Underfloor heating mat DANFOSS DTIF-150 150 W/m², 1.5 m²

DANFOSS DTIF-150 is a 1.5 m² electric underfloor heating mat with a fixed output of 150 W/m². Designed for tiled and similar floor finishes, the mat delivers even, localized heat across small to medium floor areas. Its factory-terminated heating cable is embedded in a flexible mesh that can be cut to shape (not to the cable) for retrofit or new-build installations. The product is intended for use where quick, efficient underfloor warmth is required, such as bathrooms, kitchens or targeted zones within living spaces.

Advantages

The heating mat ensures uniform heat distribution and stable surface temperatures suitable for tile and stone coverings. Its flexible mesh simplifies layout and positioning on subfloors, while the fixed power density removes the need for on-site cable spacing calculations. Factory-terminated cable reduces installation time and the risk of incorrect field terminations. The system supports efficient, localized heating that can reduce reliance on central heating for small zones.

Suitable for

• Bathroom floors with tile or stone finishes
• Kitchen areas requiring underfloor warmth
• Retrofit installations over existing subfloors
• New-build projects for room-by-room floor heating
• Supplemental heating in specific zones such as entryways or utility rooms

Key specifications

• Mat area: 1.5 m²
• Nominal heat output: 150 W/m²
• Total power: 225 W
• Heating cable embedded in flexible mesh for easy laying
• Factory-terminated cable for safer and faster installation
• Suitable for tile, stone and similar floor finishes
• Intended for installation under floor coverings with appropriate insulation and thermostat control

How to use

Prepare the subfloor by ensuring it is clean, dry and level, and install suitable thermal insulation according to local regulations. Lay the DANFOSS DTIF-150 mat with the heating cable embedded in the mesh facing up, cutting and turning the mesh itself to fit the room shape while avoiding cutting the cable. Fix the mesh to the subfloor using recommended adhesive or tape, maintain required clearances from walls and fixed fixtures, and connect the factory-terminated cable to a compatible thermostat and residual-current device by a qualified electrician. Cover the mat with a thin layer of levelling compound or tile adhesive and finish with the chosen floor covering.

Usage recommendations

Use a programmable thermostat with floor sensor for accurate temperature control and to protect the floor covering. Verify compatibility of floor finishes with electric underfloor heating and follow local electrical and building codes. For safe and compliant installation, have electrical connections performed by a licensed electrician and consult the manufacturer’s installation manual for detailed instructions and required installation distances.
