Serial number lookup

What does my water heater serial number mean?

The serial number is more than a tracking code — for most brands the leading characters encode the manufacture date. Because every manufacturer uses a different scheme, start with your brand to apply the correct decoder.

How serial decoding works

  • Find the rating/specification label on the side of the tank.
  • Read the serial number — note whether it starts with letters or digits.
  • Pick your brand below to apply the right date-code rule.
  • Confirm anything ambiguous with the manufacturer's official lookup.
