COVER STORY DESIGNED WITH Here, ThermoSphere provides a guide to electric underfloor heating opt


The demand for warm floors continues to rise post- pandemic and it isn’t going to slow down any time soon. In fact, the Rated People Home Improvement Trends Report 2021 highlighted that electric underfloor heating ranked fourth in the number of eco jobs posted. There’s good reason for this. Electric heating is increasingly seen as the environmentally-friendly alternative to gas, it is 100% efficient at point of use and affordable to install and run.


ELECTRIC UNDERFLOOR HEATING FOR TILE AND STONE FLOORS


THERMOSPHERE MESH Designed and made in Great Britain and only 3.5mm thick, ThermoSphere Mesh stands alone as the very best electric underfloor heating mat in the market. The fully self-adhesive mesh sticks to the substrate wire side down which protects the fully earthed TwistedTwin heating cable when tiling and speeds up the installation process.

TOP INSTALLATION TIPS Choose the right heat output


ThermoSphere electric underfloor heating comes in a range of outputs and is available pre-spaced on self- adhesive mesh, or in loose cable that you can configure exactly to your floor space.


Modern properties with good insulation are likely to require less heat to keep warm, so you could opt for either a 100W/m2


or a 150W/m2 insulation boards. A 200W/m2


system with underfloor system is ideal in rooms


that you don’t use often and want to heat up quickly, but only for a short amount of time. A good example is a shower room or en-suite. In this type of room ThermoSphere Membrane would be ideal because it has the added benefit of waterproofing the floor.


Some properties have large, glazed elevations that can cause heat loss in the areas next to the glass. In areas like this it is wise to use 200W/m2


electric underfloor heating — 12 —


to provide a warm air curtain that combats the cold. The rest of the floor can be 100W/m2


or 150W/m2 Make sure the electrical circuit is suitable


As part of the installation process, you will need to call in a professional Part P registered electrician. Most average sized heated bathroom or kitchen floors can be powered by a simple 13A fused spur connected to the existing ring main. The electrician will make sure that there is enough load capacity on the existing circuit to support the new heating system and if not, they can install a dedicated circuit with the correct size fuse to power the heated floor. Every electric underfloor heating circuit must be protected by a 30mA RCD for safety.


Don’t sacrifice insulation to save height


Insulation is a key part of any underfloor heating installation and can make the system up to 50% more efficient. Without it, some of the heat generated will get lost through the floor substrate and the system will take
