Well, I've undertaken a project to capture more heat this winter and, therefore, have a more comfortable home. I have added an extra layer of insulation in the attic (unfaced R30 running perpendicular to the floor joists). I am about to insulate the Rim Joists in my unfinished basement. There is, currently, some fiberglass insulation jammed in some, but not all, of the Rim Joists. Some are actually open. I plan to remove the fiberglass insulation where it exists, caulk all of the joints, and install 2" styrofoam insulation. I also "invested" in a Nest thermostat. I am trying an experiment where I run my HVAC fan for 15 minutes each hour to see if I can even out the heat in the house (at least on the first floor). My windows and doors are tight in the house. I have done some work to seal a few small "holes" in the wall associated with pipes, etc. by putting some spray foam in. I'll try to remember to update folks on what I've found. I will say that it will be a bit hard to tell because my wood pile (mostly oak and maple) is now 2 years old. So, I should have much better wood to burn this year (last year my wood sat just south of 20% M.C.).
