Electric underfloor heating fixing methods

[sparkyork]

Hi all, not posted for a while so her goes...

tomorrow im installing 30m sq of loose electric underfloor heating cable.

im not new to installing the stuff but do much prefer the matt style system.

With it been such a big area I want to make sure it doesn't start lifting when it's sat for a few days before it gets self levelled over the top.

I've got a ck telecoms cable style staple gun and I'm thinking do using this as it's into tile backer board so shouldn't squeeze to hard on the cable, and I'd consider ufh cable to be stronger than bt cable?

thoughts or experiences appreciated

cheers

Looks pretty good, however it's getting laid tomorrow so not an option unfortunately

Double sided carpet tape then heating wire then scrim tape over the top is how I normally do it

don't use staples!. seen a plumber do that on 2 jobs. both failed within 6 months.

Cheers chaps I'll stick to tape then, couldn't get hold of any staples anyway lol

The advantage of scrim tape is that the self levelling compound will penetrate it and surround the cable properly, in theory you could get air pockets either side of the cable where other tapes are used. I haven't a clue whether this will really be a problem or not, but I don't chance it.

Wot!!! ............ No Gaffer Tape???? mg_smile:

It's not that much different to gaffering half a dozen microphone leads across a stage really. :happy:
