This is all very good but can you trust the figures given by the
manufacturers as these are often derived by engineer calculations and
marketing guru's and are manipulated to suit their agenda.
Hi Only Just,
I *think* you *can* trust these numbers (FHR & ER) ... but I'm just going
by the written facts. You have the experience I don't have.
The facts are that there are *independent* labs paid to *verify* that these
FHR and ER numbers are accurate, for example, OSHA recognizes ITSNA whose
numbers I quoted throughout the latter half of this thread.

Gama says, as of December 12, 2007, "Intertek Testing Services of Cortland,
New York (
http://www.intertek.com/) has been retained as the program
administrator and *independent* testing laboratory responsible for
conducting efficiency *verification* tests on water heaters" (emphasis
mine).
If Intertek is truly "independent", and if they do randomly select units as
their product literature says, then I think you *can* trust these numbers.
