One of my personal reasons we attacked the kitchen was that it was freezing cold in the winter. I dreaded walking in to the kitchen in early morning before going to work knowing that it was going to be a chilly 58 - 60 degrees even though the thermostat had been set at 64. So in went the Icynene insulation, a bit more than fiberglass, but I'd never forgive myself if I did not seal that room as tight as I could.
Well today was a big day for us. The heating bill arrived for December and I liked what I saw.
Dec 2008 Therms: 259
Dec 2007 Therms: 340
difference: 81 Therms or 23% less then last year.
My wife may not admit this, I've even had the heat a little higher this year to keep the baby Beech-nut warmer. Everyone gets a break on their first winter, then it's back to the program on the thermostat.
