   <Desc/Clms Page number 1> 
    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.
