Underfloor Heating

The Right Flooring for Your Underfloor Heating

Underfloor heating is a luxurious and efficient way to heat your home. It distributes warmth evenly across rooms and eliminates the need for bulky radiators. However, not all flooring options are suitable for this type of heating system. The key to maximizing the efficiency of your underfloor heating lies in selecting the right type of flooring. Here, we explore various flooring options, focusing on their compatibility and performance with underfloor heating systems.

Carpet and Underlay

When it comes to carpeting, the total tog rating of the carpet and underlay combined is crucial. Research from the Underfloor Heating Manufacturers Association (UHMA) and advice from The Carpet Foundation indicate that for underfloor heating systems to operate efficiently, the combined tog rating should be less than 2.5. This ensures that the carpet does not act as an insulator and prevents the heat from penetrating through to warm the room effectively.

Many carpet manufacturers pre-test all their carpets, providing them with a tog value rating to ensure compatibility with underfloor heating systems. A tog value of up to 2.5 for both carpet and underlay combined is considered optimal, allowing the heat to pass through efficiently. For the underlay, it's recommended to select options with tog values of less than 1.3.

Luxury Vinyl Tile (LVT)

Luxury Vinyl Tile (LVT) is another excellent choice for rooms with underfloor heating. LVT is designed to be compatible with underfloor heating, ensuring that homeowners can enjoy the warmth without worrying about the warping or cracking that can occur with some natural flooring materials. Before installing an LVT floor, it's essential to ensure that the underfloor heating system has been properly installed, commissioned, and is working without leaks. This preparation guarantees that the LVT flooring will perform well over the heating system.

Wood Flooring

Engineered wood flooring is more suitable for underfloor heating than solid wood because it can handle changes in temperature and humidity better. The construction of engineered wood allows it to expand and contract without warping. It's important to choose engineered wood with a suitable thickness and to ensure it's laid correctly to facilitate optimal heat transfer.


Selecting the right flooring for your underfloor heating system is vital for comfort, efficiency, and the longevity of both the flooring and the heating system. Whether you prefer the softness of carpet, the elegance of LVT, the natural beauty of ceramic tiles and stone, the warmth of engineered wood, or the practicality of laminate, ensure that your choice is compatible with underfloor heating. By paying attention to tog ratings, thermal conductivity, and manufacturer guidelines, you can create a cozy and welcoming environment in your home that is both stylish and efficiently heated.
