Underfloor Heating FAQs
The questions we get asked most — answered plainly. Can't find yours? Just call.
Can underfloor heating be retrofitted into an existing floor?
Yes, in most cases. Low-profile wet systems and electric mats can both be retrofitted, depending on the existing floor build-up and how much height can be given up. A site visit is the best way to confirm what's possible.
What's the difference between wet and electric underfloor heating?
Wet systems circulate warm water through pipework from a boiler or heat pump, and suit larger areas and whole-house installs. Electric systems use heating cables or mats and are usually better suited to single rooms or smaller retrofits.
Does underfloor heating work under any flooring?
Tile and stone conduct heat best. Engineered wood, laminate and vinyl also work well provided the product is rated for underfloor heating and the system is set up and controlled correctly.
Is underfloor heating expensive to run?
Wet underfloor heating runs at lower water temperatures than radiators, which can make it efficient — especially with a heat pump or modern condensing boiler and good insulation. Actual running cost depends on the system type, insulation, controls and your energy tariff.
Why does my underfloor heating have cold spots?
Cold spots are most often caused by an unbalanced manifold, air trapped in the pipe loops, or a partially blocked loop. These can usually be diagnosed and fixed without lifting the floor. See our repair & servicing page.
Do you repair systems you didn't install?
Yes. We regularly diagnose and repair underfloor heating systems installed by other companies across Sheffield and South Yorkshire.
How long does an installation take?
It depends on the size and number of rooms and whether it's a new build, extension, or retrofit. A single-room retrofit is typically much quicker than a whole-house system. A time estimate comes with every quote.
Are you Gas Safe registered?
