heaters are often combined with solar absorbers for domestic and / or Heizwassererwärmung. In a solar absorber, water or a water-glycol mixture is heated. The heated fluid is usually either passed directly into a hot water tank or further heated in the fuel-fired heater to the target temperature. The solar absorber and the fuel-heated heater must be connected to each other via a solar flow and return line. As solar absorbers are often retrofitted, complex construction work is required to lay the supply and return lines to the solar absorber.

[0004] Aufgabe der vorliegenden Erfindung ist daher, ein installationsfreundliches Leitungssystem für ein brennstoffbetriebenes Heizgerät mit Abgasrohr und Anschluss an einen Solarabsorber zu ermöglichen.Object of the present invention is therefore to enable an installation-friendly piping system for a fuel-fired heater with exhaust pipe and connection to a solar absorber.

[0005] Erfindungsgemäß wird dies gemäß den Merkmalen des Anspruchs 1 dadurch gelöst, dass ein Abgasrohr für ein brennstoffbeheiztes Heizgerät über eine umgebende Wärmedämmung, in der die Vor- und Rücklaufrohre zum Anschluss eines Solarabsorbers verlaufen, verfügt.This is achieved according to the features of claim 1, characterized in that an exhaust pipe for a fuel-fired heater via a surrounding heat insulation, in which the supply and return pipes for connecting a solar absorber, has.

[0006] Die Unteransprüche schützen vorteilhafte Ausgestaltungen der Erfindung. So kann in der Wärmedämmung zusätzlich eine Leitung zum Anschluss eines Kollektorfühlers verlaufen. Bei dem Abgasrohr kann es sich um ein koaxiales Abgasrohr mit Abgas- und Luftführung handeln. Das Abgasrohr kann aus mehreren miteinander verbindbaren Teilstücken bestehen, wobei optional die Abgas- und ggf. Luftführungsteile konisch verlaufen, die Vor- und Rücklaufrohre verschraub- oder lötbar sind und die Leitung zum Anschluss eines Kollektorfühlers steckbar ist.The dependent claims protect advantageous embodiments of the invention. Thus, in the thermal insulation additionally run a line for connecting a collector sensor. The exhaust pipe may be a coaxial exhaust pipe with exhaust and air ducts. The exhaust pipe may consist of several connectable sections, optionally the exhaust and possibly air guide parts are conical, the supply and return pipes are screwed or soldered and the line for connecting a collector sensor is pluggable.

[0007] Die Erfindung wird nun anhand der Figuren detailliert erläutert. Hierbei zeigen [0008] Fig. 1 ein erfindungsgemäßes Abgasrohr mit einer asymmetrischen Anordnung der Wärmedämmung, [0009] Fig. 2 ein Abgasrohr mit symmetrischer Anordnung der Wärmedämmung, [0010] Fig. 3 ein koaxiales Abgasrohr mit asymmetrischer Wärmedämmung und Fig. 4 ein koaxiales Abgasrohr mit symmetrischer Wärmedämmung.The invention will now be explained in detail with reference to FIGS. 1 shows an inventive exhaust pipe with an asymmetrical arrangement of the thermal insulation, FIG. 2 shows an exhaust pipe with a symmetrical arrangement of the thermal insulation, FIG. 3 shows a coaxial exhaust pipe with asymmetric thermal insulation and FIG. 4 shows a coaxial one Exhaust pipe with symmetrical thermal insulation.

[0011] Figur 1 zeigt ein Abgasrohr 1 für ein nicht dargestelltes brennstoffbeheiztes Heizgerät mit umgebender Wärmedämmung 2. In der Wärmedämmung 2 befindet sich ein Vorlauf- 3 und Rücklaufrohr 4 zum Anschluss eines nicht dargestellten Solarabsorbers. Ferner befindet sich in der Wärmedämmung 2 eine Leitung 5 zum Anschluss eines nicht dargestellten Kollektorfühlers. Die Wärmedämmung 2 ist asymmetrisch um die Abgasführung 6 angeordnet, so dass die Rohre 3,4,5 in der Wärmedämmung relativ dick umschlossen sind.Figure 1 shows an exhaust pipe 1 for a not shown fuel-fired heater with surrounding heat insulation 2. In the insulation 2 is a flow 3 and return pipe 4 for connection of a solar absorber, not shown. Furthermore, located in the insulation 2, a line 5 for connecting a collector sensor, not shown. The thermal insulation 2 is arranged asymmetrically around the exhaust gas guide 6, so that the pipes 3,4,5 are enclosed in the thermal insulation relatively thick.

[0012] Figur 2 zeigt ein Abgasrohr 1 mit symmetrischer Wärmedämmung 2. Hierdurch ergibt sich im Vergleich zu Figur 1 der Unterschied, dass die Rohre 3, 4, 5 nur relativ dünn von Dämmung 2 umgeben sind.Figure 2 shows an exhaust pipe 1 with symmetrical thermal insulation 2. This results in comparison to Figure 1, the difference that the tubes 3, 4, 5 are surrounded only relatively thin insulation 2.

[0013] Figur 3 zeigt ein koaxiales Abgasrohr 1 mit Abgas- 6 und Luftführung 7. Die Rohre 3, 4, 5 befinden sich im dicken Teil der asymmetrischen Wärmedämmung 2.Figure 3 shows a coaxial exhaust pipe 1 with exhaust 6 and air duct 7. The tubes 3, 4, 5 are located in the thick part of the asymmetric thermal insulation. 2
