Installing hardwood over radiant heat systems is achievable, but it requires careful coordination to prevent the wood from drying out and separating. The heat from the subfloor can cause wood to lose moisture quickly, leading to gapping or even board splitting. Engineered hardwood is typically the superior choice for these applications because its layered construction is less prone to shifting under thermal stress. If using solid wood, you must ensure it is a species that is specifically warrantied for radiant heat use by the manufacturer. Successful installation also depends on the radiant heat controls. The surface temperature of the wood should typically not exceed 85 degrees Fahrenheit. We advise installing the wood only after the radiant system has been commissioned and tested to ensure it functions correctly. It is also vital to monitor the indoor relative humidity, keeping it within the 30-50% range as per NWFA standards, to balance the floor's moisture content throughout the heating season. Consult your flooring manufacturer for their specific requirements regarding subfloor temperature limits and installation techniques.
