Description

Die Erfindung betrifft ein heiz- und wärmetechnisches Gerät gemäß Oberbegriff des Hauptanspruches.The invention relates to a heating and thermal device according to the preamble of the main claim.

Unter heiz- und wärmetechnischen Geräten sind hierbei sowohl Brauchwasserspeicher als auch Heizkessel zu verstehen. Im Prinzip bestehen derartige Geräte aus einem Behälter mit einem Umschließungsgehäuse. Bei einem Brauchwasserspeicher enthält der Behälter das Brauchwasser und bei einem Heizkessel dient der Behälter zur Aufnahme des Heizmediums Wasser und zur Aufnahme der flamm- und gasführenden Räume.Heating and thermal devices are understood to mean both domestic water storage tanks and boilers. In principle, such devices consist of a container with an enclosure. In the case of a domestic hot water tank, the container contains the domestic water and in the case of a boiler, the container serves to hold the heating medium water and to accommodate the flame and gas-bearing rooms.

Brauchwasserspeicher sind bspw. nach den DE-U-19 26 859 und 19 34 770 bekannt, bei denen es sich allerdings um an einer Wand hängend zu installierende Geräte handelt. Andere vorbekannte, in der Regel horizontal aufzustellende Brauchwasserspeicher müssen aufgestellt werden, wofür die Behälter mit Aufstellfüßen oder sonstigen Aufstellelementen (Behältergestellen) versehen sind, die dann gleichzeitig auch als Befestigungselemente für die Umschließungsgehäusebleche dienen, d. h., der konstruktive Aufwand für solche Speicher ist relativ groß. Dies gilt beispielsweise auch für die Brauchwasserspeicher nach den vorerwähnten DE-U-19 26 859 und 1934770, bei denen die Gesamtlast über die seitlichen Gehäusewände in Wandhaken eingeleitet werden muß, was bedeutet, daß die Wandstärke der betreffenden Gehäusewand entsprechend der erwartbaren Biegebeanspruchung ausgelegt sein muß. Derartige Brauchwasserspeicher sind, wie erwähnt, entweder einzeln in Umschließungsgehäusen angeordnet, ggf. in Verbindung mit dem zugehörigen Heizkessel, oder sie weisen Traggestelle auf, an denen dann auch die Einzelbleche des Umschließungsgehäuses befestigt sind. Dies gilt auch für gestapelte Brauchwasserspeicher, die entweder einzeln oder zu mehreren in einem Umschließungsgehäuse angeordnet sind. Ein weiterer Stand der Technik wird durch die LU-A-45662 und die BE-A-418771 repräsentiert.Domestic water storage tanks are known, for example, from DE-U-19 26 859 and 19 34 770, which, however, are devices to be installed on a wall. Other previously known, usually horizontal hot water tanks must be set up, for which the containers are provided with feet or other mounting elements (container frames), which then also serve as fastening elements for the enclosure housing sheets, i. that is, the design effort for such memories is relatively large. This also applies, for example, to the domestic hot water tank according to the aforementioned DE-U-19 26 859 and 1934770, in which the total load has to be introduced into wall hooks via the side housing walls, which means that the wall thickness of the housing wall in question must be designed in accordance with the expected bending stress . Such hot water storage tanks are, as mentioned, either arranged individually in enclosure housings, possibly in connection with the associated boiler, or they have support frames, to which the individual sheets of the enclosure housing are then also attached. This also applies to stacked domestic hot water tanks, which are either arranged individually or in groups in an enclosure. Another prior art is represented by LU-A-45662 and BE-A-418771.

Das gleiche Bauprinzip gilt auch für moderne Heizungskessel, da auch deren wasserführende Gehäuse, sprich Behälter, in dieser bzw. ähnlicher Weise mit ihren Umschließungsgehäusen kombiniert sind.The same construction principle also applies to modern heating boilers, since their water-carrying housings, i.e. containers, are combined in this or a similar way with their enclosure housings.

Der Erfindung liegt demgemäß die Aufgabe zugrunde, heiz- und wärmetechnische Geräte dieser Art dahingehend auszubilden und zu verbessern, daß die Lagerung des Gerätebehälters unter der Voraussetzung bekannter Wärmeabflußverhinderung vom Behälter zum Umschließungsgehäuse erfolgt und dieses unmittelbar die Tragfunktion von sonst üblichen Aufstellelementen übernimmt.The invention is therefore based on the object to design heating and thermal devices of this type in such a way that the storage of the device container is carried out under the assumption of known heat flow prevention from the container to the enclosure and this directly takes over the supporting function of otherwise usual installation elements.

Diese Aufgabe ist mit einem Gerät der eingangs genannten Art der Erfindung durch die im Kennzeichen des Hauptanspruches angeführten Merkmale gelöst. Praktische Ausführungsformen und vorteilhafte Weiterbildungen ergeben sich nach den Unteransprüchen.This object is achieved with a device of the type mentioned in the introduction by the features stated in the characterizing part of the main claim. Practical embodiments and advantageous further developments result from the subclaims.

Wesentlich ist also hierbei, daß die zu den Behälterenden benachbarten Flächen unter Zwischenlage wärmeisolierender Stützringe von den Behälterenden durchgriffen werden und diese Flächen nur in Richtung der Flächenverlaufsebene druckbelastet sind. Dabei ist lediglich ggf. dem Ausbiegemoment Rechnung zu tragen, das natürlich geringer ist, als ein Biegemoment, das wie beim Gegenstand des DE-U-19 26 859 durch eine quer einwirkende Last eingeleitet wird.It is therefore essential here that the surfaces adjacent to the container ends are interspersed with thermally insulating support rings by the container ends and that these surfaces are only subjected to pressure in the direction of the plane of the surface. It is only necessary to take into account the bending moment, which is of course less than a bending moment which, as in the subject of DE-U-19 26 859, is initiated by a transversely acting load.

Da bei der erfindungsgemäßen Lösung ggf. beachtliche Lasten zu berücksichtigen sind, wird im Falle eines Speicherbehälters dieser bevorzugt an beiden Enden mit ringförmigen Kragen versehen, die zur Lastaufnahme besser geeignet sind als relativ durchmesserkleine Anschlußstutzen.Since considerable loads may have to be taken into account in the solution according to the invention, in the case of a storage container, this is preferably provided at both ends with annular collars which are more suitable for load bearing than relatively small connecting pieces.

Bei der erfindungsgemäßen Lösung hängt der Behälter des jeweiligen Gerätes horizontal gewissermaßen frei im Umschließungsgehäuse oder im Gestell, die selbsttragende Elemente für den Behälter sind, wobei aber jeglicher wärmeleitender Direktkontakt zwischen Behälter und Umschließungsgehäuse bzw. -Gestell dieser Forderung folgend, vermieden ist, da an den unvermeidbaren Lagerstellen die aus schlecht wärmeleitendem Material gebildeten Stützelemente sitzen.In the solution according to the invention, the container of the respective device hangs horizontally, as it were, freely in the enclosure housing or in the frame, which are self-supporting elements for the container, but any thermally conductive direct contact between container and enclosure housing or frame is avoided in accordance with this requirement, since the unavoidable bearings the support elements formed from poorly heat-conducting material sit.

Da das Umschließungsgehäuse mit seinen zu den Böden eines Speicherbehälters benachbarten Stirnflächen unmittelbar selbst als Halter für den Behälter ausgenutzt ist, werden lediglich diese nur druckbelasteten Bleche des Umschließungsgehäuses ggf. etwas verstärkt ausgebildet und zwar insbesondere dann, wenn mehrere gestapelte Behälter im Umschließungsgehäuse unterzubringen sind.Since the enclosure housing, with its end faces adjacent to the bottoms of a storage container, is itself directly used as a holder for the container, only these pressure-loaded sheets of the enclosure housing may be designed somewhat reinforced, in particular if several stacked containers are to be accommodated in the enclosure housing.

Auch bei einem als Heizkessel ausgebildeten Gerät ist das Umschließungsgehäuse als tragendes Element in die eigentliche Kesselkonstruktion mit einbezogen und damit zu einem integralen Bauteil des Kessels gemacht, so daß Vorder- und Rückwand eines wasserführenden Heizkesselgehäuses im herkömmlichen Sinne und der damit verbundene Schweiß- und Materialaufwand in Wegfall kommen können. Besondere Sockelanfertigungen, um insbesondere kleine Heizkessel auf geeigneter Höhe installieren zu können, sind ebenfalls entbehrlich, da es ein Einfaches ist, das in die Kesselkonstruktion als Tragelement integrierte Umschließungsgehäuse so in der Blechzuschnittsgröße zu bemessen, daß gleichzeitig ein Aufstellsockel und/oder eine Gehäuseverlängerung nach oben entsteht, bspw. zur Unterbringung eines Speicherbehälters, wobei im Sockelteil des Gehäuses bspw. ein Ausdehnungsgefäß untergebracht werden kann.Even with a device designed as a boiler, the enclosure housing is included as a load-bearing element in the actual boiler construction and thus made an integral component of the boiler, so that the front and rear walls of a water-bearing boiler housing in the conventional sense and the associated welding and material expenditure in Can come away. Special base designs, in particular to be able to install small boilers at a suitable height, are also unnecessary, since it is easy to dimension the enclosure housing integrated in the boiler construction as a supporting element in the sheet metal cut size in such a way that at the same time an installation base and / or a housing extension upwards arises, for example to accommodate a storage container, it being possible for example to accommodate an expansion vessel in the base part of the housing.

Das erfindungsgemäße Gerät, seine praktischen Ausführungsformen und seine vorteilhaften Weiterbildungen werden nachfolgend anhand der zeichnerischen Darstellung von Ausführungsbeispielen näher erläutert.The device according to the invention, its practical embodiments and its advantageous further developments are described below with reference to the drawing of exemplary embodiments play explained in more detail.

Zunächst wird das heiz- und wärmetechnische Gerät in Form eines Speicherbehälters anhand der Fig. 1 bis 3 näher erläutert.First, the heating and thermal device in the form of a storage tank is explained in more detail with reference to FIGS. 1 to 3.

Wie aus Fig. 1 erkennbar, ist der Behälter 3 mit seiner ihn allseitig umschließenden Wärmeisolierung 22 innerhalb des Umschließungsgehäuses 6 angeordnet, das aus entsprechenden Einzeiblechzuschnitten besteht, die an ihren Anschlußrändern (bspw. im Sinne der Fig. 2) angekröpft bzw. für die jeweilige Anschlußabkröpfung passend auslaufend angeordnet sind. Die hierbei interessierenden Einzelzuschnitte aus Blech von etwa 1,6 mm Stärke sind mit 4, 5 bezeichnet. Der hier als Speicherbehälter ausgebildete Behälter 3 hat am Boden 1 einen ringförmigen Kragen 10, innerhalb dessen am Behälter 3 in der Regel eine verschließbare Reinigungsöffnung angeordnet ist (nicht dargestellt). Dieser Kragen 10 kann auch durch einen anderen geeigneten Behälterfortsatz ersetzt sein und je nach zu berücksichtigender Gesamtlast kann auch der andere Boden 2 einen solchen Kragen 10 aufweisen (nicht dargestellt). Beim Ausführungsbeispiel nach Fig. 1 gehen am anderen Boden 2 des Behälters 3 die Vor- und Rücklaufanschlußstutzen 9 ab, die im dargestellten Fall wie der Kragen 10 ebenfalls Tragelemente für den Behälter 3 in bezug auf das Umschließungsgehäuse 6 bzw. dessen Einzelzuschnitte 4, 5 bilden. In den an entsprechenden Stellen angeordneten Öffnungen der Einzelzuschnitte 4, 5, die vorteilhaft mit nach innen gerichteten abgekröpften Rändern 17 versehen sind, sitzen im Durchmesser entsprechend bemessene Stützringe 7, 8 aus schlecht wärmeleitendem Material, die ihrerseits von dem Kragen 10 bzw. den Anschlußstutzen 9 durchgriffen werden. Diese Stützringe 7, 8 aus schlecht wärmeleitendem Kunststoff sind mit konischen Einsteckenden 11, ringförmigen Hinterschneidungsausnehmungen 13 und mit äußeren Flanschen 12 versehen. In Rücksicht auf die Größe des Stützringes 8 und die erforderliche Elastizität zum Aufschnappen auf den abgekröpften Rand 17 ist dieser Stützring 8 mit zwei umlaufenden Ringstegen 18, 19 ausgestattet. Sofern der Behälter 3 eine Reinigungsöffnung (nicht dargestellt) innerhalb des ringförmigen Kragens 10 aufweist, ist gemäß Fig. 1, 2 der Stützring 8 mit einer Kappe 20 abgedeckt. Falls der innere Kragenbereich nicht zugänglich sein muß, bspw. bei Anordnung eines Kragens 10 auch am anderen Boden 2, können natürlich er Stützring 8 und die Abdeckkappe 20 aus einem Teil gebildet sein.As can be seen from Fig. 1, the container 3 with its all-round heat insulation 22 is arranged within the enclosure 6, which consists of corresponding single sheet blanks that are cranked at their connecting edges (for example in the sense of FIG. 2) or for the respective Terminal bend are arranged appropriately tapered. The individual blanks of sheet metal of about 1.6 mm thickness that are of interest here are designated 4, 5. The container 3 embodied here as a storage container has an annular collar 10 on the base 1, within which a closable cleaning opening is generally arranged on the container 3 (not shown). This collar 10 can also be replaced by another suitable container extension and, depending on the total load to be taken into account, the other base 2 can also have such a collar 10 (not shown). In the embodiment according to FIG. 1, the supply and return connection pieces 9 go from the other bottom 2 of the container 3, which in the illustrated case, like the collar 10, also form supporting elements for the container 3 with respect to the enclosure housing 6 or its individual cuts 4, 5 . In the openings of the individual blanks 4, 5 which are arranged at corresponding points and which are advantageously provided with inwardly bent edges 17, there are correspondingly dimensioned support rings 7, 8 made of poorly heat-conducting material, which in turn are supported by the collar 10 or the connecting piece 9 be penetrated. These support rings 7, 8 made of poorly heat-conducting plastic are provided with conical insertion ends 11, annular undercut recesses 13 and with outer flanges 12. In view of the size of the support ring 8 and the required elasticity for snapping onto the bent edge 17, this support ring 8 is equipped with two circumferential ring webs 18, 19. If the container 3 has a cleaning opening (not shown) within the annular collar 10, the support ring 8 is covered with a cap 20 according to FIGS. 1, 2. If the inner collar area does not have to be accessible, for example when a collar 10 is also arranged on the other base 2, the support ring 8 and the cover cap 20 can of course be formed from one part.

Beim Ausführungsbeispiel nach Fig. 3, die das Gerät bei abgenommener Vorderwand des Umschließungsgehäuses zeigt, handelt es sich beim Einzelzuschnitt 4 nicht um eine vordere Fläche des Umschließungsgehäuses im Sinne der Fig. 1 selbst, sondern um eine Gestellplatte 4', die hier zwar für nur einen Speicherbehälter dargestellt ist, die aber insbesondere dann in Frage kommt, wenn bspw. mehrere Speicherbehälter über- und/ oder nebeneinander in einem Umschließungsgehäuse gestapelt angeordnet sind.In the exemplary embodiment according to FIG. 3, which shows the device with the front wall of the enclosing housing removed, the individual blank 4 is not a front surface of the enclosing housing in the sense of FIG. 1 itself, but rather a frame plate 4 ', which is here for only A storage container is shown, but this is particularly suitable if, for example, a plurality of storage containers are stacked one above the other and / or next to one another in an enclosure housing.

Nun folgt anhand der Fig. 4 bis 12 die Erläuterung des Gerätes in Form eines Heizungskessels. Vorausgeschickt sei hierbei, daß die Maßgabe « Ausbildung des wasserführenden Gehäuses in Form eines Rohres nicht zwingend bedeutet, daß das Rohr bzw. Gehäuse zylindrisch sein muß. Die Bezugszeichennumerierung in den Fig. 4 bis 12 beginnt hierbei mit 100 und folgende.4 to 12, the explanation of the device follows in the form of a heating boiler. It should be said here that the requirement that the water-carrying housing be in the form of a tube does not necessarily mean that the tube or housing must be cylindrical. The reference numbering in FIGS. 4 to 12 begins with 100 and the following.

Wie aus Fig. 4, 5 deutlich erkennbar, weist der wasserführende Behälter 100 des Heizkessels keine Vorder- und Rückwand im herkömmlichen Sinne mehr auf, sondern beim Ausführungsbeispiel nach Fig. 4 ist die Außenwand 107 des Behälters 100 an den Enden konisch nach innen gezogen und derart mit dem Innenrohr 106 verbunden, daß die Enden 102 des Innenrohres 106 Auflagekragen 103 bilden, die unter Zwischenlage von wärmeisolierendem Material in Form von Stützringen 109 auf den Auflagerändern 108 der Öffnung 104 des Umschließungsgehäuses 105 direkt gelagert sind (siehe hierzu auch Fig. 9, aus der auch ersichtlich ist, daß für das Material des Stützringes 109 zweckmäßig ein entsprechend abgelängtes Stück eines Endlosprofiles verwendet werden kann.As can be clearly seen from FIGS. 4, 5, the water-carrying container 100 of the boiler no longer has a front and rear wall in the conventional sense, but in the exemplary embodiment according to FIG. 4, the outer wall 107 of the container 100 is drawn conically inwards at the ends and connected to the inner tube 106 in such a way that the ends 102 of the inner tube 106 form support collars 103 which, with the interposition of heat-insulating material in the form of support rings 109, are mounted directly on the support edges 108 of the opening 104 of the enclosing housing 105 (see also FIG. 9, from which it can also be seen that a correspondingly cut-to-length piece of an endless profile can expediently be used for the material of the support ring 109.

Bei der Ausführungsform nach Fig. 5, die nur das wasserführende Gehäuse eines Heizkessels zeigt, bildet die Außenwand 107 die Auflagekragen 103', und das Innenrohr 106 ist, wie dargestellt, konisch erweitert in das Außenrohr entsprechend eingesetzt und mit diesem verschweißt. Wie erkennbar, ist damit der Wärmefluß aus dem Innenrohr 106 zum Auflagekragen nicht so direkt, wie dies bei Fig. 4 der Fall ist. Da sich aber dadurch gasseitig liegende Schweißnähte ergeben, wird jedoch die Ausführungsform nach Fig. 4, 9 bevorzugt. Da das Umschließungsgehäuse 105 eine Tragfunktion zu übernehmen hat, könnte man natürlich die Bauprinzipien bisheriger Gehäuse beibehalten, d. h. für tragende Teile größere Blechstärken vorsehen. Vorteilhafter ist jedoch die Ausführungsform des Umschließungsgehäuses im Sinne der Fig. 6, gemäß der das Gehäuse 105 aus zwei in Draufsicht U-förmig gekröpften Blechzuschnitten 105' gebildet ist, die in sich wieder mit geeigneten Versteifungsprägungen 110 und Versteifungsabkantungen 110' (insbesondere in den Verbindungsbereichen) versehen sind, wodurch ohne weiteres eine ausreichende Tragfähigkeit des Umschließungsgehäuses 105 auch bei Verwendung bisher üblicher Blechstärken gewährleistet ist und zwar insbesondere dann, wenn es sich um Klein-Heizkessel handelt, die « en bloc », wie in Fig. 4 und 12 dargestellt, geliefert werden können.In the embodiment according to FIG. 5, which only shows the water-carrying housing of a boiler, the outer wall 107 forms the support collar 103 ', and the inner tube 106 is, as shown, inserted conically expanded into the outer tube and welded to it. As can be seen, the heat flow from the inner tube 106 to the support collar is not as direct as is the case in FIG. 4. However, since this results in weld seams on the gas side, the embodiment according to FIGS. 4, 9 is preferred. Since the enclosing housing 105 has to take on a supporting function, one could of course maintain the construction principles of previous housings, ie provide larger sheet metal thicknesses for supporting parts. However, the embodiment of the enclosing housing in the sense of FIG. 6, according to which the Housing 105 is formed from two sheet metal blanks 105 'which are U-shaped in a plan view and which are in turn provided with suitable stiffening embossments 110 and stiffening folds 110' (in particular in the connection areas), which means that the housing 105 has a sufficient load-bearing capacity, even when previously used usual sheet thicknesses is guaranteed, especially when it comes to small boilers that can be supplied "en bloc", as shown in FIGS. 4 and 12.

Wenn es sich, wie gesagt, um relativ kleine Heizkessel handelt, die also bisher auf separat gefertigten Blechsockeln installiert wurden, so ist es natürlich absolut problemlos, die in Fig. 6 dargestellten Blechzuschnitte im Sinne der Fig. 4 bezgl. der Höhe größer zuzuschneiden, so daß das Umschließungsgehäuse auch gleichzeitig den Kesselaufstellsockel 105" mitbildet, in dessen Freiraum bspw. ein Ausdehnungsgefäß 120 untergebracht werden kann.If, as I said, the boilers are relatively small and have so far been installed on separately manufactured sheet metal bases, it is of course absolutely no problem to cut the sheet metal cuts shown in FIG. 6 larger in terms of FIG. 4 with respect to the height. so that the enclosure housing also forms the boiler mounting base 105 ", in the free space of which, for example, an expansion vessel 120 can be accommodated.

Die Verbindung der beiden Blechzuschnitte 105', unabhängig davon wie groß diese in der Höhe bemessen sind, kann gemäß Fig. 7, 8 auf verschiedene Weise erfolgen, wobei jedoch auch hier eine Ausbildung im Sinne einer Aussteifung vorgesehen ist.The connection of the two sheet metal blanks 105 ', regardless of how large they are in terms of height, can take place in different ways according to FIGS. 7, 8, but here, too, training in the sense of stiffening is provided.

Bei der Ausführungsform gemäß Fig. 7 ist der eine Rand mit einer rechtwinkligen Abkröpfung 113 und der andere mit einer Nutabkröpfung 114, dargestellt, versehen, und beide Ränder 113', 114' bzw. Anlageflächen sind bspw. durch Vernietung fest miteinander verbunden, wobei die Abkröpfung 113 in die Nutabkröpfung 114 eingreift und an die benachbarte Wand der Nutabkröpfung 114 direkt angelegt ist. Bei der Ausführungsform nach Fig. 8 sind beide Ränder in gleicher Form mit U-förmigen Abkantungen 115 versehen und durch eine beide Abkantungen erfassendes Klemmprofil 116, das aus Kunststoff bestehen kann, lösbar verbunden.In the embodiment according to FIG. 7, one edge is provided with a right-angled offset 113 and the other with a groove offset 114, and both edges 113 ', 114' or contact surfaces are connected to one another, for example by riveting, the Bend 113 engages in the groove bend 114 and is applied directly to the adjacent wall of the groove bend 114. In the embodiment according to FIG. 8, both edges are provided in the same shape with U-shaped bevels 115 and are detachably connected by a clamping profile 116 which detects both bevels and which can be made of plastic.

Da die ganze Gerätekonstruktion in diesem Falle besonders dafür geeignet und angelegt ist, das komplette Gerät bzw. Heizkessel fix und fertig ausliefern zu können, ist das Umschließungsgehäuse bodenseitig in den durch Versteifungsprägungen 110 versteiften Ecken 117 mit Eckstützprofilen 118 bspw. aus Kunststoff versehen, die mit Blindnieten 118' rundum am Blech fixiert sind und die Fußschrauben 119 aufweisen', womit vorteilhaft einerseits eine Möglichkeit zur Einnivellierung des ganzen Heizungskessels gegeben ist, andererseits aber auch eine einfachere Befestigungsmöglichkeit auf Transportpaletten. Außerdem haben solche Eckstützprofile 118 eine Dämpfungswirkung gegen den Aufstellboden.Since in this case the entire device construction is particularly suitable and designed to be able to deliver the complete device or boiler ready and ready, the enclosure housing is provided with corner support profiles 118, e.g. made of plastic, in the corners 117 stiffened by stiffening embossments 110 Blind rivets 118 'are fixed all around on the sheet metal and have the foot screws 119', which on the one hand advantageously provides a possibility for leveling the entire heating boiler, but on the other hand also makes it easier to attach it to transport pallets. In addition, such corner support profiles 118 have a damping effect against the floor.

Genauso wie das Umschließungsgehäuse 105 als integrales Bauteil der ganzen Heizkesselkonstruktion nach unten zur Sockelausbildung verlängert werden kann, ist auch, wie aus Fig. 12 erkennbar, eine entsprechende Verlängerung nach oben möglich, um Raum für die Unterbringung eines vertikal angeordneten Speicherbehälters 112 zu schaffen, der mit seinen Bodenkragen als Tragsteg 111 direkt auf das wasserführende Gehäuse 101 aufgesetzt ist und mit seinem oberen Kragen 111' (siehe auch Fig. 11) als Haltekragen 103" in einem Durchgriff des Umschließungsgehäuses 105 bzw. dessen Deckblech 105"' in einem wärmeisolierenden Profilring 121 gehalten ist.Just as the enclosure 105 can be extended downwards as an integral component of the entire boiler construction to form a base, as can be seen in FIG. 12, a corresponding extension upwards is also possible in order to create space for accommodating a vertically arranged storage container 112 which with its bottom collar as support web 111 is placed directly on the water-carrying housing 101 and with its upper collar 111 '(see also FIG. 11) as a holding collar 103 "in a passage of the enclosing housing 105 or its cover plate 105"' in a heat-insulating profile ring 121 is held.

Nur der Vollständigkeit halber sei erwähnt, daß an den Vor- und Rücklaufanschlüssen 122, 123 Verteiler 124 angeschlossen sind für den Anschluß von Heizkreisen, wobei am Rücklauf 123 auch das Ausdehnungsgefäß 120 hängt. 125 ist der Kaltwasserzulauf und 126 der Warmwasservorlauf des Speicherbehälters 112, dessen nicht dargestellter Wärmetauscher über Leitungen 127 mit dem wasserführenden Innenraum des Gehäuses 101 verbunden ist.For the sake of completeness, it should be mentioned that distributors 124 are connected to the supply and return connections 122, 123 for the connection of heating circuits, the expansion vessel 120 also being attached to the return 123. 125 is the cold water inlet and 126 is the hot water flow of the storage tank 112, the heat exchanger (not shown) of which is connected via lines 127 to the water-carrying interior of the housing 101.
