So, how old IS my water heater?īelow are serial number lookup sections for every major water heater manufacturer. For instance, even though the water heater you bought from Sears says Kenmore on it, it’s still manufactured by Rheem. A small number of manufacturers create water heaters which are then sold under dozens of different brands. The brand on the other hand is what the water heater is sold (or branded) as to customer. The manufacturer is the company that takes materials or components to create (or manufacture) the water heater. This means that at no cost to you, we may receive a small commission for made purchases.īefore going further, I want to point out the differences between a water heater manufacturer and a water heater brand. Note: This post may contain affiliate links. You can access online versions of most models of the three most popular brands at these links: 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).Īlternatively, you can check your manual to get a rough estimate on age based on the copyright year. If you have a newer model, the water heater age is sometimes clearly printed on the manufacturer’s label affixed to the unit.įor everyone else, keep reading to see how easy it is to find your water heater’s manufacture date. If you’re the type who saves every purchase receipt for decades, you probably don’t need to read this. Hopefully your water heater is not THIS old. You may be wondering if repair or replacement is the best option or even if you’re still covered by the manufacturer’s warranty.

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?“.
