The total cost after our PG&E (local energy company) rebate should be just over 900 dollars. If the savings are up to what we expect, I actually did this long involved calculation using R-values, previous BTU’s used (we have 3 years of gas/electric bills saved up), etc, we should have it paid back in two winters, three at most. That’s assuming of course the cost of natural gas doesn’t go up (that’s our heating source), which we know it will (then the pay back will be quicker of course!)

I’m trying to do things that are good investments and would pay back in savings in a maximum of 7 years. We did our light bulbs over a year ago (over a year period), changing from incandescent to compact florescents. That paid for itself already, or is about there this year.

Solar energy right now would take over 10 years to recoup the cost, so we are waiting for those prices to come down (soon!) and the price of electricity to go up (already started!)

etc…

Out of curiosity, Trey, how much did it cost in total? And do you think it’ll end up earning its cost back through heating bill savings?

(oh shucks, I shoudl read more carefully! You DID tell us how much it costed!)
