Underfloor heating mat DEVI 150T 1500W 0.5x20m – electric heating mat 1500 W, 0.5 m width, 20 m length

The DEVI 150T underfloor heating mat delivers 1500 W of electric heating power in a 0.5 m by 20 m mat designed for installation beneath tile, stone or similar floor finishes. The product consists of a pre-spaced heating cable fixed to a flexible mesh that allows straightforward placement and cutting to fit room shapes. Intended for surface heating and frost protection, the mat offers even heat distribution across small to medium floor areas and is compatible with standard tile adhesive and levelling compounds when installed according to local electrical regulations.

Advantages

The DEVI 150T mat provides uniform surface warmth with a high output density suitable for faster floor warm-up compared with low-power mats. Its 0.5 m width makes it easy to unroll and position in narrow rooms such as bathrooms and kitchens. The pre-spaced cable on a flexible mesh reduces installation time and the need for manual cable fixing. The mat is suitable for embedding under tile and stone coverings and supports frost protection for areas susceptible to cold. Designed for professional or DIY fitting when combined with correct floor preparation and an appropriate thermostat, the system offers reliable, maintenance-free operation once installed.

Suitable for

• Bathrooms and shower rooms under tile or stone flooring
• Kitchens and utility rooms with hard floor finishes
• Renovation projects where a slim, surface-mounted heating solution is required
• Areas requiring frost protection on floors or to prevent cold spots

How to use

Prepare the subfloor to be clean, level and properly primed according to the chosen adhesive or levelling product. Unroll the DEVI 150T mat and cut the mesh (not the cable) to shape it around room features and to fit the intended layout. Fix the mat to the substrate using recommended adhesive or fixing materials and cover with tile adhesive or levelling compound before laying tiles or stone. Connect the heating cable to the supply and a compatible floor thermostat or controller following local electrical codes; final electrical connections should be completed by a qualified electrician.

Usage recommendations

For optimal performance, use a programmable floor thermostat with floor temperature sensor and set appropriate maximum floor temperature for the installed floor finish. Avoid placing large insulating objects directly over heated areas. Follow local installation rules and the manufacturer’s installation guide for spacing, junction box location and electrical connection procedures.
