Definitions

  • the invention is based on a water heater according to the Genus of the main claim.
  • a water heater according to the Genus of the main claim.
  • possible cover of the fins unoccupied flow cross-section results in a high Efficiency of heat transfer, however, the Exhaust gas temperature is correspondingly low.
  • the one with the Arrangement of the aperture created the Flow cross-section by releasing the lamella-free Extending the range can increase the exhaust gas temperature and the formation of condensed water can be safely avoided.
  • the arrangement according to the invention with the features of The main claim has the advantage that a customary Standard heating device without structural changes those available in different applications Special features and conditions simplified and as required adapted by using plug-in parts of different lengths can be.
  • a secure hold of the insert in the gap and one perfect coverage results when the plug part is U-shaped is bent sheet metal part, the legs in Insert position resilient on the combustion chamber wall and on the Slats rest, and if one leg with one shoulder is provided to limit the insertion depth.
  • FIG. 1 shows a parallel to the slats of the heat exchanger through the cut output side of the combustion chamber of a gas-heated Water heater
  • Figure 2 if necessary in the Water heater according to Figure 1 insertable part in Side view
  • Figure 3 shows the water heater of Figure 1 with the plug-in part used.
  • the water heater has one not shown Gas burner a combustion chamber 10, in the output side Heat exchanger 12 is used. This has a block from parallel arranged lamellae 14, which by Pipes 16 are penetrated, which the water to be heated to lead. Downstream of the heat exchanger 12 is a collecting hood 18 arranged for the exhaust gas to be removed.
  • a gap 22 of a defined width provided that in the uncovered state according to FIG. 1 a flow cross section not occupied by fins for forms the combustion gas.
  • the one through this Flow cross section passing through without cooling The proportion of combustion gas raises the exhaust gas temperature so far that even under unfavorable operating conditions a failure of condensate is avoided.
  • this advantage must by a slight reduction in the efficiency of the Heat transfer can be bought.
  • a plug-in part 24 is provided which in the gap 22 can be used and closes it.
  • the Plug-in part 24 is a substantially U-shaped Sheet metal part with two legs 26, 28 and a web 30 educated.
  • the leg 26 lies in the inserted position resilient on the front wall 20 of the combustion chamber 10 and the Leg 28 resiliently on the end edges of the slats 14.
  • the leg 28 is included provided a shoulder 32, which is on the slats 14th touches down when the plug part 24 is in the prescribed position has reached.
