Heating circuit manifold in Combination with Pump Groups

The heating circuit manifold-distributor in a system with pump groups plays a very important role – it combines the functions of a hydraulic coupling and a heating circuit distributor.

Main tasks of the distributor:-manifold

• Hydraulic separation of the heat source circuit (e.g., boiler, heat pump, or fireplace) from the heating circuits (e.g., underfloor heating, radiators) – thanks to this, the pumps in the pump groups can operate independently of the boiler pump.
• With the Nordic Tec 2-4 distributor, you can actually connect up to 2 heat sources – which will have independent pump circuits and will not negatively affect each other in terms of pressure.
• Flow stabilization – prevents flow disturbances in the system that could arise due to differences in pump performance across various circuits.
• Distributing supply to multiple heating circuits (in this case, 2 or 3) – the distributor has the appropriate number of output connections (e.g., 2, 3, or 4), to which you can connect pump groups. Everything is visible in the attached product photos.

When Should a Pump Group Distributor Be Used?

The coupling-distributor is typically used in heating systems where there is:

• Multiple heating circuits, but also, for example, a clear temperature separation between heating (CH) and domestic hot water (DHW) (as in buildings with underfloor heating).
• Varied supply temperatures – meaning two cooperating heating systems within one building (e.g., radiators and underfloor heating).
• A need for hydraulic separation (the reasons may vary, e.g., a large building or a multi-story building).
