Heating a dn tiling a 28m2 room

[Giblets46]

Hey there, about to start my second floor tiling job, but this time looking to put down some slate tiles with underfloor heating, room is 28m2 (but then take aaway kitchen cupboards and stuff). My main question is the underfloor heating, as I have existing radiators etc, so just want to take the edge off the floor on those cold mornings, if so, shoudl I go for matts or the loose cable, in which case how much should I get? Looking at these guys:

Have read quotes as high as £1500 (inc insulation), so any other good suppliers would be welcomed!

As for the tiles, slate is a pretty good conductor I understand, so my main worry is making sure that if i get uncalibrated I need to sort them by thickness first? Anything else to look for?
Cheers
Edward

You need to decide on the cost implications with under floor heating.

In the majority of cases ufh is a primary source of heat not a secondary one. You already have radiators - do these heat the room sufficiently?
If so is it really worth it just to take the chill off the tiles?

Perhaps you might consider wood flooring as an alternative or even a pair of those fluffy slippers?!!!!

The decision to use mats or loose wire is down to the layout of the room. Both systems are similar in price. If it is a large square room then go for the mats as they are quicker to fit. If it is an oddly shaped room or has objects to avoid then you would use the loose wire.

I shouldn't really recommend any as I have only fitted out one room so have nothing to compare with but I used WarmUp (Topps tiles) loose wire stuff in my on-suite and had no problems installing it myself (as an amateur) or in the 12 months since. Like yourself I didn't want it to heat the room just to take the chill off the tiles (OK so the wife insisted)

If you can get away with raising the finished height by 10mm then you should put an insulated board down first.
