In most houses the only place to do this is on a first floor where joist bays are open to the space below.
Radiant heating on wooden floor in crawl space.
Under tile slate and wood space the plates every 8 for more specific info on radiant heat with wood floors see this link.
In this situation hydronic radiant heat water circulating through pipes would be easier to install than electric mat radiant heat.
But these methods i have described here will work for wood floors over these hydronic heating systems.
Just keep in mind that running the plates continuously under any floor serves to enhance the overall performance of the system.
Installing a hardwood floor directly over a crawlspace exposes the wood to moisture from the ground and from the air in the crawlspace.
