Definitions

  • the invention relates to a water heater according to the preamble of claim 1.
  • a generic water heater is for example from the DE 100 32 714 A1 known.
  • the primary circuit of the heat exchanger is connected to the Bankbullvorlauf and Schumacherschreiblauf.
  • the heating water return is additionally connected to a mixing valve. This serves to avoid overheating of the hot water.
  • the hot water temperature is usually controlled thermostatically.
  • such a heat exchanger is connected to a stratified storage tank for buffering. It is essential that the stratification in the memory during the preparation of the hot water is disturbed as little as possible.
  • the invention is therefore based on the object, in particular in conjunction with a buffer memory to optimize the hot water preparation via a heat exchanger.
  • the water heater is characterized in that in the hot water drain line, a hot water mixer is arranged, whose connection is connected to a source of water whose temperature is lower than that of the hot water drain line, and that the secondary circuit is provided with at least one intermediate connection, which Source of water is used, whose temperature is lower than that of the hot water drain line.
  • the secondary circuit of the heat exchanger is interrupted, so that the entire volume flow of the cold water is first preheated in the first, lower part of the heat exchanger and only then is available for mixing the hot water mixer.
  • the control quality is optimized and parallel to the heat exchanger is operated load-dependent, because the hot water flow rate in the upper part of the heat exchanger varies. There are less effects on the hot water temperature at the outlet due to the inertia of the heat exchanger, as the heat exchanger volume flow components are withdrawn.
  • a heat exchanger with at least one intermediate connection in the secondary circuit is provided on this heat exchanger.
  • the same function can also be achieved with a second embodiment by connecting at least two heat exchangers in series.
  • the at least one intermediate connection in the primary circuit and / or the at least one intermediate connection tapped in the secondary circuit between the two heat exchangers can be connected on a connecting line or on a fitting for connecting the two heat exchangers.
  • To the intermediate port in the secondary circuit can also be connected to a circulation line with its own circulation pump, which then serves as a source of water for the secondary-side hot water mixer whose temperature is lower than that in the hot water drain line.
  • a circulation line with its own circulation pump which then serves as a source of water for the secondary-side hot water mixer whose temperature is lower than that in the hot water drain line.
  • the mixing valve in the primary circuit of the heat exchanger can be coupled to the hot water mixer in the secondary circuit and be provided with a common adjusting device, which is arranged centrally, for example, and acts on both sides.
  • a common adjusting device which is arranged centrally, for example, and acts on both sides.
  • the hot water preparation is optimized via a heat exchanger.
  • the temperature level of the hot water remains very even.
  • the return temperature on the primary side is reduced since, in contrast to other known arrangements, a maximum volume flow is now available in the lower part of a heat exchanger or in the second heat exchanger. In known arrangements, the volume flow in this area would be reduced on the primary side.
  • the lowest return temperature for the current operating state is always applied to the return connection of a primary-side connected memory so that optimization of the overall system can be achieved, for example because the stratification in the memory is retained or because solar heat is transferred to a low temperature level in the lower region of the memory can.
  • the water heater consists essentially of a heat exchanger 1 or in a series circuit of yet another heat exchanger 2. Their primary circuit is connected to a heating water supply line 3 and a heating water return line 4. In this case, a controlled by a temperature sensor 5 mixing valve 6 and a pump 7 is arranged in the heating water supply line 3. The temperature sensor 5 is located in the hot water drain line 8 in the secondary circuit, which still has a cold water supply line 9.
  • the primary circuit is provided with at least one intermediate connection 10, which leads from the central region of a heat exchanger 1, or starting from the connection region between the series-connected heat exchangers 1 and 2, to the mixing valve 6. Via this intermediate connection 10, water whose temperature is below that in the heating water supply line 3 passes to the mixing valve 6.
  • a hot water mixer 11 is installed, which is connected to a further intermediate connection 12.
  • This intermediate connection 12 in the secondary circuit also leads from the middle but secondary side region of a heat exchanger 1, or starting from the connection region between the series-connected heat exchangers 1 and 2, to the hot water mixer 11. Via this intermediate connection 12, water passes whose temperature is lower than that in the hot water mixer. Drain line 8 is to the hot water mixer 11th
