Are Rugs Suitable for Underfloor Heating?

The inviting warmth of underfloor heating paired with the softness of a beautiful rug can transform any room into a cosy haven. But, can rugs be safely and effectively used over underfloor heating? Let’s unravel the mystery.

A lower tog rated rug will let more heat through.


If you're wondering if you can use a rug over your heated floor, the answer is an encouraging yes, with a few considerations. While it's true that a rug can introduce an extra layer of insulation, potentially hampering heat transfer from your underfloor system to the room, not all rugs are created equal. Selecting the right thickness, material, and size can keep your heating system efficient and your floor covering undamaged.

For those who have underfloor heating installed, we can guide you through the process of selecting a rug that not only complements your décor but also harmonizes with your heating system.

Remember, some floor coverings like engineered wood have a temperature limit, and surpassing that limit can cause damage. This issue is more prevalent with electric underfloor heating than warm water underfloor heating systems. A heavy rug with high thermal resistance can create 'heat spots', potentially causing warping and damage to your wood flooring.

So, what is the ideal rug for underfloor heating?

Firstly, consider the thickness. A thick rug can trap heat and impede its release into the room. Try to choose a rug with a tog rating of 2.5 or less for optimal heat transfer.

Next, take note of the rug material. Synthetic rugs may not be designed to withstand or transfer heat efficiently and could even suffer damage if exposed to excessive heat for an extended period. We recommend rugs made from natural materials such as wool, which are more resistant to heat.

Also, the underlay material is significant. Felt or polyurethane underlays are poor heat conductors and could reduce the efficiency of your heating system. Rugs with hessian underlay are preferable.

Furthermore, the size and position of your rug matters. It is advisable to choose a rug that is not too large, so your underfloor heating system can warm up the room quickly. Small rugs or bath mats are useful in bathrooms with underfloor heating systems, providing comfort and warmth after showers during the colder months.

When it comes to different flooring types, tiles are more heat-resistant than wood, making them ideal for underfloor heating and rugs. Wooden floors, particularly engineered wood, can also work well with underfloor heating, but care must be taken in choosing the right rug materials to avoid damage. Laminate floors offer versatility, and like hardwood floors, they can be used with rugs and underfloor heating provided you adhere to the manufacturer's guidelines regarding temperature limits.

In conclusion, finding the perfect rug for your underfloor heating system can be a smooth process with the right information. Our advice: choose rugs made of natural materials, with a low tog rating, a hessian underlay, and of a size that doesn't overly insulate the heat provided by your heating system.
