Abstract

Die Erfindung betrifft ein Verfahren zum Betrieb einer Trinkwarmwasser-Bereitstellungsvorrichtung nach dem Durchflussprinzip mit einem Wärmetauscher, der einen ersten Durchflusskanal für zu erwärmendes Trinkwasser und einen zweiten Durchflusskanal für ein von einer Wärmequelle zu erwärmendes Heizfluid aufweist. Der erste Durchflusskanal ist über eine Zuleitung mit einem Trinkkaltwasseranschluss und über eine Ableitung mit einem Trinkwarmwasserabnehmer verbunden, wobei die Zuleitung und die Ableitung über eine Zirkulationsleitung mit einer aktivierbaren Zirkulationspumpe verbunden sind. Ein Heizprogramm und ein Ruheprogramm der Wärmequelle wechseln phasenweise und in Abhängigkeit eines Nutzerverhaltens ab. Bei aktiviertem Heizprogramm erwärmt die aktivierte Wärmequelle das Heizfluid und durch den ersten Durchflusskanal geleitetes Trinkwasser wird mittels des Heizfluids erwärmt. Bei aktiviertem Ruheprogramm liefert die deaktivierte Wärmequelle keine Wärme und es wird kein Wasser zum Wasserabnehmer geleitet. Verfahrensgemäß werden die Aktivierungszeitpunkte des Ruheprogramms erfasst und derart verwertet, dass bei Vorliegen eines Aktivierungszeitpunkts das Ruheprogramm mit einem Nachlauf eingeleitet wird, bei dem die Zirkulationspumpe aktiviert sowie Wasser durch die Zirkulationsleitung und den ersten Durchflusskanal im Kreis gefördert wird.

The invention relates to a method for operating a hot water supply device according to the flow principle with a heat exchanger having a first flow channel for drinking water to be heated and a second flow channel for a to be heated by a heat source heating fluid. The first flow channel is connected via a supply line with a drinking cold water connection and via a discharge with a domestic hot water collector, wherein the supply line and the discharge line are connected via a circulation line with an activatable circulation pump. A heating program and a rest program of the heat source alternate phase-wise and depending on user behavior. When the heating program is activated, the activated heat source heats the heating fluid and drinking water directed through the first flow channel is heated by means of the heating fluid. When the sleep program is activated, the deactivated heat source does not provide heat and no water is supplied to the water collector. According to the method, the activation times of the rest program are detected and utilized such that, when an activation time, the rest program is initiated with a wake, in which activates the circulation pump and water is circulated through the circulation line and the first flow channel.
