Definitions

  • the present invention relates to a water heating system for providing heated fresh water, the water heating system having a buffer storage tank and a heat source and a fresh water circulation line and a fresh water heat exchanger, and the buffer storage tank having an outer wall of the storage tank and a storage cavity surrounded by the outer wall of the storage tank, and the heat source for heating a heat transfer fluid in the
  • the storage cavity is connected to the buffer storage tank and the fresh water heat exchanger is arranged in the storage cavity, the fresh water heat exchanger having a cold water inlet for connection to a drinking water supply line and a circulation water inlet and a hot water outlet, the fresh water circulation line having a circulation flow line connected to the hot water outlet and a circulation flow line connected to the circulation water inlet , Has circulation return line.
  • Such water heating systems are in the prior art, for example from the DE 10 2013 112 952 A1 known. With them it is provided that the heat transfer fluid heated by a heat source in the storage cavity of the buffer storage tank fresh water in the Fresh water heat exchanger heated. The fresh water is then made available for withdrawal in a fresh water circulation line. Buffer storage tank, in which a heat exchanger is arranged in the storage cavity, for example in AT 516 383 B1 shown. Another water heating system is from the CH 706 516 A1 known.
  • Fresh water circulation lines are now common in hot water preparation systems in order to ensure that warm fresh water is always available at the desired temperature at a withdrawal point for warm fresh water right at the start of the withdrawal process.
  • the heated fresh water is circulated in the fresh water circulation lines.
  • the object of the invention is to improve a water heating system of the type mentioned above in such a way that it can be used to ensure particularly well that no pathogens and in particular legionella can form in the fresh water heat exchanger.
  • this is achieved in a water heating system of the type mentioned above in that the water heating system has a flushing line which connects the circulation flow line or the circulation return line to a flushing line connection of the fresh water heat exchanger.
  • the flushing line which is designed in addition to the fresh water circulation line, it is possible and correspondingly strong heated or heated fresh water from the circulation flow line or the circulation return line via the flushing line connection in the fresh water heat exchanger, so that the areas of the fresh water heat exchanger can be flushed with correspondingly high-temperature fresh water in which, in a normal operating mode, only relatively cold or to kill the pathogens still there is insufficiently heated fresh water.
  • the flushing line connection is formed directly at the cold water inlet in the fresh water heat exchanger.
  • the cold water inlet is formed in an area between the flushing line connection and the circulation water inlet in the fresh water heat exchanger. Both variants ensure that the entire relevant section of the fresh water heat exchanger, in particular its entire low-temperature zone, can be flushed through with the correspondingly hot fresh water from the fresh water circulation line introduced via the flushing line and the flushing line connection.
  • the heat source is connected to the buffer tank in such a way that temperature stratification is formed in the heat transfer fluid, with the heat transfer fluid having a lower temperature being located in a lower, low-temperature zone of the storage cavity. This low-temperature zone then gradually transitions into an overlying high-temperature zone, in which the heat transfer fluid is correspondingly heated or cooled. is heated.
  • Water can be used as the heat transfer fluid, optionally with the additives customary in heating systems or hot water preparation systems. However, it can also be another suitable heat transfer fluid or a mixture of several heat transfer fluids.
  • the buffer storage container can therefore be connected to one, but also to several, in particular several different, heat sources for heating or for heating the heat transfer fluid.
  • the water heating system according to the invention can be designed in such a way that it only serves to provide heated fresh water.
  • the heat transfer fluid in the storage cavity can be used not only for heating the fresh water but also for operating heating circuits such as underfloor heating, wall heating, ceiling heating or radiator heating.
  • the water heating system according to the invention can therefore also be designed as a heating system with which not only heated fresh water can be provided, but also a building with corresponding heating circuits is heated.
  • the heated fresh water is taken from the fresh water circulation line and must be refilled again and again into the fresh water heat exchanger via the drinking water supply line and the cold water inlet.
  • Fresh water circulation lines with a corresponding circulation flow line and a corresponding circulation return line are known per se.
  • at least one pump is integrated into such a fresh water circulation line in order to circulate the heated or correspondingly heated fresh water in the fresh water circulation line.
  • a wide variety of extraction devices for extracting the fresh water from the fresh water circulation line are also known. For example, it can be a simple hot water tap, a mixer tap or the like.
  • the storage cavity has a volume of at least 500 liters, particularly preferably at least 900 liters.
  • Preferred variants of the invention provide that a lockable valve is arranged in the flushing line or between the flushing line and the circulation flow line or between the flushing line and the circulation return line. It is also favorable if in the flushing line and/or a pump is arranged in the fresh water circulation line, preferably in the circulation return line. With the appropriate pump, the necessary pressure for moving the fresh water can be provided both in the fresh water circulation line and in the flushing line. With an appropriately switchable pump and/or at least one appropriately lockable valve, however, it is also possible to use the flushing line only intermittently, i.e. from time to time, for flushing the fresh water heat exchanger with correspondingly strongly heated or heated fresh water.
  • the fresh water heat exchanger is in thermally conductive contact with the heat transfer fluid in the storage cavity, so that the fresh water in the fresh water heat exchanger is heated by the heat transfer fluid.
  • the fresh water heat exchanger is particularly preferably a heat exchanger line which is vertical in the storage cavity and is at least partially helical, or in other words helical.
  • plate heat exchangers known per se as corresponding fresh water heat exchangers.
  • the vertical extent of the fresh water heat exchanger is at least 75%, preferably at least 80%, of the vertical extent of the storage cavity. As a result, essentially the entire temperature spread in the heat transfer fluid in the storage cavity can be used to heat the fresh water in the fresh water heat exchanger.
  • An inventive method for operating a water heating system provides that in a normal operating mode cold fresh water from the drinking water supply line in the fresh water heat exchanger by means of Heat transfer fluid is heated and circulated in the heated state in the fresh water circulation line and in a rinsing mode the heated fresh water is introduced from the circulation flow line or the circulation return line via the rinsing line and the rinsing line connection into the fresh water heat exchanger and passed through the fresh water heat exchanger.
  • the flushing line is only activated in the flushing mode. It is not active in normal operating mode.
  • the flushing mode can be activated at predetermined time intervals, for example every four hours. It is also conceivable for the time intervals to be regulated as a function of the fresh water withdrawal.
  • Such an intermittent operation of the flushing line also has the particular advantage that the temperature stratification formed in the heat transfer fluid in the storage cavity is not or only slightly disturbed by the flushing operating mode.
