Electric Underfloor Heating

Curious about electric underfloor heating? Find how it operates, whether it's costlier to run than traditional heating systems and whether it's a DIY-friendly installation process with these frequently asked questions.

 

How does electric underfloor heating work?

Electric underfloor heating operates through a system of electric cables or mats, drawing power from your electrical supply and regulated by a thermostat. Various types of electric underfloor heating systems cater to different floor types.

This system involves the installation of fine heating wires beneath the floor's surface. Positioned above a screed layer for flatness and floor insulation to prevent downward heat dispersion, these wires generate warmth when the system is activated. The heated wires raise the floor's temperature.

 

Is electric underfloor heating expensive to run?

Electric underfloor heating systems are typically more expensive to run when compared to water-based systems. However, the actual expense varies based on factors such as the cost of electricity, system size and the level of flooring insulation.

Installation and maintenance costs for electric systems are generally cheaper because the installation process is simpler.Using prefabricated mats simplifies the installation process, although wiring might be necessary for smaller rooms.

In comparison to traditional radiators, underfloor heating systems might be more costly to run but they are also more efficient. If your property is well insulated, this enables your rooms to retain heat for longer. Therefore, although the initial investment for the system might be higher, the overall energy bills tend to be lower due to enhanced efficiency and heat retention.

 

Can you fit electric underfloor heating yourself?

When it comes to fitting electric underfloor heating, much of the initial work can be handled independently, although for the mains connection, you might need to hire an electrician. DIY installation for electric underfloor heating tends to be easier than setting up a water-based system.

Underfloor heating cables can be affixed to a mat or laid out freely across the room. You can opt for wiring available in matting rolls, which simply need to be unrolled without the need to position individual wires. When laid loosely, these cables usually rest under a floor screed, and the cables themselves are more substantial.

It will be necessary to hire an electrician for the final mains connection. Especially in the case of larger floor areas, careful planning is necessary for the cables and mats due to essential load calculations ensuring safety.
