The short answer

Heating film goes under floating floors (laminate, vinyl, engineered wood). Heating mat goes under tiles (ceramic, porcelain, natural stone). The floor type determines the system — there's no overlap, and trying to use the wrong system for your floor type will lead to problems.

Heating mat — the tile specialist

A heating mat is a resistive cable embedded in a fibreglass mesh. The mat is embedded in tile adhesive before tiling — the cable becomes part of the tile structure. When switched on, the cable heats the adhesive and tile above it.

Key characteristics:

  • Thickness: 3–4mm (adds to floor height)
  • Installation: embedded in tile adhesive — permanent
  • Compatible with: ceramic, porcelain, natural stone, concrete
  • Not compatible with: floating floors (laminate, vinyl, engineered wood)
  • Heat-up time: 20–40 minutes (tile has high thermal mass)
  • Typical output: 150–200W/m²
  • Lifespan: 25–40 years
  • Cost: €18–€35/m² for mat only; €55–€75/m² fully installed

Heating film — the laminate specialist

Heating film is a layer of carbon ink printed between two polyester films. It generates infrared heat — electromagnetic radiation that heats objects directly rather than heating air. The film lies flat under a floating floor, which clicks on top.

Key characteristics:

  • Thickness: 0.3–0.5mm (negligible floor height addition)
  • Installation: laid loose under floating floor — can be removed
  • Compatible with: laminate, LVT vinyl, engineered wood (with UFH rating)
  • Not compatible with: tiles (adhesive covers film and prevents heat emission)
  • Heat-up time: 5–10 minutes (fast response)
  • Typical output: 80–150W/m²
  • Lifespan: 25–30 years
  • Cost: €18–€30/m² for film only; €45–€65/m² fully installed with laminate

Head-to-head comparison

  • Installation speed: Film wins — a room can be done in a day. Mat requires tiling to cure (3+ weeks before use).
  • Heat-up time: Film wins — 5–10 minutes vs 20–40 minutes for mat/tile.
  • Heat retention: Mat wins — tiles store heat and stay warm even after the system switches off. Film/laminate cools more quickly.
  • Suitability for bathrooms: Mat wins — heating film should not be used in wet areas.
  • DIY-friendliness: Film wins — straightforward to lay under floating floors.
  • Running costs: Similar — both systems are 100% efficient. Film's lower output may mean slightly lower bills for the same comfort.
  • Reversibility: Film wins — can be removed if flooring is replaced.

Which rooms suit each system?

  • Bathroom: Always mat (tiles are standard in bathrooms, film not suitable for wet areas)
  • Kitchen: Usually mat (tile floor most common in Tenerife kitchens)
  • Living room: Mat if tiled, film if laminate or vinyl — both are excellent
  • Bedroom: Usually film (most Tenerife bedrooms have laminate or parquet)
  • Hallway: Usually mat (tile is most common and most practical)
  • Office: Usually film (laminate most common)

Can I have both in the same property?

Absolutely — and this is the most common scenario. A Tenerife apartment typically has tile floors in the bathroom, kitchen and hallway (heating mat), and laminate or parquet in the bedroom and living room (heating film). We routinely install both systems in a single property, connecting to separate thermostat circuits so each room is controlled independently.
