Used as is, a conventional wood stove will not work for this, it relies on
an external chimney to create the draw which drives the system, and this
needs to happen before routing through the bench, so yes she would need to
build some kind of heat riser.

NOTE: in theory, a really tall chimney after the bench could work, but it
would need to be way to tall to be practical if any significant amount of
heat is dumped into the bench, which is the whole point.
