Underfloor heating is a way of heating a home through strong and flexible tubing that is embedded in the floor. It is efficient and affordable, offering numerous advantages over radiators.
There are various types of underfloor heating systems available. The best underfloor heating solution for you will depend on a range of factors including your project type, your current heating system and energy source.
- Suitable for most properties
- Maximises space in the home
- Luxurious feeling of warm floors
- Flexible control through zoning areas of the home
Underfloor heating essentially works by turning the floor area into a giant, efficient and invisible heat emitter. Heating tubes or cables are installed beneath the floor, which heat up, to warm the room from the ground up. Strong, flexible tubing is used for warm water underfloor heating systems, whilst cables are used in electric underfloor heating systems.
Because underfloor heating covers such a large surface area, it is able to use much lower water temperatures than radiators. This helps to improve efficiency – especially with a heat pump – and also better heats a room as there are no cold spots.

Compare Underfloor Heating Systems
|UFH system type||Project suitability||Running costs||Installation costs||Installation time|
|Warm water/wet underfloor heating||Suitable for all types of project including new build, renovation and single areas||Low long-term running costs||Higher upfront cost than electric UFH but much cheaper to run||Varies depending on project size and UFH system|
|Electric underfloor heating||Recommended for smaller spaces, like a bathroom, due to running cost.||Around 3x more than warm water underfloor heating||Generally cheaper to install||Install in a single room in just a few hours|

Yes, underfloor heating is extremely versatile meaning it can be used with a wide range of fuel types. You can pair your UFH with an air source heat pump or a ground source heat pump for a more environmentally-friendly solution. If this isn’t an option, you can also use UFH with oil, Liquid Petroleum Gas (LPG) and other off-grid fuel boilers.
No. If you are renovating, you don’t need to dig up your floors to install UFH!
There are various different systems and installation options, including low profile overlay solutions, like our LoPro® range. These are simply installed over existing solid or timber floors. Your choice of tiles or laminate can then be laid directly over the system.
How you control your UFH depends on the type of system you have. Screed UFH is usually left on with a setback temperature. This helps the concrete slab to act as a thermal store, avoiding long heat up times and keeping running costs low. Retrofit UFH heats up and cools down quickly, so can be controlled more like a radiator system.

It’s incredibly unlikely that the system will leak.
Our Fastflo® heating tube is strong and durable, manufactured in line with the highest European Industry Standards. This is covered by a 50 year warranty with the first 10 years being insurance backed, covering complete cost of any remedial works and reinstatement in the very rare event of a manufacturing fault.
We also design systems so that the tube only ever connects at the manifold – there are no joins under the floor whatsoever – meaning there are no weak points where leaks can occur.
This depends on the size of the property and the most suitable underfloor heating system for the project. Underfloor heating is around 25% more energy efficient than radiators – it can actually save money on your heating bills. For more information, including average prices per m², see how much underfloor heating costs to run.
Underfloor heating can be used under most floor coverings, including carpet, tiles, engineered wood, vinyl and laminate flooring. If you’re unsure check the suitability with your flooring supplier. Read more about the best floor coverings for UFH
Does underfloor heating warm rooms up faster than radiators? Retrofit underfloor heating that sits on top of the floor warms up very quickly, on par with a radiator system. UFH that is set within a screed can take longer to heat initially, but retains its heat for longer and is easily programmed to provide the right amount of heat exactly when needed.
Underfloor heating is usually installed by a plumber or a Nu-Heat Registered Installer, but some DIYers choose to fit most of the system themselves, with signoff from a qualified plumber and electrician, as our manuals are fully comprehensive. The specific installation steps vary depending on the system. Find out how to install UFH.
UFH can replace radiators completely, or work alongside them, depending on your type of property. New builds are ideal for installing underfloor heating throughout – it’s 25% more energy efficient than radiators. UFH can also be installed on all floors of your renovation property.
As with any heating system, if the property is poorly insulated it will require more energy to keep it warm. We would always recommend improving insulation if this is possible, as this helps to create a more efficient system that keeps running costs low.
When retrofitting underfloor heating, it’s often not necessary to add insulation to a concrete slab as downward heat loss is minimal. If, however, you will be installing UFH over a suspended timber floor with a void beneath it, insulation is absolutely essential.
When designing your bespoke UFH system, we take into account your property’s construction, insulation and glazing levels to ensure the system will perform.
Our ultimate guide to UFH and insulation offers further information.
Our UFH tubes come with a 50-year product warranty, with the first 10 years insurance backed to cover any remedial works. Underfloor heating manifolds have a 10-year warranty, while electrical and plumbing components have 2-year warranty.
If you’re adding underfloor heating to your existing central heating or radiator system, you will need a separate thermostat for UFH. However, our underfloor integrates with an existing system, or you can control your UFH and central heating together by fitting a radiator manifold. We offer a wide range of underfloor heating thermostats, from standard dials to smartphone-controlled wireless models.
Underfloor heating is safer and healthier than radiators, as exposed hot surfaces are hidden and dust traps removed. They offer a controlled and comfortable heat source, helping to eliminate draughts and cold spots in your home.
