Electric UFH taking up badly laid tiles, and levelling - Tile Advice

[Doggit]

There's no real place for this thread, so here goes.

The house was built 1930 (by gerry builders) and has a 4" aggregate floor in the kithen, and seems to have a painted DPM about half inch below the floor level, then a light screed of sorts before the tiles were laid, and then the last owners laid a new set of tiles on top of them.

The current owner wants Porcelain tiles for durability, and although they have central heating, the existing floor is always cold in the winter, so they were wondering about an electric mat should to take the edge off.

Suggestions how to handle this project please guys.

Me personally I get someone who knows that area of expertise, there are so many issues which need to addressed IMO.

Sounds like you want to be starting again from ground level. I'd personally go for wet underfloor heating if the boiler has the capacity but, as Whitebeam says, it'll be more than a tiling job

• The boiler doesn't have the extra capacity, but they're only looking to take the chill off of the floor, not for heating the room. I've no problem taking up both sets of old tile, and a 100W/sqm will warm the floor up, I suppose my initial question is how best to level the floor, and get the dpm in it. Do I need to level the floor first, then apply the DPM, then re-level, or are there other ways of doing it.

Ultra level2 can be used under a dpm but only goes to 10mm thick.
