Definitions

  • the invention relates to a compact heating system according to the features specified in the preamble of claim 1.
  • Compact heating systems of this type are used for heating domestic hot water, ie for hot water on the one hand and for heating heating water on the other.
  • the water is guided in a heating circuit, in which it is heated in a primary heat exchanger and circulated by a pump through the heating circuit for space heating.
  • the heating circuit for space heating is switched off, if necessary by means of a switching valve and instead switched on a heating circuit for water heating, which has a secondary heat exchanger in which the hot water is heated.
  • pump and changeover valve known, for example, in EP 0 825 387 B1 are shown by way of example and schematically.
  • the EP 0 825 387 B1 shows as well as the EP 1 031 795 A the preamble of claim 1.

  • the invention has for its object to provide a generic compact heating system, which is aerodynamically and manufacturing technology favorable and which allows a compact design.
  • the basic idea of the present invention is to connect the discharge nozzle of the pump directly to the adjacently arranged valve housing in order thereby to create, on the one hand, a streamlined transition between the pump and the valve housing and, on the other hand, a compact structural unit. Because no piping between these components takes place, results in a compact and stable assembly, in particular, when the pump housing and the valve housing are integrally formed.
  • the use of a directional control valve in the immediate vicinity of the pump is advantageous, since stable and largely flow-independent switching operations can be ensured over a long period of time.
  • the directional control valve is in particular also insensitive to contamination or deposits.
  • the valve housing is formed so that it has a rear connection pair, which can be connected directly to the secondary heat exchanger, which is usually designed in the form of a plate heat exchanger.

  • the connection unit can be designed either as a separate component or preferably integrally with the assembly, so that all four connections of the plate heat exchanger are directly connected to the unit. In addition to the compact construction, this results in particular in a stability advantage, since the plate heat exchanger then forms a stabilizing base for the assembly.
  • connection stub is understood to mean an opening which can be connected in a suitable manner to a pipe or other component. It does not necessarily have to be a threaded connector, but can also be any other connection component of such a connection.
  • the side-by-side, down-to-back position makes it easy to connect external lines and make them easy to access.
