Radiant Heat Sub Floor

[Ringo311]

Can anyone give me advice or suggest a hot water radiant heat system for a 200SF addition that sits on a concrete slab, but also has a 3/4" plywood floor countersank into it? I installed a hardwood floor in the room and heated with a wood stove, but would like to change to radiant heat under the hardwood floor.

Yes, you will spend a whole lot to make that happen.
If money is not an issue then you can have the slab horizontally drilled to accept the piping for radiant heat.

My concern is what contractor would counter sink plywood into crete just to put a hardwood floor down ? Its much easier to plan accordingly and fur out the floor.
