Definitions

  • the invention relates to a structural unit for a compact heating system.
  • Such units are state of the art and serve if possible, all fittings of such a heating system to take up space and the necessary channel connections and provide line connections. This is not intended Only a compact design can be achieved, but beyond both the manufacturing and assembly costs and the later Maintenance costs are reduced.
  • From DE 100 07 873 C1 is a structural unit for a compact heating system known, having two heating circuits, one for heating the heating water for central heating and another for heating of the service water.
  • the unit described there is comparatively compact and essentially composed of three injection-molded parts, of which the first centrally located forms the pump housing, formed open to the front for receiving the motor unit is, and the other two on both sides adjoining fitting housing form.
  • the present invention the object of further improving such a unit, in particular to increase the functionality and thus installation and To further simplify maintenance.
  • the invention provides a unit for a compact heating system which rear connections for a plate heat exchanger a central pump housing or pump housing component, connect to the valve housing on both sides, whereby the pump housing for receiving the impeller and for connection the electric motor is designed to be open at the front.
