My woodburning stove reaches high temperatures but my hallway and bedrooms are still a little chilly. I have a blower on the stove and turn the ceiling fan on in the dining room bit the heat just doesn't get down the hall and to the bedrooms. I don't remember the exact sq footage of the house; just moved here a few months ago but I believe it's over 1200. As for the controls on the stove; I know you open both when first starting the fire but when do you close them and can you keep the secondary one open which is located in the center of the unit?
