einem Heizwasser führenden Leitungssystem 12, 14 eines
Heizgerätes. Ein im Leitungssystem 12, 14 angeordneter und durch
einen Brenner
15 von Verbrennungsgasen beaufschlagter
Primärwärmeübertrager 16 versorgt den Speicher 10 über den
Vorlaufabschnitt 12 dieses Leitungssystems und über einen
Vorlaufanschluß 12a des Speichers 10 mit Heizwasser für die

Um den Wirkungsgrad der Wärmeübertragung vom Heizwasser auf
das in der Rohrschlange 26 fließende Brauchwasser zu
erhöhen, verläuft eine Leitung 32 koaxial zu der im Speicher
10 liegenden Rohrschlange 26. Dabei ist das eine Ende der
koaxialen Leitung 32 als im Speicher 10 liegendes offenes
Ende 34 ausgebildet, während das andere Ende 36 mit dem

10 geführte Anschlußstutzen 44 mit einer Außenwand 52
gegenüber einer Innenwand 54 einer zum Rücklaufanschluß 14a
gehörenden Muffe 56 abgeschlossen ist. Über die Muffe 56

angeordnete Rohrschlange 26 und die koaxiale Leitung 32 als
Doppelwendel mit zwei Windungen ausgebildet, wodurch die
Wärmeübertragungsfläche, gegenüber dem ersten
Ausführungsbeispiel vergrößert ist.In the exemplary embodiment according to FIG. 3, this is in the
Der Speicher 10 ist weiterhin mit einer als elastischer
Membran 60 ausgebildeten Zwischenwand versehen, die eine das
Heizwasser führende Gehäusehälfte 62 von einer ein
Gasvolumen aufnehmenden Gehäusehälfte 64 trennt. Dabei
weisen beide Gehäusehälften 62, 64 an ihren Enden umlaufende
Kragen 66, 68 auf, zwischen denen die Membran 60 mit Hilfe
einer Ringwulst 70 eingespannt ist. Der sich zwischen

Stickstoff gefüllt, der ein Druckpolster aufbaut. Die
Gehäusehälfte 62 ist weiterhin mit einem Anschlußstutzen 72
für einen Schnellentlüfter versehen, durch den im Heizwasser
befindlicher Sauerstoff ausgeschieden werden kann.The
Durch diese Merkmale ist es möglich, die im Speicher 10,
oder, wenn der Speicher 10 in einem Heizungsnetz integriert
ist, die im Heizungsnetz auftretenden Volumenänderungen
aufgrund von Temperaturschwankungen zu kompensieren. Der
dann gleichzeitig als Ausdehnungsgefäß ausgebildete Speicher
10 trägt zu einer besonders kompakten Bauweise eines
Heizgeräts bei.These features make it possible to store the data

Bei Brauchwasserentnahme über die Rohrschlange 26 wird
gleichzeitig durch die im Rücklaufabschnitt 14 angeordnete
Heizwasserpumpe 20 im Speicher 10 befindliches Heizwasser
durch das offene Ende 34 der koaxialen Leitung 32 gefördert,
wobei ein erhöhter Wärmeaustausch zwischen dem in der
koaxialen Leitung 32 geförderten Heizungswasser und dem in
der Rohrschlange 26 fließenden Brauchwasser stattfindet.When hot water is withdrawn via the
Der Wärmeaustausch findet im Gegenstromprinzip statt, d. h.
der Kaltwasseranschluß 28 und der Warmwasseranschluß 30 der
Rohrschlange 26 sind so gewählt, daß in der Rohrschlange 26
fließendes Brauchwasser entgegengesetzt zu dem in der
koaxialen Leitung 32 geförderten Heizwasser fließt, wodurch
der Wärmeübertragungsfaktor weiter verbessert wird. Im
Gegensatz zum Gleichstromprinzip kann die Endtemperatur des
in der Rohrschlange 26 fließenden Brauchwassers über die
Endtemperatur des in der koaxialen Leitung 32 fließenden und
sich abkühlenden Heizwassers gesteigert werden.The heat exchange takes place in the counterflow principle, i. H.

Da die Rohrschlange 26 mit einem unter Druck stehenden
Leitungsnetz verbunden ist und als Wärmeübertrager fungiert,
muß sie einerseits druckbeständig sein und andererseits aus
einem Material bestehen, daß eine gute Wärmeleitfähigkeit
aufweist; daher wird als Material für die Rohrschlange 26
vorzugsweise Kupfer verwendet. Da die koaxiale Leitung 32
und die Manschette 40 nur als Strömungsführung für das
Heizwasser dienen, sind beide aus Kunststoff herstellbar.Since the
Um die koaxiale Leitung 32 von der Rohrschlange 26 zu
beabstanden, sind zwischen beiden längs verlaufende Stege 58
angeordnet, die, wie die Figuren 4 - 8 zeigen,
unterschiedlich ausbildbar sind. Figur 4 zeigt eine erste
Ausführungsform von Stegen 58, die durch ein einziges
Fertigungsverfahren gleichzeitig mit der Herstellung der
Rohrschlange 26 aus dem Rohrschlangenmaterial herstellbar
sind. In Figur 5 sind die koaxiale Leitung 32 und die Stege
58 einteilig hergestellt, in Figur 6 sind sowohl koaxiale
Leitung 32, Stege 58 und Rohrschlange 26 einteilig
ausgebildet. Figur 7 und Figur 8 zeigen eine vierte und
fünfte Ausführungsform von Stegen 58, die in der Anordnung
modifiziert sind, aber von der Fertigung wie die ersten drei
Ausführungsformen herstellbar sind.Around the
