How Old Is Your Revere Water Heater?

Revere is a private-label trade name produced on A.O. Smith lines, so its serial numbers carry the same date code as State, Reliance, and American units: year, then week, in the first four digits. Enter your serial in the free decoder above for an instant answer, or follow the guide below to read it yourself.

Where to Find the Serial Number

Check the rating plate on the side of the tank — a silver or white sticker, usually in the upper half, that lists the model number and serial number together. The date lives in the serial, not the model number. On older tanks the sticker can fade; a phone photo with the contrast bumped usually makes the first four digits readable.

How the Revere Serial Format Works

The date code is year, then week, in the first four digits:

Worked example — 1508B004917:

  • 15 = 2015 (year)
  • 08 = week 8 (late February)
  • B and the remaining digits = factory and production sequence
  • Result: manufactured in week 8 of 2015

Letter prefixes. Some serials start with letters, or insert a letter inside the date block — these are factory codes, not part of the date. Skip leading letters and read the first four digits you find. For example, AB0504C008823 decodes to week 4 of 2005.

The two-digit year can point at two decades — 15 is 2015 on most units but could be 2005 on an older one. Compare the unit's condition and model line; our decoder lists every plausible year instead of guessing.

Why Your Revere Water Heater's Age Matters

  • Lifespan. Tank water heaters average 8–12 years of service. Past that, internal corrosion makes tank failure — and a flooded floor — far more likely.
  • Warranty. Revere tanks carried standard warranty tiers counted from the manufacture date. The serial tells you whether a repair might still be covered.
  • Replacement planning. A unit past 10 years is on borrowed time. Knowing the date lets you shop for a replacement calmly instead of during an emergency.

Frequently asked questions

Who makes Revere water heaters?
Revere is a private-label trade name on the InterNACHI water heater dating chart, built by the A.O. Smith manufacturing family (American Water Heater / U.S. Craftmaster). Its serials use the same year-week date coding as State, Reliance, and American units.
How do I tell the age of a Revere water heater from the serial number?
The first two digits of the serial are the year and the next two are the week of manufacture. For example, serial 1508B004917 means week 8 of 2015 — late February 2015. Letters before or inside the serial are factory codes; read the date from the leading digits.
Where is the serial number on a Revere water heater?
On the rating plate — a silver or white sticker on the side of the tank, usually in the upper half, that lists the model and serial numbers together. If the sticker has faded, photograph it and boost the contrast — you only need the first four digits.
How long does a Revere water heater last?
Tank-style units average 8–12 years. Flushing sediment regularly and replacing the anode rod on schedule can push a unit toward the longer end, while hard water shortens it.
My Revere serial starts with letters. How do I read it?
Leading letters are factory or production-line codes, not part of the date. Skip them and read the first four digits you find as year and week — for example, AB0504C008823 decodes to week 4 of 2005.
