Abstract

Die Erfindung betrifft eine Heizungsanlage mit einem Wärmeerzeuger, der einen Wärmeübertrager mit Wärme versorgt, wobei der Wärmeübertrager ausgangsseitig einen Heizkreis mit Heizkörpern und einem Brauchwasserladekreis für einen Brauchwasserspeicher mit Warmwasser speist, wobei im unteren Bereich des Brauchwasserspeichers kaltes Wasser entnommen, über eine Brauchwasser-Ladepumpe und den Wärmeübertrager geleitet im oberen Bereich des Brauchwasserspeichers erwärmt wieder zugeführt wird und wobei dem Brauchwasserspeicher in einem Brauchwasserkreis im unteren Bereich Kaltwasser zuführbar und im oberen Bereich über angeschlossene Zapfstellen warmes Brauchwasser entnehmbar ist. Ist nach der Erfindung vorgesehen, dass der Warmwasser-Ausgang des Brauchwasserkreises vor den Zapfstellen über eine Zirkulationsleitung und einen Rückflussverhinderer mit dem Eingang der Brauchwasser-Ladepumpe verbunden ist, die zwischen dem Kaltwasser-Ausgang des Brauchwasserspeichers für den Brauchwasserladekreis und dem Wärmeübertrager eingeschleift ist und dass zwischen dem Kaltwasser-Ausgang des Brauchwasserspeichers für den Brauchwasserladekreis und die Brauchwasser-Ladepumpe ein Lade-Wassermengenbegrenzer eingeschleift ist, der auf eine vorgebbare Lade-Wassermenge festgelegt ist, dann sind der Brauchwasserladekreis und der Zirkulationskreis so miteinander gekoppelt, dass die Brauchwasser-Ladepumpe auch als Zirkulationspumpe dient.

Figure 00000001
The invention relates to a heating system with a heat generator that supplies a heat exchanger with heat, the heat exchanger on the output side supplying a heating circuit with radiators and a domestic water charging circuit for a domestic hot water tank with hot water, cold water being drawn from the lower region of the domestic water tank, via a domestic water charging pump and the heat exchanger conducted in the upper area of the domestic hot water tank is heated again and the cold water can be supplied to the domestic hot water tank in a domestic hot water circuit in the lower area and hot domestic water can be extracted in the upper area via connected taps. It is provided according to the invention that the hot water outlet of the hot water circuit before the tap is connected via a circulation line and a backflow preventer to the inlet of the hot water charging pump, which is looped in between the cold water outlet of the hot water tank for the hot water charging circuit and the heat exchanger and that Between the cold water outlet of the hot water tank for the hot water charging circuit and the hot water charging pump, a charging water quantity limiter is inserted, which is set to a predeterminable charging water quantity, then the hot water charging circuit and the circulation circuit are coupled to one another in such a way that the hot water charging pump also as Circulation pump is used.
