Struggling to make a decision - we are going to install electric underfloor heating mats in our two bathrooms. Just a bit of comfort!
Doing a search I have either DEVImat or Schluter DITRA-HEAT from a UK supplier (tilefixdirect.com) - DEVImat seems a good package, but the Schluter mat comes with a 5.5mm studded uncoupling layer that will give me some sound deadening under the finish of ceramic tiles. If I go with the DEVI I'll need to buy a good quality uncoupling layer, so the cost difference isn't massive ... decisions, decisions!!
Of course, such heating mats are available in France - a local, big DIY store, Leroy Merlin, also offers heating mats - but they aren't a known brand and I think we would be better installing a good quality make. Once it's laid under the tiles I'm hoping it will outlast me!!
Any experience with installing - buying heating mats please??
Thanks, regards, Jonathan

I didn't use any decoupling layer, the cable is within a fairly thick layer of levelling compound laid over 22mm chipboard and with the water tightness layer and ceramic tiles on top. I have never had any issue with impact noise but as is normal here we don't were outdoor shoes indoors.
One area to really look out for is the controller. Ours is a basic one and a total disaster to program. You have to program the whole week day by day with all the various ons and offs and temp settings requiring multiple button presses. I should really change ours but it has not been a priority so I'm afraid I can't give advise on which is the best to go for. Perhaps look for instruction videos on youtube of various models available to you to see which is the easiest for you to program.
The worst is that ours lost all its settings when it was switched off over the summer even though it had power all that time. I couldn't face programming it again so it's been off all this winter. In reality I have rarely missed it. A mat or two in the bathroom takes away 90% of the need.
The tiles have been warm enough the last week that I would be turning off the heat to them now anyway.
My advise would be to not expend too much time or money on this, but do take a little care with choosing the controls. Unless you are very cold blooded you are unlikely to have it on for more than a few hours a day for 3 to 4 months a year.
