Definitions

  • the invention relates to an additional heat exchanger for a domestic water heater installed separately from the boiler, connected on the supply and return sides to the boiler, the additional heat exchanger consisting of an internally or externally electrically heated container with flow and return connections.
  • the object of the present invention is to provide an additional heat exchanger for a separate boiler created, connected to the boiler on the supply and return sides to create a hot water heater that can be easily integrated from the outset or retrofitted into a hot water heating system consisting of a boiler and a separate hot water heater and can be operated as a boiler replacement with little control effort the boiler is not in operation, while the additional heat exchanger is to remain uninvolved in the circuit of the heat transfer medium when the boiler is in operation.
  • a container that can be electrically heated from the inside or outside is simply used, but with the proviso that its supply and return connection pipe pieces are connected to so-called passenger pipe pieces, which, in this combination according to the invention, the passage of the heat transfer medium during normal operation, ie with the boiler switched on , take over, but also over sections of the passage of the heat carrier heated in the additional heat exchanger or its return.
  • the additional heat exchanger according to the invention is therefore an additional device which is completely separate from both the boiler and the domestic hot water heater and which can only be appropriately integrated with its two passenger line pieces in the supply and return lines between the boiler and the domestic hot water heater in a suitable manner.
  • the passenger line pieces that are open at both ends are provided with corresponding line connection elements, which can be, for example, flange connections or fitting connections.
  • line connection elements can be, for example, flange connections or fitting connections.
  • the two-way open passenger line pieces can also be fluid-tightly connected to the supply and return lines by welding.
  • the separate supply and return lines between the boiler and the hot water Equipped are, of course, the separate supply and return lines between the boiler and the hot water Equipped with appropriate line connection elements.
  • a circulation pump with a downstream non-return valve is arranged in the flow connection line piece of the additional heat exchanger, and in the other embodiment a three-way valve of known type is provided, which is connected to the flow connection line piece while the other two outlets are integrated in the flow passage pipe section.
  • a circulation pump 7 with a downstream non-return valve 8 is arranged in the flow connection line piece 1.
  • an additional circulation pump 7 'it check valve 8' must be provided in the strand of the flow line 16 outside the additional heat exchanger, which circulation pump 7 'causes the heat transfer medium circulation when the boiler is in operation.
  • the circulation is taken over by the circulating pump 7 belonging to the additional heat exchanger, the non-return valve 8 'belonging to the additional heat exchanger preventing the delivery of the carrier medium heated in the container 4 into the boiler.
  • the non-return valve 8 belonging to the additional heat exchanger prevents the warm heat transfer medium from entering the container 4 when the boiler is in operation.
  • the circulating pump 7 and the check valve 8 are replaced by a simple three-way valve 9 belonging to the additional heat exchanger, which, as shown, is integrated in the line sections 1, 5.
  • a circulation pump 7 'with a check valve 8' in the line of the flow line 16 (as shown) behind the additional heat exchanger.
  • the circulation pump 7 'and the check valve 8' behind the outlet 11 of the three-way valve 9 in the line piece 5.
  • the container 4 is connected in a simple manner to the passenger line piece 6 in a suitable manner by a corresponding return connection line piece 2, as shown.
  • the housing 3 is advantageously formed according to FIG. 3 from a base plate 19 and a removable cover 20, which is provided on both sides with two through openings 21 for the passenger line pieces 5, 6 and the forward and return lines 16, 17 if the passenger line pieces 5 , 6 end with their connecting elements 12 within the shell 20.
