SPC flooring should be installed over underfloor heating only when the flooring supplier approves the particular heating system and installation build-up. Water-based heating and electric heating require their own checks; ordinary plumbing beneath a floor is a separate service-coordination issue.

Confirm compatibility before work begins

Send the flooring specification and heating design to the responsible suppliers. Ask for confirmation covering the floor covering, underlay or adhesive, substrate and control system. Keep the approval with the installation documents. A statement that a product works with heating does not automatically cover every electric mat, heating film or hydronic arrangement.

Check the substrate and concealed services

The installer should assess the substrate using the moisture test method required for that construction. A percentage without a named method is not a usable acceptance limit. Investigate unevenness, cracks and residual construction moisture before covering the surface. Obtain the positions of heating pipes, cables and other services before drilling or fixing thresholds, cabinets or fittings. Protect these services throughout preparation.

Coordinate heating controls and floor covering

Use the approved limits for floor temperature, heating changes and thermal resistance of the installed layers. Thick rugs and other coverings may change local conditions and need review. Ask how the heating system will maintain even operation and how cooling, if present, will avoid condensation. The heating contractor and flooring installer should resolve conflicting instructions before installation starts.

Record commissioning and handover

Follow the approved commissioning sequence rather than applying a universal daily temperature increase. Record substrate results, installation conditions and the heating settings used at handover. Provide the owner with the relevant operating instructions and explain whom to contact if joints open, the floor lifts or hot spots appear. Stop and investigate an abnormal condition instead of increasing heat to dry or flatten the finished floor. This record also helps separate installation issues from equipment faults.
