At the end of a typical shower there is warm water in the tub about 4
inches deep, 15 to 18 inches wide and about 48 inches long. These are
probably a bit overestimated; but to continue ............. that's 0.3
x 1.5 x 4 cu feet of water = 1.8 lets say 2 cubic feet of water?

Never mind the energy issues -- you need to find out what's clogging your
drain!!

If you want to get that anal about extracting 8 cents of heat from
shower waste water, they do have heat recovery devices you could
install in the drain line. * It's basicly a heat exchanger that runs
the exiting waste water past the incoming cold water that is going to
your water heater. * I doubt it's practical, worth the cost/trouble,
etc but at least you don't have to stand in 4 inchs of water taking a
shower.

Think you guys need to get a life if this is what you do for
excitment . lighten up pay your heating and stop being so cheap.

Frugal, not cheap, there's a difference. A good engineer keeps
material, energy, labor costs low, either for himself or the company
where he works. A fool and his money soon part.

Remember when touch-tone telephone was $1.50 extra per month? Well, I
make few calls per month and used rotary dial for 40 years...

$1.50 x 12 x 40 = $720

Approximating interest on 720 gives

$1360 saved for using rotary dial telephone. Not exactly a large
amount, but not musch missed with rotary dial. Today, I still have a
rotary dial phone, but touch tone is now "included free."
