Underfloor Heating Underfloor heating systems operate by distributing warm water throughout your home via a blanket of polyethylene pipes embedded in the floor. Radiant Heat Ltd uses the highest quality 17mm double cross-linked polyethylene pipe  produced by one of the major pipe manufacturers in Sweden. PE-Xb pipe is both strong and extremely flexible, and has a built in oxygen diffusion barrier. Our pipe is covered by a 25 year guarantee against manufacturing defects. Our manifolds are stainless steel.  Instead of fitting high temperature metal panel radiators on the wall, Pex pipes are laid in the floor and warm water is circulated through these pipes, turning the whole floor area into a large radiator.  Since the floor area is so large compared with a radiator, it can run at much lower temperatures.  In order to achieve these lower water temperatures, the pumped high temperature water from the boiler is mixed to the design temperature just before the manifold using the Radiant Heat mixing valve and variable speed pump.  The warm water is then pumped through the Underfloor system. Why choose underfloor heating? Comfort - The entire room is warmed with an even distribution of rising heat. Health & Safety - Danger of injuries on radiators expelled, heated floors hinder the growth of dust mites. Money Savings - Heating bills may be reduced by as much as 25% and the system being virtually maintenance free. Design Freedom - Almost any flooring can be used and without radiators you have the freedom to design your environment as you please. Environmental - Increased heating efficiency reduces fuel consumption and is therefore more environmentally friendly.
