After the storm windows adding blown-in insulation to the attic is the next best investment. Two years ago I invested about $2900.00 in boosting the attic insulation from R 20 to R 50.
The house is all-electric...and since then almost every bill has been lower or at worse equal to the final year before insulation despite utility rate hikes.
Insulated against inflation—LOL.
I’d love to be able to do that but we just don’t have the extra $$$ to do it. That’s why I need to win the lottery. LOL!
But first, I’d have to play it and my luck’s so lousy, I don’t bother. :-)
The original part of the house is heated by a large gas heater and the section added on is electric heat. The whole house is a mish-mash, but it’s home.
