Description
Amber 150W/m² Electric Underfloor Heating Mat — Concrete Floors — 0.5m² to 12m²
The Amber 150W/m² Electric Underfloor Heating Mat is engineered specifically for concrete and solid subfloor constructions, delivering powerful, even radiant warmth underfoot. At 150W per square metre, it provides a higher heat output than standard 100W mats — making it the correct choice for concrete floors, which require more energy to reach a comfortable temperature than timber subfloors. EU-certified manufacturing and a market-leading warranty give complete confidence from installation through to daily use. Available in 15 sizes from 0.5m² to 12.0m², all 500mm wide.
⚠️ Electrical connections must be made by a qualified electrician. All wiring to the mains supply must be carried out by a Part P registered electrician in accordance with BS 7671. Not sure which size you need? Email your room dimensions to

Frequently Asked Questions
Why 150W/m² for concrete floors?
Concrete has a high thermal mass — it absorbs and stores heat, requiring more energy to reach a comfortable temperature than a timber subfloor. A 150W/m² output compensates for this. For timber subfloors, the Amber 100W Heat Mat is the correct choice.
Can the mat be cut to fit?
The mesh can be cut to allow the mat to turn corners or navigate around obstacles. The cable must never be cut — cutting the cable will damage the heating element and void the warranty.
Do I need a thermostat?
Yes — a thermostat is required to control the heating mat and prevent overheating. See the Amber DT1 or DT-two+ Smart Thermostat.
Can I order if the item shows as out of stock?
Yes — available to order even when stock shows as zero. Call us on 01603 381095 or email customerservice@bubblegumbathrooms.co.uk to confirm availability.
