If you own an AO Smith water heater, you might be wondering about its age and how to determine it. Knowing the age of your water heater is essential for maintenance, warranty claims, and deciding when to replace the unit. In this article, we will explore everything you need to know about AO Smith water heater age, how to find it, and why it matters.
Why Knowing Your AO Smith Water Heater Age Matters
The Importance of Water Heater Age
Water heaters, like all home appliances, have a limited lifespan. Typically, an AO Smith water heater lasts about 8 to 12 years depending on the model, usage, and maintenance. Knowing your water heater’s age helps you:
-
Plan for replacement before a breakdown occurs.
-
Check if your unit is still under warranty.
-
Understand maintenance needs based on its age.
-
Prevent costly water damage from unexpected leaks.
When to Replace Your AO Smith Water Heater
If your water heater is nearing or past 10 years old, it’s wise to start thinking about a replacement. Older units are less energy-efficient and more prone to leaks or failure. By keeping track of the unit’s age, you can avoid inconvenient outages and high repair costs.
How to Find the Age of Your AO Smith Water Heater
Step 1: Locate the Serial Number
To determine the age of your AO Smith water heater, the most reliable method is to look at the serial number on the unit’s rating plate. The rating plate is typically found on the side of the tank near the bottom or the front.
Step 2: Decode the Serial Number
AO Smith uses a specific format to indicate the manufacturing date within the serial number. Here’s how to decode it:
-
The first two digits usually represent the year.
-
The next two digits indicate the week of manufacture.
For example, a serial number starting with “1912” means the unit was manufactured in the 12th week of 2019.
Step 3: Confirm with AO Smith Customer Support
If you find the serial number confusing or want to double-check, you can always contact AO Smith customer service with your serial number for confirmation on the manufacturing date.
Typical Lifespan of AO Smith Water Heaters

Regular maintenance such as flushing the tank and checking the anode rod
Factors That Affect Water Heater Age

Strange noises like rumbling or popping

Leaks around the base of the unit

Energy Efficiency Drops Over Time
Older water heaters use more energy to heat water, which increases utility bills. Replacing an old unit with an energy-efficient model can save money in the long run.

Warranty Information Based on AO Smith Water Heater Age
Understanding AO Smith Warranty Coverage
Most AO Smith water heaters come with warranties ranging from 6 to 12 years, depending on the model. Warranty coverage typically includes the tank and parts, but not labor.
