Just curious what other's experience is with heating a home that has zero insulation. I have a 1929 brick home, and we have gotten our first real cold weather here this year, 21 degrees outside right now. If I have my insert absolutely cranking I can just barely maintain 70 degrees, but it has to be cranking constantly to do it. Overnight it dropped to about 65 in the house while I had the air turned down to get longer burns. I have not a scrap/tuft/wisp/piece of insulation anywhere in the house, and sometimes it feels like I'm heating a screened in porch! Even if I let the fire go out and just ran the furnace, it would be on darn near constantly in these temperatures. (I know cold is relative and some of you guys would think 20 degrees is warm ). Anyone else share my woes?
