Things To Consider When Installing Underfloor Heating

Is there a more luxurious feeling than coming home at the end of a chilly day, taking your shoes and socks off and sinking your feet into a warmed floor? Well, electric underfloor heating is one great way to get that feeling. You might think that adding underfloor and electric underfloor heating would cost you an arm-and-a-leg, but it doesn’t have to. If you shop around and go with the right supplier, find a good installer or even go the DIY route, installing underfloor heating in one, or several, rooms can be within reach of a lot more of us.

Underfloor heating can be fitted to new and old homes alike, so if your home didn’t come with it, you can build it in. Nearly all electrical underfloor heating systems can be fitted into an existing subfloor, but which is right for you will depend on your heating needs and subfloor.

Refitting Underfloor Heating

If you are adding underfloor heating to an existing room or central heating system this is known as retrofitting. You are adding a system to an existing floor and room, rather than fitting it into a new build. Electric underfloor heating is best suited to this type of project.

Adding underfloor heating is a big job and will involve a bit of disruption so before your get started and plan a life with warm floors, you need to think about your existing flooring and room as a whole. Projects like this are best done as part of a larger renovation project for room or home. Existing flooring will have to be removed. If you have tiles these may be damaged in the process so it is worth thinking about whether you want to remove them or not. You may also need to think about adding insulation boards and installing the heating system on top of these, preventing heat loss. The new floor covering would go on top of these new layers. Thankfully underfloor heating generally doesn’t visibly raise the height of your floors, it does however often mean replacing them.

Things To Consider When Installing Underfloor Heating


1. Your existing heating system

Do you use storage heaters or does your home already have central heating? Are you replacing an entire system across your whole home, or a single room? If you already have central heating and are looking to retrofit a single room you can run your underfloor heating off this. You can pick up a single zone kit, like the Nu-Heat’s OneZone™ – this can be quickly and easily integrated into your existing central heating. You can install UFH in just part of your home, if you are renovating a kitchen or bathroom, and it can be mixed through parts of your property. Even installing it in part of your home can reduce your energy usage and bills.

2. Is UFH Cheap To Run?

The simple answer is yes, underfloor heating is a relatively cheaper way to heat your home. Today there are UFH systems which heat up as quickly as your radiator, providing quickly heated rooms and a much more consistent warmth across the room. Depending on the system you use UFH could reduce your heating costs, though it is debatable whether you will make your money back on it. Pairing UFH with a new condensing boiler will maximise your chances of reducing bills.

3. Will UFH Work With My Flooring?

Underfloor heating and electric underfloor heating work with most types of flooring. As previously said do bear in mind that exisiting flooring will have to be taken up in order to lay the heating system so if you have tiles or similar ceramic floors, you will probably need to replace these. UFH will work with most types of flooring;

  • Ceramic tiles, slate and other stone floors
  • Treated hardwood floors
  • Carpeted floors – here you will need to install a low thermal resistance underlay and hessian backed carpet
  • Linoleum & vinyl floorings.

4. How Can I Make My UFH More Efficient?

To get the biggest benefit from UFH you need to make sure you install the right type of subfloor insulation. This means that the concrete or plywood base which you install your heating on needs to have additional thermal insulation. Specially designed insulation boards or underlay will give your heating system the best performance and best transfer heat through the underlay to the carpet and through to your room.

Installing the heating system itself is relatively quick, easy and without too much hassle, once the original floor is up. However, it is important to ensure that any workmen you hire or you yourself have the relevant qualifications or experience to take on the job. If you are looking for DIY electric underfloor heating there are several brands and systems on the market.

To find out which is best for your home, budget and needs it is advisable to pop into a DIY or specialist store and discuss the options available on the market. If you do buy a kit to install yourself make sure it comes with everything you need, including primer, insulation boards (if necessary), cable, and thermostatic controls.

  1. Underfloor heating is so beautiful – even though you can’t see those lines and curves under your floorboards! Just like seat heating in cars, it’s a little bit luxurious even though it’s subtle. It’s fantastic to use a style of heating that’s so old – it’s practically Roman! – and doesn’t involve unsightly radiators – paint them up as much as you like but they will never really look right!

  2. Can anyone tell me how does underfloor electrical heating compares to regular central heating with a gas boiler? Is the cost of such electrical heating lower than the cost of gas or gas is always the cheapest option?

  3. I recently had underfloor heating installed under my concrete flooring, and because it’s a small space it’s really worthwhile.

  4. Nice post. Thanks for sharing this post.

  5. I’ve underfloor heating and I’m extremely pleased.

  6. Insulation acts as a barrier to heat loss and heat gain, particularly in roofs and ceilings, walls and floors.

  7. This was an excellent article, thanks ever so much for sharing this.

    I work with a number of handymen in London and they are huge advocates for underfloor heating compared to conventional options.

  8. Great post! Thanks for sharing.
