Cost of Underfloor Heating
Underfloor heating guide and prices
Underfloor heating is becoming a popular alternative to conventional radiators, especially so in luxury bathroom renovations, but also popular in many new build houses as the primary source of central heating. Underfloor heating can be installed under almost any type of floor including stone, wood, tiles and even carpets. There are two different types of underfloor heating, electric (dry system) and water (wet system). Electric systems are cheaper as they are easier to install and can even be done as a DIY project, whereas the installation of a wet system is a lot more involved, so usually reserved for new build properties or as part of a larger renovation project. But, electric systems are by far the better choice for retrofits to existing properties.

Underfloor heating things to consider
Wet systems are only really suited to new-build homes or major refurbishments as they require extensive piping all around the house which has to be connected back to your central heating system. All floors will need to be removed and the extensive labour involved will be very expensive. But when installed in a new build home, the labour cost for the installation is much less. Electric underfloor heating running costs are higher than wet underfloor heating systems, but they are much cheaper to retrofit and they do still warm the floor giving a luxurious feel, but they are not so good at heating the entire room, especially if a bigger room, but are usually fine with smaller rooms such as a bathroom.
If you have an older house with larger rooms which already tends to get cold during the winter months, then electric underfloor heating may not be able to produce enough heat to make the rooms comfortable. Wet underfloor heating systems have much more power as they are hooked up to existing boilers, so they can completely replace the radiators and still warm the rooms to a comfortable level.
Doing it Yourself
Wet underfloor heating systems are really not DIY friendly. Installing them will at the very least require some assistance from a plumber or heating engineer. With a system which is connected to your main boiler, it’s simply not worth chancing it and doing it on your own, so always consult a local heating engineer or underfloor heating company to advise you before taking on this job. A survey carried out by a professional will help you select the best underfloor heating system and ensure your boiler can support the additional heating system. But DIY electric underfloor systems using heat mats are much simpler and cheaper to install. You will still need an electrician to connect the power up to your heating system, but for a typical bathroom, the total cost for DIY electric underfloor heating can be under £500. For those who are very confident in their skills, there are also DIY wet underfloor heating kits. These full kits include a pump, valves, thermostats and pipework to heat around 20 square metres. If you did most of the work DIY and just hired a plumber or heating engineer for the important bits, you could have a wet underfloor heating system in your bathroom for under £1000.

I want to replace a normal radiator with an underfloor heating system in my kitchen. I also would like to renew two old radiators for new ones. Remove a sink and replace in a different location with a new one. Believe I have most of the equipment required.
