Nifty Griff.

We just finished the insulation phase of our master plan and now have 8" of dense packed blown cellulose in every wall of the old house. Plus all new insulated windows. The addition has 5.5" of cellulose and the kitchen, since it is mostly windows has 5.5 inches of rigid foam board. R-30.

No heat yet, a comfy 68 inside. We are angling to put in a solar hot water maker for domestic HW this year, as a shake-down cruise for a larger array to heat. We use about 350-400 gal of oil per year to make hot water. At $4.00/gal that's about $1400 to $1600/ year. The solar system installed (by me of course) would run about $3800, so that's about a three year payback. Unless of course oil prices plummet to .76 a gallon, then I'm fucked.
