I would like to know before I buy a pellet stove if it will heat my upstairs very well. There will be a return vent about 5' from the stove and I believe it's the main one on this level. If I run my unit on fan only would it keep the upstairs warm? Also, do these stoves get so hor that they will run you out of the roon they are in? We will also be putting a TV above the stove will this be harmful to the TV? It will be mounted to the wall.
