Tiling Query

[farlo]

Hi fellow tilers, just after some advice.....
I've been asked to quote for tiling a conservatory, it is currently tiled but the customer wants underfloor heating putting in and then tiling over.
Never done the underfloor heating before....am I best removing the existing tiles, laying the underfloor heating and then tiling over the top?
Any tips would be appreciated.
Cheers
Rob

I would have thought alot of the heat would be lost going over tiles, not sure though. I would prefer to take up, clean, level, then continue as per usual.

i know im just bein presumptuous, but as its gettin bloomin cold again they obviously want a nice warm floor and with it being so cold now i bet they'll switch the heating on even tho you tell them not to for 30 days etc which will most likely mean they'll deny turning it on atall or too high too soon and expect you to redo it.

not saying they will... but meh, situations like this put me off installing underfloor heatng systems

I asked Warmup for tech advice re this same thing. They said as long as tiles are sound underneath, then 6mm warmup boards glued onto the old tiles would be a great insulation bed for a new install. I did this and had good results!

Why 30 days..?..

seem to remember some people saying turn it up 1 degree a day and someone else saying just be on the safe side and not turn it on for a month

Hi...yea i've mentioned to the customer that they musn't just wack the heating on full blast....they've assusred me they won't....let's hope they don't!

Hi, thanks for the advice, i've mentioned putting down Ekoboard to the customer but they're not too bothered....i've try and convince them otherwise...for the minimal extra cost I think they should def but put down first.
Thanks again
