Complete Guide to Radiant Under Carpet Heating?

Are cold feet on frosty mornings giving you the blues?

Radiant under-carpet heating might be the answer you are looking for. 

You may have thought that this cozy innovation was limited to wood or stone floors, but you can, in fact use radiant heating under carpets. 

Keep reading to discover why radiant heating is suitable for carpeted floors and uncover vital considerations to make it work for you. Prepare to turn your home into a warm, energy-efficient haven that leaves you and your feet grinning from ear to ear.

Is Under Carpet Electric Heating Possible?

One of the most common misconceptions about radiant floor heating is that many people believe it is a technology that is only suitable for wood or stone floors. In reality, radiant floor heating under the carpet is not only possible — it’s a preferred option among homeowners.

Under the carpet, electric heating not only makes carpets warm, inviting, and incredibly comfortable to the touch, but it also can provide supplemental heat to the room. 

Many people use radiant heat under a carpet as a primary heat source, mainly if it is installed in a room that rests on top of a concrete slab. 

For example, a family room built on a concrete slab may be difficult to keep warm during winter. 

Heated carpet floors add a touch of luxury to this type of room and evenly distribute heat to the space until the desired room temperature is reached.

Considerations for Radiant Floor Heating Under Carpet

Radiant heating under carpets is possible, and it is becoming increasingly popular among homeowners who want to increase their comfort while reducing their ecological footprint. However, several considerations must be made when selecting a carpet for a room with underfloor heating.

Carpet Thickness

You should be mindful of the thickness of the carpet at the time that you purchase it. A too-thick carpet may not effectively transfer or retain heat within the room.

Carpet Material

You will want to choose a carpet material that offers low thermal resistance to maximize the efficiency of the electric heat under the carpet.

Here are some suggestions for carpet materials that work well with underfloor heating:


Wool is a natural insulator that retains heat well, making it a good choice for underfloor heating. It also has good thermal conductivity, which allows it to transfer heat efficiently.


Polypropylene is a synthetic material that is highly resistant to heat and moisture, making it an excellent choice for use with underfloor heating. It is also durable and easy to clean, making it a practical choice for high-traffic areas.


Nylon is another synthetic material that is compatible with underfloor heating. It has good thermal conductivity and is resistant to wear and tear, making it a good choice for areas with heavy foot traffic.

Radiant Heat Temperature

The maximum temperature may vary based on the type of carpet that you choose and its thickness of it, but generally speaking, you should set the maximum temperature at about 80 degrees. 

As with any radiant floor heating solution, you will want to rely on a specialized thermostat to program your maximum temperature for your underfloor heating system.

Installing Radiant Heating for Basements with Carpets

When you invest in radiant heat under the basement carpet, you can also purchase different upgrades and amenities that may enhance your overall system. Some of these optional add-ons may include:

  • Insulation Boards — Insulation boards or underlays can be purchased to improve the overall efficiency of your underfloor heating carpet system.
  • Programmable Thermostat — A programmable thermostat can be purchased as an upgrade to maximize your comfort level and improve the overall sustainability of your underfloor heating carpets.

Hydronic Radiant Heat Under Carpet

Hydronic radiant heat under carpet offers several benefits, including energy efficiency, low maintenance, and quiet operation. 

Additionally, the system provides a safe and healthy heating solution that eliminates the need for bulky and potentially hazardous heating equipment. 

While the initial installation cost can be higher than other heating systems, the long-term energy and maintenance savings make it an intelligent investment for homeowners who want to create a comfortable and sustainable living space.

Closing Thoughts

In most cases, in-floor heating under the carpet is installed at the time of a renovation or during the construction process. Typically, carpet for radiant floor heat is laid after the system has been installed. However, it is possible to retrofit radiant floor heat to existing carpets.
