What keeps you from just turning it on & trying it ?
My return is at the top of the basement stairs - stove is at the bottom. Early this season, I tried running on recirculate - just screwed up my airflow & made my basement hot. My air handler draws 10 amps ~1200W @ 20c/KW/h
!!!! so it would cost me ~ $6 a day to run it alone - not worth it even if it would have worked.
of course your mileage may vary
