Two boilers

[cliffed]

Not having much imfo from plumbers on site,they are installing 2 boilers remote from a large house.Its a s plan/ufh system/ hot water,3 manifold positions,being an electrician wondering bout isolation,at manifolds & boiler positions,not as simple as it sounds,ie regarding control cabling,could have 1 isolation switch at remote end by boilers but just wondering what you think cheers

You could install one isolation switch for the whole system and then a 3 pole switch next to each boiler so they can be isolated separately if required.
