THE BEST SIDE OF LAND

FYI I live in a raised ranch, the stove is inside the basement, non-insulated block wall, the upstairs is about 1200sqft sorta open ground plan, basement region is about 500 -600 sqft. I capable of maintain the upstairs livingroom about 70deg when its about 10deg exterior, certainly the basement is much warmer.You'll be able to compute the losses t
