Cold tails and stat for underfloor heating in same pipe??

[Lillpete]

I'm just chasing in the conduit for underfloor heating (I am only installing the supply and leaving an empty backbox and pipe in the wall for a future date when they install the underfloor heating, I've chewed in one 20mm conduit going down to floor level, will this be ok for the coldtails and stat or will I need a 2nd pipe??

Cheers

Some of the instructions I have seen say put them both in the same conduit but I swear they are written for the septics.

The cables going down can be in the same pipe; but where the floor stat enters the floor, it needs to be in its own bit of pipe (15mm polypipe works well), with the back end taped shut. Allows for removal if it fails.

Most I have installed state they should be in seperate pipes so thats the way I do it. Not to much harder work either.
