Electric underfloor heating

Three ways to get electricity into the floor

• Heating mats for under tiles. Thin cable on a mesh mat, laid directly into the adhesive beneath the tiles. The build-up increases by only a few millimetres. The most common choice for bathrooms and kitchens.
• Heating cables for screed. Loose cable with adjustable spacing, embedded in a screed layer. Suitable when you require thermal mass and primary room heating.
• Heating foils for floating floors. Thin heating films under laminate or vinyl, no adhesive required. Fast response, ideal for rooms where demolition is not desired.

When electric heating makes sense

When you do not heat the entire house but want a warm tiled floor in the bathroom. When renovating an apartment and you cannot access the heating distribution system. When building a passive house with low heat loss, where a hydronic system is unnecessarily complex. And everywhere where photovoltaic systems are planned, as the floor can store daytime heat from self-generation.

Bathroom: most common job

The mat is laid under the tiles around the bath and shower; the thermostat with floor sensor maintains the set temperature, and the time programme heats the floor before your morning shower. In the bathroom, the floor can reach up to 35 °C, while in living areas it stays at or below 29 °C. Installation including electrical wiring and inspection is completed within a day; tiling follows immediately afterwards.

What is included in the supply

• Power design per m² by room, insulation and floor covering.
• Mat, cable or foil from a manufacturer with warranty, floor sensor in a protective sleeve, thermostat.
• Resistance and insulation status measurement before laying and after screeding, with protocol.
• Electrical wiring, fuse protection, residual current device and inspection report.
• Setting of the thermostat and time programme, handover with documentation for the installer.

Operating costs without embellishment

Electricity is more expensive per kWh than heat from a heat pump, so we recommend electric heating as the main source only for well-insulated buildings or small areas. As supplementary heating for a bathroom or a room where you want comfort, it is the cheapest and fastest solution.
