Can I install underfloor heating in combination with insulating screed?
Yes, but not with a wet system as with a screed. An insulating screed is, as the name itself suggests, insulating. Underfloor heating pipes must never be placed in a material that insulates, but a material that can transfer heat conduction well. We therefore recommend a dry underfloor heating system that is placed on top of the insulation screed, or a wet underfloor heating system in a screed.
The floor finish will always feel a few degrees warmer due to tileable insulation screed. This is because there is insulation directly under the floor finish. In fact, you do not need to install underfloor heating.
