Underfloor heating systems can offer a streamlined alternative to radiators

Electric Underfloor heating systems - which can sit beneath stone, tile, wooden or even carpeted surfaces - will help to keep cold floors and rooms toasty, and can offer an alternative to using radiators to deliver central heating.

Here, we look at how an electric system works.

Electric underfloor heating explained

A series of electric wires are installed beneath or within your flooring as a means of heating an area or room - a cold, tiled bathroom floor, for example.

The electric system you install will depend on the size of the room and the type of flooring it has - options include loose-fit wiring flexible enough to fit into small or awkward spaces, electric cable systems, or heating mats you roll out to cover larger areas.

Underfloor heating is generally associated with stone or tiled floors, but you can even fit it in a carpeted room - you'll just need to ensure that the carpet and underlay isn't so dense that it stops the heat moving upwards (a tog of no more than 1.5 is a general rule of thumb). And if you use a under tile system for a carpet area then you will need to lay a minimum 7mm Latex screed over the heating before the carpet goes down.

How electric underfloor heating works

The electric heating sheets or cables are fitted beneath the flooring, and usually on top of a layer of screed (to ensure the surface is completely flat) and a layer of floor insulation (to keep the heating source travelling upwards rather than down). 

A qualified electrician will need to connect your system up to your electric mains supply, or ring mains via a fused spur switch depending on the size of area you are covering, and fit a sensor that connects to the thermostat. This allows you to control the temperature and pre-set the system to turn on or off.

Different electric underfloor heating systems are compatible with nearly all flooring types - if you're unsure, please give us a ring on 01354 669201 so we can advise you on the best product for your room and flooring. 

Because electric systems are generally quite thin, they're easier and less hassle to install in an existing room than a wet heating system, which requires space for pipework and could involve the floor being raised.
