Under Tile Heating

Electric under floor heating is fast becoming a popular form of heating, especially where cold surfaces such as tiles, stone and marble are used. Under tile heating was invented by the Romans some 2000 years ago, but today it is used in many countries around the globe.

It is currently used extensively in bathrooms, kitchens, conservatories and sun rooms – in fact it can be used in any room where a tile, stone or marble floor is being fitted.

Suitable sub-floors

Any sub-floor suitable for tiling over should be suitable for the under tile heating system. In general these will be concrete or plywood, however some water-resistant chipboards may also be OK if adequately fixed down (please check with your tiler).

Standard chipboard and MDF are not considered suitable surfaces on which to tile.
The heating capabilities and warm-up times will vary depending on the subfloor; timber sub-floors and insulated concrete will perform better than uninsulated floors. In all cases the use of an insulated tile-backer board will greatly reduce warm-up times and subsequent running costs.

How does under tile heating work?

The heating cable is simply installed within the flexible tile adhesive layer or thin latex levelling screed.
It is then connected to an electrical supply via the digital thermostat, which regulates the floor temperature. The thermostat has its own built-in 7 day timer so the system can be programmed to suit your own individual requirements and lifestyle.

The installation itself is a straightforward DIY job, but we always recommend that the electrical connections are carried out by a qualified electrician in accordance with current wiring regulations.

Heating Cable

All our systems use the latest design heating cable with an earth screen and a double insulation layer.
The cable also contains a built-in return, meaning that you only have to connect it to the mains from one end.
With these design features we are able to offer a Lifetime Guarantee.

The main advantages of our under tile heating systems are:

  • Invisible – no unsightly radiators or wall-mounted heaters
  • Maintenance free – no servicing or maintenance needed
  • Economical – low running costs
  • Controllable – by means of the digital thermostat
  • 3 mm heating cable – having little effect on the floor height
  • Twin-core heating cable – just one ‘cold’ end to connect
  • Suitable for timber or concrete sub-floors

How to select the correct system

In order to cater for all requirements and room sizes, we supply a wide range of kit sizes. Selecting the system is in may cases a matter of personal choice, but in general where the system is being installed in a bathroom or small kitchen with fixed objects to work around (such as showers, WC’s or kitchen units), most people find the cable kit an advantage.

The cable kit offers the installer complete freedom to space the heating cable evenly over the open floor – no matter how awkward the room shape – and thus avoid the problem of any cold spots.
