Radiators vs underfloor heating
Radiators heat a room from a fixed point using convection and radiant heat, and respond relatively quickly to control changes. Underfloor heating spreads warmth evenly across the whole floor area at a lower water temperature, which suits heat pumps particularly well but takes longer to change room temperature.
What is actually going on with radiators and underfloor heating
Underfloor systems free up wall space entirely, remove visible radiators, and distribute heat more evenly, but installation is disruptive unless done during a new build, extension or full renovation when floors are already being lifted. Radiators are far simpler to retrofit into an existing property and reach temperature more quickly, which suits rooms used intermittently. Floor finish also matters, since some coverings conduct underfloor heat better than others.
Practical notes on radiators and underfloor heating
- Underfloor heating runs at a lower flow temperature than radiators
- Radiators respond to control changes noticeably faster
- Underfloor installation is disruptive to retrofit without floor works
- Floor covering type affects underfloor heating performance
- Underfloor heating pairs particularly well with heat pumps
Where we deal with this
Who should undertake the work

Services that cover this
Questions we get asked
- Can I mix radiators and underfloor heating?
- Yes, commonly underfloor downstairs and radiators upstairs, controlled on separate zones.
- Is underfloor heating slower to warm a room?
- Generally yes, because of its lower operating temperature and the thermal mass of the floor itself.
