Underfloor Tile Heating Ideas from Walls and Floors

If you’re laying some new floor tiles in your home this season, bear in mind those colder winter nights, and consider fitting some underfloor heating. It’s much more energy efficient that you might think, and often it’s a more affordable way of heating a room than to have the radiators on! 

How to install underfloor heating: The basics

For a detailed description of how to arrange the power feed of your underfloor heating, read the instructions that come with your Thermonet matting. It may involve cutting a channel into the floor and running a power cable through it. But, essentially, when looking at the layers involved when fitting underfloor heating, it’s really a very simple job! 

If you’re working onto wooden floorboards, your first layer needs to be Dural Durabase Matting. This yellow matting comes on a roll, and you simply roll it out, covering the space where you wish to have your underfloor heating. If you’re working with a hard concrete floor, you can ignore this step, and continue with the next step… 

Next, it’s time to lay your Thermonet matting. There are two outputs available; a 200W option, and a more eco-friendly 150W option. Lay the matting with the cables face-down, so that they’re protected by the underfloor heating mesh netting. When you reach the end of a stretch and you want to double back on yourself, use a knife to cut a straight line through the netting (being careful not to cut the wire). Once this is done, you can rotate the matting 180 degrees, so that it runs alongside itself. The wire will simply bend, with no damage. Again, check with the instructions to ensure your matting is wired in correctly, and that your thermostat has something to connect with. 

Now it’s time to apply your floor tile adhesive – directly onto the top of the matting. Make sure you use a floor tile adhesive that is suitable for use with underfloor heating, such as our own-brand Kwik Flex Floor Tile Adhesive, which is cement based and rapid setting. 

Take a tile trowel and spread your tile adhesive all over the floor, creating a nice even base. Try to work to an area of one Sqm at a time – or as much area as you can tile onto because the adhesive starts to set. Use the notched edge of the trowel to rake grooves into the adhesive bed, and push your floor tiles into it – giving them a slight twist to ensure good adhesion. Moving from tile to tile, use a spirit level to ensure they remain level. 

Make sure you use a tile that is suitable for use with underfloor heating. At product level, in the tile specs, you’ll see a ‘Suitable for use with Underfloor Heating’ line if this is the case. 

Once your floor has set, and you’ve connected up your thermostat, it’s time to enjoy your underfloor heating. For the full effect, take your shoes and socks off! No more chilly tiled floor.
