Overview

Description

From the makers of the popular Warmup heating devices comes the SunStone 150W Electric Mat for stone and ceramic tiles. Ideal for regular-shaped rooms, this electric underfloor mat evenly spreads heat around the surface to keep your family cosy and warm during cold days.

This pack covers an area of 12m2. The wire is attached to a glassfibre mesh, making it easier for you to lay it down. If the underfloor heating mat does not fit the shape your room, you can cut the mesh (but not the wire).

The 150w features a blue wire while the 200w uses a red wire to help you tell the difference.

SunStone follows the footsteps of industry-leader Warmup in providing high-quality and energy-efficient underfloor heating technology. SunStone by Warmup is an economical alternative to your heating system because 100% of electric energy is converted directly to heat, compared to boiler-based heating systems.

Really good customer care. We only wanted a small amount of tiles for a downstairs cloakroom. They happily split a larger lot for us. No problem. Great price, and we know they have more if needed. Thank you
