Underfloor heating is a revolutionary form of home heating that heats a space without the need for radiators. The system works by circulating heated water or a heated mat under your flooring, ensuring that the entire floor surface is warm to the touch and creating a comfortable ambience in the room.
UFH systems are designed to suit the specific requirements of your room, with different power output per square metre to choose from depending on the volume and heat loss characteristics of your walls, roof, windows, floors and ventilation as well as your choice of flooring material. Your UFH installer will be able to advise on the best system for your project.
The most common installation underfloor heating installers of UFH is via plastic pipes that are laid over insulation and under a self-levelling screed. These pipes are then fixed with pipe staples and the screed is poured over them, effectively burying them. The screed needs to be left to dry for up to four weeks, depending on the specific mix used.
Once the pipes are laid, the thermostat and programmer (if required) are connected to the manifold, and all electrical work must be carried out by a Part P certified/NICEIC electrician. This includes the wiring of the thermostat and programming, as well as administering the final mains connection of the underfloor heating.
Electric underfloor heating is a little easier to install than the plumbing version and can be undertaken by competent DIYers or tradespeople. However, all electrical work must be administered by a qualified electrician to ensure that the final connection is safe and complies with all electrical standards.
When choosing your underfloor heating installer, look for registered and qualified professionals who have a good track record and a wealth of experience in the industry. Ask for references and look at previous projects they’ve worked on. Also, don’t be afraid to request a written quote before going ahead with any works – this will give you a good idea of what the costs will be and can help avoid any surprises later on in the process.
Before the heating cables are laid, they need to be carefully measured up and cut. It’s important to follow the manufacturer’s instructions, as cutting or lengthening a heating cable can change its resistance rating and lead to cold spots in the floor. It’s also worth remembering that underfloor heating takes longer to heat up and cool down than radiators, so programmable controls are often recommended for busy households or holiday homes.
Electric underfloor heating mats are also available and can be installed by a competent DIYer or tradesperson, but the connection to the thermostat and programming must again be completed by a Part P qualified/NICEIC electrician. Like with the pipes, laying the heating mats properly is crucial to ensure that they function correctly and efficiently. Make sure to follow the manufacturer’s instructions and never overlap the mats or place them too close together as this can cause hot and cold spots in the room.
