Honaracer2004 - Last year I burned a tick over 8 cord for the entire heating season. I'm heating approximately 4500sqft of an 1840's farmhouse plus DHW. The house is 40ft X 40ft with a full basement. The only heat that the basement gets in the winter is from the non-insulated hot-water pipes from the OWB. I guess when the pipes are consistently around 190/195 degrees something is going to get warm. I keep the living area of the house at 70/72 degrees 24/7 except my bedroom, that's at 65 degrees, if it's any warmer than that is too uncomfortable to sleep. Over the years I've done a lot of improvements to the house; the kitchen (a separate room) was completely stripped to the bones and rebuilt. It used to be drafty. It's amazing what insulation and caulking will do to keep the drafts away. My living room and dining room; again completely stripped to the bones and redone. Its now an open concept, one large room instead of the two. It's nearly 750sqft of living space.
Before my brother and I turned the second floor of the house into an apartment for him, it was never heated and poorly to non-existent in insulation. When we started that project the entire second floor was completely stripped back to the bones and heavily insulated. Now I have absolutely no heat loss through the second floor. Every time I remodeled a room, I made sure to spray-foam or caulk all areas where there was a potential for drafts, AND then before rebuilding everything was heavily insulated. It's made a world of difference in comfort while trying to read, listen to music or watch football. Roger
