Can I install underfloor heating in combination with insulation screed?

Yes, but not with a wet system like with a screed. An insulation screed is, as the name itself suggests, insulating. The pipes of underfloor heating should never be placed in a material that insulates, but rather in a material that can conduct heat well. Therefore, we recommend a dry underfloor heating system that is installed on top of the insulation screed, or a wet underfloor heating system in a screed.

With tileable insulation screed, the floor finish will always feel a few degrees warmer. This is because there is insulation directly beneath the floor finish. As a result, you actually don't need to install underfloor heating.
