John,
You are right. the old family farm that I bought 4 years ago had virtually no insulation. I have cut the propane bill from $1,550 to $650.00 last winter by adding insulation in the attic, basement and even pulling out some inside walls, insulating, rewiring and re-rocking. And consider where the price of propane has gone in 4 years, I have not figured it out, but have probably cut my volume of propane used by 70% or so.
And this fall I am putting in a high effeciency furnace and central air with all new ductwork. The furnace that is in the house was third handed, had been gotten rid of by 2 previous owners for burning too much propane.
Who knows I might be down to 400.00 or so this winter /forums/images/graemlins/smile.gif
