Jun 6, 2018 - The date of production/manufacture or age of Rheem/Ruud® HVAC equipment can be determined from the serial number located on the data.
Whether it’s leaking, making noises, or simply not heating water the way it used to, you’ll eventually have some type of water heater problem. Since you probably understand that appliances don’t last forever, one of the first questions you’ll ask yourself when something goes wrong is, “How old is my water heater?“.
To verify your limited warranty registration, enter your product serial number (with no spaces) in the warranty verification tool provided below. Below are serial number lookup sections for every major water heater manufacturer. Column one lists all the various brands that manufacturer makes, column two shows sample serial numbers, and column three of each table acts as a serial number decoder.
You may be wondering if repair or replacement is the best option or even if you’re still covered by the manufacturer’s warranty.
If you’re the type who saves every purchase receipt for decades, you probably don’t need to read this. If you have a newer model, the water heater age is sometimes clearly printed on the manufacturer’s label affixed to the unit.
For everyone else, keep reading to see how easy it is to find your water heater’s manufacture date. All you need is to know who manufactured the water heater and its serial number (both found on the label affixed to the water heater).
Alternatively, you can check your manual to get a rough estimate on age based on the copyright year. You can access online versions of most models of the three most popular brands at these links:
Manufacturer vs Brand
Before going further, I want to point out the differences between a water heater manufacturer and a water heater brand. The manufacturer is the company that takes materials or components to create (or manufacture) the water heater.

The brand on the other hand is what the water heater is sold (or branded) as to customer. A small number of manufacturers create water heaters which are then sold under dozens of different brands. For instance, even though the water heater you bought from Sears says Kenmore on it, it’s still manufactured by Rheem.
So, how old IS my water heater?
Below are serial number lookup sections for every major water heater manufacturer. Column one lists all the various brands that manufacturer makes, column two shows sample serial numbers, and column three of each table acts as a serial number decoder.

How do I tell the age of a Ruud water heater from the serial number?
Tuesday, September 11, 2018
The third and fourth numbers in the serial number, usually after several letters, is the year of manufacture of a Ruud water heater. So the manufacturer’s data plate below indicates that it was made in 1985.
Newer Ruud water heaters, like the one with the label below, make it easy for you: the manufacture date is also stated to the right of the serial number.
Also, see our blog posts How can I determine the age of a water heater if the serial number is missing or decoding it is impossible? and What are the most common installation mistakes with water heater replacement? and Are water heaters required to be raised off the floor? and What's that powdery crust on the pipe connections at the water heater?
