Superstor Water Heater Serial Number

Marathon water heater age decoding from serial number. On Marathon water heaters the age is encoded as the first four digits of the serial number. Contact Information for Marathon water heaters. Marathon water heaters are currently (2015) a Rheem product. First, locate the manufacturers label with the serial number on the side of your unit. This sticker is usually around any warning labels and the energy guide. Check to see if the installation date is noted on the sticker. If not, then write down your serial number as it usually indicates the year and month of manufacture of the water heater.

my 7 year old superstor indirect hot water tank is leaking
I am wondering is it is normal that I have to replace my 7 year ols superstor SS-30. The cold water intake nipple that is stainless steel and welded into the tank has water weeping through the unused threads. I believe this has happended because the nipple is stainless and the cold water connection is copper pipe. The 2 disimilar metals cause corosan and leaking. Also when no one is using hot water this cold input pipe get hots and when someone uses hot water the pipe is cold, this constant heat and cold expansion and contraction of 2 disimilar metals has a affect. Can some one recomend a reliable indirect hot water tank?
Thanks for your help.

If the problem is simply water seeping through the threaded connection , you might think about having someone disconnect the connection and re seal the threads. I'm not a huge fan of dielectric unions but that would stop or atleast slow the corrosion between the copper and SS, if indeed there is evidence of electrolisis. As far as hot water bleeding into the cold water inlet, a heat sink would stop some of the transfer.
WARNING
Never use dielectric unions or galvanized steel fittings on any domestic
water connections. Use only copper or brass fittings. Teflon thread
sealant must be used on all connections.

Hey Chuck thanks for the correction
any idea why that is?? The disclaimer appears to pertain to the Ultra, was it also part of the SS 30 spec's as well?? been looking for manual for SS 30 cant bring one up, only thing available is Ultra, just curious. Thanks

When I tried to take the connection apart the nipple broke off where the brass tee ends and the stainless steel nipple begins. When you look at the break point you can see the thickness of the nipple on the sides and bottom is 1/8' thick but the top section of the nipple (at 12 O'clock) is less that 1/16' thick. This is what I believe is the electrolisis problem.
I tried to re-tread the nipple but there is not enough room with my pipe tread tool is to large and there is not enough nipple left.
Here is a temp fix for this to keep your wife from killing you in your sleep because she has no hot water in the whole house for the weekend because 'YOU' broke the water heater.
I brought the water supply down and 90 degree elbowed with a 2' long brass 3/4'nipple up to the broken nipple, then went to my favorite AUTO PARTS STORE with a 3/4' nipple and said 'you have any heater hose that this 3/4' pipe will fit in?' They did and I bought a piece. Went home slid the heater hose on the broken nipple and pushed the cold water supply nipple into the other end of the heater hose and put 6 hose clamps on it, and turned on the water ! No leaking at all. I told the wife OK you have hot water now but we should start thinking about buying a new hot water heater.
I also added a strap around the tank and the cold water supply line because I was worried with it getting hot and cold it might blow off so the strap will keep that from happening.
I guess from the posts so far that this is not a common problem. I did notice that alot of water heaters have a warranty of 5 years. I noticed AMTROL has a forged brass plate where you connect the water, this looks like a better design, does anyone have any knowledge of this unit?
The SS30 is the
'older' version of the Ultra. I am not sure of the date on the switch of the name.
Chuck
Nice save in a pinch Don
Sounds as though electrolysis is a possibility. AS far as Indirects go I've had pretty good succes with the Tank in a Tank design such as Tiangle tube or it's sister Weil Mclain.Dielectric's are permitted by these Manufacturer's. Keep in mind electrolysis may not be the problem water content or possibly a grounding issue are other factors as well.
Don,
Check with the warranty department at HTP tomorrow
1-508-763-8071 ext 150
Have the model and serial number ready.
You may still have some warranty left on the tank
Chuck
Don
I am a Plumbing Contrator and use Super-stor tanks ALL THE TIME.
We have very little problems with these and would use this tank over a Amtrol every time.
I would look at the inlet preasure to see if you have excesive preasure which would wear down the thickness of the metal. Possible a poor joint from installation could also be the culprit.
I can't remember the last leaking Super-Stor we had.
Scott
Hey Scott,
I remember the last leaker...I forgot to press a connection. The person servicing the oil burner found it about 4 months after install.
Don, I'm with Scott on this one. I've only seen one tank returned in the 15 or so years the Super Stor has been around. Follow Chucks advice and call.Nice fix in the jam too! Chris

Hi Scott,
I am wondering how you hook up the superstor. I have copper water line into brass tee's or elbows onto the stainless steel nipples with pipe dope. I noticed in the ultra superstor installation manual it says teflon must be used on all connections but in the same book for the cold water inlet it say's both tape and pipe dope must be used (page#9). This sounds very strange to me, I think this is the first time I have read somthing like that.
Also I was talking with a heating supply guy and he said when superstor first came out they had a leaking problem, but then they corrected the problem, do you know anything about this?
Someting to check
I had a problem years ago with a Polaris. Had several leakers and was told to check the tank against ground. I drove a stake into the ground outside and ran a wire from it inside to the tank. Then I checked to see if there were any millivolt difference between them. There was. I then found the electrical panel was grounded to a water pipe instead of an electrical stake. The city changed the incoming water lines to plastic, thus losing it's grounding capabilities. This was causing the leaks because any stray voltage in the house was trying to ground out through the tank, causing electrilysis and leaks. Whew! That one really made my brain hurt figuring it out. Something to check just to make sure. WW

Yes
Years ago Super-Stor was made with a thru hull fitting that would spin of over tightened. Once the company switched to welding that problem was solved. I can't remember that last leaker we had ( except for poor installation ..Chris ).
I good joint is a good joint. Pipe dope, teflon, pipe dope and teflon. Its all good, as long as it dos'nt leak. I can not imagine a thread compound effecting electrolosise.
Call HTP. Good product, good company.

you asked about an alternative DHW tank
and the best warrantee in the industry is offered by Viessmann . The performance is none to shabby either. Ask Paul Polletts about his experiences.
Ok, Here is a update on this problem. I called superstor with the serial# on the tank. They said it is lifetime warranty but I have to hire a plumber to do the uninstall and reinstall and the plumber will deal with superstor.
However, my wife does not want another superstor after all the problems with the first one. I went to a couple of plumbing supplies and found that most indirects are stainless steel. Also talking to one guy and talking about the constant leaking at the cold water input he said 'WICK-IT' . I said what is 'WICK-IT' . He explained that you put pipe dope on the male thread and then wrap a cotton string in the thread . then add more dope and make the connection. when the joint starts to leak the cotton string will swell and stop the leak. It is to late for me since the nipple broke off , but I thought I would share this with you guys.
I found a indirect water heater tank that looks good to me. It is 'Vaughn top performer' The connecting nipples are brass and the tank is stone lined. The nipples look like they are replacable. The price I got for the 35 gal tank is $660.00 . Does anyone have info on this hot water tank?
Check out Ken's article ' Dope'
It talks about wicking and several other sealents as well as applications and practices.
aargh
'However, my wife does not want another superstor after all the problems with the first one.'
With all due respect to everyone out there that says things like the above quote, AAAAAAAAAA! Not to poke fun at your wife, however you just had a few experienced proffesionals tell you that these are good units.
You also know that HTP will warranty the tank.
In addition you recieved some great info on checking your grounding situation, and to check the chlorine levels. It does not matter whose equipment you use, if the last two items are problems (grounding, and chlorine levels) the same thing may happen again no matter what brand you buy.

I forgot to mention I did look for a grounding problem and my electrical box is connected to a ground rod not the water line.
I am not not going to check the clorine level because I know that my water company adds clorine to the water and that are not going to change it for me.
From the info posted in this thread clorine and stainless don't work well together and also when you put 2 disimilar metals like stainless steel to copper you get corrosian.
looking at the vaughn tank it has brass nipples so brass to copper are a good match and stone lined tank is not affected by clorine levels so I think this vaughn tank fits my situation best.
Vaughn water heater
Don check the Vaughn sizing chart to make sure 35 gallons is enough for your water usage, you may want to increase to a larger size. The Vaughn tank is a good quality choice. Good Luck.
> Don check the Vaughn sizing chart to make sure 35

The 30 gal superstor was fine for my needs so the 35 gal vaughn should be more than enough. I heard that when the vaughn first came out the coil was wraped to tight and it had trouble making enough hot water but since then they made a improvment and it makes the correct amount of hot water.
Thanks
Don
Out of the frying pan
and .....
Don, the Super-Stor is the better product. You did'nt have problems with the super-stor, you had problems with the install. You had a poor joint not a poor tank. The joint leaked long enough to cause corrosion. We install these tanks all the time and have NO corrosion between the two metals. Viessmann tanks, arguable the best on the market, are a stainless steel tank !!
Vaughn moved the tightly wound coil from the bottom to the top ??
You don't have a product problem, you have an install problem.
My two cents worth.

Super-stor
We've installed hundreds of ultra tanks. We have never had a leaker. Never! We previously installed a blue tank that looked like a bomb. It was. Changed a dozen bad bombs, got no help from scamtrol. Will never get scammed again by them. Heat Transfer has always been great with any questions or problems. Just never had any with their ultra tank. I think you jumped to a wrong conclusion. Sorry.

Water Heater Age Decoding Charts & Tables: Six ways to find out how old your water heater actually is

1. Specific Water Heater Age Decoding Guides by Brand

Specific Water Heater Age Decoding Guides by Brand are given below in an alphabetical list starting at at WATER HEATER DECODING by BRAND - list of water heater brand names, manuals, contact information, found below in this article.

The data tags (containing the water heater's age) for this heater are hidden by its insulating blanket. Readers who need to determine the age of air conditioning and heat pump equipment should see A/C DATA TAGS.

How can we determine the age of a residential water heater? By looking at and decoding data on the water heater's label.

Nearly all modern water heaters, electric, oil fired, or gas fired, include data tags and stickers that indicate the year and month of manufacture of the water heater.

That doesn't tell you exactly when a water heater was installed in a particular building but it does indicate the age of the water heater itself.

However some manufacturers encode the year and month of manufacture of their water heater in the product's serial number so that the water heater age is not immediately obvious.

Carson Dunlop Associates Associates provide a most-comprehensive Technical Reference Guide to heating and cooling equipment manufacturers that includes water heater manufacturers.

For an encyclopedic reference including manufacturers, history, contact information, and serial number decoding we recommend this book.

Scott points out that

On occasion there is a yellow 'Energy' label on the unit and at the bottom (sometimes middle) will tell you what ANSI Spec it was built to or it may give you an estimated cost on a particular year. If it reads ANSI Spec 1994 that it would have to be 94 or newer typically these specs come out every 2-3 years.

6. How to Decode Non-Standard, Unknown Water Heater Serial Numbers & Data Tags to Guess Water Heater Age

Approaches to finding the age of any water heater / cylinder / geyser are given here. If your water heater brand or trader name doesn't appear in the list at WATER HEATER DECODING by BRAND you can use this general data tag decoding guide.

[Click to enlarge any image]

Find the data tag (as I've discussed above) that will allow us to decode the date of manufacture of the heater.
Look for reasonable apparent year ecodings in the equipment serial number in format MM YY
The unit's serial number, MM02-2147713-260 identifies the model and its date of manufacture. The '02' following MM indicates that this unit (in our laboratory) was manufactured in 2002 and the -2 following the MM02- decodes to February.
In a second water geyser age (cylinder age, water heater age) example, Rheem water heaters provide first the month MM and then the year in the first four digits of the water heater's serial number.
The label shown here includes 0884 at the beginning of the serial number - August 1984.
General approach to decoding unfamiliar water heater serial numbers to get water heater date of manufacture
Typically the manufacturer used
a two digit month and two digit year,
OR
1 digit month that used alphabetic characters
OR
2 digit week (1-52) and 2 digit year
WITH sometimes a plant ID code in the serial number, typically a letter, separating the numeric or other age and serial number digits.
So if we have no other data, we look for a pattern that can decode to a reasonable year using those schemas.
Using Rheem water heaters as an example many, not all, water heaters made by Rheem were sold under other brand names such as Montgomery Ward.
Modern Rheem water heaters use a 10 digit code:
MMYYX12345 where X is the plant code and 12345 a consecutive unique ID and of course MM YY are month and year.

Find the installation and service manual for this particular water heater.
Often the installation guide is stuck behind a pipe or overhead nearby. The manual may include a purchase of sale receipt, handwritten notes on installation date, or even lacking these, it will have a publication date that gives the earliest-likely manufacturing age of this specific heater.
Note the age of the building where the heater (geyser, cylinder) is installed.
Note the age of components used to install the heater such as its wiring and plumbing materials
Contextual clues of water heater age: Note the age and location of the building. That will give us some context. Also note the age of remodeling or building changes.
Here is an example commentary about water heater age we provided to a reader:
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.
Look around the heater for a water heater service tag, perhaps stuck in a floor joist or on a wall top nearby - that can give an idea when the heater was installed or may give that precise date.

Water Heater Age Decoding, Manufacturers, Manuals, Contact Information by Brand - alphabetical list

While the most complete water heater age de-coding charts and tables are in the book and PDF files we list above, here we also list water heater age or serial number decoding charts for particular water heater brands or products requested by readers.

Because some water heater manufacturers (such as American) produce heaters (or calorifiers or cylinders) sold under multiple brands, you may also find your water heater's age decoder by using your browser's On-Page Search feature (Ctrl-F or CMD-F).

For example, Ace, Apex, Aqua Temp, Aqua-Therm ... Tru-Value, Whirpool and more brand names are all produced and decoded by the American Water Heater Age Decoder.

If your water heater does not appear in this list you are welcome to contact us using the page top or bottom CONTACT link and we'll help reseach your question at no charge.

If the serial number in your water heater data tag format does not match what's given in each of these guides, see DATA TAG DECODING ADVICE for NON-STANDARD DATE CODES.

Could be: Ser# 00584865, 06584865, or 0G584865

Reply: best guess 1970.

From Carson Dunlop Associates Associates comprehensive Technical Reference Guide

Chrysler Air Temp Products: see AirTemp and Fedders. In HVAC serial numbers the first digit is a key to the year of manufacture beginning with 1970.

So SN# 42599229 would de-code to be manufactured in 1974

Contact information for Chrysler Air Temp

We have not found a useful current (2015) contact reference for Chrysler Air Temp products. Chrysler Air Temp was sold by Chrysler and AirTemp was purchased by Fedders Corporation in the 1970's. Fedders subsequently sold many of its assets to focus on room air conditioners under brands Airtemp, Climatrol and Fedders. Those products are currently produced in China.

Fairbanks Morse Water Heaters & Appliances

Question: Age & manual wanted for Fairbanks Morse water heater (electric)

2019/03/22 Rene-Philippe Hebert said:

Hi, I'm looking for the age of a Fairbanks Morse water heater model WE39305SE serial 139079-6005, thanks.

Reply:

Rene-Phiippe

I'm researching further but have not (yet) found a Fairbanks Morse water heater age key. From your serial number my guess would be 1979.

Fairbanks Morse & Co. produced a remarkable range of products from radios and pumps and water heaters to washing machines and railroad locomotives.

Fairbanks Morse & Co, (Chicago IL USA) with offices in Australia, England, and in many cities across the U.S. and Canada, starting as a scale manufacturer, was a large 20th century manufacturer of heavy equipment including railroad engines (12-cylinder Fairbanks-Morse Model 38D engine) and smaller engines such as the Fairbanks Morse 2,3, and 6 horsepower 'Z' throttling governor engines.

Wikipedia's current article on Fairbanks Morse cites 3 entities:
Fairbanks Scales is a privately owned company in Kansas City, Missouri, that manufactures scales.

Fairbanks Morse Engine (FME), a subsidiary of EnPro Industries, is a company based in Beloit, Wisconsin, that manufactures and services engines. - Website: www.fairbanksmorse.com/about-us

Fairbanks Morse Pumps is a part of Pentair Water in Kansas City, Kansas, and manufactures pumps.

Currently (as recently as 2019) Fairbanks Morse Pumps were produced under the Pentair name (well pumps & ejector pumps).

It would be helpful if you could add an image of your Fairbanks Morse water heater and a closeup of each of its data tags or labels - one image per comment.

The only image of a Fairbanks Morse water heater we've found is from this 1946 advertisement

Anon:
The manual for your Navien CH180 Tankless water heater is available from the company at the link I gave earlier, or also here at InspectApedia at NAVIEN WATER HEATERS

Navien notes that all of its clearance requriements are in accordance with ANSI Z21.10.3 and the National Fuel Gas Code ANSI Z223.1 / NFPA 54 and CGA B149.1 National Gas and Propane Installation Code. See the illustration here and the table below.
The vent clearance distances for the heater are given on p. 35 in the manual; I'll post two clips here that give distances.

On 2019-06-21 by (mod) - Safety of Navien CH water heater vents that may be snow-covered

A good place to start is with the installation instructions from the manufacturer.
Navien Heater Company has a website with plenty of resources and product instruction downloads https://www.navieninc.com/ - you'll need your specific product type, name, model number, and on occasion, serial number.
1-800-519-8794
or
https://www.navieninc.com

Navien says the heater vent has to be at least 7' above ground, but where there is snow cover you need to be above the top of the maximum anticipated snow depth OR the vent exits need to be protected from being covered by snow by an external means.

Watch out: any direct vent heating appliance whose air intake or exhaust can be blocked by snow or anything else is potentially unsafe and risks fatal carbon monoxide poisoning of building occupants.

On 2019-06-21 by Joe

Here is the direct vent systems that the Kalamazoo, MI city is finding no problem with despite smelling the exhaust inside at times. Especially in winter when these were all but buried.

We can get up to 2 ft snow here at times. They are saying the clearances are accurate, but we are finding they are not. These 3 systems are Navien T loves. 2 are CH 180s and the middle is a CH 210.

All are common vented intake from a window well you will see in pictures(bottom left).

Bushes may be the problem as well. Furthermore the bottom of the vent exhausts come out of the building at ground level behind the bushes.

Being this does not fit the direct venting specifications what kind of setup would this be classified?

What are your thoughts as we seem to be hitting road blocks getting the city to see there is a problem here.

Description: Series 210-5 automatic gas shutoff valves are positive-acting energyshutoff for the emergency temperature protection of gas water heaters.They are self-contained devices independent of all other operating controls.
They provide protection against overheating water in the domestichot water supply heating systems by automatically shutting off the gassupply to the heater in the event that the water temperature reaches210°F (99°C). Series 210-5 must be manually reset in order to resumeheater service.
This feature serves as a warning of malfunctioning of thenormal operating controls. Manual resetting is easily done and does notrequire dismantling or replacing of any part of the valve. See “ResetButton” feature.
This gas shutoff differs from other contemporary design in that Wattsengineers have embodied the time tested Watts auto-thermatic thermalactuator principle along with a snap-acting trip latch which closes thevalve at a definite controlled temperature.

Weil McLain Heater Age De-Coding Guide

Weil McLain Heater Age Query: (Oct 25, 2012) carl said: how do you find an age of a Weil Mclain GV 3 Gold serial no cp 3406659

Reply: this looks like you have sent us a heating boiler brand and model number not a domestic water heater. Quoting product literature:

The Weil McLain GV boiler is a high efficiency, gas-fired direct vent water boiler with cast iron sections.
Using sealed combustion technology, the boiler reduces energy usage by eliminating air infiltration. The GV boiler is easy to install and service, and is useful for a wide variety of applications including residential, light commercial, multiple boilers, indirect-fired water heating, and radiant heating.- pexsupply.com

From Carson Dunlop Associates Associates Technical Reference Guide, the most complete HVAC and water heater age decoding guide I've got (provided courtesy of CDA), Weil McLain heating boiler serial numbers beginning with 34nnnn were manufactured between 1998 and 2000.

This article and comment page are for water heaters. For details on age determination for heating boilers & furances

see AGE of HEATERS, BOILERS, FURNACES.

Watch out: for other Weil McLain boiler numbers one needs to consult the Guide cited above, as the encoding of serial numbers does not afford a formulaic de-code procedure. For example Weil McLain boiler serial numbers beginning with 32nnnnn were made beginning in 1997.

What Determines Water Heater Life?

Home inspectors typically expect a generic water heater to last about ten years. However all of us have found 20 year old models still going strong, while on occasion a newer model fails early.

What are the Typical Terms of Water Heater Warranties

Type of water heater tank and water heater warranty - modern 'glass lined' water tanks are coated to resist corrosion. The manufacturer's warranty is a clue to how long the company expects their water heater tank to last.
Typical water heater warranty periods for a water heater installed for use by a single family are 6-years, 9-years, or 12-years.

But beware: if the water heater tank leaks and fails before the end of the warranty period, if the system has not been properly installed or maintained the warranty may be void.

Water heater warranties typically indicate that the tank is warranted against leaks due to rust, corrosion, or chemical action of the water but the warranty will exclude warranty coverage for the geyser or water heater for

a tank failure due to scale
SCALE REMOVAL, WATER HEATERS
or possibly by failure to maintain the water heater as the manufacturer requires
WATER HEATER DEBRIS FLUSH
or possibly by using the water heater in a manner not intended, such as for home heating
WATER HEATERS for HOME HEATING USE?
The warranty period of a water heater may be encoded in its model or serial number.
For example Lochnivar water heaters include a model number prefix that determines whether the heater is warranted for six years or for ten years. If the water heater is in any other use than one-family residential, the heater is warranted for one-year on parts and three years on the tank itself.
