water heater age

need to know the age of a Mor-FLO water heater

Model:SMIITW50S5CN8
serial:JM0796199

Also is there any place to find a list of water heater companys and the way to decipher the age/date of manufacture?

Re: water heater age

This is a sheet that I put together from information I obtained from this MB. I can't guarantee its accuracy. If anyone finds fault with any of the information on this sheet, please let me know.

According to my sheet, Mor-Flo is made by American, which would make your water heater 2007, week 96. Can't be.
Either my sheet is wrong (probably is) and Mor-Flo is not made by American, possibly Rheem. That would make it July of 1996.

Does anyone know who makes Mor-Flo?

Water Heater Manufacture Dates From Serial Numbers

American - The first two numbers are the year, and the second two numbers are the week.

AO Smith -Can be confusing; digits may be comprised of letters & numbers. May be one, two, or no letters.
If two letters first, next two numbers are year.
If one letter first, followed by two numbers and another letter, next two numbers are year.
If one letter first, next two numbers are year, providing no letter follows.
If two numbers first, this is year.

Bradford-White - They use a 20-year cycle. They skip the letters I, O, Q, R, U, V to make the full cycle.
1st Letter is the year. 2nd letter is the month.

A=84 B=85 C=86 D=87 E=88 F=89 G=90 H=91 J=92 K=93 L= 4 M=95
N=96 P=97 S=98 T=99 W=00 X=01 Y=02 Z=03 A=04 B=05 C=06 D=07

Lochinvar - Same as Bradford-White.

Rheem - The first two numbers are the month and the next two are the year.

State - 1st position indicates the month. 2nd and 3rd position indicates the year.
97 =1997, 98 =1998, 99 =1999, 00 =2000, 01 =2001, 02 =2002

Re: water heater age

If I were to guess at this one I would say it was made in July of 1996.

If you go here: http://www.fastwaterheater.com/waterheatermodels.asp
and scroll down to the "Bradford White" water heater, they are the only ones that use that code.

After speaking with the service department at American Water heaters (1-800 999-9515) They informed me that that is not a valid number.

If you get the correct number, call them and they will decode it for you.

Re: water heater age

American water heaters use the 1st two digits of the Serial number as the year. So something is wrong with the number.

Mor-Flo is manufactured by American. They must have changed their coding, because that does not match anything for American water heaters. I would say 1994 because the second digit is 4 and the ANSI date is 1991, which I always add 2-3 years to that.

It appears to be one shiny w/h though.

You should be safe stating 1994.
