DANFOSS Heating Mat DTIF-150 150 W 1.0 m² – underfloor electric heating mat

DANFOSS DTIF-150 heating mat is a 150 W electric underfloor heating mat designed to cover approximately 1.0 m². The self-adhesive structure integrates a heating cable within a mesh backing to enable straightforward placement beneath tile or stone floor finishes. The product is intended to deliver uniform radiant heat for small areas such as bathroom zones, kitchen sections or local renovation spots when connected to an appropriate thermostat and installed with recommended floor insulation.

Advantages

The self-adhesive mesh allows quick alignment and secure fixing to the subfloor, reducing installation time compared with loose cable systems. With a rated output of 150 W for 1.0 m², the mat provides consistent surface temperatures and even heat distribution under ceramic or natural stone coverings. The low-profile construction is suitable for retrofit installations where floor buildup must be minimised. When combined with a suitable thermostat and correct insulation, the system supports responsive temperature control and improved energy use.

Suitable for

• Under-tile heating in bathrooms and showers (subject to local regulations and waterproofing)
• Kitchen work areas and small floor zones
• Bathroom renovations and targeted local heating upgrades
• Over existing screed or new screed installations with compatible floor coverings

Key specifications

• Heating power: 150 W total output designed for 1.0 m² coverage
• Coverage area: approximately 1.0 square metre
• Construction: heating cable fixed into a mesh backing with self-adhesive layer for mounting
• Suitable floor coverings: ceramic tiles, natural stone, and similar hard finishes
• Installation type: electric underfloor heating mat for embedding in thinset or tile adhesive

How to use

Prepare a clean, dry and level subfloor and fit the recommended insulation where required to reduce heat loss. Roll out the self-adhesive heating mat and trim the mesh (not the heating cable) to achieve the desired layout, following the manufacturer’s spacing guidelines. Fix the mat to the subfloor using its adhesive backing, then secure the heating cable and cover with tile adhesive or thinset before laying the floor finish. Connect the cold lead to a compatible thermostat and have electrical connections performed by a qualified electrician in accordance with local regulations.

Usage recommendations

Use with a floor sensor and a suitable programmable thermostat to maintain efficient temperature control. Do not cut or overlap the heating cable. Ensure full compatibility with the chosen tile adhesive and verify required waterproofing in wet zones. Follow local electrical codes and use a professional for final electrical connection and commissioning.
