What is UFH?

Underfloor Heating is one of the most widely used systems for heating domestic and commercial properties. Its growing popularity can be put down to a number of key lifestyle and operational benefits such as comfort, economy, flexibility and its virtually maintenance free operation.

The system works by circulating low temperature water, normally between 35-55°C, through loops of plastic pipe work which are embedded within the floor structure. This effectively turns the whole floor area into a low surface temperature radiator. Warm water is then distributed to the pipe work laid within the floor from a manifold which is best positioned in a convenient central location such as under the stairs or in a cupboard. The John Guest Underfloor Heating system can be installed into most floor types and can be used with most floor coverings.

A radiator system lacks total efficiency as it transfers energy into the room largely by convection. This convection results in the floor being the coolest part of the room and leaves a mass of warm air at ceiling level.

Alternatively, an Underfloor Heating system heats a room mainly by radiation. This is considered the most natural and comfortable form of heating - just like the sun. Radiant energy emitted by the floor is partly reflected by each surface and partly absorbed. Where it is absorbed, that surface becomes a secondary emitter. After a while, all surfaces become secondary emitters. Furnishings themselves radiate energy and the room becomes evenly and uniformly warmed. The energy reaches into every corner of the room - no cold spot, no hot ceilings and no cold feet.
