Die erfindungsgemäße Anordnung mit den Merkmalen des Hauptanspruchs hat den Vorteil, daß das Heizgerät im reinen Zirkulationsbetrieb nur eingeschaltet wird, wenn die Temperatur des Wärmeübertragers auf die Erhaltungstemperatur des Zirkulationswassers abgesunken ist. Dadurch wird auch ohne Erwärmung und Installation eines Speichers die Einschalthäufigkeit des Heizgerätes in sonst wärmebedarfsarmen Zeiten verringert und auf den tatsächlichen Bedarf zur Erhaltung der Zirkulationswassertemperatur abgestellt.The arrangement according to the invention with the features of The main claim has the advantage that the heater in the pure Circulation mode is only switched on when the Temperature of the heat exchanger to the maintenance temperature of the circulation water has dropped. This will also without heating and installing a store Switch-on frequency of the heater in otherwise low heat consumption times and on the actual need to maintain the Circulation water temperature turned off.

Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Ausgestaltungen der Anordnung nach dem Hauptanspruch möglich.By the measures listed in the subclaims advantageous embodiments of the arrangement according to Main claim possible.

Zum Steuern der Wärmequelle bei reinem Zirkulationsbetrieb kann vorteilhaft ein die Heiztemperatur des Wärmeübertragers erfassender Temperatursensor vorgesehen sein. Zusätzlich dazu kann zwischen dem Wärmeübertrager und dem Warmwasseranschluß des Heizgerätes ein Sensor zur Erkennung der Warmwasser- bzw. Zapfwassertemperatur vorgesehen sein.To control the heat source in pure circulation mode can advantageously be the heating temperature of the heat exchanger detecting temperature sensor can be provided.

Die Zirkulationswassermenge kann einfach und betriebssicher durch die Anordnung eines Wassermengenbegrenzers in der Zirkulationsleitung auf einen unterhalb der Einschaltwassermenge liegenden Wert begrenzt sein. Der unterschiedliche Wasserstrom zwischen der Zirkulations- und der normalen Zapfwassermenge kann vorteilhaft durch eine zwischen dem Kaltwasseranschluß und dem Wärmeübertrager angeordneten Wassermengensensor ermittelt sein.The amount of circulation water can be simple and reliable by arranging a water flow limiter in the Circulation line to one below the Inlet water quantity may be limited.

Bei Anlagen mit einem Heizgerät, dessen Warmequelle auch einen Wärmeübertrager in einem Heizungswassernetz speist (Umlaufwasserheizer), kann die Zirkulationswassererwärmung ohne Vorrat parallel bei der Heizungswassererwärmung erfolgen, so daß die Wärmezufuhr in das Heizungswassernetz nicht unterbrochen oder verzögert wird. For systems with a heater, its heat source too feeds a heat exchanger in a heating water network (Circulation water heater), can the circulation water heating without stock in parallel with heating water heating take place so that the heat supply in the heating water network is not interrupted or delayed.

Die parallele Erwärmung von Heizungswasser und Zirkulationswasser läßt sich einfach realisieren, wenn beide Wärmeübertrager zu einer Baueinheit vereinigt sind.The parallel heating of heating water and Circulation water can be easily realized if both Heat exchangers are combined into one structural unit.

An den Warmwasseranschluß 32 ist eine Leitung 34 angeschlossen, die zu Zapfstellen 36 führt. In dem Kaltwasserstrang 26 ist ein Wassermengenbegrenzer 38 eingebaut, der auf den vorgegebenen Maximalwert der pro Zeiteinheit durchfließenden Zapfwassermenge eingestellt ist. Am Warmwasserstrang 30 ist ein Temperatursensor 40 vorgesehen, der mit der nicht dargestellten Steuereinrichtung des Gerätes verbunden ist, welche u. a. die Temperatur des durchlaufenden Zapfwassers steuert bzw. regelt.The fin block of the heat exchanger 14 is also from Pipes carrying industrial water that passes through a Cold water line 26 with a cold water connection 28 and over a hot water line 30 with a hot water connection 32 are connected. At the hot water connection 32 is one Line 34 connected, which leads to taps 36. In the cold water line 26 is a water quantity limiter 38 built in, to the specified maximum value of the pro Time unit flowing through the tap water quantity is set. A temperature sensor 40 is on the hot water line 30 provided that with the not shown Control device of the device is connected, which u. a. controls the temperature of the tap water flowing through or regulates.

Die dargestellte Anlage hat ferner einen Strömungskreis für Zirkulationswasser, der über eine Zirkulationsleitung 42 führt. Diese hat einen inneren Leitungsstrang 44, der an einem Anschluß 46 vom Kaltwasserstrang 26 abzweigt und über einen Wassermengenbegrenzer 48 zu einem Zirkulationsanschluß 50 des Gerätes führt. Von dort geht die Zirkulationsleitung 42 über einen Rückflußverhinderer 52 und eine Zirkulationspumpe 54 zu der Zapfstelle 36 weiter, wo sie an die in das Zapfwasser führende Leitung 34 entsprechend verzweigt angeschlossen ist.The system shown also has a flow circuit for Circulation water, which via a circulation line 42nd leads.

The circulation pump 54 can continue by known means such. B. by a Timer, be controlled.

Der Wassermengensensor 56 erkennt den unterschiedlichen Wasserstrom zwischen dem Zirkulationsbetrieb und der normalen Zapfwasserentnahme. Wenn die Temperatur am Wärmeübertrager 14 unter einem der Zirkulationstemperatur zugeordneten Wert abgefallen ist, wird der Gasbrenner 12 mit der für die Erwärmung des Zirkulationswassers auf einen vorgegebenen Sollwert bzw. auf die Erhaltungstemperatur erforderlichen Leistung in Betrieb gesetzt. Zum Erfassen der Temperatur am Warmeübertrager 14 kann der entsprechend ausgebildete Temperatursensor 40 dienen oder ein zusätzlicher Temperatursensor unmittelbar am Warmeübertrager 14 vorgesehen sein. Wenn gleichzeitig eine Warmeanforderung aus dem Heizungsnetz vorliegt, kann die Zirkulationswassererwärmung im Vorrang erfolgen. Wenn jedoch bei Wärmeanforderung aus dem Heizungsnetz die Temperatur des Wärmeübertragers über dem Sollwert liegt, kann ein Parallelbetrieb von Zirkulationswassererwärmung und Heizungswassererwärmung vorgesehen werden.The water quantity sensor 56 recognizes the different Water flow between the circulation and the normal tap water withdrawal. If the temperature at Heat exchanger 14 below one of the circulation temperature assigned value has dropped, the gas burner 12 with the one for heating the circulation water to one specified setpoint or to the maintenance temperature required power put into operation.
