Heizungsanlage mit einem Kondensationskessel, mit einem Überströmventil und mit einer in einer Vorlaufleitung liegenden U mwälzpumpe, die das Vorlaufwasser über Thermostatventile an Verbraucher liefert, die durch eine Rücklaufleitung mit dem Kondensationskessel verbunden sind, dadurch gekennzeichnet, dass das Überströmventil (7) zur Umwälzpumpe (3) hydraulisch antiparallel geschaltet ist.1. Heating system with a condensation boiler, with an overflow valve and with a circulation pump located in a flow line, which supplies the flow water to consumers via thermostatic valves, which are connected to the condensation boiler by a return line, characterized in that the overflow valve (7) to the circulation pump (3) is hydraulically connected anti-parallel. 2. Heizungsanlage nach Anspruch 1, dadurch gekennzeichnet, dass die Umwälzpumpe (3) und das Überströmventil (7) eine Baueinheit bilden.2. Heating system according to claim 1, characterized in that the circulation pump (3) and the overflow valve (7) form a structural unit. BESCHREIBUNGDESCRIPTION Die vorliegende Erfindung betrifft eine Heizungsanlage mit einem Kondensationskessel und den im Oberbegriff des Patentanspruchs 1 angeführten Merkmalen.The present invention relates to a heating system with a condensation boiler and the features specified in the preamble of patent claim 1. Solche Heizungsanlagen mit einem Kondensationskessel sind bekannt. Sie weisen eine Umwälzpumpe in einer Vorlaufleitung auf, welche das Vorlaufwasser über Thermostatventile an Verbraucher liefert. In den Verbrauchern wird das Vorlaufwasser durch Abgabe der Wärme an die zu beheizenden Räume abgekühlt und durch eine Rücklaufleitung in den Kondensationskessel zurückgeführt. Ein zu den Thermostatventilen und zu den Verbrauchern parallel liegendes Überströmventil lässt beim Schliessen der Thermostatventile das Vorlaufwasser direkt in die Rücklaufleitung fliessen.Such heating systems with a condensation boiler are known. They have a circulating pump in a flow line, which supplies the flow water to consumers via thermostatic valves. In the consumers, the supply water is cooled by dissipating the heat to the rooms to be heated and returned to the condensation boiler through a return line. An overflow valve located parallel to the thermostatic valves and consumers allows the supply water to flow directly into the return line when the thermostatic valves are closed. Dies hat den Nachteil, dass das auf die Vorlauftemperatur aufgeheizte Vorlaufwasser die Rücklauftemperatur der Heizungsanlage erhöht. Die Erhöhung der Rücklauftemperatur hat zur Folge, dass die für einen sparsamen Betrieb des Kondensationskessels erwünschte maximale Kondensation in der Rücklaufleitung nicht stattfinden kann.This has the disadvantage that the flow water heated to the flow temperature increases the return temperature of the heating system. The increase in the return temperature means that the maximum condensation in the return line that is required for economical operation of the condensation boiler cannot take place. Der vorliegenden Erfindung liegt die Aufgabe zugrunde, diesen Nachteil zu beseitigen und eine Heizungsanlage zu schaffen, bei welcher darüber hinaus die Wassermenge im Verbraucherkreis variabel gemacht und damit die Verweilzeit des Wassers im Heizkreis beim Schliessen der Thermostatventile vergrössert werden kann. Die Vergrösserung der Verweilzeit hat zur Folge, dass das Rücklaufwasser immer eine möglichst niedrige Temperatur aufweist, womit eine maximale Kondensation möglich wird.The object of the present invention is to eliminate this disadvantage and create a heating system in which the amount of water in the consumer circuit can also be made variable and the residence time of the water in the heating circuit can be increased when the thermostatic valves are closed. The increase in the residence time means that the return water is always at the lowest possible temperature, which means that maximum condensation is possible. Die gestellte Aufgabe ist durch Merkmale des Patentanspruches 1 gelöst.The task is solved by features of patent claim 1. s Ein Ausführungsbeispiel des Gegenstandes der Erfindung wird nachfolgend anhand einer einzigen schematischen Zeichnung näher beschrieben. Eine Heizungsanlage weist einen Kondensationskessel 1 auf, welcher mit Hilfe einer in ihrer Vorlaufleitung 2 liegenden Umwälzpumpe 3 heisses io Wasser über Thermostatventile 4 an Verbraucher 5 liefert, die über eine Rücklaufleitung 6 mit dem Kondensationskessel 1 verbunden sind. Ein Überströmventil 7 ist zwischen der Saugseite und der Druckseite der Umwälzpumpe 3 unmittelbar an dieser hydraulisch so angeschlossen, dass 15 seine Durchlassrichtung der Durchflussrichtung der Umwälzpumpe 7 entgegengesetzt ist, das heisst, das Überströmventil 7 ist zur Umwälzpumpe 3 hydraulisch antiparallel geschaltet. Beim Schliessen der Thermostatventile 4 fliesst durch das Überströmventil 7 Vorlaufwasser also in 20 Gegenrichtung zum Vorlaufstrom, wie dies durch Pfeile in der Zeichnung gezeigt ist. Durch diese Anordnung des Überströmventils 7 wird erzielt, dass die Wassermenge im Verbau-cherkreis variabel und damit die Verweilzeit beim Schliessen der Thermostatventile 4 grösser wird. Da kein Vorlaufwasser 25 direkt in die Rücklaufleitung 6 gelangt, besteht in der Rücklaufleitung 6 immer die niedrigst mögliche Rücklauftemperatur des Wassers, was eine für einen ökonomischen Betrieb des Kondensationskessels 1 erwünschte grösstmögliche Kondensation ergibt.s An embodiment of the subject matter of the invention is described in more detail below with reference to a single schematic drawing. A heating system has a condensation boiler 1 which, with the aid of a circulating pump 3 located in its flow line 2, supplies hot water via thermostatic valves 4 to consumers 5, which are connected to the condensation boiler 1 via a return line 6. An overflow valve 7 is hydraulically connected between the suction side and the pressure side of the circulating pump 3 directly in such a way that its flow direction is opposite to the flow direction of the circulating pump 7, i.e. the overflow valve 7 is connected hydraulically anti-parallel to the circulating pump 3. When the thermostatic valves 4 are closed, flow water flows through the overflow valve 7 in the opposite direction to the flow flow, as shown by arrows in the drawing. This arrangement of the overflow valve 7 means that the amount of water in the consumer circuit is variable and the dwell time when the thermostatic valves 4 are closed is therefore greater. Since no supply water 25 reaches the return line 6 directly, the return line 6 always has the lowest possible return temperature of the water, which results in the greatest possible condensation desired for economical operation of the condensation boiler 1 . 30 Die vorliegende Lösung verwendet eine Umwälzpumpe 3 sowie ein Überströmventil 7 üblicher Ausführung. Es ist aber auch denkbar, die Umwälzpumpe 3 und das Überströmventil 7 als eine bauliche Einheit zu gestalten, wodurch deren Montage in der Heizungsanlage noch einfacher wird.30 The present solution uses a circulating pump 3 and an overflow valve 7 of conventional design. But it is also conceivable to design the circulating pump 3 and the overflow valve 7 as a structural unit, which makes their installation in the heating system even easier. 35 Durch Verwendung von Bestandteilen, d.h. einer Umwälzpumpe und eines Überströmventils, die in bekannten Heizungsanlagen ohnedies vorzusehen sind, entstehen für die beschriebene Anordnung keine Mehrkosten im Vergleich mit bekannten Lösungen. Die geschilderten Massnahmen 40 ermöglichen einen besonders wirkungsvollen Betrieb des Kondensationskessels und bringen somit bedeutende Ersparnisse an Heizungskosten.By using components, i.e. a circulating pump and an overflow valve, which are to be provided in any case in known heating systems, there are no additional costs for the arrangement described in comparison with known solutions. The measures 40 described enable the condensation boiler to be operated particularly efficiently and thus result in significant savings in heating costs. 1 Blatt Zeichnungen1 sheet of drawings
