If you’re thinking about adding underfloor heating to a new part of your home such as a conservatory or extension, you’ll want to look into costs before you do so.
Here we take a look at costing and also the benefits of installing such a system.
What are the advantages of underfloor heating?
There are plenty of perks to having this form of heating. Comfort has to be one of the key ones. No more walking on cold floors – instead you can walk barefoot through your extension in winter and still have warm feet.
Additionally, they can help you save on your heating bills. The amount of radiant heat offered by underfloor heating makes it more pleasant to have than radiators. Since the pipes for the heating are usually set into the screed under the floor, it takes far longer for them to cool down once the system is switched off too. This is beneficial because you’ll still be able to benefit from the heat coming through the floor.
It is also less common to experience problems or leaks with a properly-installed system. This compares favourably to the prospect of a leaking radiator that might end up ruining your floor.
Cost per m2 to install
If you are looking to install underfloor heating in an existing property, the cost can be prohibitive. The system is much easier and cheaper to install in a new build, because it can be put in as the floors are going down.
Additionally there are two systems to choose from – electric underfloor heating, which is cheaper, and water underfloor heating. The latter is better but more expensive. Your boiler will pump water through the pipes and heat the floor and the room itself over time. Conversely, electric systems only heat the floor and are not ideal for a proper heating solution.
As for costs, they vary depending on who you go to. We’ve found quotes starting from around £14 per square metre for electric underfloor heating. You will pay more to have someone install it for you. This doesn’t include the cost of any insulation you might need.
Conversely, water-based systems will cost more. You can expect to pay upwards of £36 m2 here, and as much as £48 m2. Your actual cost will therefore depend on the complexity of your requirements, the size of your room/home and the company you choose to fit whatever system you want to add. Remember though, if you want proper heating for the room, choose the water-based system and not the electric one.
Don’t forget the running costs
It’s not just the installation costs you have to bear in mind when you are considering having underfloor heating. You also have to think about the ongoing costs of using the heating.
It is very difficult to provide an accurate idea of how much your system will cost to run. Are you in a well-insulated new build or an older property where the underfloor heating has been retro-fitted? The quality of the doors and windows in your property, and how good they are at retaining heat, will also come into play, as will many other elements. It will obviously also depend on how much you are paying for your heating bills.
A water-based system will provide better heat for your home than an electric-based one, which only heats the floor. Once you have taken into account the cost of having the system installed, you have to think about the pros and cons of getting it in the first place. This is why having it fitted during a new build or extension is usually best, as it can reduce the overall costs.
In terms of electric systems, estimates of around 4p per hour per square metre have been provided as estimates. Another source revealed that if you have a gas boiler, the cost of running a water-based system should be akin to that of having radiators.
In short, while the cost and upheaval of having a water-based underfloor heating system put in might put you off going down this route, you will get underfloor heating that will heat the rooms as well as the floor. Electric underfloor heating might seem easier, and you could even lay it on your own with basic knowledge, but your electricity bills will go up and you still won’t heat the rooms – only the floor.
As you can see, the overall costs should be considered and a range of quotes should be sought before making any firm decisions on which way to go.
