The Thin Bed heating set DANFOSS DEVI 1-450W 140F0820 is a complete underfloor heating solution for tiled floors covering approximately 3.0 m². The set contains a 450 W heating cable mat sized to match small to medium bathroom or kitchen areas and the DEVIreg Touch thermostat for precise temperature control. The system is intended for embedding in thin-bed tile adhesive and delivers uniform radiant heat to reduce cold spots and improve floor comfort in both retrofit and new-build projects.

Advantages

The product combines a pre-spaced 450 W heating mat with an intuitive DEVIreg Touch thermostat, enabling accurate temperature regulation and simple operation. Installation in a thin-bed layer allows a low-build solution without raising floor levels significantly. The DEVIreg Touch offers programmable temperature settings and responsive sensor feedback for efficient energy use. The set is suitable for tiled finishes and is designed to provide even surface warmth and reduce the need for supplemental heating.

How to use

Prepare the subfloor according to manufacturer's installation guidelines: ensure it is clean, level and suitable for thin-bed tile adhesive. Lay the heating mat in the planned layout and secure it to the subfloor, avoiding overlaps. Connect the heating mat to the DEVIreg Touch thermostat and fit the temperature sensor in the recommended position within the tile adhesive. After electrical connections are completed by a qualified electrician and the system is tested, cover the mat with tile adhesive and finish with chosen tiles. Program the DEVIreg Touch for desired temperature schedules and calibrate the floor sensor if required.

Usage recommendations

For reliable performance and safety, have all electrical connections and commissioning performed by a licensed electrician. Use tile adhesives and floor coverings compatible with electric underfloor heating and follow curing times before switching the system on. Regularly check thermostat settings to optimize comfort and energy consumption.
