Underfloor Heating

How does underfloor heating work?

Underfloor heating (UFH) works by circulating warm water through pipes embedded in the floor, radiating gentle heat upward — more efficient and comfortable than radiators.

How Does Underfloor Heating Work?

Underfloor heating (UFH) operates on a simple principle: warm water circulates through a network of pipes laid beneath your floor. Heat radiates upward from the floor surface, warming the room from the ground up.

Wet vs Electric UFH

Wet (hydronic) UFH — water heated by your boiler or heat pump circulates through pipes. This is the most efficient system for whole-house installation and the type RARE specialises in.

Electric UFH — electric heating cables or mats under the floor. Better for small areas (bathrooms, kitchen) as a secondary system.

Why UFH is More Efficient Than Radiators

  • UFH operates at lower flow temperatures (35–55°C vs 70–80°C for radiators)
  • This makes it exceptionally compatible with heat pumps and condensing boilers
  • Heat distribution is even — no cold spots or draughts
  • Radiators are eliminated, freeing wall space

UFH in London Properties

Wet UFH is increasingly standard in high-specification London refurbishments — Georgian townhouses in Belgravia, new-build apartments in Marylebone, and basement conversions throughout NW3. It pairs perfectly with Heatmiser smart controls for room-by-room temperature management.
