Is underfloor heating more expensive to run?

Compared to a traditional radiator system, if designed and installed correctly, a wet underfloor heating system is around 25% more efficient. By evenly distributing the underfloor heating pipes, the system runs at a lower temperature, reducing your energy consumption and carbon footprint.

There are two ‘types’ of underfloor heating; Wet or Electric.

Wet UFH systems can entirely replace your existing central heating system, and electric UFH systems combine with existing heating to improve heating. 

Costs vary depending on the type of system required; the floor build-up determines this. If you aren’t sure which you need, please contact our technical team, who can guide you through the different options and provide a quotation. 

Yes! A wet underfloor heating system designed by our experts would run as a standalone system and wouldn’t need a combination of UFH and radiators. 

Generally, yes. As underfloor heating runs at a much lower temperature than a typical radiator system, this reduces the energy used, lowering both bills and carbon footprints. 

Liquid screeds are faster to install due to their free-flowing nature. Screeds can be poured in larger surface areas and with greater accuracy. Due to its high flexural strength, the screed can be force-dried after seven days. The UFH system can be commissioned early to achieve this. A liquid screed is less likely to crack than a dry screed and requires less movement or control joints. Bay sizes up to 20m in length, maintaining an aspect ratio of 1:6. Can be achieved. Liquid screed has higher thermal conductivity values typically (2.2W/mk). The screed can be placed at thinner depths than a traditional screed, resulting in improved reaction times and reduced flow temperatures. Liquid screeds generally cure quickly, giving sufficient strength to allow foot traffic after 24-48 hours. A liquid screed is more robust and more durable than a semi-dry screed.

A competent DIY’er can install underfloor heating, although it is essential to ensure they have a designed pipework and system layout to work from. Once installed, a suitably qualified person will be required to connect our systems to your boiler (Or another heat source) and undertake any electrical works. 

Underfloor heating works well with various floor finishes, including carpets.

 It is essential that the carpet is low tog carpet where possible; please see our floor finishes guide for further information

Underfloor heating runs at a lower temperature than a typical radiator-designed system, so it doesn’t require as much output. If the current boiler is designed and sized for radiators, usually, it will be more than adequate to serve a correctly designed underfloor heating system.
