I have a modular rancher with 2100 sqft total basement and first floor. I had no heat in the basement when we moved in and i hate electric heat (that's my aux) so i put the stove in the corner in the basement as you come down the steps. My basement is also split by block wall with half being garage, so i can shut that door to push more air upstairs but then the bedrooms over the garage get cold quicker so i have been leaving the garage door open to heat the underside of that half of the house. In short if i leave the garage door shut i can have upstairs up to 75 easy on 35 deg day. But if i leave my garage door open the whole house stays a general 70-72 and seems to retain the heat longer. I've also stopped using my blower and that seems to help retain the heat after the fire is out.
