Mehrkesselheizungsanlage Die Erfindung betrifft eine Mehrkesselheizungsan- lage für mehrere Heizungsgruppen, wobei für jede Heizungsgruppe zwei Umwälzpumpen vorgesehen sind.
Es ,ist :bei Heizungsanlagen für .mehrere Heizungs- gruppen allgemein bekannt, je Heizungsgruppe zwei Umwälzpumpen vorzusehen. Dadurch sollvermieden werden, @dass bei Au sfall einer Pumpe auch die zugehö- rige Heizungsgruppe ausfällt. Es kommt jedoch häufig vor, .dass eine Pumpe über einen relativ langen Zeitraum störungsfrei in Betrieb ist und:
bei einem dann plötzlichen Ausfallen dieser Pumpe die während dieses: Zeitraumes unbenutzte Pumpe nicht ,mehr betriebsfähig ist. Diesem Mangel hat .man :bisher !dadurch abzuhelfen versucht, dass die beiden Umwälzpumpen durch :Umschalten von Hand innerhalb bestimmter Zeitabstände :abwechselnd in Betrieb genommen wurden. Das erfordert jedoch einen zusätzlichen Bedienungs,aufwarnd.
Der Erfindung liegt die Aufgabe zugrunde, ,die vorgerannten Nachteile zu vermeiden. Die Lösung ,dieser Aufgabe wird. in erster Linie darin gesehen, dass die beiden zu einer Heizungsgruppe ,gehörenden Umwälz- pumpen in bestimmten Zeitintervallen abwechselnd durch ein elektronisches Schaltglied ein- und ausgeschaltet werden.
Bei einer vorteilhaften Ausgestaltung der Heizungsanlage ,gemäss der Erfindung erfolgt mittels des für die Ein- und Ausschaltung der Umwälzpumpen vorgesehenen elektronischen Schaltgliedes auch das abwechselnde Ein- und Ausschalten der Kessel und Boiler.
Zweckmässig kann die Schaltung der Umwälzpumpe sowie der Kessel und Boiler durch das Schaltglied für die Umschaltung der Heizungsanlage von Tag- auf Nachtbetrieb und umgekehrt erfolgen. Dadurch ist die Anwendung der ,Erfindung ohne zusätzliche Sehaltglieder möglich.
Anhand eines Ausführungsbeispieles äst die Erfin- dung nachstehend näher erläutert, wobei .auf den in der Zeichnung dargestellten Schaltplan Bezug genommen wird. In diesem Schaltplan sind Vorlaufleitungen durch Vollinien und Rücklaufleitungen durch gestrichelte Linien dargestellt.
Die beiden Kessel 1 sind ebenso wie die beiden Boiler 2 parallel geschaltet. Die Temperatur der Kessel 1 wind durch Aussenthermostate 3 gesteuert, während die Temperatur der Heizungsgruppen 4 durch über Raumthermostate gesteuerte Mischventile 6 eingestellt wird. Das aus den Kesseln 1 kommende heisse Wasser gelangt zunächst über Leitungen 7 in einen Vorlaufverteiler B.
Von hier wird das heisse Wasser mittels Umwälzpumpen 9 oder 10, die jeweis abwechselnd in Betrieb gesetzt werden, den Heizungsgruppen 4 zugeführt. über Rücklaufleitungen 11 gelangt das nunmehr kältere Wasser in einen Rücklaufsammler 12 und von hier aus über Leitungen 13 zurück in die Kessel 1.
Das aus Aden, Boilern 2 kommende .heisse Wasser wird Über Leitungen 14, die einen Warmwasserfühler 15 aufweisen, einem Verbraucher 1'6 zugeführt.
Die beiden :Kessel 1 werden wahlweise in Betrieb -enommen, wobei das Ein- und Ausschalten der Kessel vorzugsweise über das gleiche Schaltglied erfolgt wie das Ein- und Ausschalten der Umwälzpumpen 9 und 10.
Jeder Kessel 1 weist zweckmässigerweise neben den Aussenthermostaten 3 zwei weitere, nicht näher #dar#ge- stellte Thermostate auf, von denen der erste bei Unter- schreiten der von den Aussenthermostaten 3 eingestell- ten Temperatur die Einschaltung des zweiten .Kessels bewirkt, während der zweite Thermostat erst dann, wenn der zweite Kesseldia gleiche Temperatur wie der erste Kessel erreicht, in den Leitungen 7 vorgesehene motorgesteuerte Drosselklappen 17 öffnet.
Dadurch wird vermieden, @dass @bei Hänzuschalten des zweiten Kessels kaltes -Wasser in den Vorlaufverteiler 8 .gelangt.

Multi-boiler heating system The invention relates to a multi-boiler heating system for several heating groups, with two circulation pumps being provided for each heating group.
It is generally known in heating systems for several heating groups to provide two circulation pumps for each heating group. This is to avoid @ that if a pump fails, the associated heating group also fails. However, it often happens that a pump has been in operation for a relatively long period of time and:
In the event of a sudden failure of this pump, the pump that was not used during this period is no longer operational. So far! Has tried to remedy this deficiency by starting the two circulation pumps alternately by: Switching by hand within certain time intervals. However, this requires an additional operation, warning.
The invention is based on the object of avoiding the aforementioned disadvantages. The solution to this task will be. primarily seen in the fact that the two circulating pumps belonging to a heating group are alternately switched on and off at certain time intervals by an electronic switching element.
In an advantageous embodiment of the heating system according to the invention, the boiler and boiler are alternately switched on and off by means of the electronic switching element provided for switching the circulating pumps on and off.
The circulation pump as well as the boiler and boiler can expediently be switched by the switching element for switching the heating system from day to night operation and vice versa. As a result, the invention can be used without additional holding members.
The invention is explained in more detail below using an exemplary embodiment, with reference being made to the circuit diagram shown in the drawing. In this circuit diagram, flow lines are shown by solid lines and return lines by dashed lines.
The two boilers 1, like the two boilers 2, are connected in parallel. The temperature of the boiler 1 is controlled by external thermostats 3, while the temperature of the heating groups 4 is set by mixing valves 6 controlled by room thermostats. The hot water coming from the boilers 1 first reaches a flow distributor B via lines 7.
From here the hot water is fed to the heating groups 4 by means of circulating pumps 9 or 10, which are alternately put into operation. The water, which is now colder, reaches a return collector 12 via return lines 11 and from here back into the boiler 1 via lines 13.
The hot water coming from Aden, boilers 2 is fed to a consumer 1'6 via lines 14 which have a hot water sensor 15.
The two: Boiler 1 are optionally put into operation, with the boilers being switched on and off preferably via the same switching element as the circulation pumps 9 and 10 are switched on and off.
In addition to the external thermostats 3, each boiler 1 expediently has two further thermostats (not shown), of which the first causes the second boiler to be switched on when the temperature set by the external thermostat 3 is undershot Second thermostat only when the second boiler reaches the same temperature as the first boiler, motor-controlled throttle valves 17 provided in the lines 7 open.
This prevents cold water from reaching the flow distributor 8 when the second boiler is switched off.
