Underfloor heating top tips

Martina Valve from Warmup (warmup.co.uk) offers advice on making the right choice

● Think thickness Previously fitted only in new homes and extensions, the availability of ultra-thin electric mats and wet systems that only raise the floor height by a few millimetres, means that owners of older houses can now also enjoy UFH throughout their entire home.

● Check restrictions Listed buildings may have special conditions in place, so if the work would affect the house’s character, you must apply for listed building consent along with any required planning permissions or building control approvals.

● Choose the best thermostat UFH is controlled using a thermostat that provides precise room temperature control. Smart thermostats, such as the 4ie Smart Wifi model, help keep your energy bills in check, so investigate the different options and choose one that suits your lifestyle.

● Calculate the heat loss UFH can be used in any room. The key is to ensure that the heat output of the system is higher than the heat loss of the space. Before purchasing, get a heat loss calculation done to ensure the system can deliver enough energy output. Adding insulation boards improves the system’s efficiency while reducing heat loss. You should look to improve insulation as much as possible.

● Design the right system The type of system that is suitable for your home will depend on the nature of your project and your personal preference, but you should keep in mind that sometimes connecting piping to the existing heat source in older homes may not be as straightforward as in modern properties. The system should be carefully designed.

● Choose flooring wisely A floor covering’s suitability for use with UFH lies in the thermal conductivity of the material – meaning how quickly and efficiently heat transfers through the floor to the surface. Tile, stone, carpet, wood and luxury vinyl tiles can all be used with UFH, but some products must not be heated above 27 degrees celsius. You should always check with the manufacturer that your chosen flooring is suitable for use with the system.
