If you’re uncertain about how to tell how old a water heater is, you’ve come to the right place! The experts at Benjamin Franklin Plumbing have years of experience checking out water heaters for our Ft. Myers, FL customers.
Savvy homeowners learn the age of their water heater so they can plan when to replace the unit or schedule proactive maintenance services.
The first place to look is in the documents from when your water heater was first installed. However, if the previous owner of your home put in the water heater, you might not have this information.
You can check the side of the water heater for a serial number from the manufacturer. The serial number will indicate the year and month your water heater was built.
Why Knowing Your Water Heater’s Age Matters
Ft. Myers homeowners should be aware of how old their water heater is because units provide different amounts of useful service, depending on how they’re configured:
- Tank-style units will operate for about 8 to 12 years
- Tankless water heaters can work for up to 20 years
If you can’t find the serial number or paperwork or remember when you installed the water heater (or when the homeowner before you installed it), chances are good that the unit may already be old enough for you to consider replacing it.
Keep in mind that water heaters become inefficient as they get older, which means they use more energy, increasing utility bills. And the older your water heater is, the more prone it is to failing.
For homeowners who have not arranged annual water heater inspections and maintenance, their units may be even more likely to fail unexpectedly.
Locating the Manufacturer’s Label
Look on the water heater’s side for the manufacturer’s label, which is usually located alongside other stickers that have warnings and energy savings information printed on them.
Check the label to find the date of manufacture or the serial number.
Decoding the Serial Number by Brand
There is no single standard for water heater manufacturers to create serial numbers about when they build their units. They take different approaches to showing the month (or week) and year of production.
Here are details to help you interpret different water heaters’ serial numbers:
A.O. Smith Water Heaters:
If you have a water heater made by A.O. Smith, the first two digits of the serial number stand for the year it was manufactured. The second two digits show what week they built your unit.
Bradford White Water Heaters:
Homeowners with Bradford White water heaters consult the first letter of the serial number to find the year it was built, and the second letter to identify the month of production.
Year:
Bradford White water heater serial numbers use the letter “A” to indicate a manufacturing date of 1984 or 2004. The letter “B” indicates it was built in 1985 or 2005, and so on. The manufacturer repeats the letters every two decades.
Month:
Serial numbers on Bradford White water heaters use the letter “A” to designate they were built in January and “B” for February, and so on.
So, if your water heater’s serial number starts with “BA,” it was built in January 2005 or 1985. At Benjamin Franklin Plumbing, our experienced plumbers are adept at determining if a water heater is new or more than 20 years old, so we can help you figure out the manufacturing date of your unit.
Rheem and Ruud Water Heaters:
Do you have a Rheem and Ruud water heater? This company employs a MMYY pattern for its serial numbers. This means, for example, that a serial number with “0621” indicates a manufacturing date of June 2021.
Signs Your Water Heater May Be Aging
There are performance indicators and physical signs that will show you your water heater is getting old:
- Strange rumbling sounds come out of the unit
- Rust-colored water
- Unit delivers inconsistent water heating
- Water leaks from the heater
One or more of these indications should prompt you to get in touch with Benjamin Franklin Plumbing so we can send a plumber over to inspect your water heater. Our team will determine if your unit should be repaired or replaced.
