For the present invention, therefore, the object is to provide a structural unit of the type mentioned, which avoids the disadvantages mentioned above and with the particular simplified manufacturing and accelerated installation of a heating system can be achieved. In addition, a corresponding heating system should be specified.

• - dass die Baueinheit ein längliches, im Einbauzustand gesehen, horizontal verlaufendes Gehäuse aufweist,
• - dass das Gehäuse in seinem Inneren durch eine quer zu seiner Längsrichtung verlaufende Trennwand in eine Heizmediumvorlaufkammer und eine Heizmediumrücklaufkammer unterteilt ist,
• - dass das Gehäuse oberseitig den ersten Vorlaufanschluss in die Heizmediumvorlaufkammer mündend und den ersten Rücklaufanschluss in die Heizmediumrücklaufkammer mündend als vorgefertigte Anschlussstücke aufweist,
• - dass das Gehäuse unterseitig den zweiten Vorlaufanschluss in die Heizmediumvorlaufkammer mündend und den zweiten Rücklaufanschluss in die Heizmediumrücklaufkammer mündend als vorgefertigte Anschlussstücke aufweist und
• - dass die Heizmediumpumpe in den die Heizmediumrücklaufkammer aufweisenden Bereich des Gehäuses integriert ist.

According to the invention, the solution of the first part of the object relating to the construction succeeds with a structural unit of the type mentioned at the outset, which is characterized

• - That the assembly has an elongated, seen in the installed state, horizontally extending housing,
• - That the housing is divided in its interior by a transverse to its longitudinal direction separating wall in a Heizmediumvorlaufkammer and a Heizmediumrücklaufkammer,

Advantageously, in the assembly according to the invention, all parts of a conventional pump group are integrated with a small overall height in the compact executable housing. Since the assembly has two chambers, the fittings for the respective predetermined connection situation both on the side of the heat generator, such as boilers, as well as on the side of the heating circuit manifold or the cascade unit already aligned and arranged during the manufacture of the unit. The unit can therefore be made suitably adapted to the local connection situation in advance and accordingly no effort on rework on site during installation of the heating system is required. It is thus an increased ease of installation compared to the on-site construction, in which all parts must be screwed together on site by hand, achieved.

Preferably, it is further provided for the assembly that the housing has a rectangular cross-section, as seen in the installed state, a height of the housing is greater than a depth of the housing and wherein a length of the housing is at least twice as large as the height of the housing. This contributes to a desirable compact design, while still no disturbing flow resistance for the heating medium are generated. Instead of a rectangular housing cross-section, for example, an oval housing cross-section is possible.

A suitable material for the housing is for example steel.

For the purpose of economical production of the structural unit, the invention also proposes that the longitudinal walls of the housing are formed by a continuous pipe section or two pipe sections arranged one against the other.

So that after installation of the unit in a heating system, the heating medium pump for maintenance or repair purposes still remains easily accessible, the heating medium pump is preferably arranged on or in a, viewed in the installed state, front side longitudinal wall of the housing.

In order to increase the utility of the unit even more, additional fittings can be attached to the housing or mountable or built into the housing or integrated.

In this regard, it is proposed that the additional fittings comprise at least one safety valve and / or at least one filling / emptying valve and / or at least one pressure gauge and / or at least one thermometer.

A preferred embodiment of the assembly provides that the Heizmediumvorlaufkammer and the Heizmediumrücklaufkammer of the housing each have a flow cross section for the heating medium, which is greater by at least a factor of 2 than the flow cross-section of the flow and return ports. In this construction of the chambers occurs due to the cross-sectional enlargements to a flow calming of the heating medium, which entrained in the heating medium air or gas bubbles and / or dirt particles can be easily separated from the heating medium.

For example, be installed in the heating medium return chamber, a magnetic separator are deposited on the magnetizable dirt particles from the heat medium flowing to the heat medium before the dirt particles reach the heat generator and cause damage there.

Alternatively or additionally, a dirt particle sink can be arranged in the heating medium return chamber, in which, supported by reduced heating medium flow rate, heavier dirt particles fall solely by gravity and are thus removed from the heating medium.

In order to be able to easily remove any dirt particles accumulated in the dirt particle sink of the structural unit from the structural unit, it is provided that the dirt particle sink is assigned a blowdown valve.

Also, a vent valve may be arranged as a further fitting on the housing of the assembly.
