Scrooge McDuck once said "A dollar saved is a dollar made" and I applied that to my latest investment.
Cavity Wall Insulation
Now thats something that doesnt apply to many of you because you got to own your house and it has to be built in a certain way, but it involves insulating the outer walls of your house in a quick invisible way by injecting insulation material between the outer and inner walls of the house.
Given the particulars of my house, bear with me:
Cost was 550 bucks. A onetime investment, you never have to redo it.
For my house, expected savings will be 1/3 of central hearing cost.
My central heating cost right now is about 1,200 bucks a year or 100 bucks a month.
Take off 1/3 and I save 400 bucks a year or 33 bucks a month.
That means that in 1.5 year the insulation paid for itself.
I plan to live in this house for at least 30 years more, unless life intervenes.
Know what that is? An investment of 550 bucks yielding me a sum of 12,000 bucks (in todays money). Thats 21.8x the initial investment, that rivals the results of an excellent investment firm. And mind you, it grows with inflation and increase in the cost of energy. If I sell the house in the mean time, its worth more because its got that insulation in effect.
Those are 550 bucks damn well spent

while there's a lot of heat loss in many older homes because of poor insulation in the walls, one of the largest sources of thermal transfer is through air infiltration, a few tubes of caulk could help you save a lot more money, improving your windows to an insulated unit will also greatly benefit an older home

You are right, my windows have already been done, and it did save a lot of energy to be sure!
Getting the windows and frames done was a 10K job but this is something you can do for just 600 bucks that makes as big a difference.

during college me and some friends lived in a big old house (3 bed, 2 large living rooms). the place was insulated like this and the widows were all double pane. my roommate kept it below 70 and in the dead of louisiana summer we paid a little over 100 for the total electric bill. this is one of the few places that i even recommend using credit if you have to to pay for something as long as the saving go to paying off the debt.
