Manifold use for radiator central heating system

[AFH01]

Afternoon,

Any advice/guidance would be appreciated. We are completing renovating & extending an old property which will include a full re-plumb & rewire. At current property uses a solid fuel burner to heat water (ancient) and wiring has enough C1's & C2's to justify ripping everything out and starting again.

We are looking at getting a new combi-boiler installed which will then feed the CH via 2 manifolds, one for old property (total approx 100m2), 1 for new extension (total approx. 150m2); each centrally located in their respective area. Each manifold will then feed 6 zones across 2 floors with actuators on the manifold connected with the stats in each of the zones. Feeds of 22mm to manifold and then 15mm or 10mm to rads depending on flow calcs.

I am unsure what the wiring centre near the manifold would need to be and also would the individual wiring centres both be able to connect back to the boiler? I have looked into Heatmiser systems which indicate yes, but these seem to be predominantly focused on UFH as opposed to rad focused. What would the electrical set up need to be to go from manifold back to boiler?

Thanks in advance.

The manifold itself doesn't know what it's connected to so no need to worry if they're primarily for UFH. If you want to use actuators managed by their own zone stats on a centralised manifold then you'll also need a control centre and a system that would be used for an UFH setup could easily be adapted to run multiple rads over multiple zones without issue.

Of course traditionally that would all usually be controlled by 2 port valves and the zone stats control the 2 ports and they control the boiler switching but no reason not to use an UFH setup. It can all be wireless too with the boiler being switched by the control centre either through a switched live via a wiring centre or wirelessly through a RF switch.
