Most vinyl floors work over underfloor heating — provided the temperature is controlled and the subfloor is right.
Know the temperature limit
Surface temperature should not exceed 27°C. Above that, the adhesive and the core can both be affected, and any movement shows at the joints.
Commission the system before fitting
Run the heating for at least a week before installation, then bring it down to room temperature 48 hours beforehand. This drives residual moisture out of the screed.
SPC is the safer choice
Its stone-composite core is dimensionally stable, so it expands and contracts less than flexible vinyl as the system cycles through the day.
