All you need to know about installing underfloor heating for your home including costs of materials, labour and time frames.
Underfloor heating can be installed under almost any type of flooring and is a modern and luxurious alternative to a conventional central heating system with radiators. This type of heating can bring an unrivalled level of warm comfort to your home and is available in two different types: Electric underfloor heating (dry systems) and Water underfloor heating (wet systems). Electric underfloor heating is usually cheaper and easier to install and can be done as a DIY project. Though the running cost of this type of underfloor heating system is generally higher. Whereas water underfloor heating (wet systems) is a lot more involved, way beyond the scope of the DIY enthusiast and usually reserved for new-builds. However, as they are plumbed into existing boiler systems, they cost much less to run.
The total cost of installing an underfloor heating system will be dependent on the area to be heated (whether a room or entire house), the system type (wet or dry system) and the groundwork required. Electric underfloor heating systems use a network of electrical wires running under the surface which warms the floor but does not heat the room very efficiently, so are best installed in smaller rooms (great in bathrooms for example). Different models of electric underfloor heating systems are available including heating mats which are the easiest to install. Wet underfloor heating systems can also work with different flooring types, but the installation is a lot much more involved and they are best suited to larger areas or for use as heating in entire homes.
Water underfloor heating use pipes to run hot water from a boiler through the floor and into the room. These wet underfloor heating systems are far more efficient than conventional radiators but are more expensive to install. Wet systems are ideally suited to new-build luxury homes as the retrofit costs will be even greater. Wet systems are definitely not DIY friendly as they will certainly require professional assistance from a heating engineer or underfloor heating specialist. If considering underfloor heating, then a professional survey should be carried out to help you select the best type of underfloor heating for your home, budget and circumstances.
Underfloor heating installation costs vary depending on the area to be heated and the complexity of the system. Whichever underfloor system you choose, the floor will need to be removed before the system can be installed, but electric systems are much less hassle and the preferred option for retrofits as they don’t require extensive pipework. Typical costs for electric/dry underfloor systems are around £60 per m2 when using electric heat mats, rising to over £100 per m2 for wet underfloor heating systems, with whole house system installations costing £2,500+.
The average rate a professional underfloor heating specialist is typically around £200 per day. The total labour time is ultimately dependant on if wet or electric systems are installed. Wet underfloor heating will take the longest as pipework is required and will take around 4 days to complete. Electric underfloor heating is the quicker option and is expected to take around 2 days to complete for your entire home.
