Under-tile mat or loose cable: which one?

Under-tile mat or loose cable: which one?

Mats and cables both deliver heat under tiles. Which one suits depends on your room and your installer.

Heating mats

A mat is a heating cable already fixed to a mesh at a set spacing, so the output per square metre is fixed. Roll it out, cut the mesh (never the cable) to turn at walls, and tile over it.

  • Fastest install in square and rectangular rooms
  • Output fixed at 150 or 200 W/m²
  • Minimal build-up height

Loose cable

A cable is fixed to the floor with fixing strips at whatever spacing gives the output you want. It takes longer but fits any shape.

  • Fits irregular rooms and around fixtures
  • Output set by cable spacing
  • Suits screed and slab installations as well as under tile
Either way: test the insulation resistance and conductor resistance before, during and after tiling, and record the results for the warranty.

Our advice

For most bathrooms a mat is quicker. For kitchens, L-shaped rooms and larger areas with cabinetry, cable often gives better coverage. Send us a floor plan and we'll lay it out for you.
