Abstract

Die vorliegende Erfindung betrifft eine Heizeinrichtung (1) zum Beheizen eines Warmwasserkreises (7), insbesondere einer Warmwasserversorgungsanlage eines Gebäudes,

  • mit einem ersten Wärmeübertrager (4), der von der Heizeinrichtung (1) erzeugte Wärme auf einen Kopplungsflüssigkeitskreis (5) überträgt,
  • mit einem zweiten Wärmeübertrager (6), der den Kopplungsflüssigkeitskreis (5) wärmeübertragend mit dem Warmwasserkreis (7) koppelt,
  • mit einem ersten Temperatursensor (15), der eine im Kopplungsflüssigkeitskreis (5) an einem Einlass (16) des zweiten Wärmeübertragers (6) herrschende erste Temperatur (t1) mißt,
  • mit einem zweiten Temperatursensor (17), der eine im Kopplungsflüssigkeitskreis (5) an einem Auslaß (18) des zweiten Wärmeübertragers (6) herrschende zweite Temperatur (t2) mißt,
  • mit einer Steuerung (21), die mit dem ersten Temperatursensor (15) und mit dem zweiten Temperatursensor (17) verbunden ist, anhand der ersten Temperatur (t1) und der zweiten Temperatur (t2) einen aktuellen Wärmebedarf des Warmwasserkreises (7) ermittelt und in Abhängigkeit dieses Wärmebedarfs die Heizeinrichtung (1) betätigt.

The present invention relates to a heating device (1) for heating a hot water circuit (7), in particular a hot water supply system of a building,
  • with a first heat exchanger (4) which transfers heat generated by the heating device (1) to a coupling liquid circuit (5),
  • with a second heat exchanger (6) which couples the coupling liquid circuit (5) in a heat-transmitting manner to the hot water circuit (7),
  • with a first temperature sensor (15) which measures a first temperature (t 1 ) prevailing in the coupling fluid circuit (5) at an inlet (16) of the second heat exchanger (6),
  • with a second temperature sensor (17) which measures a second temperature (t 2 ) prevailing in the coupling fluid circuit (5) at an outlet (18) of the second heat exchanger (6),
  • with a control (21), which is connected to the first temperature sensor (15) and to the second temperature sensor (17), based on the first temperature (t 1 ) and the second temperature (t 2 ) a current heat demand of the hot water circuit (7) determined and depending on this heat demand, the heater (1) operated.
