What is underfloor heating?

Underfloor heating systems utilise the entire floor area within a room as a heat emitter, delivering ultimate comfort effectively and efficiently.

What are the benefits of underfloor heating?

Underfloor heating is an effective and efficient choice of heat emitter. It transforms the entire floor surface into an area where warmth can be emitted into a room, evenly heating the space up and delivering optimal comfort. Visit our Knowledge Hub to read more about the many advantages of installing an underfloor heating system

Can underfloor heating be added to my existing heating system?

Underfloor heating is suitable for gas, oil, and LPG boilers as well as heat pumps and biomass boilers. For more information, speak to our Renewables Team.

Is my home suitable for an underfloor heating system?

Yes. With so many underfloor heating systems available, there is a system that will suit your home whether that be a traditional screeded UFH system, a low profile UFH system, a dry, non-screed UFH system, or installation options (such as heat emission plates) for first and upper floor areas.

Which underfloor heating systems best suit retrofit installations?

Low profile underfloor heating systems lend themselves well to retrofit installations because systems, such as the Grant Uflex MINI UFH, use self-adhesive panels which can be laid on top of an existing floor, providing it is sound and level, and using a self-levelling compound to create the finished floor surface. Furthermore, low profile UFH systems may not affect existing door and skirting board arrangements. Dry, non-screeded UFH systems are also ideally suited for existing properties as there is no need to dig up existing floors.
