Reader question: what is the life expectancy of a Rheem hot water cylinder
(Oct 26, 2012) meme said:
How many years should a Rheem hot water cylinder last
Reply:
Meme, Rheem's warranty period for hot water heating equipment (cylinders, geysers) varies by product series but is typically 5-10 years.
You will need your product name and model number as well as serial number to look up the exact information for your unit. For example, the HPWH has a 10-year tank leak warranty and a 10-year parts warranty and a first year in-home labor warranty is included as well.
Rheem Age Serial Number
Some Rheem heating equipment such as gas furnaces includes longer periods for the heat exchanger, such as 20 years or 'lifetime'.
You should be sure to register your hot water cylinder at the company's website as that will aid in any future warranty claim. You can call Rheem directly for help. In North America call 1-800-621-5622 and listen for the prompt to take you to warranty information provided by the company
Reader question: decode the age on this 1950's Rheem water heater Serial #B950-3138 RCY-5
2018-02-27 Nick said:
Trying to determine the age of a water heater in my house. Rheem Model #62-52-D; Serial #B950-3138 RCY-5.
The serial number format does not match the Rheem age encoding scheme above on this page.
The # on the unit is B950. Baltimore - September 1950, posssibly. I know the unit is at least 40 years old.
Nine Rheem Water Heater Serial Number Decoding formats
Thank you for the added information, Nick.
I will continue researching to see if we can find a key to older Rheem water heaters that pre-date the modern date encoding schema.
Because Rheem water heaters or calorifiers or geysers were sold under quite a few brands and over many years, there is a plethora of Rheem water heater serial number formats.
Rheem provides their own Rheem water heater age decoder at https://www.rheem.com/how-old-is-my-water-heater however we found that this web page does not work on older Rheem water heater serial numbers.
To date we have found at least nine Rheem water heater age encoding schemes depending on the era of manufacture and also on the type of water heater. We summarize these below.
Photo: an older Rheemglas Standard water heater, Serial No. # R 0884B10488 decodes to August 1988.
[Click to enlarge any image]
- Rheem current 10-digit serial number code: MMYYP12345 where
P is the plant code and 12345 a consecutive unique ID and of course MM YY are month and year of production.
This serial number may be prefixed by R, RN, RNG, RHNG or other letter combinations. - Rheem 8-digit serial number: 1234WWYY ?
Uncertain, possibly WWYY are week number and two-digit year number for older Rheem water heaters like the Rheemglas glass lined water heater - Rheem 9 digit serial number code with alphabetic prefix: ABCDMMYY2345
MM and YY are the month and year of production.
ABCD in this serial number format may be 1 to 4 alphabetic characters in length: R, RN, RNG, RHNG, RHUNM or other letters. The MMYY are the first numeric characters in the code.
Example: RN 1292A29282 - 12 92 or December 1992
Alternative Rheem 9 digit serial number code using week number, with initial character: ZWWYY12345
WW is the consecutive week number (1-52) and YY is the two digit year code - Rheem 10 digit serial number code without plant code: MMYY123456
MM YY are month and year of production.
This serial number may be prefixed by R, RN, RNG, RHNG or other letter combinations.
Alternative Rheem 10-character serial number code without plant code: MM.YY-123456
MM.YY are month and year of production.
This serial number format is used on some Rheem tankless water heaters. - Rheem 11-character serial number code with plant code: MMYYP123456
MM YY are month and year of manufacture, P is a plant code.
This serial number is used on certain Rheem tankless water heaters. - Rheem 12-character serial number code: B950-3138 RCY-5
This serial number was provided by reader Nick 2018-08-27 and has not been precisely de-coded.
Nick adds that the heater was made on or before 1978 and he speculates tht the B950 could refer to B-Baltimore and 950 to 9 - September and 50 - 1950.
However Rheem does not have and appears not to have had a manufacturing facility in Baltimore, Maryland. - Rheem 16-character serial number code with plant code: ZMMYYP12345689X
MM YY are the month and year and P is a plant code.
Decoding Older Rheem Water Heater Data Tags

Nick
Typically on a Rheem water heater thte age is encoded in a 10-digit serial number as MMYYa12345
Your heater's serial No. is B95-3138 RCY-5 which of course doesn't fit the schema of newer Rheem units.

Thanks again. The only reason I speculated about Baltimore is because it was listed on the nameplate along with 5 other cities (Los Angeles, New York, Baltimore, San Francisco, Chicago, & Houston).

I researched Rheem's history and it looks the they stopped using the logo pictured on the front of the unit sometime prior to 1960.
Thanks for your reply. Here is the nameplate. I'll get some pictures of the unit itself tonight.

This article provides documents that explain and translate all of the data found on information tags and stickers used on heating & heat pump equipment, including equipment age, heating capacity, electrical requirements, and operating characteristics.
We also provide a MASTER INDEX to this topic, or you can try the page top or bottom SEARCH BOX as a quick way to find information you need.
Heating System Equipment Age - Guides for Reading HVAC & Water Heater Equipment Data Tags & Serial Numbers
If you don't know whether your heat is provided by a furnace (hot air) or boiler (hot water), or whether your fuel is oil, gas, or electric, and whether your heat is hot water, steam, or warm air, see HEATING SYSTEM TYPES.
Then return to this page for help finding the equipment's age or date of manufacture.
Five HVAC Heating & Air Conditioning Equipment Age & Data Tag Decoders
Our photo shows data tags on a Weil McLain gas fired heating boiler that was manufactured on 10/10/1996. [Click to enlarge any image]
We found the boiler age by de-coding the boiler's CP/serial number code on the white sticker just above the data tag. Below we explain how we did that.
For help in decoding air conditioner, boiler, furnace, heat pump, water heater data tags and determining the age, model, or specifications of that equipment, we provide five different research methods listed below.

If the boiler was manufactured from 1984 to 1999, the serial number ends in a four digit date code. “123456-1284” would be manufactured in December, 1984.
If the boiler was manufactured from 2000 to present, the serial number ends in a six digit date code. “123456-200505” would be manufactured in May, 2005.
- Weil McLain Heating Boiler Age Decoder, at https://www.weil-mclain.com/cp-lookup will decode the heating boiler's CP/Serial Number. At the company's website you will find these instructions:
Enter the 7-digit CP/Serial Number of the boiler to obtain the manufacturing date and any associated information on the product.
If the CP# is only 6 digits, enter a leading zero, e.g. 0137718. This look-up will not give manufacturing information for any other Weil-McLain product but boilers. Currently, no information is available for EG and EGH boilers.

The Carson Dunlop Technical Reference Guide provides both equipment data tag decoding data and also manufacturer contact information as well as historical dates for many brands of heating and cooling equipment. Included in the manufacturers listed are also makers of ancillary equipment such as controls, circulator pumps, etc., not just boilers, furnaces, and heat pumps themselves.
The age of a heating boiler, furnace, or heat pump can be determined by identifying its year of manufacture that is encoded in the unit's serial number (not the model number). The guides above give heater serial number decoding for each manufacturer and type of heating appliance.
For example, when decoding the age of an H.B. Smith heating boiler one of our readers provided the following from his boiler's data tag:
H.B. Smith, Westfield MA
Series G200
Boiler Model # G200-W-5CON
Serial # J80-2747
Series G200
Boiler Model # G200-W-5CON
Serial # J80-2747
For an HB Smith boiler the age is typically the two digits following the letter at the beginning of the serial number. In this case the '80' following the 'J' tells us that the boiler was manufactured in 1980.
Later H.B. Smith boiler serial numbers use the format XXyyyy-nnnn where yyyy will be the four-digit year of manufacture.
Manufacturers & brands of HVAC Equipment and Parts identified and decoded in the CDA Technical Reference Guide include about 128 different brands of equipment sold in North America

Illustration of a Warn Air Heating System Using a Gravity Furnace
Our photo (left) shows a gravity warm-air 'octopus' furnace; in its earliest version these furnaces, installed in the late 1800's in the U.S. were coal fired; many were later converted to oil.
Gravity furnaces rely on natural convection (warm air rises) to deliver heat to the occupied space.
There is no blower fan in the system. In their simplest design, the gravity furnace system included no ductwork whatsoever. Rather a large grate was provided in the building floor just above the furnace itself. In a multi-story house, heat rose to upper floors by passing up the stairwell or through open registers in first floor ceilings.
The gravity furnace we show at left was a more advanced design in which an 'octopus' of duct work 'arms' delivered heat directly to individual areas of the building.
The furnace in our photo is taking much of its 'return air' from the basement - a very expensive way to heat a home. Earlier models eschewed ductwork and instead fed heat into the first floor of the building through a large central grate in the floor immediately above the furnace.

Beginning at HEATING SYSTEMS - home we discuss different types of heating systems such as
- AIR CONDITIONING & HEAT PUMP SYSTEMS - heat pumps and air conditioners
- BOILERS, HEATING - hot water or 'hydronic' heating systems
- CONDENSING BOILERS/FURNACES- high efficiency hot water heating boilers
- ELECTRIC HEAT - electric baseboards, furances, convectors
- FURNACES, HEATING - forced or gravity warm air heating systems
- STEAM HEATING BOILERS- steam heating systems
We also discuss various heating appliance fuel types (coal, oil, gas) as an aid in determining the age of a home or other building.
Antique Gas-Fired Floor & Wall Heater
Reader Question: Royal Heater in-floor gas fired heater history
I just bought a home in California. It has a dual sided, vent less, gas floor heater.
[Click to enlarge any image]
The only name I see is ' Royal Heater'. there are 2 valves; one for burner, one for pilot.
You need a key to turn them. On top of the unit is a view finder cap. Inside it looks like a 3 burner pilot
. I have attached photos of it. I'm trying to find any information on it. thank you.
[This particular heater] works beautifully and has been inspected. I want to find a operator's manual so I can maintain it.

Reply: history of Royal Metal Works gas fired floor heaters in California
G.L.
The Royal brand in-floor gas heaters were originally designed in California in the late 1920's - we have a patent (Publication No. US1666367 A) by Louis Clausing (Burlingame CA) assigned to the Royal Metal Works (his own company held in partnership with Max Schwartz describing an earlier version of the product dated 1928: 'Heating device.' U.S. Patent 1,666,367, issued April 17, 1928.
Your photos below illustrate the interals of this floor-wall gas heater.
That that company was Royal Metal Works, 238 Van Ness Ave, in San Francisco, CA. That patent was cited by other product patents between 1943 and 1982.
Below at left your photo shows the gas controls including main valve (left) and pilot valvce (right-hand stem). At below right you've shown the pilot flame (I think).
The company filed just three patents, two for heaters and one for metal bending:
- Publication No. US1666367 A - heater 1928 (filed 1923) [PDF]
- Publication No. US1700559 A - heater 1929 (filed 1923)
and
- Publication No. US1808019 A - an interesting method for bending corrugated metal - 1931 (filed 1929) and perhaps involved in the manufacture of the heaters in the earlier patents.

There is presently a [different] California Royal Metal Company (in fact several of them)
who might be able to give you more historical data, is a sheet metal fabricator whose business was established in 1981 but who may have known of the older Royal Metal Works who made your heater:
who might be able to give you more historical data, is a sheet metal fabricator whose business was established in 1981 but who may have known of the older Royal Metal Works who made your heater:
Royal Metal, Ted Rieck Enterprises Inc, 1228 South Wright St., Santa Ana, CA 92705 USA Phone: (714) 542-4763 Web: Royalmetal.com
Unless you object, I'll add your photos to data we have at InspectApedia and will leave you anonymous (our default) unless you let me know that you want to be identified. That may attract comment from other readers who have similar products.
I'll attach the documents of interest to this article.
Watch out: I would not assume that the heater you have is safe to use without both a thorough visual inspection and testing for gas leaks as burning LP or natural gas in a defective appliance can produce fatal carbon monoxide gas.
I would suspect that your device may also lack safety features of modern gas heaters. If you are going to ignore my timid warnings then at least be sure you have working CO and smoke detectors properly located and installed.

Heating Equipment Data Tag Location & Identification
This discussion explains where to find the data tag on air heating equipment.
To see specific details for your heater (boiler, furnace, heat pump, etc) you will need to know the brand and hopefully the model, then see
AIR CONDITIONER BOILER FURNACE AGE, MANUALS & PARTS GUIDES - HVAC
AIR CONDITIONER BOILER FURNACE AGE, MANUALS & PARTS GUIDES - HVAC
Heating equipment data tags are usually found on the exterior of the heater, usually on its top, front, or sides.
On occasion you may find the data tag information inside of the heating device, accessed by opening a removable front cover.
Often by removing the front cover of a forced warm air furnace, the equipment data tag is found inside the furnace jacket on the left, right, or directly on the exposed face of the furnace itself.
In our first photo shows gas fired heating boiler located in a garage.
The yellow arrow points to the common location of the equipment data tag on the upper left side of a Weil McLain heating boiler. [Click to enlarge any image]
Our second photo above shows the common location for the equipment data tag (circled in yellow) on a Peerless cast iron boiler.
On this page we illustrate typical equipment data tags on heating boilers and furances.
Our first photo below shows the data tag for a Smith Cast Iron Boiler.
You will find the model number identified on this heater as SERIES 19A SERIES-S/W-5, and SERIAL NUMBER FA2002-533.
Our second photo below shows the data tag on the exterior of an HB Smith heating boiler, Model BB14-*-4, (the * indicates that this is a steam boiler), though in my over-shot photo the serial number is not quite visible.
Furnace Data Tags Often Are Behind An Access Cover
Some gas furnaces sport a data information tag on the furnace interior left or right side, visible only after removing the front cover.
Below is the data tag for a rusty old Holland gas furnace, visible on the front of the furnace above the gas burner tubes, accessible only when the furnace front cover door has been removed.
Other Information Tags Are Not Equipment Data Tags
Watch out: not all of the information labels, tags, stickers seen on and in heating appliances are data tags. Don't get confused and don't think that because you cannot find the model and serial number on a label that the equipment has no data tag.
Look further on the outside and inside of the device. A true 'data tag' includes brand, model name, and serial number, often along with other information.
Other labels on heating equipment may give warnings or usage instructions, like the label I show below. This sticker gives model and oil burner nozzle guide information for System 2000 boilers by Energy Kinetcs - a boiler I installed in a New York home nearly 20 years ago) but this is not the unit's data tag.
Taking a further look around this same System 2000 Energy Kinetics boiler we spot the actual boiler 'data tag' giving its model and serial number on a smaller sticker that I show below.

Age of the Boiler or Furnace as an Indicator of Building Age
Example of How to sort out shared names such as Flamemaster & Climate Master
If the heating equipment in your building is original - which may be determined by visual inspection, by knowing the building age, or knowing the heating system age, then each of these can inform us about the probable age of the other.
For example, an original Flamemaster (or Climatemaster) gas fired heating furnace is probably 40 or more years old even if you cannot find the date code in the furnace serial number.
Watch out: Names and who is using them can change over time: for example the name 'Flamemaster' appears on other products such as sealants, coatings and packaging produced by Flamemaster in Pacoima California, US - not a heting equipment manufacturer.
The product line Flamemaster gas furnaces shared product designs with ClimateMater. ClimateMaster continues in business (in 2015) as a manufactuer of geothermal heat pump systems.
- Bow Valley Resource Services, Ltd., Flame Master Gas Furnaces, (previously a 1960's company named Hi-Tower) a Canadian firm in Calgary, Alberta, also previously filed for activcity in the U.S. in California, no longer active.
This company may have also produced model 394 & 396 Natural-Draft Flame-Master gas furnaces and gas furnaces sold under the brands of Bryant, Day & Night, and Payne Furnace brands. Estimated cessation 1986.
