Underfloor Heating Installation Supplies

Electric underfloor heating is a system, not a single product: heating mat or cable, insulation board, levelling compound and a thermostat all need to work together.

As an approved ThermoSphere stockist we can specify the correct output, coverage and control for the room you are heating.
