If choosing engineered.
Best engineered wood flooring for radiant heat.
Engineered wood flooring works better for radiant heating than under solid hardwood.
For examples look at our northern lights collection.
The best type of wood flooring construction to use would be a floating engineered floor.
Engineered wood flooring is in general more dimensionally stable than solid wood flooring.
But if you do wish to put radiant heating under solid hardwood use quarter sawn wood flooring instead of plain sawn wood flooring.
Quartersawn wood flooring is always more stable under conditions of extreme moisture or heat and is always a good choice over radiant heat especially when going with flooring wider than 4 inches.
Engineered flooring works well over radiant heat because its unique plywood construction creates greater stability as each wood layer is positioned perpendicular to the other thereby resisting movement from environmental fluctuations depending on the selection can be nailed glued or floated over the subflooring.

Guide the homeowner in selecting a hardwood floor that is appropriate for their scenario.
The inherent dimensional stability of engineered hardwood floors makes it a great choice for radiant heat systems.
Certain solid hardwood floors are appropriate as well.
However not all engineered wood flooring is recommended or appropriate for use over radiant heating systems.
Plainsawn wood will move more than quartersawn especially when it is over 4 inches wide.
The heating element should be embedded within a sleeper system subfloor under a traditional subfloor or embedded within concrete.
Engineered flooring with a less stable wear layer species such as hickory beech and maple are not normally best suited over radiant heat.
