Electric Underfloor Heating

An electric heating element is 100% efficient at the point of use meaning every watt of electricity is converted into heat energy. Couple that with a thermal insulation layer and energy saving heating control and you have an extremely efficient heating system.

Every system is different because of the type of flooring used and the level of insulation below the heating system.

You can use our running cost calculator to estimate to get a good idea on how much it will cost to run.

Many of our electric underfloor heating systems can be installed in just one day (depending on the size of the system). After installation you must allow time for any adhesives to fully cure before switching your system on. This is usually around 1-2 weeks.

It is perfectly safe to install a ThermoSphere Mesh or Membrane system in a bathroom. ThermoSphere Mesh is protected to IP68 standards which means it can be placed in zone 1 of a bathroom with no issues. ThermoSphere Membrane can be used a fully waterproof solution and is ideal for wet rooms. However, the thermostat should be installed away from water sources, outside of zone 2.

Yes it can! Electric underfloor heating can also be used as a primary heat source for large spaces but one thing that is holding it back is the current cost per kWh of electricity is much higher than the cost of gas. If you were to install electric underfloor heating in the same sized room as you installed a wet system, the room heated with the electric underfloor heating would cost 3x – 4x as much to run.

It sure can. In fact we've written a comprehensive guide to repairing electric underfloor heating which will help to alleviate any concerns you may have.

There is a simple calculation to work this out.

Floor Area (m2) – Area taken up by fixed units (m2) = Total Underfloor Heating (m2)

What do we mean by fixed units?

As an example, let’s take a typical bathroom. The fixed units will be things like the bath tub, sink and toilet. Also, it is worth considering what furniture you will be having in the room. Any type of flat-bottomed furniture like sofas and bookcases will restrict the airflow to the floor and in turn cause ‘thermal blocking’. This can result in the heating cable overheating causing damage to the floor above. So, if you are planning to have this type of furniture, we would recommend including these as ‘area taken up by fixed units’ within your calculation. TOP TIP - always go slightly smaller in your calculation so you don't have excess matting or cable to try and find a home for, as this usually leads to install mistakes!

Yes, it can be shortened. Minimum length is 1m. NEVER CUT THE HEATING CABLE THOUGH!

Yes, if the country has 230v power supply. It is always a good idea to check local regulations.

We always recommend using insulation board because it helps to improve the efficiency of the electric underfloor heating system by up to 50%! This also means that it will cost you less to run.

No – never. Cutting the heating cable will alter the resistance and cause the element to overheat. If you cut the cable by accident, please contact us.
