Underfloor heating provides high levels of comfort and efficiency in the home and is the choice of 90% of self-builders.   It’s also used in a large number of commercial buildings where performance of HVAC systems are more frequently considered holistically.  UFH is readily installed during construction and there are many modern systems developed specifically for retrofit, whatever the floor covering.  The same installed equipment can also be used as part of a system to mitigate the effects of overheating in summer.

Because wall space does not have to be given over to radiators, UFH affords designers greater flexibility on layout and window dimensions/placement.  There are however common misconceptions perpetuated from out-of-date information on cost and operation that sometimes lead to a missed opportunities for superior client satisfaction and sales differentiation.

These pages provide information for professionals looking to understand the options available, the benefits and considerations when specifying and underfloor heating system.


Architect FAQs

What are the benefits of warm water UFH?

Warm water UFH offers a host of benefits, creating a luxury, even warmth that is free from draughts and dust movements.

  • UFH is efficient – around 25% more efficient than radiators, helping to keep heating bills low
  • It is an ‘invisible’ heating system that frees up wall space – perfect for open plan living
  • It creates a comfortable living environment – warmth rises gently from the entire floor surface to create the perfect heating profile

Where can UFH be installed?

Warm water UFH can be installed in a wide range of projects including new builds, renovations, extensions and conversion projects. There are many different systems on the market to suit – some of which also offer acoustic properties.

What is acoustic UFH?

Some suppliers offer acoustic UFH floor constructions that are Part E compliant. These combine an efficient heating solution with an acoustic floor deck, reducing airborne and impact sound levels. Depending on the solution, the system can be fitted at first or second-fix stage.

What floor coverings can be used with UFH?

UFH is compatible with most floor coverings, even carpet! Certain floor coverings offer a better heat transfer than others, such as tiles, but providing the UFH system has been designed correctly the room/s will always meet the desired temperature.

How is warm water UFH controlled?

UFH can be controlled by a standard dial-type thermostat, or remotely via a smartphone, tablet or even home automated system.

Retrofit and floating floor UFH systems heat up quickly and are more responsive than a traditional screed system, so can be controlled in a similar way to a radiator system. A screed UFH system takes time to heat up from cold, so is best used with a ‘setback’ temperature – this achieves an extremely high level of efficiency.
