Can I install wood flooring over an in-floor radiant heat system?
Yes, as long as the subsystem is properly designed and constructed, and you are aware that you will experience more chance for shrinkage cracks between boards due to the surface heat. Depending on the type of radiant heat system selected, there are other factors to consider, such as chances for greater movement of boards due to increased spacing between fasteners, or longer construction time to allow gypcrete to cure before the flooring is installed if you select the gypcrete-and-screed system. We have found the system whereby the heat tubes are suspended beneath a conventional plywood subfloor to provide the best substrate for hardwood flooring, since it provides even support and adequate nailing. If you are considering wood flooring over radiant heat, please contact us during the planning process for the home so that we may discuss alternatives with you and provide specifications for the design and layout of the system.
