Ok so I have a 1700 sqft raised ranch, the l/l has a fireplace in the corner of the room. Now I wanted to install a Harman pellet stove insert, but am curious to know if the heat would make it to the top floor (dining/kitchen/3 bedrooms). The l/l has a door that must be opened in order to get into the room, not your typical ranch opening to stairs etc. Am I just better off with a freestanding unit on the top floor or would an insert do the job with some fans to circulate the heat? Thanks in advance to all who reply.
