Sustainable heating solutions in 2025: Discover the power of air source heat pumps and underfloor heating.

Written by

Air source heat pumps (ASHP) and underfloor heating continue to gain popularity as homeowners and developers look for more energy efficient, sustainable heating solutions. When used together, these technologies create a powerful, eco-friendly heating system that delivers both comfort and long-term savings.

Why combine Air source heat pumps with underfloor heating?

Underfloor heating operates at lower temperatures than traditional radiators, making it an ideal match for air source heat pumps. ASHP’s work is to extract heat from outside air, even in low temperatures, and transfer it indoors. This heat is then distributed evenly throughout the home via underfloor heating, providing consistent warmth without relying on fossil fuels.

This synergy offers several key benefits:

  • Even heat distribution – eliminate cold spots and enjoy uniform warmth throughout the living spaces.
  • Energy efficiency – lower operating temperatures result in reduced energy efficiency.
  • Sustainability – reduce your carbon footprint by using renewable energy sources.
  • long-term savings – cut down on energy bills thanks to highly efficient heat transfer.
What to consider before installation.

Before installing an air source heat pump and underfloor heating system, several important factors must be considered.

Floor type compatibility:

Underfloor heating is suitable for various flooring types, including tiles, stone, laminate, and even certain types of carpet. However, materials like solid wood or certain vinyls may pose challenges. UFHN consultants can help you choose the most compatible flooring and advise you on best practices. Always consult with your flooring supplier.

Property layout and space:

Underfloor heating requires adequate space beneath the floor for the installation of pipework or heating mats. In properties with limited floor depth or complex layouts, low-profile systems are available. Our experienced design team will ensure a tailored solution that fits your space without compromising performance.

Insulation and heat load:

To maximise system efficiency, proper insulation is essential. High quality insulation reduces heat loss and helps your air source heat pump and underfloor heating work to their full potential. Accurate heat load calculations are also critical; however, our experts will handle these for you.

Professional Installation: Why it matters.

Installing underfloor heating involves laying pipes or electric mats beneath the floor surface for full-area coverage. Air source heat pumps are typically installed externally, in a well-ventilated area, and connected to the underfloor heating system via smart controls and circulators.

While some may consider a DIY approach, professional installation ensures optimal performance, compliance with building regulations and system longevity. UFHN’s CSCS certified installers will ensure everything runs smoothly from design to commissioning.

Maintaining tips for long term efficiency.

Both systems are low maintenance but do require regular servicing to maintain performance:

  • Underfloor heating – periodic checks for leaks, flow issues and thermostatic accuracy.
  • Air source heat pumps require clean filters, regular refrigerant level checks, and proper airflow to function correctly.

Consider enrolling in UFHN’s service plan to keep your system running efficiently all year round. Find out more here.

Save energy, save money.

Energy efficiency is one of the most significant advantages of air source heat pumps and underfloor heating:

  • Underfloor heating operates at lower temperatures than radiators, resulting in lower energy consumption. Heating zones also enable selective room heating, reducing waste.
  • Air Source Heat pumps can produce up to four units of heat for every unit of electricity consumed— an impressive return that significantly reduces utility costs and environmental impact.

Underfloor Heating: How to pick the right system for your floor build up.

Written by

There’s a lot to love about underfloor heating. It’s discreet, energy-efficient and leaves walls free of radiators. Choosing the right system isn’t just about efficiency or cost – it’s about compatibility with the floor structure, programme constraints and overall buildup.

Let’s start with the basics: Why floor type matters!

Underfloor heating isn’t just one system—it’s a category. Within it, different types of installations are better suited to various kinds of floor constructions. The way the floor is built – whether it’s a thick concrete screed, a timber suspended floor, or something in between – will determine things like how the pipes or cables are installed, how well the system performs and how much you’ll need to raise the floor (if at all).

1. Screed Systems – The classic choice for new builds.

Screed systems are probably your go-to option if you’re working on a new build or extension with a concrete floor. Screed systems involve laying the heating pipes for wet systems or electric cables on top of insulation and pouring a screed layer.

Why people love it: Screed acts as a thermal store, holding heat well and distributing evenly across the space.

Things to consider: You’ll need enough floor depth to accommodate the insulation, pipework and screed – typically 65mm or more. It also takes a while to dry, so plan accordingly if you work to a tight schedule. Coordinating with screed installers is key, especially with underfloor heating zones, manifold positions and expansion joints. At UFHN, we offer a comprehensive package with two high-performing screed options, which means you can benefit from a hassle-free installation using us as your key point of contact.

2. Floating Floor System – Great for timber or lightweight builds.

Do you have a timber floor or work in a space where weight is a concern? Floating floor systems might be your best option. These use pre-routed insulation panels that the pipework sits in, with the floor covering floating above.

Why it works: No screed means no wet trades, so it’s cleaner and faster to install – perfect for upper floors or retrofits.

Watch out for: Ensure a capping layer is installed underneath the final floor finish. We recommend applying a cementitious board above the chosen underfloor heating system. Our team of experts can give recommendations on a project-by-project basis.

3. Low profile systems – the retrofit hero.

Low-profile underfloor heating systems are a game changer when floor height is tight—think older properties, renovations, or rooms where you really don’t want to deal with shaving off doors or raising skirting boards. They usually involve super slim boards, or overlay systems (our systems are 15-18mm) that can be laid directly over existing floors.

Why do we love it? It causes minimal disruption and doesn’t require digging up floors. It’s one of the easiest ways to bring underfloor heating to an older home. Just remember that because there’s less thermal mass, they heat up quickly but can lose heat just as fast. Also worth considering in new builds with good insulation.

4. Suspended floor systems – perfect for upstairs and period homes.

If your project has timber joists and floorboards, suspended floor systems are what you’re after. These systems run pipework between the joists, often using aluminium heat emission plates to help distribute the heat.

The upside: It’s one of the few systems that works well in older buildings or upstairs rooms with traditional timber floors.

The catch: It takes a bit more effort to install, especially if you’re working around existing floorboards, which require more cutting and routing, but it’s well worth it if done right. Make sure you insulate between the joists to avoid heat loss downwards.

Final thoughts

There is no one-size-fits-all approach to underfloor heating, but that’s actually a good thing. With the right system matched to your floor type, you’ll get better comfort, better energy efficiency, and a smoother installation process.

Specifying the right underfloor heating system isn’t just about heat output or running costs—it’s about install, programme timing, floor build-up constraints, and compatibility with floor finishes and M&E systems.

Flooring to avoid with underfloor heating.

Solid Hardwood – not recommended. 🚫

While wood is a natural insulator, solid hardwood expands and contracts with temperature changes. This movement can lead to cracking, warping, and a decrease in lifespan. If you’re set on a wooden look, engineered wood is a safer and more efficient option.

Pro’s:

  • Classic, timeless appearance

Considerations:

  • Prone to warping, cracking and shrinking.
  • Requires careful installation and maintenance.
  • It’s not as effective in heat transfer as engineered wood or tile.

Final thoughts

The right flooring choice can make a huge difference in the efficiency and performance of your underfloor heating system. Tile, engineered wood and LVT are the best choices for maximum heat transfer, while laminate and carpet can work with careful selection. Avoid solid hardwood unless it’s specifically designed for underfloor heating.

Liquid Screed: Level up your underfloor heating.

Written by

When it comes to underfloor heating installation, choosing the right screed is crucial to maximising efficiency and achieving a flawless finish. While traditional sand and cement screeds have their place, liquid screed emerges as a strong contender for modern underfloor heating installations.

Advantages of liquid screed for underfloor heating:
  • Reduce Depth: Traditional screeds require a minimum of 65mm depth. Liquid screed excels with a thinner profile – typically around 50mm when used with underfloor heating. This translates to quicker heat response and improved system efficiency.
  • Superior Thermal Conductivity: Liquid screed boasts better heat transfer properties compared to traditional options. This allows for faster heat distribution and lower energy consumption, leading to cost savings.
  • Self-levelling: No manual screening is needed to ensure a level surface for the final floor covering. This saves labour time and guarantees a professional finish.
  • Faster drying times: Liquid screed dries significantly faster than traditional screeds, allowing you to move on to the next stage of the project quickly.
  • Reduced cracking risk: Because of its self-levelling nature and minimal shrinkage, liquid screeds offer a lower risk of cracking than traditional screeds.
Considerations for Choosing Liquid screed:
  • Floor insulation: To prevent adverse reactions, ensure the insulation board used is compatible with the chosen liquid screed.
  • Drying process: Discuss drying methods. While some liquid screeds air dry, others benefit from forced drying techniques like dehumidifiers.
  • Subfloor preparation: The subfloor needs to be properly prepared before applying liquid screed. This includes ensuring a clean, level and sound surface.

Are you thinking about underfloor heating?

Written by

If you’re thinking about installing underfloor heating into a property, you can be confident that if used correctly, the system will provide many years of trouble-free operation and high levels of comfort.

Underfloor heating is virtually maintenance-free and we make sure that all the parts and components used are guaranteed for at least 50 years. That being said, propriety equipment such as pumps, valves, electrical or mechanical components are all subject to wear and failure after prolonged use. Similarly, as you would arrange for an annual service of your boiler, we would highly recommend a service of the underfloor heating system by a qualified technician.

The beating heart of an underfloor heating system.

The underfloor heating manifold is the centre of the entire system, controlling the flow of warm water to the underfloor heating pipework. In simple terms, it’s two rows of taps that allow water to flow to separate pipe circuits that are installed in different areas within the floor so they can be balanced and individually controlled.

Once the system has been installed and turned on, very little is actually needed for the operation of underfloor heating. The water temperature through the pipework is controlled by one of several methods of blending, for example, a MERCURY Control Pack, 3 or 4 port blending or a manual 3 port mixing valve. This will have been adjusted to the correct temperature at the time of commissioning and should not need to be touched. The rule of thumb about blended temperatures at the manifolds are 45°c for screeded floors and 55°c for timber suspended floors.

Close attention should be given to sensitive floor coverings such as natural wood as sustained high temperatures beyond the system design settings may cause damage. You must always check with the manufacturer for the recommended maximum temperature before installation for peace of mind.

Room Temperature.

A room thermostat usually mounted on the wall maintains the temperature at the desired comfort level. There’s a choice of control from simple dial thermostats, to programmable and even Wi-FI enabled thermostats that can be controlled from anywhere outside your home via a smartphone. Underfloor heating is usually designed to maintain a constant internal temperature of 20°c -21°c. As underfloor heating is a very stable, low-energy system, it shouldn’t be necessary to make major alterations to the temperature settings once comfort conditions have been achieved. There are so many different options on the market that it pretty much comes down to personal preference, lifestyle and budget. We supply a wide variety of thermostats from leading brands, see them here.

If you’re thinking of installing underfloor heating into a whole floor of a property then you will have what is called a multi-zone system, where each room (or zone) will have its own thermostat. This means that each room can be set at its own comfort level without influencing the temperature in other areas, keeping all the occupants in the home happy according to their own preferences.

How long should you leave your underfloor heating on for?

You will have probably already worked out that underfloor heating is a highly-efficient method of heating a property and once initial heat-up has been achieved, it should prove more beneficial to operate the system for longer periods of time, rather than switching on/off 2-3 times a day via the programmer as you might do for a radiator system.

One of the main questions we get asked is whether it’s ok to leave the underfloor heating running all day, particularly as we’re currently experiencing a cold snap and now that many of us are working from home. The answer is yes! It’s perfectly safe and actually encourages faster warm-up times and efficiency.

A feature of an underfloor heating installation is to allow economy set-back control. This means that each room thermostat can be automatically reduced by 4°c by a separate timer. It’s important to remember that this timer does not switch off the system, it only automates a set-back period overnight or during times when no-one is at home. During cooler weather, it’s a good idea to run the set-back temperature closer to your usual comfort level, keeping a constant temperature during the day if you would normally ‘set-back’ during working hours.

We look after your underfloor heating so you don’t have to.

Of course, we wouldn’t expect you to find all this out by yourselves. As an underfloor heating specialist we’ve been designing, supplying and installing underfloor heating systems for almost two decades into hundreds of residential, commercial, public, heritage and listed buildings.

If you’re looking for a quote, system design, installation or just advice, then get in touch with us to see how easy it is to install a modern heating system that will save you money on your energy bills and leave your property feeling cosy and warm.
