UFH on concrete, topped with porcelain tiles

[2db]

Hi all,

Been doing lots of digging around for information on this forum and there's lots of v useful advice (thanks to all!)

We already have central heating in the kitchen and am only interested in electric UFH purely to take the edge off the cold tiles on the odd occasion during winter months.

Given that the kitchen is about to be ripped out and replaced, we're contemplating putting in a basic electric UFH system onto the concrete floor - same old problem with levels. We'd really prefer not to increase the levels and are contemplating just putting the UFH straight onto the concrete floor (well, ok, there's a skim of self levelling compound there on top of the concrete.) without insulation boards.

Given the intentions of limited use (so running costs is not really an issue for us) - is such an installation likely (~150W/m2) to work effectively enough to just take the edge off cold tiles for an hour or so in the morning and a couple of hours in the evening? (the floor space to cover is UFH only 7m2)

The screed will take a lot of heating before it reachs your tiles.

Yes it will work, the tiles will take longer to heat up though

I would at the very least use 6mm insulation, as without it you will need to have it running for quite a long time before it reaches a suitable temperature.

would advise slc over ufh wires better suface to tile to and also protects wires from damage during installation

i agree with stewart wothout insulation boards of some sort it may take upto 30mins for your floorto warm up on theupside though it takes longer to cool down so the heating can be turned off earlier saving you money in that respect
