Underfloor Heating

A better kind of heat
Underfloor heating works by circulating warm water through a series of continuous pipe loops fitted underneath your floor. The pipework creates a large radiant surface which heats your home from the floor upwards. This radiant form of heating is very different to the convected heat provided by radiators. Radiators work by drawing cold air across your floor, heating it and then convecting it upwards towards the ceiling. The use of radiant heat rather than convected heat will provide you with a number of significant benefits.


Natural, comfortable warmth
The main advantage of underfloor heating is its high level of performance. Radiant heat means that the warmth is concentrated where you need it most. Room temperatures higher up are usually around 2°C lower than at floor level. So it’s perfect for human comfort - you won’t get cold feet and you will keep a cool head! It’s highly controllable heat too. You can make each room a separate zone, varying heat output according to the time of day and location. You’ll enjoy uniform heat even in the largest rooms, with no cold spots and no draughts caused by air circulation. It’s even good for furniture, with its gentler, more even heat and smaller variations in humidity!

Radiater Output compared to Underfloor output

Underfloor output compared to radiator output


The Purmo Radiators available from Heating Supplies are used in various applications throughout the house or commercial facility, from standard radiators to bathroom feature items. From traditional to designer.

Systems can be run from a variety of heat inputs and through use of the supplied control systems can optimise heating based client needs.

Advantages of radiators over underfloor heating is that it can be more easily retrofitted to existing buildings and that the heat up time from cold is much quicker. Again as with underfloor heating there is no noise associated with the heating system and the comfort level is higher than fan forced systems.
