My other half is insisting we have engineered wood flooring over our underfloor heating in the lounge rather than my preferred choice of tiling. I will be using a steam cleaner that claims to reach temperatures of 140 degrees. Would we be better using an oiled finish or lacquered to protect the wood? I currently use the cleaner on a laminate floor with no underfloor heating and use tissue to mop up excess moisture and don't seem to have any visible problems.
