Electric underfloor heating insulation advice

[RickyLee53]

Hello,

I'm wanting to run Electric underfloor heating in my kitchen, there are no rads.

The existing floor is concrete. I have 30mm to reach the wooden floor level of the other parts of the house. I was thinking of running 10mm insulation then a 20mm screed, followed by tiles or a wooden floor covering. I'm just worried this will crack with the thin screed. Is there an alternative way? In places the screed might be thinner than 20mm also. But the insulation is pretty dense.

This is what I was looking at, of course I could go thinner on the insulation but it wouldn't work as well.

Thanks for any help.

With so little insulation it'll probably cost a packet to run and the screed will crack in no time. If electric is the only option why not use an electric plinth heater instead? Wickes do them for about £235 through their kitchen dept.
