The electric water heater was $179. A 60 Gallon gas heater was over
$400. So I figure I saved at least $220. As far as eBay goes, I
looked, I MIGHT have grabbed $50-$75 for the old one. The question
then is how long will it take me to run $220 of electricity through
the electric water heater? I'm guessing a while, and, a 60 Gallon
gas heater would have had an increased operating cost over the 40
gallon I have now. I suppose if you really wanted to crunch some
numbers you might come up with the most cost effective long-run
solution.

That would depend on your local cost structure. I would guess that in
some situations you would recover the investment cost quicker than you
think. In others it might not be worth it.

Next thought;
Would going from 40 to 60 and then dropping the temp from 150 to 125
really have increased my capacity that much? It would be 20 more
gallons at a lower temp? Again I suppose you would have to run some
numbers..

You also need to consider the recovery rate. Not all water heaters can
re-heat water at the same speed. A high recovery 40 may be enough if your
current model does not have a high recovery rate. I would also add that
having one 60 gallon heater will result in far less standby losses than two
40's.
