Abstract

Es wird ein Heizgerät zur Raumheizung und Brauchwasserbereitung sowie ein Verfahren zum Betrieben des Heizgerätes vorgeschlagen. Das Heizgerät weist einen von einer Wärmequelle (10) beheizten Primärwärmetauscher (11) auf, der an einen geräteinternen Heizkreis (12) angeschlossen ist, in dem von einer Umwälzpumpe (13) angetrieben mittels des Primärwärmetauschers (11) erwärmtes Heizwasser zirkuliert. Weiterhin verfügt das Heizgerät über einen Sekundärwärmetauscher (20), an dessen Primärseite ein geräteinterner Brauchwasserkreis (18) und an dessen Sekundärseite eine Brauchwasserleitung (21) angeschlossen ist. Von einer Steuerung (30), die ein Umschaltventil (14) ansteuert, wird der interne Heizkreis (12) wahlweise in einem Heizbetrieb mit einem externen Heizungskreis (17) oder in einem Brauchwasserbetrieb mit dem geräteinternen Brauchwasserkreis (18) verbunden. Die Steuerung (30) verfügt über einen Algorithmus, der auf Mittel zur Einstellung des Massenstroms im geräteinternen Heizkreis (12) derart einwirkt, dass der im Brauchwasserbetrieb über den Primärwärmetauscher (11) strömende Massenstrom des Heizwassers in Abhängigkeit von der Temperatur des Brauchwassers verändert wird.

It is proposed a heater for space heating and dhw heating and a method for operating the heater. The heater has a primary heat exchanger (11) heated by a heat source (10), which is connected to a device-internal heating circuit (12) in which heating water heated by a circulating pump (13) circulates by means of the primary heat exchanger (11). Furthermore, the heater has a secondary heat exchanger (20), on the primary side of a device-internal hot water circuit (18) and on the secondary side of a hot water line (21) is connected. From a controller (30), which controls a changeover valve (14), the internal heating circuit (12) is selectively connected in a heating operation with an external heating circuit (17) or in a service water operation with the device-internal hot water circuit (18). The controller (30) has an algorithm which acts on means for adjusting the mass flow in the device-internal heating circuit (12) such that the mass flow of the heating water flowing in the service water via the primary heat exchanger (11) is changed depending on the temperature of the service water.
