A quick comment on warranty period and the AVERAGE home gas water heater
life.
The AVERAGE is exactly that: an average or mean calculation of the life for
all units shipped/sold. The real life span is affected by many things,
including the water quality/hardness (it consumes the anode quicker), the
temperature setting you select (hotter means it builds more internal
pressure and you get a shorter life) and the amount of hot water that you
use (more cycles of the burner mean a shorter life).
I am on my third gas HWH and purchased the house new in 1991. The first
heater lasted about 7 years and the second 6.5 years. I had a 7-year
warranty on the tank from Sears and they gave me a replacement free of
charge which has been in now for over 5 years. I believe that I will get a
longer life this time around since two of my children are no longer living
at home.
The gas water heater in my house was old when I bought the place in
1998...and it is still running fine. I think it is about twenty years
old - no leaks so far! And I had three teenagers living here for a
number of years...

The bottom line here is that the warranty period may be important depending
on your circumstances. It is basically a cheap insurance policy that covers
only the cost of a replacement heater. For me, that was important since I
do the installation myself, but for someone hiring a plumber, the material
cost could easily be less than the labor and associated miscellaneous
expenses (permits).
Good luck in whatever you choose.

Heating less water costs less, even with equally efficient heaters.
Sigh. Absolutely true and totally meaningless within the context of this
discussion.

It turns out Rick is right.
The size of the home water heater (e.g., 40 gallons, 50 gallons, etc.) is
nearly meaningless, as is the warranty period.
The only way the tank size plays any role in the selection process for
purely physical reasons. Why? Because both the EF and the FHR already take
into account the size of the holding tank so there is no need to even
bother to look at tank size (other than for purely physical reasons).
Likewise, the warranty is always less than the average lifetime of a home
water heater, which, at 13 years, is vastly greater than the 1-year labor
warrantees all the heaters I looked at (from Sears, Lowes, and Home Depot)
provided. (Note: The 12yr/9yr/6yr/etc. warranty figures often quoted by
Sears/Lowes/HomeDepot are for PARTS! Not labor).
Thanks everyone for enlightening me ... If I didn't know better, I'd buy
by
the size of the tank and the warranty but now I know they are meaningless
figures. The manufacturer WANTS you to look there but in reality, the
truthy lies in the FHV, EF, and cost/therm.
I didn't realize you guys knew so much about home water heaters ... but
I'm
glad you do. In only two days, I was able to take my knowledge level, with
your help, from absolutely nothing to being able make basic lifetime cost
comparisons given any two home heaters.
Thanks!
