200w/m2 Loose Wire Underfloor Heating Cable Kits

The 200w/m2 loose wire underfloor heating cable option, is the perfect solution when looking to use the electric heating as a primary/sole source of heating. The choice of the professional under Tiles or Natural Stone, it can also be installed under any floor, when embedded in a latex/self levelling compound.

At only 2mm thickness, it is the lowest profile heating element on the market. The perfect option, when looking to achieve wall to wall heat coverage, especially suitable for small WCs, Bathrooms or Wet Rooms.

The wire is rated at 12w per linear metre and will provide 200w per sqm when spaced 60mm apart. As an example our wire is 200m long (the largest loose cable in the UK). This wire would cover 12sqm(at 60mm spacings/200w per sqm). On larger rooms/zones, multiple thermostats or a 25amp or 40amp relay may be required (dependent on electrical load/heated area).


The loose wires can be laid directly on to a stable wood, concrete or screed sub-floor. To drastically increase the efficiency and the response of your heating, we recommend either a cement coated tile backer board, or an XPS board to be installed under the heating.

The use of insulation is especially important over sub floors without inbuilt insulation / older properties as they will minimise any heat loss downwards. The heating should then be be embedded with either a self levelling compound or flexible tile adhesive, before your final floor covering is laid.

Electric Vs Water - What is the difference?

The common misconception is that electric underfloor heating is far more expensive to buy and run than it's water/gas counterparts. In truth, electric heating can be very efficient, when controlled correctly from the thermostat controller.

Unlike water based heating which is predominantly regulated off an air sensor, electric heating should always be controlled off a floor sensor. This enables the heating to be far more efficient and responsive as a heat system and far quicker at heating the room or floor, as opposed to the underfloor water pipes or radiators.

Because electric underfloor heating heats from the floor to 6 feet up, there is no wasted energy costs in heating the ceiling, which is always the case in regards to heat being supplied from radiators.

Of course, the main benefit of underfloor heating is that there are no unsightly radiators required in most instances. When covering over 80% of the floor with electric heating, the heating can be used as a sole source of heating. As a sole source of heating, it is our recommendation that a 200w system with insulation be installed.

Electric heating can be also used as a comfort heat source or to take the cold chill off the floor, when installed in certain areas where you would like a warm floor, however would work alongside other forms of heating in this instance.
