My house is very small 800 sq ft on first floor, basement is only being heated on one half of basement. The other side is other rooms with very little heat. I am hoping to heat the kitchen, living room (open concept) which is directly above stove in basement. Floor register between kitchen and living room and I leave the basement door open. I also have a cold air return down the hallway which goes downstairs into one of the unheated rooms. Any thoughts??? Oh, I have the Big E which is supposed to heat 2200 sq ft. Thanks
