Danfoss Devi Thin-Bed Heating Mat 150 W/m² 6 m² 0.5 x 12 m (140F0474)

Electric underfloor heating mat for thin-bed installation beneath tile or natural stone, delivering a consistent 150 W/m² across 6 m² to warm floors efficiently without significantly raising room air temperature.

Advantages

The mat provides even radiant heat with a compact profile, minimising additional floor build-up. Installation is straightforward when embedded in tile adhesive, and the system is compatible with tiled and stone floor finishes. The fixed power density ensures predictable heat output and facilitates accurate load planning for thermostats and electrical circuits. Designed for under-tile use, the mat helps reduce cold spots and contributes to better comfort on tiled surfaces.
