Bosch Water Heater Age Decoder

Depending on the age of your Bosch water heater, the dates of production or manufacture are found at different points in the serial number that you will find on the water heater's data tag - as given in the Bosch Serial Number reference guide PDF provided later on this page.

Two Bosch water heater serial number formats are common but you will already notice that these commonly-used Bosch age decoder formats do not exactly match the serial number of the LPG firedBosch tankless water heater data tag shown.

All-Numeric: 12345678 where 123 encodes production monty and year encoded by a table available from Bosch and replicated below.

What you will notice is that for each year the company uses a 3-digit code that incrases by 1 for each month of that year. So for 1996, of the 3 digit code 86 = 1996 and the months suffix 1 - 12 as shown in the table below.

For 1998 the year begins with 861 = 1998 January of 1998 while 872 = 1998 December

Similarly for 2002 the year begins with 381 = 2002 January while 392 = 2002 December

...

Alpha-Numeric: AB123456789 where 123 encodes production month and year encoded by a table available from Bosch and encoding year and month just as for the table given above.

Use the same table above once you've piced out the three nnn digits after the first pair of alphabetic characters such as AB shown abovce.
