I am having a new conservatory built and am intending having electric underfloor electric heating.
My builder has described the electric heating pads (not sure what system yet) being installated as being on top of 100mm of insulation covered by the concrete base which is then tiled.
Is it advisable to install in this way for a new build?
Most of the commercial websites describe the installation of systems into existing rooms so the insulation goes on top of the existing concrete base followed by the electric pads then the tiles
