Radiant heat can be used in a home depending on what it is. The manufacturer recommends installing "floating" engineered wood floors over radiant heated subflooring. However, the manufacturer's directions must be followed. To avoid drying out or distorting the wood planks, the subfloor must not exceed 85 degrees Celsius. Ensure that the manufacturer will guarantee their flooring if it is installed over a radiant heated subfloor by looking at their written warranty.
