Can you put heated flooring under wood flooring or plank

It somewhat defeats the purpose since the wood acts as an insulator. While temperature does not harm the wood, it does affect its moisture content. As the temperature goes up, the moisture content generally goes down. Heating the wood too much will cause it to shrink and gaps will occur between the boards. Once the temperature is lowered, the moisture returns and the gaps close up. Laminate floors are less subject to shrinking due to the construction features. Here are three rules to follow:

1. Low Temperature - Keep the subfloor temperature as low as possible

2. Even Heat - Spread the heat in the subfloor as evenly as possible.

3. Acclimate - Make sure the subfloor and the wood flooring are acclimated to the finished room before the wood is installed. The subfloor or slab must be dry.
