Operative devices such as valves, heat meters, thermostats, thermal sensors etc. could be connected to the pipes to set and monitor flows and fluids within the heating station.
  • the object of the present invention is to introduce a heating station that is easier and cheaper to produce, but still is versatile in the sense that it is easily adaptable to individual requirements.
  • a main part of the heating station is a standard produced monolithic unit, it may not be easy to connect such a by-pass.

  • the inner edge (11) operates as end stop for the insertion of the specialized device (25), which in the additional embodiment could be combined with the functional corporation of the specialized device (25), such as being valve seat for a valve.
  • One set of flow paths (3), and the associated set of first couplings (5) may be adapted to connect a heating fluid supply and return to the heat exchanger (2).
  • a set of second flow pats (3), and associated set of first couplings (5) may be adapted to connect a domestic fluid supply and return to the heat exchanger (2).
  • the heating fluid passes one flow path within the heat exchanger (2), often referred to as the primary path, then exchanges heat with the domestic fluid (e.g. water) passing a heat exchanger second (2) flow path, often referred to as the secondary path.
  • the heating fluid has a higher temperature than the domestic fluid.
  • the domestic fluid therefore is heated and can be used either to supply heat to e.g. radiators or floor heating installations, or to water taps or showers.
  • the domestic fluid is being cooled by the heating fluid.
  • first openings (5) are connected to the heat exchanger (2) may be a matter of the design of connected heat exchanger (2). Different first openings (5) could be connected as inlet or outlet to respectively the primary or secondary path if another heat exchanger (2) is connected or it is oriented differently.
