Abstract

Die Erfindung betrifft eine Warmwasser-Versorgungsanlage, mit einem von einem Kaltwasseranschluß (28) über einen Wärmeübertrager (14) eines Heizgerätes zu Zapfstellen (36) führenden Leitungssystem für Zapfwasser und mit einem Strömungskreis für Zirkulationswasser, der über den Wärmeübertrager (14) und eine eine Zirkulationspumpe (54) enthaltende Zirkulationsleitung führt, die an das Leitungssystem für Zapfwasser angeschlossen ist, und ferner mit Steuermitteln im Heizgerät, welche dessen Wärmequelle mit einer auf die Zapfwassermenge abgestellten Leistung erst aktivieren, wenn die dem Warmeübertrager (14) zufließende Wassermenge die sogenannte Einschaltwassermenge überschreitet.The invention relates to a hot water supply system, with one of a cold water connection (28) over a Heat exchanger (14) of a heater for tapping points (36) leading piping system for tap water and with one Flow circuit for circulation water, which over the Heat exchanger (14) and a circulation pump (54) containing circulation line leads to the Piping system for tap water is connected, and further with control means in the heater, which is its heat source with a power based on the amount of tap water activate when the one flowing to the heat exchanger (14) Water quantity the so-called switch-on water quantity exceeds.

Es wird vorgeschlagen, daß die Zirkulationswassermenge auf einen unterhalb der Einschaltwassermenge liegenden Wert begrenzt ist und bei reinem Zirkulationsbetrieb die Wärmequelle mit der für die Erhaltung einer vorgegebenen Zirkulationswassertemperatur erforderlichen Leistung gesteuert ist. Dadurch ist ohne Anordnung eines zusätzlichen Speichers ein wirtschaftlicher Zirkulationswasserbetrieb mit verringerter Einschalthäufigkeit der Wärmequelle möglich.

Figure 00000001
It is proposed that the circulation water quantity is limited to a value below the switch-on water quantity and, in the case of pure circulation operation, the heat source is controlled with the power required to maintain a predetermined circulation water temperature. As a result, economical circulation water operation with a reduced switch-on frequency of the heat source is possible without arranging an additional storage tank.
