Description

Die Erfindung betrifft eine Baueinheit für eine Heizungsanlage mit zwei Heizkreisen gemäß den im Oberbegriff des Anspruchs 1 angegebenen Merkmalen.The invention relates to a structural unit for a heating system with two heating circuits according to the features indicated in the preamble of claim 1.

Derartige Baueinheiten zählen zum Stand der Technik und werden typischerweise in so genannten Gasthermen eingesetzt, die zur Wandmontage vorgesehen sind, aber auch in Standgeräten. Diese kompakt ausgebildeten Geräte weisen einen Primärwärmetauscher auf, in welchem im Kreislauf geführtes Wasser erwärmt wird, das entweder einem für die Raumheizung vorgesehenen Heizkreis oder aber einem Wärmetauscher, typischerweise einem Plattenwärmetauscher zugeführt wird, über den die Brauchwassererwärmung erfolgt. Die Baueinheit umfasst dabei typischerweise mehrere aus Kunststoff bestehende Gehäusebauteile, mindestens ein Pumpenaggregat, einen Wärmetauscher für die Brauchwassererwärmung und weitgehend auch alle sonstigen elektrischen, mechanischen und/oder hydraulischen Komponenten soweit sie in der Baueinheit sinnvoll zusammengeführt werden können. Dies sind typischerweise Filter, Schmutz-Luftabscheider, Schaltventile, Drosselventile, Temperatur- und Drucksensoren und dergleichen.Such units are state of the art and are typically used in so-called gas heaters, which are intended for wall mounting, but also in stationary units. These compact devices have a primary heat exchanger in which circulated water is heated, which is supplied either to a heating circuit provided for space heating or a heat exchanger, typically a plate heat exchanger, via which the domestic water heating takes place. The assembly typically includes a plurality of housing components made of plastic, at least one pump unit, a heat exchanger for domestic water heating and largely all other electrical, mechanical and / or hydraulic components as far as they can be meaningfully combined in the unit. These are typically filters, dirt-air separators, switching valves, throttle valves, temperature and pressure sensors and the like.

Eine solche Baueinheit, bei welcher drei Gehäusebauteile unter Eingliederung des Pumpenaggregats aneinander anschließen und rückseitig durch den Wärmetauscher verbunden sind, ist aus EP 1 528 330 A1 bekannt. Diese Baueinheit ist hochintegriert und besteht im Wesentlichen aus drei Gehäusebauteilen, nämlich einem zentralen Pumpengehäusebauteil und zwei seitlich daran angrenzenden Armaturengehäusebauteilen.Such a unit in which connect three housing components with inclusion of the pump unit together and are back connected by the heat exchanger, is off EP 1 528 330 A1 known. This unit is highly integrated and consists essentially of three housing components, namely a central pump housing component and two laterally adjacent fitting housing components.

Diese hochintegrierte Baueinheit hat sich in der Praxis bestens bewährt, allerdings kann es nachteilig sein, dass die verwendeten Kunststoffe nur sehr begrenzt an die hydraulischen Anforderungen angepasst werden können.This highly integrated unit has proven itself in practice, but it may be disadvantageous that the plastics used can be adapted only very limited to the hydraulic requirements.

Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, eine gattungsgemäße Baueinheit so auszubilden, dass eine möglichst optimale Werkstoffanpassung an die darin geführten Flüssigkeiten und deren Drücke einerseits und eine kostengünstige Herstellung andererseits gewährleistet sind.Against this background, the invention has the object, a generic unit in such a way that the best possible material adaptation to the liquids guided therein and their pressures on the one hand and cost-effective production on the other hand are guaranteed.

Diese Aufgabe wird gemäß der Erfindung durch die in Anspruch 1 aufgeführten Merkmale gelöst. Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen, der nachfolgenden Beschreibung und der Zeichnung.This object is achieved according to the invention by the features listed in claim 1. Advantageous embodiments of the invention will become apparent from the dependent claims, the following description and the drawings.

Die erfindungsgemäße Baueinheit, welche für eine Heizungsanlage mit zwei Heizkreisen, einen für die Raumheizung und einen für die Warmwasserbereitung, vorgesehen ist, weist mindestens ein aus Kunststoff bestehendes Gehäusebauteil, ein Pumpenaggregat und einen Wärmetauscher für die Brauchwassererwärmung sowie weitere elektrische, mechanische und/oder hydraulische Komponenten auf. Gemäß der Erfindung ist die Baueinheit so ausgebildet, dass vier Gehäusebauteile vorgesehen sind, die jeweils eine Leitungsführung zum Wärmetauscher bilden. Diese erfindungsgemäße Lösung ermöglicht es, die Gehäusebauteile, die an den Wärmeantauscher anschließen, hinsichtlich ihres Werkstoffs so auszulegen, dass sie an den Einsatzzweck möglichst gut angepasst sind. So sind die Leitungsführungen für das Heizungswasser, das also auch durch den Primärwärmetauscher und durch die Heizkörper für die Raumheizung strömt, bevorzugt aus einem Kunststoff gefertigt oder mit einer Beschichtung versehen, die eine besonders harte Oberfläche aufweist, so dass einerseits mit der Förderflüssigkeit mitgeführte Partikel keinen abrasiven Einfluss auf die Leitungswandung ausüben können, andererseits sich auch in diesem Bereich keine Ablagerungen bilden. Die Gehäusebauteile, die an den Wärmetauscher anschließen und das kalte bzw. das erwärmte Brauchwasser führen, können durch die erfindungsgemäße Ausbildung werkstoffmäßig so ausgelegt werden, dass sie gegen im Wasser gegebenenfalls vorhandene Zusatzstoffe wie Chlor, Fluor und dergleichen unempfindlich sind und darüber hinaus auch keine Stoffe abgeben, die damit in das Trinkwasser gelangen könnten. Zwar wird durch die erfindungsgemäße Lösung die Anzahl der Gehäusebauteile grundsätzlich zunächst einmal gegenüber dem Stand der Technik erhöht, doch kann durch geschickte Konstruktion, wie im Nachfolgenden gezeigt wird, der dadurch bedingte Fertigungsmehraufwand durch eine kostengünstige Herstellung der einzelnen Gehäusebauteile, z. B. ohne verlorene Kerne und aufwändige Werkzeuge kompensiert werden.The assembly according to the invention, which is provided for a heating system with two heating circuits, one for space heating and one for hot water, has at least one housing made of plastic housing component, a pump unit and a heat exchanger for domestic water heating and other electrical, mechanical and / or hydraulic Components on. According to the invention, the assembly is designed so that four housing components are provided, each forming a cable routing to the heat exchanger. This solution according to the invention makes it possible to design the housing components, which connect to the heat exchanger, with regard to their material so that they are adapted as well as possible to the intended use. So are the wiring for the heating water, that is also through the primary heat exchanger and through the radiator flows for the space heating, preferably made of a plastic or provided with a coating having a particularly hard surface, so that on the one hand entrained with the conveying liquid particles can exert no abrasive influence on the conduit wall, on the other hand also form deposits in this area. The housing components that connect to the heat exchanger and run the cold or heated hot water can be materially designed by the inventive design so that they are insensitive to water in the optional additives such as chlorine, fluorine and the like and beyond no substances who could get into the drinking water with it. Although the number of housing components is basically initially increased compared to the prior art by the inventive solution, but can be achieved by skillful construction, as shown below, the resulting additional manufacturing costs by a cost-effective production of the individual housing components, eg. B. without lost cores and complex tools can be compensated.

Gemäß einer vorteilhaften Weiterbildung der Erfindung sind mindestens zwei Gehäusebauteile aus unterschiedlichen Kunststoffen gefertigt, wobei die Anordnung der unterschiedlichen Kunststoffe so gewählt ist, dass mindestens das Heizungswasser und das Brauchwasser in unterschiedlichen Kunststoffleitungen geführt sind. Eine solche Anordnung hat den besonderen Vorteil, dass die Gehäusebauteile entsprechend den darin geführten Flüssigkeiten und den sich daraus ergebenen speziellen Anforderungen hergestellt werden können. Vorteilhaft können darüber hinaus auch die Gehäusebauteile, welche die Leitungsführung für das warme und das kalte Brauchwasser bilden, aus unterschiedlichen Kunststoffen bestehen, um auch so den unterschiedlichen Anforderungen Rechnung zu tragen. Dabei kann neben der Wahl der Kunststoffe beispielsweise das Gehäusebauteil für das warme Brauchwasser darüber hinaus besonders leicht austauschbar gestaltet sein, um beispielsweise in Gegenden mit sehr kalkhaltigem Wasser dieses typischerweise am ehesten verkalkende Bauteil schnell und einfach auszutauschen zu können oder ein solches zur Verfügung zu stellen, bei welchem durch Materialwahl des Gehäusebauteils Ablagerungen dieser Art nach Möglichkeit vollständig vermieden werden.According to an advantageous embodiment of the invention, at least two housing components made of different plastics, wherein the arrangement of the different plastics is chosen so that at least the heating water and the service water are guided in different plastic lines. Such an arrangement has the particular advantage that the housing components can be manufactured according to the fluids carried therein and the special requirements arising therefrom. Advantageously, moreover, the housing components, which form the wiring for the hot and cold water, consist of different plastics, so as to take into account the different requirements. Here, in addition to the choice of plastics, for example, the housing component for the hot service water Be particularly easily interchangeable designed to quickly and easily replace, for example, in areas with very limy water this typically calcifying component or to provide such available, in which by choosing the material of the housing component deposits of this kind are avoided if possible completely ,

Vorteilhaft sind dabei mindestens zwei Gehäusebauteile zu einem aus unterschiedlichen Kunststoffen bestehenden Spritzgussteil geformt, sei es, dass diese in einem Werkzeug aus unterschiedlichen Kunststoffen gespritzt sind oder, was nach einer Weiterbildung der Erfindung auch vorgesehen sein kann, dass zwei Gehäusebauteile so zusammengesetzt sind, dass sie quasi wie ein Gehäusebauteil handhabbar sind. Im ersteren Fall ergibt sich der Vorteil, dass nur ein Werkzeug erforderlich ist sowie darüber hinaus auch nur ein zu handhabendes Bauteil entsteht. Wenn hingegen die Gehäusebauteile zu einem gemeinsamen Bauteil zusammengesetzt sind, können diese in einfacher Weise durch eine Rast- oder Schnappverbindung miteinander verbunden werden, so dass ebenfalls nur ein Bauteil zu handhaben ist.Advantageously, at least two housing components are formed into an injection molded part made of different plastics, be it that they are injection-molded in a tool of different plastics or what can also be provided according to a development of the invention that two housing components are assembled so that they almost like a housing component are manageable. In the former case, there is the advantage that only one tool is required and, moreover, only one component to be handled arises. If, however, the housing components are assembled to form a common component, they can be connected to one another in a simple manner by a latching or snap connection, so that likewise only one component is to be handled.

Gemäß einer vorteilhaften Weiterbildung der Erfindung werden die Gehäusebauteile zu einem Bauteil zusammengefasst, die einem Anschlusspaar des Wärmetauschers zugeordnet sind. Dabei ist es üblicherweise so, dass Plattenwärmetauscher Verwendung finden, welche eine im Wesentlichen langgestreckte rechteckige Form haben, wobei an den Schmalseiten jeweils ein Anschlusspaar vorgesehen ist, von denen in Einbaulage der obere Anschluss dem Heizkreis und der untere Anschluss dem Brauchwasserkreis zugeordnet ist. Es bietet sich daher allein schon aufgrund der räumlichen Anordnung an, die Gehöusebauteile zu vereinen, die dem einen oder dem anderen Anschlusspaar des Wärmetauschers zugeordnet sind. Vorteilhaft werden diese formschlüssig ineinandergreifend ausgebildet, so dass spätestens mit Anschluss des Wärmetauschers diese unverrückbar vereint sind.According to an advantageous embodiment of the invention, the housing components are combined to form a component, which are assigned to a terminal pair of the heat exchanger. It is usually the case that plate heat exchangers are used which have a substantially elongated rectangular shape, wherein on the narrow sides in each case a connection pair is provided, of which in installation position of the upper connection is assigned to the heating circuit and the lower connection to the hot water circuit. Therefore, it is only due to the spatial arrangement to unite the Gehöusebauteile, which are assigned to one or the other connection pair of the heat exchanger. These are advantageously form-fitting formed interlocking, so that at the latest with the connection of the heat exchanger they are immovably united.

Zweckmäßigerweise werden die paarweise ineinandergreifenden oder geformten Gehäusebauteile so angeordnet, dass die in Einbaulage an die oberen Anschlüsse des Wärmetauschers anschließenden Gehäusebauteile derart nach außen versetzt ausgebildet sind, dass sie die an die unteren Anschlüsse des Wärmetauschers anschließenden Gehäusebauteile seitlich umgeben. Diese Anordnung ist besonders günstig, da man mit dieser Bauweise erreicht, dass alle Gehäusebauteile und im Wesentlichen vollständig von vorne zugänglich sind, so dass nicht nur ein besonders kompakter und flacher Aufbau der Baueinheit gewährleistet ist, sondern auch die Zugänglichkeit der darin integrierten Komponenten, was insbesondere für Wartungs- und Reparaturarbeiten von Vorteil ist.Conveniently, the paired interlocking or shaped housing components are arranged so that the subsequent mounting position in the upper terminals of the heat exchanger housing components are formed outwardly such that they laterally surround the adjoining the lower connections of the heat exchanger housing components. This arrangement is particularly favorable, since it is achieved with this construction, that all housing components and substantially completely accessible from the front, so that not only a particularly compact and flat construction of the unit is ensured, but also the accessibility of the integrated components, what especially for maintenance and repair is beneficial.

Gemäß einer Weiterbildung der Erfindung weisen die Gehäusebauteile in Einbaulage von vorne zugängliche Einschubgehäuse auf, wobei die paarweise ineinandergreifenden oder geformten Einschubgehäuse so angeordnet sind, dass die Einschubgehäuse in Einbaulage nebeneinander liegen, also ohne Ausbau der Gehäusebauteile, von vorne zugänglich sind.According to one embodiment of the invention, the housing components in the installed position from the front accessible plug-in housing, wherein the mating interlocking or molded plug-in housing are arranged so that the plug-in housing in installation position next to each other, ie without removing the housing components, are accessible from the front.

Wenn, wie oben beschrieben, die in Einbaulage an die oberen Anschlüsse des Wärmetauschers anschließenden Gehäusebauteile nach außen versetzt ausgebildet sind, dann ist es umgekehrt zweckmäßig, die an die unteren Anschlüsse des Wärmetauschers anschließenden Gehäusebauteile zumindest teilweise in Flucht zur zugehörigen Anschlussöffnung anzuordnen, da diese Gehäusebauteile dann kompakt und werkzeugtechnisch einfach ausgebildet sein können. Darüber hinaus ergibt sich durch diese Gesamtanordnung eine besonders kompakte und platzsparende Baueinheit.If, as described above, the housing components adjoining in the installed position to the upper terminals of the heat exchanger are outwardly offset, then it is inversely appropriate to at least partially align the housing components adjacent to the lower connections of the heat exchanger to the associated connection opening, since these housing components then be compact and tool technology can be easily formed. In addition, this arrangement results in a particularly compact and space-saving structural unit.

Um die Einschubgehäuse der an die oberen Anschlüsse des Wärmetauschers anschließenden Gehäusebauteile im Wesentlichen neben die Einschubgehäuse der an die unteren Anschlüsse des Wärmetauschers anschließenden Gehäusebauteile anordnen zu können, ist es zweckmäßig, die Einschubgehäuse der an die oberen Anschlüsse des Wärmetauschers anschließenden Gehäusebauteile mit seitlichem Abstand zu den Anschlüssen anzuordnen und über quer zur Längsachse der Einschubgehäuse verlaufende Kanäle mit diesen leitungszuverbinden. Diese Kanäle ermöglichen es, dass der Raum vor den Anschlusspaaren des Wärmetauschers im Wesentlichen durch die an die unteren Anschlüsse anschließenden Gehäusebauteile, insbesondere auch Einschubgehäuse oder weitere Komponenten genutzt werden kann, wohingegen die an die oberen Anschlüsse des Wärmetauschers anschließenden Gehäusebauteile quasi nach außen verlegt werden. Zwar ist es besonders vorteilhaft, die an die oberen Anschlüsse des Wärmetauschers anschließenden Gehäusebauteile nach außen und die an die unteren Anschlüsse anschließenden Bauteile nach innen zu legen, doch kann dies gegebenenfalls auch umgekehrt günstiger sein, je nach Ausbildung und Aufbau der Anlage. Typischerweise ist zwischen den paar weisen, an den Wärmetauscher anschließenden Gehäusebauteilen ein weiteres zentrales Gehäusebauteil vorgesehen, welches das Pumpenaggregat trägt.In order to be able to arrange the plug-in housings of the housing components adjoining the upper connections of the heat exchanger essentially next to the plug-in housings of the housing components adjoining the lower connections of the heat exchanger, it is expedient for the plug-in housings of the housing components adjoining the upper connections of the heat exchanger to be laterally spaced from the heat exchanger Arranging connections and line connecting over these transversely to the longitudinal axis of the plug-in housing channels with these. These channels make it possible for the space in front of the connection pairs of the heat exchanger to be used essentially by the housing components adjoining the lower connections, in particular also slide-in housings or other components, whereas the housing components adjoining the upper connections of the heat exchanger are moved to the outside as it were. Although it is particularly advantageous to put the adjoining the upper connections of the heat exchanger housing components to the outside and the adjoining the lower terminals components inside, but if necessary, this may also be cheaper, depending on the design and construction of the system. Typically, between the pair of wise, subsequent to the heat exchanger housing components another central housing member is provided which carries the pump unit.

Die anhand von Fig. 1 dargestellte Heizungsanlage weist einen ersten Heizkreis auf, in dem mittels eines Primärwärmetauschers 1 mittels eines Brenners 2 in Kreislauf geführtes Wasser erwärmt wird. Das Wasser wird mittels einer Umwälzpumpe 3 durch den Primärwärmetauscher 1 und nachfolgend einem 3/3-Wegeventil zugeführt, von dem es aus wahlweise eine über ein Rückschlagventil angeschlossenen Überströmleitung 5 oder einem Wärmetauscher 6 in Form eines Plattenwärmetauschers oder den Heizkörpern 7 der Raumheizung zugeführt wird. Durch die Überströmleitung 5 erfolgt auf kurzem Wege eine Rückführung zur Umwälzpumpe 3 und somit zum Primärwärmetauscher 1. Diese Schaltstellung dient zum schnellen Erwärmen des dort im Kreislauf geführten Wassers. In der zweiten Schaltstellung wird das im Primärwärmetauscher 1 erwärmte Wasser dem Plattenwärmetauscher 6 zugeführt, in welchem es im Gegenstrom Brauchwasser erwärmt, welches aus einer Brauchwasserleitung 8 kommt und erwärmt durch eine Wärmwasserleitung 9 den Wärmetauscher 6 verlässt. Das durch den Wärmetauscher 6 geführte Heizwasser gelangt über eine Rückführleitung 10 wieder zur Umwälzpumpe 3 und somit zum Primärwärmetauscher 1. In der dritten Schaltstellung des Ventils 4 wird das im Primärwärmetauscher 1 erwärmte Wasser den Heizkörpern 7 der Raumheizung 7 zugeführt und dann über eine Rückführleitung 11 wiederum zur Umwälzpumpe 3 und zurück zum Primärwärmetauscher 1.The heating system shown with reference to FIG. 1 has a first heating circuit, in which by means of a primary heat exchanger 1 by means of a burner 2 in circulated water is heated. The water is supplied by means of a circulation pump 3 through the primary heat exchanger 1 and subsequently to a 3/3-way valve, from which it is optionally supplied via a check valve connected overflow 5 or a heat exchanger 6 in the form of a plate heat exchanger or the radiators 7 of the space heater. Through the overflow 5, a return to the circulation pump 3 and thus to the primary heat exchanger 1 is carried out over a short path. This switching position is used for rapid heating of the water circulated there. In the second switching position, the heated water in the primary heat exchanger 1 is supplied to the plate heat exchanger 6, in which it heated hot water in countercurrent, which comes from a service water pipe 8 and heated by a heat water pipe 9 leaves the heat exchanger 6. The guided through the heat exchanger 6 heating water passes through a return line 10 back to the circulation pump 3 and thus to the primary heat exchanger 1. In the third switching position of the valve 4, the heated water in the primary heat exchanger 1 is supplied to the radiators 7 of the space heater 7 and then turn on a return line 11 to the circulation pump 3 and back to the primary heat exchanger. 1

Wie aus Fig. 1 ersichtlich ist, sind die Bauteile 3 bis 6 und 10 sowie weitere, in der Figur nicht im Einzelnen dargestellte Komponenten, in einer Baueinheit 12 angeordnet, die in Fig. 1 durch den mit 12 bezifferten rechteckigen Rahmen dargestellt ist.As can be seen from Fig. 1, the components 3 to 6 and 10 and other, not shown in detail in the figure components, in one Assembly 12 arranged, which is shown in Fig. 1 by the numeral 12 numbered rectangular frame.

Eine solche Baueinheit 12, wie sie typischerweise für so genannte wandmontierbare Heizthermen vorgesehen ist, ist anhand von Fig. 2 dargestellt. Die Baueinheit 12 weist ein zentrales Pumpengehäusebauteil 13 auf, welches das Kreiselrad der Umwälzpumpe 3 aufnimmt und saugseitig einen Luftabscheider aufweist, dessen Schnellentlüfter 14 in Fig. 2 erkennbar ist. Das Pumpengehäusebauteil 13 liegt mit Abstand vor dem Plattenwärmetauscher 6 und weist einen in Einbaulage nach oben gerichteten Druckstutzen 15 auf, welcher zur Leitungsverbindung mit dem Primärwärmetauscher 1 vorgesehen ist. Das Pumpengehäusebauteil 13 trägt stirnseitig den Elektromotor 16 der Pumpe, der Klemmenkasten 17 des Motors 16 ist hier auf dem Elektromotor 16 angeordnet und nimmt die gesamte Steuer- und Regelelektronik auf. Rechts und links (gemäß Figur 2) schließen an das Pumpengehäusebauteil 13 so genannte Armaturengehäuse 18 und 19 an, die jeweils aus zwei Gehäusebauteilen 20 und 21 bzw. 22 und 23 bestehen. Diese Gehäusebauteile 20 - 23 sind anhand der Fig. 3 und 4 im Einzelnen dargestellt, es handelt sich hierbei um Kunststoffspritzgussteile, die an die Anschlusspaare des Plattenwärmetauschers 6 anschließen.Such a unit 12, as is typically provided for so-called wall-mounted heating baths, is illustrated with reference to FIG. 2. The assembly 12 has a central pump housing component 13, which receives the impeller of the circulation pump 3 and suction side has an air separator, the quick exhaust fan 14 in FIG. 2 can be seen. The pump housing component 13 is located at a distance in front of the plate heat exchanger 6 and has a mounting in upwardly directed discharge nozzle 15, which is provided for line connection to the primary heat exchanger 1. The pump housing component 13 carries the front side of the electric motor 16 of the pump, the terminal box 17 of the motor 16 is arranged here on the electric motor 16 and receives all the control electronics.

These housing components 20 - 23 are shown in detail with reference to FIGS. 3 and 4, these are plastic injection molded parts, which connect to the terminal pairs of the plate heat exchanger 6.

Die Gehäusebauteile 20 und 22 schließen rückseitig an die in Fig. 4 sichtbaren oberen Anschlüsse der Anschlusspaare 24 und 25 des Plattenwärmetauschers 6 an und sind für die Leitungsführung des durch den Primärwärmetauscher 1 laufenden Heizwassers bestimmt, also das Wasser, das durch den Primärwärmetauscher 1 und dann wahlweise durch die Überströmleitung 5, den Plattenwärmetauscher 6 oder die Heizkörper 7 strömt. Diese Gehäusebauteile 20 und 22 sind daher aus einem Kunststoff, bespielsweise Polyphenylensulfid gefertigt, der den Anforderungen dieser im Kreislauf geführten Wärmeträgerflüssigkeit besonders Rechnung trägt. An dem unteren Anschluss des Anschlusspaares 25 schließt das Gehäusebauteil 23 an, welches ausschließlich kaltes Brauchwasser führt. Das im Plattenwärmetauscher 6 erwärmte Brauchwasser tritt über den unteren Anschluss des Anschlusspaares 24 aus, an den das Gehäusebauteil 21 anschließt. Die Gehäusebauteile 21 und 23 sind hinsichtlich Materialwahl insbesondere im Hinblick auf die Brauchwasserführung optimiert, und bestehen beispielsweise aus Polyamid ,wobei das Gehäusebauteil 21 an die besonderen Anforderungen des erwärmten Brauchwassers angepasst ist, d. h. insbesondere im Hinblick auf Kalkablagerungen entsprechend ausgerüstet ist und/oder einen antibakteriell wirkenden Zusatzwirkstoff enthält.The housing components 20 and 22 connect the back to the visible in Fig. 4 upper terminals of the pairs of terminals 24 and 25 of the plate heat exchanger 6 and are intended for the routing of running through the primary heat exchanger 1 heating water, ie the water passing through the primary heat exchanger 1 and then optionally through the overflow 5, the plate heat exchanger 6 or the radiator 7 flows.
