Hi James,
I don't wish to argue and I certainly appreciate any help but I think
that's bad advice based on what I read.

For example, look he
http://www.candcheat.com/webapp/GetPage?pid=149

Where it says:
Although many consumers make water heater purchase decisions based only on
the size of the storage tank, the first-hour rating (FHR), provided on the
Energy Guide label, is actually more important. The FHR is a measure of how
much hot water the heater will deliver during a busy hour. The FHR is
required by law to appear on the unit's Energy Guide label. Therefore,
before you buy a water heater, estimate your household's peak-hour demand
and look for a unit with an FHR in that range. And beware that a larger
tank doesn't necessarily mean a higher FHR.

The point is that the volume of the water heater is, apparently,
meaningless from a standpoint of delivering enough hot water to meet our
needs. The volume is merely (apparently) a starting point - just like the
warranty is as meaningless as the volume.

So, it seems, based on my research, that to buy by volume and warranty are
exactly what the manufacturers want you to do to keep you as far away from
meaningful critera as possible.

What's really important, it seems, is the FHR and the EF. The only thing
I'm really confused about is whether two equal efficiency (to simplify the
argument) hot water heaters of two different sizes cost the same or
different amounts.

Do you know?
