How to read a Ruud serial number

2012–2026 format
Ruud water heaters made since 2012 have a serial that starts with a factory letter, then two digits for the week and two for the year, then five more digits. For example, Q231299996 was made in week 23 of 2012. If the serial begins with extra letters (such as RU), skip to the last letter before the digits.

Ruud water heater recalls
Recalls come from the U.S. Consumer Product Safety Commission. Decode your unit above to check whether its model and serial fall inside a recall.
Should you repair or replace it?
Once you decode your unit, we compare its age against its typical life, a typical major repair against the cost of replacing it, and, with your model and state, what a new unit would save on energy. A common rule of thumb: if a repair costs more than about 30–50% of a replacement and the unit is past mid-life, replacing usually wins.
