Underfloor Heating Systems and Sustainability:

Wet underfloor heating systems involve embedding continuous coils, or loops, of pipe work into a screeded, or timber floor, and passing warm water ­ typically at around 50° ­ through the pipe work, such that heat energy radiates upwards into the floor, and hence into the space above. Dry, or electrical, underfloor heating systems work on a similar principle, but heat energy is generated by passing electrical current through a series of heating elements ­ basic cables, ribbon cables, or mats ­ installed onto the sub-floor.

In either case, the entire surface area of the floor can be used to generate heat, so lower heat input is required to create a comfortable ambient temperature in a room, compared to a traditional radiator system. Unlike a traditional radiator system, which heats the unoccupied space immediately below the ceiling of a room first, underfloor heating provides warmth from the floor upwards, such that a more natural temperature gradient exists, and a lower air temperature ­ typically 2°C lower ­ is required to maintain a comfortable temperature. This means that underfloor heating can provide an economical, and environmentally friendly, solution for the whole of your home, although it can, of course, be combined with other forms of heating ­ traditional radiators, or electrical storage heaters, for example ­ to provide "targeted" heat, as and when required.

Low heat input, of course, means lower fuel bills. Modern, highly energy efficient boilers ­ condensing boilers, in particular ­ multilayer pipes, control systems, and technology that, generally, requires less electricity than ever before, makes underfloor heating a natural choice for environmentally aware consumers. Not only is heat produced, and distributed, more efficiently by wet or electrical underfloor heating systems than by traditional radiator systems, but an absence of convection currents in the air of your living space means that dust, dust mites, and other allergens are not circulated. This can help to produce a healthy, hygienic environment for sufferers of allergies or respiratory ailments.
