Radiant heating systems are a great way to keep your home warm and cozy during cold months. They’re installed under your floors, delivering heat directly to the surface. But if you’re considering hardwood flooring with radiant heat, there are a few important things to understand before starting your project.
At Shanks Custom Hardwood, we often get questions about whether hardwood and radiant heat work well together. The answer is yes, with proper planning and material selection.
How Radiant Heating Systems Work
Radiant heating warms a room from the floor up. It comes in two main types: hydronic (hot water-based) and electric. Both systems are installed beneath the flooring and radiate heat upward. Unlike forced air systems, radiant heat doesn’t blow dust or allergens and provides consistent warmth.
Can Hardwood Be Installed Over Radiant Heat?
Yes, but not all hardwoods are equally suited for radiant heat. Wood expands and contracts based on changes in temperature and humidity. Radiant heat can make those changes more noticeable if the wrong type of wood is chosen.
Engineered hardwood is often the best option. It’s built in layers, making it more stable and less prone to warping compared to solid hardwood. If you’re set on solid hardwood, certain species like oak, cherry, or walnut perform better because they’re less sensitive to moisture changes.
Key Considerations Before Installation
- Wood Type and Thickness
Thinner boards transfer heat better. For solid hardwood, stick to boards under 3/4 inch thick. Engineered wood is more flexible in this regard. - Acclimation Time
Before installation, let the wood sit in your home for several days. This allows it to adjust to your home’s temperature and humidity, reducing the risk of warping once installed. - Installation Method
Floating floors or glue-down installations are often recommended over radiant heat systems. Nail-down installations may not work well with hydronic heating systems. - Temperature Control
Gradually increase the heat to avoid shocking the wood. Most manufacturers recommend that surface temperatures not exceed 80°F. Use programmable thermostats for better control. - Moisture Management
Keep your indoor humidity levels between 35% and 55% year-round. Using a humidifier during dry months can help protect your flooring.
Pros of Combining Hardwood and Radiant Heat
- Silent operation (no noisy vents)
- Even heat distribution
- Increased comfort during winter
- Better indoor air quality without blowing allergens
Downsides to Consider
- The initial cost of radiant systems can be high
- Not all hardwood types are suitable
- Installation requires expert handling to avoid damage
