Frequently Asked

  • Can underfloor heating be used in any house?
    Circoflo provides a range of systems which are suitable for most houses and floor constructions. Underfloor heating can also be retrofitted into your home too with only a very minimal or no build up. Click here to specify your project and see if your underfloor heating will work in your home.


  • How much does underfloor heating cost to run?
    The running costs of underfloor will vary, however, a water underfloor heating system is one of the most efficient means of heating your home. This is because, unlike radiators which can be as hot at 75°C, underfloor heating runs at much lower temperatures of between 35°C and 55°C.


  • Which underfloor heating system do I need?
    The type of underfloor system you will require will depend on what floor construction you are installing the system into. Circoflo supplies systems for screeded, solid and joisted and battened floors.

Screeded Floors:
Although it takes slightly longer for this floor construction to warm up, screed is a good thermal conductor meaning it has the best heat output and will retain the heat for longer. Find out more about ClipRail – Circoflo’s high performance screeded system.

Solid Floors:
Underfloor heating can be laid over a solid floor using floating systems. The panels are laid directly onto the floor before the covering layer and floor finish are installed on top. As this construction is completely ‘dry’, it is perfect for easily retrofitting within renovation projects. Circoflo floating systems are designed so that there is a minimal height build up on the existing floor. The panels are also strong enough to provide sufficient support for the floor loads and to stop sagging over time. Find out more about FloFloor and LowDeck – The two Circoflo floating systems.

Joisted & Battened Floors
Underfloor heating can be installed between joists or battens using brackets which support the ‘suspended’ panels. The benefits of this construction in a joisted situation are that there is absolutely no height build up and it easily allows the installation of underfloor heating on upper floors.

  • What heat sources can I use with underfloor heating?
    Any heat source can be used with underfloor heating from boilers to renewables (such as heat pumps).


  • What floor finishes can I use?
    Most floor finishes are suitable for use with underfloor heating however the resistance of the floor finish (how much it insulates) will affect the heat output. Tiles, stone, wood and even carpet (up to 2.5 TOG) can all be used with underfloor heating. However, make sure that you always read and follow the manufacturer’s guidelines before choosing your floor finish.


  • Can I use underfloor heating throughout the whole house?
    Yes, underfloor heating can be installed throughout the whole house and multiple zones.


  • Can underfloor heating be used in renovations?
    Underfloor heating is ideal for renovations and all Circoflo systems can easily be retrofitted into your home. Underfloor heating can also be connected to new or existing boilers and even run in conjunction with radiators. When retrofitting underfloor heating, it’s important take your home’s heat losses into consideration as houses with poor insulation may not benefit from underfloor heating.
