Life expectancy of a Montgomery Ward water heater: this article describes how to read the data tag and de-code its numbers to determine the age of a Montgomery Ward water heater.
We show typical water heater data tag model and serial number formats and note where in that information the year or week or month and year are encoded.

Because we had trouble finding Montgomery Ward serial number decoding guides for the wide range of ages of manufacture of Wards water heaters in the books and de-coding charts provided by most publishers, we include a Wards water heater serial number decoding guide and de-coding examples here.

How to Decode Wards water heater serial numbers in format SNN 1280A12345
Standard de-coding for many Montgomery Ward water heaters whose serial number is printed as
depends on two pairs of digits in the serial number, digits 4&5 = the month of manufacture and digits 6&7 = the year of manufacture. So for my example the heater would have been made in December of 1980.
Mr. LeMarr has shared his free WATER HEATER AGE DETERMINATION CHART [PDF] that decodes both furnace age and water heater age for many brands.
How to De-code Older Montgomery Ward water heater serial numbers in format Ser# TE22780
Query: 01/24/2014: G M Wagner said: Montgomery Ward Electric Water Heater-Model 94-SHT-2861A, Serial # TE22780 . Would you please tell me how old it is. Remodeling the basement and finally putting in a new one. thank you.
Reply: best guess: 1980
For decoding the age of a Montgomery Ward water heater, your Montgomery Ward electric water heater serial number is of an older format TE22780 that does not match the water heater age decoding formats I give just below. Providing you're giving me the whole n umber, and pending further research most-likely the year in which the water heater was manufactured is coded in the last two digits of your example - meaning this heater was made in 1980.

Query: (Jan 11, 2012) Doug said: My Montgomery Ward Signature 700 water heater is not working. Any idea how long it's been in my house? SER# is 1170 3310 SN
Reply: Doug, MM YY NNNN - 11 70 3310 means it looks as if your Wards Signature 700 water heater was built in November 1970. We can't say when it would have been put in the home, but if it is the original water heater then it would have been installed most often not long after its production, perhaps a year or two.

For decoding the age of a Montgomery Ward water heater,
your Montgomery Ward electric water heater serial number is of an older format TE22780 that does not match the water heater age decoding formats I give below. Providing you're giving me the whole n umber, and pending further research I'm guessing the year is coded in the last two digits and = 1980.
Standard de-coding for many Montgomery Ward water heaters whose serial number is printed as SNN 1280A12345 depends on two pairs of digits in the serial number, digits 4&5 = the month of manufacture and digits 6&7 = the year of manufacture. So for my example the heater would have been made in December of 1980.
Wards water heaters have also been marketed under Wards Signature brand and the Reliance brand and were produced by State water heaters (if not other manufacturers).
For State water heaters manufactured for Montgomery Ward, an 8-character serial number was used (one more digit than yours) and are decoded as follows, using Carson Dunlop Associates example of
where the "B" position is an alphabetic code for month of manufacture (A-M omitting use of I, where A = January) followed by two numeric digits of year - B9912345 would decode as February 1999.
Use the CONTACT link at page top or bottom of our website pages and send me some sharp photos of your water heater and closeups of its labeling and I'll research this further.

Spare Parts for Rheem, Paloma, Wards water heaters
You will need your equipment brand, model number and serial number to be sure that proper parts are being ordered. Look for the data tag on the equipment. On furnaces and some other HVAC equipment the data tag may be inside of an access panel or cover. [Turning off power for safety may be necessary before removing the access cover on some equipment.]
[Online and telephone support are readily available. Good luck trying to find a brick-and-mortar address or email - Ed.]
Finding the Data Tag on an Older Wards Signature 500 Water Heater

Hi, we need an age of our electric water heater. I've attached several photos, we could not find a serial number plate. Thanks for your help. We are trying to win a "Oldest water heater in use" contest, to win a new water heater! Thanks, D.P.

We have an old Montgomery Ward Signature 500 Series, electric water heater. We cannot find a serial number. Would a picture help or is there another way to determine the age of the unit.
Good looking water heater. If you have access to all sides of the heater exterior and still don't see an actual data tag, I would pull the access cover on the front - chances are there will be a data tag inside on the cover or on the heater itself. If you do that, send me images of what you see.
I'll post your photos to see if other readers can offer further help, but best bet is to inspect all around the heater sides and top and behind the removable front service panel for a data tag.
The Signature water heater line sold generally under the Wards brand was made by several manufacturers (listed in the article above) and has been sold in North America since, by my estimate, 1948.
Here are several approaches to finding the age of this or any other water heater / cylinder / geyser
Your Signature 500 electric water heater (or geyser or cylinder depending on where you live) looks like a much newer installation. I see light colored wood 2x studs (recent construction) and shiny copper electrical wiring at the ground connection at the heater top. Also I see the use of modern red PEX tubing used for the temperature/pressure relief valve discharge tube.
Certainly the heater could be older than its present wiring and plumbing, but if those are any guide, this is not a very old unit.
Depending on where you live we could get a more accurate estimation of the year of installation of the water heater plumbing as presently shown even before finding the heater's data tag (which I am betting is there somewhere). PEX surged in popluarity in the U.S. beginning around 2000.
For example, in the United States, California, one of the last adopters, did not approve the use of PEX (cross-linked polyethylene tubing) for household plumbing until 2007 (on a case by case basis) and not until 2009 for all homes. More about PEX plumbing pipes used for building water supply and hot water heating applications can be read at PEX PIPING INFORMATION.
