Travertine With Ufh

[J Sid]

What wattage kit are you fitting?
Is it for feet warming only 100W or 150W wire are you trying to put some heat into the room with a 200W wire?
If the first then no uncoupling membrane is needed imho. 200W then possibly you could but I wouldn't.

This UFH will be 6m2. Decoupling should be on top of that only or for whole area?

If your going to uncouple , then yes the whole area ...

How big is the area ?

15m2 @Dave. 😉

This is living room. Wire around 100W to feet warming mostly in the middle (furniture around).
I hope I can go without uncoupling membrane in that case.

Dave,

You said 10 mm insulattion. Is 6 mm not enough (flat on second floor)?

Imho greg , 10mm gives the best return U-value but if you want 6mm then thats ok , just the heat loss will be more ..

Ok, I understand.

Thank you to all of you.🙂
