Why choose underfloor heating under tiles in Tenerife?

Tiles are the most common flooring in Tenerife homes — practical, easy to clean, and suited to the climate. But in winter, tile floors become one of the biggest sources of cold discomfort. Tile has very high thermal mass: it absorbs cold and radiates it upward, making rooms feel 3–5°C colder than the actual air temperature.

Installing an electric heating mat under your tiles solves this completely. The mat heats the tile from below, turning it from a cold radiator into a warm one. The floor surface reaches a comfortable 22–28°C — warm enough to walk on barefoot, and warm enough to gently heat the room.

Best rooms for heated tiles in Tenerife: Bathrooms, kitchens, hallways and ground floor living rooms — any room where tile floors make evenings feel cold.

What's included in a full tile installation?

Our full installation service covers the complete project from demolition to finished floor:

  • Tile removal: We carefully remove existing tiles and dispose of the waste
  • Surface preparation: Substrate levelled and prepared for the heating mat
  • Heating mat installation: Professional electric heating mat laid to the floor plan
  • Sensor installation: Floor temperature sensor installed between cables
  • Tiling: New tiles laid over the mat using flexible tile adhesive (essential — standard adhesive cracks with thermal expansion)
  • Grouting: Professional grouting with flexible grout
  • Thermostat wiring: Thermostat sensor cable connected, wall thermostat fitted
  • Electrical connection: System connected to your electrical panel by our certified electrician
  • Testing & handover: System tested, thermostat programmed, instructions provided

Which heating mat do we use?

We use professional-grade double-insulated heating mats from leading European manufacturers including Fenix, Devi and Warmup. These are specifically designed for installation under tiles and ceramics, with self-adhesive mesh backing for easy positioning. Standard outputs are 150W/m² for most rooms and 200W/m² for bathrooms.

All mats carry CE certification and comply with Spanish electrical regulations (REBT). Each installation is documented and you receive a full warranty certificate.

What tiles can go over the heating mat?

Almost any ceramic or porcelain tile can be used over an electric heating mat, with one important condition: the adhesive and grout must be flexible (deformable class S1 or S2). Standard rigid adhesive will crack as the tile expands and contracts with temperature cycles. We always use the correct flexible adhesive and grout — this is included in our installation price.

Natural stone tiles (marble, granite, travertine) can also be used, but require extra care due to their lower thermal conductivity. We advise on the right system for your chosen material.

Running costs — what should you expect?

One of the most common concerns is whether underfloor heating is expensive to run. The answer depends on how you use it, but the numbers are reassuring:

  • A 10m² bathroom with a 150W/m² mat = 1500W total
  • At Tenerife's average electricity rate (~€0.22/kWh), running for 4 hours/day costs approximately €0.33/day
  • The thermostat cycles on and off to maintain temperature — actual "on" time is typically 40–60% of set time
  • A 25m² living room at 150W/m² for 6 hours/day ≈ €0.50–€1.00/day

These costs are comparable to running a single oil-filled electric radiator — but the comfort level is far superior and the heat is distributed evenly across the entire floor.

How long does the installation take?

A typical bathroom (5–8m²) takes 2–3 working days including tile removal, mat installation, retiling and grouting. A larger living room (20–30m²) takes 3–5 working days. The main time variable is tile drying and adhesive curing — the heating system should not be activated for at least 21–28 days after installation to allow proper curing.
