How can I tell how old my water heater is? That’s a question on the minds of many Miami, FL, homeowners that we get calls about all the time at Benjamin Franklin Plumbing.
It’s important to know the age of your water heater, in order to plan when to replace the unit or determine when to schedule maintenance services next.
The first place to look is the paperwork that arrived with your water heater during installation. But if this documentation is unavailable, examine the side of the water heater tank to see the manufacturer’s sticker with the serial number printed on it. The serial number should show you the date of manufacture.
Why Knowing Your Water Heater’s Age Matters
Miami homeowners should be aware of the age of their water heater, since the type of unit indicates how much service life it can deliver:
- Tank-style units usually operate for about 8 to 12 years
- Tankless water heaters typically work for up to 20 years
Note that if you are unable to find the manufacture date from paperwork or the serial number, it’s a good idea to consider that your water heater may already be so old that it needs to be replaced.
Consider that how old your water heater is will affect how efficiently it operates. Older units use more energy to keep your water hot, so you’ll pay more for monthly utility bills.
Furthermore, older water heaters are subject to failure at higher rates than new units, underscoring the benefit of knowing the age of your unit. Homeowners who do not schedule annual inspections and maintenance with Benjamin Franklin Plumbing can assume their water heater may fail sooner than units that get checked out regularly.
Locating the Manufacturer’s Label
Check the side of the water heater for the serial number printed on a sticker, usually affixed to the tank next to warning and energy savings stickers.
Your tank’s label might list the manufacturing date. Or, it could show a serial number that you’ll need to decipher to find out when the company built it.
Decoding the Serial Number by Brand
There’s no standard way for manufacturers to create serial numbers for their water heaters. What follows is advice for decoding different manufacturers’ serial numbers and learning how old their water heaters are.
A.O. Smith Water Heaters:
The serial number begins with two digits that indicate the year of manufacture. The second two digits refer to the week it was built.
Bradford White Water Heaters:
A Bradford White water heater’s serial number begins with a letter to note the year of production, with a second letter indicating the month.
Year:
Water heaters built by Bradford White in 1984 or 2004 use a serial number beginning with the letter “A.” Those made in 1985 or 2005 start with the letter “B,” and so on. The company recycles its serial number letters every 20 years in this way.
Month:
Production runs in January get a serial number with the letter “A.” When they’re built in February, the serial number uses the letter “B,” and so on.
So, if your water heater from Bradford White begins with “AC,” it means they built the unit in March of 1984 or 2004.
The professionals at Benjamin Franklin Plumbing will help you determine when your water heater was constructed if you have difficulty interpreting the manufacturer’s serial number.
Rheem and Ruud Water Heaters:
This company follows a MMYY (month and year) format for serial numbers. So a serial number showing “0220” indicates Rheem and Ruud built your water heater in February 2020.
Signs Your Water Heater May Be Aging
There are specific signs that your water heater will show if it is starting to become old:
- Water appears with a rusty color
- Strange, rumbling sounds come out of the unit
- You detect water leaking from the tank
- Temperature is annoyingly inconsistent
If one or more of these signs occur with your water heater, it’s time to contact the experts at Benjamin Franklin Plumbing. Our plumbers specialize in water heater inspections and we’ll let you know if it’s better for your budget to replace or repair the unit.
