Thanks to advancements in technology over the last decade, it is now possible to safely install radiant heat beneath hardwood floors without damaging the wood. One of the main benefits of radiant heat is that it provides even heat distribution throughout your home, enhancing both comfort and value.
While radiant heat and hardwood floors offer numerous advantages, there are a few simple guidelines to follow to ensure a smooth HVAC and flooring experience.
Steps to Follow:
-
- Always follow the installation, maintenance, and warranty guidelines provided by the wood flooring manufacturer. For example, some manufacturers do not cover products installed over radiant heat under warranty, while others may honor warranties if their specific installation and maintenance instructions are followed. Engineered flooring is generally more likely to be covered under a warranty for use with radiant heat.
-
- Ensure you include the proper system controls when installing your radiant heating system. It is highly recommended to install a thermostat outside your home and at the outflow points of your boiler or water heater. When set correctly, these thermostats will help prevent sudden and large temperature fluctuations, which can “shock” the hardwood floor. The temperature of the floor itself should never exceed 80°F. Significant temperature swings can cause issues such as cracking, face-checking, bowing, and gaping.
-
- If you’re installing new hardwood flooring over a new concrete or plywood subfloor, ensure you or your contractor check the moisture content of the subfloor in comparison to your wood flooring. The difference should not exceed 2-3%. For concrete slabs, it can take up to two months for the concrete to fully “cure” and stabilize. Once cured, run the heating system for 5-6 days before installing the hardwood floors to eliminate any residual moisture. For plywood subfloors, 2-3 days are sufficient. Always check that the subfloor temperature does not exceed 80°F before installation. After adjusting the heating system to the manufacturer’s recommended settings, you can proceed with installing your hardwood flooring.
-
- To maintain the longevity and stability of your floors, keep the relative humidity in your home between 35-55%. This range ensures comfort in your living space while preventing damage to your wood floors, as excessive moisture or extremely dry conditions can cause severe damage. A central humidifier/dehumidifier system can help control the humidity levels.
By following these simple guidelines, you can ensure a positive and lasting experience with both your hardwood flooring and radiant heating system. For expert advice and assistance with your next radiant heat flooring project, reach out to the team at Unique Wood Floors.
