Can I Put a Rug Over Underfloor Heating?


Underfloor heating provides a lovely warm surface on which to walk barefoot at home. Many people want to combine this with a rug for added comfort, but wonder if rugs and underfloor heating are compatible with each other.

You can put a rug over your underfloor heating, but you need to use the right types of flooring and rug material. A thinner rug with a hessian base, rather than felt, is recommended. Larger and thicker rugs reduce available heated floor space and may become damaged or even pose a fire risk.

Can I Put a Rug Over Underfloor Heating?

Underfloor heating energy helps increase the floor’s temperature, and ultimately, it also helps keep the entire house warmer. If you must lay a rug on your electric underfloor heating energy system, you must know that the rug may lower the electric underfloor heating system’s effectiveness.

There will be less floor space from which heat can radiate.

Types of Rug and Flooring to Avoid with Underfloor Heating

There are different types of rug materials with unique insulation levels. The electric underfloor heat’s effectiveness might not be felt with a thick, high insulative rug material such as synthetic components or rugs with high thermal resistance.

Do not use synthetic rugs because they can melt when they are in contact with high-temperature regions for too long.

Some floor materials tend to more conduct heat from beneath and reach a higher surface temperature, wooden floors being an example. You should not place a rug over a solid wooden floor overlying an underfloor heating system.

The rug will trap excess heat in hot spots and be in danger of becoming damaged or even melting. Your wooden floor will heat up beyond it’s maximum recommended temperature and the boards may ‘cup’ or ‘twist’. These problems are fire hazards. Combining a solid wooden floor and a synthetic rug will maximise the risk of this happening.

You just need to check with your flooring store staff for their advice on whether your chosen rug (and floor type) is compatible with underfloor heating.

So, yes, you can put a rug over your electric floor heating. Ensure that your preferred rug material is not too large, as this can reduce the overall effectiveness of the heating system; also, ensure that the rug is made from high-quality natural fibers to enable it to withstand the high temperature of the flooring.

Can I Put a Rug Over Water Underfloor Heating?

You can put a rug over your water underfloor heating system. Since the water underfloor heating method is a very effective choice for home heating, you might be wondering if you need to compromise on your rooms’ overall heat quality, hoping that the rug won’t hinder your eventual heat transmissions.

However, before you decide to put a rug over your underfloor heating, ensure that your flooring is compatible with your choice of underfloor heating system.

The above advice about rug and flooring types to avoid should be adhered to. Tiles and stone kinds of flooring are best used with water underfloor heating systems due to their increased conductivity and heat diffusion.

Also, ensure that the kind of rug to be placed on your floors is made from high-quality materials. The lesser the thickness, the faster the heat gets into the room and the house eventually. A thicker rug will have you waiting for a long time until the temperature is risen and diffused.

So, before you put your rug over your water underfloor heating, ensure that your flooring is either stone or tile; also, ensure that the rugs are not too thick to reduce underfloor heating energy consumption. Once you’ve checked this, you’re good to go.

Can I Put a Rug Over Electric Underfloor Heating?

You can place a rug over electric underfloor heating but you still need to ensure you use a flooring type and a rug that is compatible with a heated floor. The same safety points above apply to electric underfloor heating systems.

You need to avoid rugs with wooden floors and the rug you use should be thinner, hessian based (rather than felt) and have a low thermal resistance (TOG).

Is it Safe to Use a Rug with Underfloor Heating?

It is generally considered safe to use a rug with underfloor heating as long as you use the correct types of rug and flooring, and check the compatibility with flooring professionals. However, you should note this is not a completely risk free addition to your home, as it is difficult to guarantee that the rug won’t become damaged by the radiant heat.

Both electric underfloor heating systems and water underfloor heating systems are compatible with rugs, irrespective of the system you have installed. The type of rug and floor material are what is important.

To use a rug conveniently with your underfloor heating energy use, you should ensure that your rugs are not too thick. Having rugs of great thickness could create a blanket effect by not allowing the easy transmission of heat between the floor and the entire room.

Increased thickness in rugs will eventually translate to a higher cost of keeping your rooms warm due to increased underfloor heating energy consumption.

The size of your rug also matters a lot. Rather than get large-sized rugs that would cover a wide area, it is more advisable you go for smaller rugs. Small rugs would allow the even distribution of heat and prevent the floors from overheating. The possible risks to avoid in this scenario are to avoid using low-quality rugs that could deter the heat transmission between your flooring and the room.

You could always try and position your smaller rug in an area in which is not supplied by your underfloor heating, or where your underfloor heating panels have failed. This is a way that you can get around any patchy underfloor heating problems you have.

Which floor surfaces should you not use a Rug with Underfloor heating?

In case you do not know, certain floor surfaces are not ideal for the kinds of flooring compatible with using a rug on underfloor heating. Thick wooden and timber floors aren’t ideal floor choices for underfloor heating except in cases where the floor is engineered timber that has been designed to meet the required temperature and thermal compatibility.

A better type of flooring for Underfloor Heating

The most ideal floor surfaces for underfloor heating will be stone flooring or tile flooring. These kinds of floorings have a high conduction rate, which allows them to diffuse heat faster than the regular floors.

You are good to go as long as the rug you choose is compatible with the type of flooring: In cold seasons, rugs can be used on tiles and stones as they are both better conductors of heat and will allow efficient transmission between the underfloor heating system and the surfaces.

Stone or tile floors can be pretty cold to walk on in the winter so rugs can offset this problem when you’re not using the heating system.

Suppose you also intend to optimize underfloor heating energy consumptions in your home. In that case, you should try to avoid using thick wooden floor surfaces in your home as they will further increase the cost of heating and make the available heating inefficient.

Will Underfloor Heating Cause Problems with the Rug Itself?

Underfloor heating can cause problems with the rug itself only when the rug is made of synthetic fiber or low-quality materials. In cases where the rug is made from synthetic fiber, it causes a reduction in material quality, and in severe cases, the rug begins to melt.

The melting of the rug is triggered by the prolonged exposure of the synthetic rug to the heat from the underfloor. High temperatures tend to have a damaging effect on the physical properties of synthetic materials, such as tearing or melting. So, underfloor heating will not cause problems to your rug as long as the rug itself is made from high-quality materials.  

If the rug is made from low-quality materials or has a thick texture that isn’t heated permeable, molds are most likely to be the problem you’ll face, especially if the rug is in a place that allows it to absorb a lot of moisture.

You should ensure that your rugs are recommended to suit your kind of flooring surface and the method of heat energy source. Investing in high-quality rugs will get you increased comfort and warmth.

Do Rugs Reduce the Effectiveness of Underfloor Heating?

Your underfloor heating might not be as effective as it should if you do not get the kind of rug that is compatible with your underfloor heating and the floor surface. If you get a rug that isn’t exactly best for your home, it may end up causing a blanket effect by obstructing the heat passage and transmissions. Most floor types have specific temperature and thermal conductivity properties; using an incompatible rug type might not be an ideal choice for you.

The most compatible rugs for underfloor heating energy use should be Hessian rugs with minimum thermal resistance. The rugs must have a considerably ideal size and thickness for overall effectiveness in heating the room. Try to avoid thick and heavy rugs with a high thermal resistance level; this can cause heat spots on wooden floors and molds. Also, look out for compatible floor types and rug selections when you try to get a new rug for your rooms.

Finally, only get rugs that match the thermal conductivity settings for your underfloor heating systems and floor surfaces. This will ensure that your rug further compliments the heating conditions of your room.
