Hi, first im gas safe registered so know a bit about wiring but my own boiler is giving me a head ache. Worcester greenstar heatslave 18 25 oil i fitted a nest just linked ch from boiler demand to programmer demand all good. I now want to wire in another stat for my ufh but dont know what to use for switched live

I know little about wiring, but I would have thought x2 zone valves, one for main heating and one for ufh, then switched lives on orange?

Heating needs s planning unless you’ve used an old rad feed for the ufh which is a no no
