Description
The Thermowire Undertile Heating Cable is a traditional loose-wire electric underfloor heating system, designed to be installed directly below tiles. Its slim profile allows the cable to sit within the tile adhesive layer, meaning no extra height is added to your floor build-up.
Ideal for bathrooms, kitchens, and small or awkward-shaped rooms, Thermowire delivers consistent, comfortable radiant heating while fitting seamlessly around fixtures and tight spaces.
