Electric Underfloor Heating for Timber Floors

Our Harmoni smartmat 100W has been designed to be used on a range of timber based floors such as suspended timber floors, timber joists or floorboards. The mats themselves use an ultra-thin cable which then provide an even heat distribution across your floor surface. For all sub floors constructed of wood, this is the heating mat most suitable for your installation. They can be used with a variety of floor covering such as carpet, vinyl, and tiles which includes ceramic, marble, limestone, and slate.

If you are looking for electric underfloor heating for laminate and solid wood, you will need to use foils which have been created to be used under these types of flooring systems. For any new build projects, heating cable would be the best system to use.

Underfloor heating for timber floors

Our Range Of Products

Our mats are all 0.5 metres wide, and lengths are available starting 1 metre long which covers an area of 0.5m². The lengths of the mats go up in 1 metre increments up to 4m, and then 2m increments up to 30m. If your floor surface is larger than 15m², you can combine different sizes to get the final size you need. Each of our underfloor heating mats features a self-adhesive mesh, an ultra-thin heating cable, and twin conductor heating cables. They are suitable for most wooden sub-floors and have an output of 100w/m². With a 100% aluminium earth sheath for extra safety, there won’t be much height added to your overall floor height as the cable thickness is only 3mm. With an operating voltage of 230/240v it also has a 3m cold tail connection lead.

Electric Underfloor Heating Kits

With our range of products, it’s quite easy for you to create your owns kits. Simply select the size of mat you require, add a thermostat, and then add the optional fixing kit. This makes up a full electric underfloor heating kit and contains everything you need to install your heating mats. All of this can be done on the product page when adding the product to your basket.

Lifetime Warranty

We are proud to offer a premium electric underfloor heating range that offers unbeatable value. All Harmoni mats, foils & cables are guaranteed against manufacturer defects for the lifetime of the initial floor covering. This means that they have a lifetime warranty plus an installation replacement warranty. All underfloor mats, foils and cables are safety approved products and have been verified with independent S Mark & Fimko. We offer a free design service and a fully detailed quotation, along with free next day delivery or local collection.

Installer Warranty

In an ideal world, floor surfaces are laid as soon as the previous step has been completed but delays can happen which means leaving the mats exposed. Accidents can happen and mats can get damaged before the floor covering is added which is why we offer an installer warranty. This guarantees that if you damage your Harmoni mat, foil or cable before the finished floor surface is installed, we will replace it with an equivalent product free of charge.
