Product details

The SmartHeat S-Mat Electric Underfloor Heating Kit combines a 150 W/m² heating mat with a Wi-Fi thermostat for convenient floor temperature control. Its slim 2.5 mm heating cable is designed for thin screed installations where installation depth is an important consideration.

The single-conductor heating cable uses a two-point connection and is attached to an adhesive-backed fibreglass mesh. This roll-out format maintains consistent cable spacing and helps simplify positioning during installation.

Available in heated areas from 1 to 12 m², each kit includes a SmartHeat Wi-Fi room thermostat, floor temperature sensor, Screamer warning device and wall mounting box. The thermostat provides a digital display, 7-day programming and remote control via Wi-Fi.



How to Install an Electric Underfloor Heating Mat (150W/m²)

Please note: This video features the 200W/m² twin-conductor model, which has a different electrical connection setup. However, you can still refer to it for the general mat installation process.
