Understanding the age of your Bradford White water heater is crucial for proper maintenance, efficiency, and knowing when to replace it. Many homeowners in the United States are unsure about the exact age of their Bradford White water heater, which can lead to unexpected breakdowns or expensive repairs. Fortunately, determining the Bradford White water heater age is a simple process if you know where to look. This guide will walk you through why it matters, how to check it, and what signs indicate it may be time for a replacement.
Why Does Your Bradford White Water Heater Age Matter?
Your water heater’s age plays a vital role in determining its efficiency and lifespan. Over time, sediment buildup, rust, and normal wear and tear can cause your Bradford White water heater to lose efficiency, leading to higher energy bills and potential breakdowns. Knowing the age of your water heater helps you:
- Plan for maintenance or replacements before issues arise
- Prevent costly emergency repairs
- Ensure your water heater is operating safely and efficiently
- Check if your water heater is still under warranty
Most Bradford White water heaters last between 10 to 15 years with proper maintenance. If your unit is approaching or exceeding this age range, it may be time to consider a replacement.
How to Check Your Bradford White Water Heater Age
Unlike some other water heater brands, Bradford White does not print the manufacturing date directly on the label. Instead, the age of your water heater is hidden within the serial number. The serial number contains coded information that tells you when the unit was manufactured.
To determine the age of your Bradford White water heater, follow these steps:
- Find the serial number (usually located on the heater’s rating plate).
- Decode the serial number to identify the manufacturing date.
- Use the first two characters of the serial number (a letter and a number) to determine the year and month.
Understanding how to decode the Bradford White serial number is essential, which we will explain in the next section.
Where to Find the Serial Number
The serial number is typically found on the rating plate of your Bradford White water heater. This plate contains essential details about the unit, including:

- Model number
- Serial number
- Energy efficiency rating
- Capacity (gallons)
How to Read the Serial Number
Bradford White uses a unique letter-number coding system in their serial numbers to represent the manufacturing date.
- The first letter represents the year of manufacture.
- The first number represents the month of manufacture.
Here’s how the letters correspond to years:
LetterYearLetterYear
A 1984, 2004, 2024 N 1997, 2017
B 1985, 2005, 2025 P 1998, 2018
C 1986, 2006, 2026 R 1999, 2019
D 1987, 2007, 2027 S 2000, 2020
E 1988, 2008, 2028 T 2001, 2021
F 1989, 2009, 2029 W 2002, 2022
G 1990, 2010, 2030 X 2003, 2023
For example, a serial number starting with “P8” means the unit was manufactured in August 2018 (P = 2018, 8 = August).
Example of a Bradford White Serial Number
Let’s break down an example serial number:
Serial Number: X5A567890
- X → Year 2023
- 5 → May (5th month)
- The rest of the number is a unique identification code.
This means the water heater was manufactured in May 2023.
How Long Does a Bradford White Water Heater Last?
A Bradford White water heater typically lasts 10 to 15 years. However, several factors influence its lifespan, including:
- Water quality – Hard water can cause faster sediment buildup.
- Usage – Heaters that are used frequently may wear out sooner.
- Maintenance – Regular flushing and anode rod replacements can extend the life of your heater.
If your water heater is older than 10 years, you should monitor it for signs of aging and inefficiency.
Signs Your Water Heater Might Need Replacement
Even if your Bradford White water heater is still functioning, certain warning signs indicate that it may be time for a replacement:
- Rusty water
- Strange noises
- Leaks around the unit
- Inconsistent water temperature
If you notice any of these signs, it may be time to consider installing a new water heater.
Rusty Water
Rusty or discolored water can indicate corrosion inside your water heater tank. This usually happens when the anode rod (a component that prevents rust) is worn out. If you notice rust in your hot water, it’s a strong sign that your Bradford White water heater is aging and may need replacement soon.
Strange Noises
Over time, sediment buildup in the tank can cause popping or rumbling sounds when the heater is running. These noises indicate that your water heater is struggling to heat water efficiently, which can lead to higher energy bills and potential breakdowns.

How to Extend the Life of Your Water Heater
To keep your Bradford White water heater running efficiently for as long as possible, follow these maintenance tips:
- Flush the tank annually to remove sediment buildup.
- Check and replace the anode rod every 3 to 5 years.
- Inspect the pressure relief valve regularly.
- Keep the thermostat set between 120-130°F to prevent overheating.
- Look for leaks and rust around the unit.
Regular maintenance can significantly extend the lifespan of your Bradford White water heater and keep it running efficiently.
The Bottom Line
Knowing the Bradford White water heater age is essential for ensuring safe and efficient operation. By locating and decoding the serial number, you can determine your water heater’s manufacturing date and decide whether it’s time for maintenance or replacement.
If your Bradford White water heater is over 10-15 years old, watch for warning signs such as rusty water, leaks, and strange noises. Regular maintenance can help extend its life, but if your unit is nearing the end of its lifespan, it may be time to invest in a new, energy-efficient model.
By staying informed about your water heater’s age and condition, you can avoid unexpected failures and ensure you always have access to hot water when you need it.
