Positioning of bathroom underfloor heating controls

[DaveJS]

I'm at the planning stage of installing a complete replacement bathroom and would like to include electric underfloor heating.
Would appreciate any comments on best places to postion the programmer controller unit and the fused spur isolator. Is it permisable to be inside bathroom - in the zone 3 area, or through the internal wall into what is the hallway? And at what height ?

Unless the circuit you are spurring from has an RCD you will need to fit one, or use a combo RCD/FCU.
Personally I put it outside the bathroom, mostly from a safety standpoint and also as most items dont like wet hands or steamy rooms.

Any height is OK, temp is controlled thru a temp probe in the floor, not air temperature - thats how the controler can go outside.

PS Dont forget Supplementary Equipotential Bonding and that this is notifiable work.

Much appreciate the comments, certainly helps confirm the options I was considering for relocating the interior fittings/hardware.
