not sure what to do...I will try and describe this... On my lower level, off of my kitchen I have a mud room(entrance area), a room that is unfinished, (also right above this room is another unfinished room) and my basement door ( basement is very drafty). My pellet stove is in my dining room. Would you leave the doors open to the basement and to the unfinished room so warm air gets into these areas or would that be wasting my heat. My thinking is If I opened the doors and try to warm these areas, that the rest of my house my stay warmer. Now my stove is not the greatest so I don't know. I probably am going to have to try this but but just looking for some input if anyone else is in the same situation as I am. Basement door is the blue area.
