How Old Is My A.O. Smith Water Heater?

A.O. Smith® has been manufacturing commercial and residential water heaters and boilers for 148 years and is still one of the world’s leading producers. A.O. Smith® offers a diverse product portfolio that includes several of the industry’s most well-known names such as Whirlpool, Reliance, and Kenmore. This information is included in your comprehensive report from HOMESHAPE Inspections in every home inspection report. It’s critical to know how old your water heater is, because many water heaters only last 12-15 years before needing to be replaced.

How to determine the date of production/manufacture or age of A.O. Smith® Water Heater(s) from the serial number

The simplest approach to ascertain the age of any water heater is to look up the serial number; in some cases, the manufacture date is displayed on the data plate of various brands. This article will help you figure out how old your A.O Smith water heater is.

In many circumstances, the data plate or label for any water heater can be found on the top or bottom of the appliance. The data plate was situated near the bottom of the water heater in this photo on the right. We use these data plates as home inspectors to identify not only the age of the water heater, but also other pertinent information.

Serial Number Decryption Method:

The Date of manufacture is coded in the 1st four numerical digits of the serial number. The first set of numerical digits represent the year, and the second set of digits represents the week of manufacture.

Style A: 1210A002243

Style B: S1318 F000046

Style C:  1836111786352
