Heating mat DEVI 150T 900W for electric underfloor heating, 230V, 0.5x12m

DEVI 150T 900W heating mat is an electric underfloor heating solution designed for tiled or stone floors. The mat delivers 150 W/m² heat output and operates from a 230 V supply. A pre-spaced heating cable is fixed to a mesh backing for direct installation into tile adhesive, making it suitable for full-room installations, renovation projects or targeted heating in bathrooms, kitchens and living areas.

Advantages

The heating mat provides even surface warmth with a consistent output of 150 W/m², suitable for rapid heat-up under tile or stone. The mesh-backed, pre-spaced cable reduces installation time and helps ensure correct cable spacing without measuring. Compatibility with 230 V electrical supply makes the product suitable for standard household circuits, and the 900 W total power supports full-room heating in medium-sized areas or combined spot heating and edge warming in smaller rooms.

Suitable for

• Under-tile or under-stone installations in bathrooms and kitchens
• Full-room electric underfloor heating in medium-sized rooms
• Renovation projects where existing floor height allows embedding in tile adhesive
• Spot heating in areas such as near sinks, shower trays, or around fixtures

When it may not be suitable

This heating mat is designed specifically for tiled or stone floor coverings and may not be appropriate for use under floating wood, laminate, or some resilient floor coverings that require lower surface temperatures. For very large open-plan areas or where the available circuit power is limited, multiple mats or a different power rating may be required to achieve uniform heating.

Key specifications

• Rated power output: 150 W/m²
• Total power: 900 W
• Operating voltage: 230 V
• Mat dimensions: 0.5 m × 12 m
• Heating cable fixed to mesh backing for adhesive embedding

How to use

Install the mesh-backed mat directly into a layer of tile adhesive over a suitable subfloor according to local electrical and building regulations. Ensure the mat is laid with the heating cable side embedded in adhesive and that the cold lead and thermostat connections are positioned for access. After embedding and tile installation, connect the system to a compatible thermostat and 230 V supply by a qualified electrician, and test the circuit before final commissioning.

What to consider before purchase

• Floor covering type — intended for tile or natural stone only
• Available floor build-up depth to accommodate embedding in tile adhesive
• Electrical supply capacity and need for a dedicated circuit and thermostat
• Required heated area — verify 900 W and mat dimensions match the target floor area

Usage recommendations

For reliable performance, install with a compatible floor thermostat and allow a qualified electrician to perform final electrical connections and testing. Use the mat only with floor finishes recommended for electric underfloor heating and follow tile adhesive manufacturer instructions for embedding.
