Hi all, I am currently re-wiring a large 6 bed manor house as part of an overall refurb.
The plumber landed me with a bombshell today when he told me that he knows nothing about the electrics for the existing boiler or the new UFH system.. So yours truly has an extra job.
Only just started to look at it so I may not have all required info yet. I have not been able to speak to the person who specified the kit/design yet but I wanted to get a head start if possible.
1X 7 port (pumped) manifold feeding 5 zones.
1X 7 port (pumped manifold) feeding 4 zones.
1X 6 port (pumped) manifold feeding 4 zones.
1X 3 port (pumped) manifold feeding 2 zones.
The UFH kit appears to contain a master 4 zone wiring centre plus 2X 6 zone slave wiring centre which attach to the master. This appears to cover the number of zones (15) with one to spare.
Two questions:
1) I thought wet UFH systems traditionally have a wiring centre per manifold? Yet this kit seems to have one large wiring centre for the whole thing.
If that is true then I will need to run many (many) wires from room stats/pumps/actuators from all over the house to the one wiring centre. Does that sound right?
2) If my assumption is wrong (maybe all the kit parts have not arrived yet) Assuming there is one wiring centre per manifold then what do I do regarding the boiler signal (I know I will need to use the volt-free contact)
Do I daisy chain all the volt free contacts of all wiring centres together and then run a single twin+earth back to the boiler?
Obviously any zone will call for heat at any time so I assume I would need to link them all together (in paralell) at some point?
Additional info:
All rads are being removed.
There is a megaflow hot storage tank which will stay.
The original water circuit appears to be S-Plus scheme.
Thanks for any enlightenment
