Serial number decoder for Bosch (HVAC)
Type the serial from the data plate, not the model number. Nothing is sent anywhere; the tables are in this page.
Format example: FD930356731
- Bosch (HVAC) heat pump serial numbers in the era not stated format encode the year as digits 1-2 after FD + 20, keep last two digits: 93 + 20 = 113 -> 13 -> 2013 (i.e. year = (YY + 20) mod 100; 80-99 => 2000-2019, 00-19 => 2020-2039, 60-79 => 1980-1999) and the week as digits 3-4 per building-center (03 = week 3); possibly month - unverified (source: building-center.org).
- Example: serial FD930356731 decodes to week 3 of 1993.
- Bosch (HVAC)'s official lookup at bosch-home.com returns warranty / registration lookup.

What we could not confirm
- The era not stated format is only partially confirmed (PARTIAL (inspector source only)).
- Bosch (HVAC) is treated as sharing Bosch (appliances)'s format because the source lists it in that family; the corporate relationship itself is an estimate.
- The before 2009 format has no source we could check; it is shown for completeness only.
- The before 2009 format is documented but not decodable here: no year decode text.
- FD number on the rating plate (separate from the E-Nr model number) is the production date: FD YYWW + sequence, with the year offset by 20 (FD 93.. = 2013). building-center calls digits 3-4 the WEEK; some trade sources call it the month - not resolved this session (bosch-home.com US FAQ/serial pages 404; search budget exhausted). bosch-home.com/us/en = 200 (site home only; no serial lookup confirmed).
