How To Tell The Lifespan Of Your Water Heater

In our previous post you learned the top warning signs that indicate your water heater may need to be replaced, and one of the most prominent signs is the age of your water heater. In this guide, we'll walk you through the telltale signs of an aging water heater, the repercussions of not replacing your water heater as it approaches its expiration date, and the step-by-step process to discover its true expiration date. Follow these steps to ensure your appliance continues to deliver you a reliable supply of hot water without a hitch.

Why Should You Care About the Age of Your Water Heater?

In addition to the inconvenience of a sudden cold shower, there are serious repercussions to consider. An older water heater is more likely to be prone to leaks, corrosion, and overall malfunction. All of these can lead to water damage, costly repairs, and they become less energy-efficient over time — which can drastically increase your utility bills. The best way to avoid these obstacles? Checking your water heater's age, outlined below.

How to Check Your Water Heater's Age:

1. Locate the Serial Number

The serial number is usually located on the manufacturer's label on your water heater.

2. Decipher the Code

Manufacturers often use a specific code to indicate the age of the water heater within the serial number. Some may use the first four digits to represent the month and year, while others might use a combination of letters and numbers to denote the age.

3. Decode the Date

If your serial number follows the MMYY format, a code like "0519" would mean May 2019. Similarly, if it follows the MMDDYY format and you see "061225," that corresponds to June 12, 2025. For codes with letters representing months (A for January, B for February, etc.), consult a decoding chart provided by the manufacturer to match the letter to the corresponding month and decipher the year.

4. Consult the Manufacturer

If you can't find the serial number or are having trouble decoding it, you can reach out to the manufacturer for assistance or call or text us at (512) 766-1519 to schedule a home visit.

Conclusion

You are now better equipped to assess the age of your water heater. Being proactive about your water heater's lifespan can save you from unexpected breakdowns and costly repairs. If your water heater is approaching the 8-10 year mark, give us a call!
