Radiant Heated Floors Under Tile, Explained

How electric mats and cables warm a tile floor, what a thermostat and sensor do and what to plan before tile is set.

Radiant heat under tile uses a thin electric mat or cable set in the layer under the tile. A thermostat with a floor sensor controls the temperature, and a qualified electrician connects the system to power. Because tile conducts heat well, the floor warms evenly and the room feels comfortable at a lower air temperature. Heat is most often added in bathrooms, kitchens and entries.

The key is planning. Heat has to go in before tile, mapped around fixtures so it warms where you stand and not under cabinets. The system is tested before and after tile is set, and the floor is prepared to protect the wiring. Homeowners in Nashville usually choose heat when they are already replacing the floor, because it is a modest addition at that stage. We coordinate with your electrician and explain how to use the controls.
