Underfloor Heating Cable 100w

Underfloor Heating Cable 100w per square meter. The 100w/m2 heating cable can achieve a gentle warmth on the floor simply taking the chill off of the tiles. Loose wire heating cable is laid free hand, therefore, making it ideal for any awkwardly shaped areas for example in bathrooms. Living Heat heating cable can also be manipulated around curved objects, corners or even tight spaces. The spacing’s between cables can be decreased which as a result will increase the wattage of the system. Also recommended is that an insulation layer is installed under the heating system.

Especially relevant on a concrete sub floor because as a result, the concrete floor will absorb the heat. As a rule of thumb, we would recommend heating between 70 and 90% of your total floor area. Most of all If you have any questions or would just like a little advice take a look at our installation guides. Finally, give us a call for a personal and also free design service on 01803 316060.

If you are looking for a primary heat source our 150w/m2 or 200w/m2 heating cable could be more suitable for your needs.

Underfloor Heating Cable Floor Build Up

Starting at the sub floor which can be either wood or concrete. The following layer will be a thin bed of flexible adhesive about 4mm thick to stick down your insulation boards. Next, you will have your insulation board itself. Creating a base to lay your underfloor heating cable. Once the cable is laid you have two options. In this example we have shown the tiles being laid directly onto the heating cable, however, a self-levelling compound can also be poured over the cables prior to tiling. Providing an even conduction of heat and a protective layer whilst tilling. And finally, the tiles can be stuck down with a standard 6mm bed of flexible adhesive. Please also ensure that the tiles are laid with an even bed of adhesive for equal heat distribution and cable coverage.

So, in conclusion, the floor will be raised dependent on a few variables by:

  • 4mm bed of flexible adhesive.
  • 6mm insulation board. (10mm & 20mm insulation also available).
  • 2.5mm Underfloor Heating Cable 100w. Enveloped into levelling or tile adhesive.
  • 6mm bed of tile adhesive.
  • Tiles in this example 10mm tiles

Making a total additional floor height of 26mm dependent on chosen variables of insulation and tile heights.
