Is it safe to install hardwood flooring over a radiant heating system?
Yes, hardwood flooring can be installed over a radiant heating system, but it is recommended that the width of the flooring installed not be more than 4. It is also recommended that a rift sawn or quartersawn flooring be used because of its superior dimensional stability. The subfloor the flooring will cover must be thoroughly dry, this can be accomplished by running the heating system for 1 to 2 weeks prior to installation. This will prevent moisture from entering the flooring from the subfloor while the heating system is running. You should make sure that your flooring is thoroughly acclimated prior to installation. As with any hardwood installation, floor performance will be dependent on the severity of fluctuations in relative humidity in the home throughout the year.
