There are two types of underfloor electric heating systems available in the UK.  Heating cables and mats are generally used for under tile heating, whilst carbon film heating elements are used under wood or laminate floors.  This type of floor heating system is ideal for areas where an increase in the finished floor height is undesirable.

The heating cables and mats used for under tile heating have a thickness of just 3mm.  The cables have twin core resistance wire conductors, covered by a sheath of PTFE, a screening foil, an earth braid and lastly, an outer jacket of PVC, which makes the cables waterproof.  When an electric current is passed through them the cable heats up; the maximum temperature achieved will depend on the design of the conductor wires.

Electric Cables

Loose cables can be used for floor heating, but the installer must tape the cables in place, which can be time consuming.  Generally, cables are only recommended for small areas, such as bathrooms.  Some experience in their fitting is required to achieve optimal results.

Heating Mats

Underfloor heating cables can also be supplied on a mesh backing, to produce heating mats.  The output of these mats varies, allowing them to be used in different areas.  Conservatories lose more heat than other areas of the home and so require a higher output. 

Heating mats are a better option for anyone carrying out a DIY underfloor heating project.  The mat backing can be cut easily, so the mats can be fitted around obstacles, such as fitted units or kitchen islands.  In addition, it is possible to remove the heating cables from the mat and use the loose cable for any areas that are hard to access; for example, door recesses.
