Disagree Steve......

As another poster said, hot water does not need to be heated. Hooking 2
heaters in series will not double capacity, it will however double your
fuel bill and cut the life of both water heaters in half.
No disrespect intended, but it just doesn't work that way.

Matt

Yes it does work that way...

Cold water flows in to the bottom of the first tank pushing the hot
water out of the first tank in to the bottom of the second tank which
pushes that hot water out the top of the second tank on to the shower.
So you will fill the first tank from the bottom to top giving you 40
gals of hot water then you fill the second tank from top to bottom
giving you a second 40 galls of water. Fuel usage increase will only
be from the reheating of the addtional water it wasnt possible to use
before and the standing loss of the additional tank which isnt that
great now days since tanks are hightly insulated. This setup is very
common in high end homes with the huge garden tubs.

And yes hot water does need to be heated. 60 degree water is "hot"
compared to 32 degree water but that doesnt mean i want to take a
shower in it. Thats a stupid semantics game and I would think most
here were past the age of twelve when those things were funny.
