If you’re considering installing hardwood flooring in a home with radiant heating, you may be wondering whether it’s possible to do so without causing damage to the flooring. The good news is that hardwood flooring can be installed over radiant heat, but there are some important things to consider to ensure that your flooring performs well and lasts for many years.

What is Radiant Heating?

Radiant heating is a method of heating a space by warming the floors, walls, or ceilings. It works by circulating hot water or electricity through tubes or wires that are embedded in the flooring, which then radiates heat throughout the room. Radiant heating is known for its energy efficiency, as it can reduce heating costs by up to 30%.

Installing Hardwood Flooring over Radiant Heat

When it comes to installing hardwood flooring over radiant heat, there are some special considerations to keep in mind:

  1. Type of hardwood: Engineered hardwood flooring is the best option for installation over radiant heat because it is more stable than solid hardwood and less prone to warping or buckling. Choose a hardwood flooring option that is specifically designed for use over radiant heat, and make sure that the manufacturer’s recommendations are followed during installation.
  2. Moisture content: The moisture content of the flooring must be between 6% and 9% before installation. This is especially important when installing over radiant heat because the heat can cause the moisture content of the hardwood to change, which can lead to warping or buckling. The hardwood flooring should be allowed to acclimate for at least 72 hours before installation.
  3. Subfloor: The subfloor over which the hardwood flooring will be installed must be able to withstand the heat generated by the radiant heating system. A concrete subfloor is the most common choice for radiant heat installations, but plywood can also be used. The subfloor should be level and free of cracks or other imperfections.
  4. Installation method: The most common installation method for hardwood flooring over radiant heat is floating, where the flooring is not attached to the subfloor but rather interlocks with itself to create a stable base. The flooring should not be glued down, as this can inhibit the movement of the wood and cause it to warp or buckle.

Benefits of Installing Hardwood Flooring over Radiant Heat

There are several benefits to installing hardwood flooring over radiant heat:

  1. Energy efficiency: Radiant heating is known for its energy efficiency, and hardwood flooring can help to further insulate the space, keeping it warmer for longer periods of time.
  2. Comfort: Hardwood flooring feels warm and comfortable underfoot, making it a popular choice for use with radiant heat.
  3. Aesthetics: Hardwood flooring is a timeless and elegant option that can add value and beauty to any home.

In conclusion, hardwood flooring can be installed over radiant heat, but it requires careful consideration of the type of hardwood, the moisture content, the subfloor, and the installation method. Consult with a professional flooring installer who has experience with radiant heat installations to ensure that your hardwood flooring is installed correctly and will perform well over time.

Here are some of the best hardwood flooring options for use over radiant heat:

  1. White Oak: White oak is a popular choice for use over radiant heat because it is dense and has a low moisture content, which makes it less prone to expansion and contraction due to changes in temperature and humidity. It is also more stable than red oak, which can be more prone to warping and cupping.
  2. Hickory: Hickory is a durable and hard-wearing hardwood that is a great choice for high-traffic areas. It is also a good option for use over radiant heat because it is less likely to shrink or expand due to temperature changes.
  3. Maple: Maple is another stable and durable hardwood that is a good choice for use over radiant heat. It is less likely to shrink or expand than other hardwoods, and its tight grain pattern gives it a smooth and consistent appearance.
  4. Brazilian Cherry: Brazilian cherry, also known as Jatoba, is a dense and hard-wearing hardwood that is resistant to scratches and dents. It is also a good choice for use over radiant heat because it is less prone to expansion and contraction due to changes in temperature and humidity.
  5. Bamboo: Bamboo is a sustainable and eco-friendly hardwood option that is also a good choice for use over radiant heat. It is less likely to shrink or expand than other hardwoods and is known for its durability and strength.

When choosing hardwood flooring for use over radiant heat, it is important to choose a product that is specifically designed for use in this type of installation. Look for products that have been tested and approved for radiant heat installations, and follow the manufacturer’s recommendations for acclimation, installation, and maintenance. Working with a professional flooring installer who has experience with radiant heat installations can also help to ensure that your hardwood flooring performs well and lasts for many years.
