How can I tell age of Bosch water heater from serial number?
Friday, May 22, 2020
The first two numbers in the serial number of a Bosch water heater are encoded to give you the year of manufacture for water heaters manufactured before 2010. They may be at the beginning of the serial number or after a couple of letters. The first number is the year of manufacture, and the second number is the decade encoded, with 6 = 1990s and 8 = 2000s. So 585012459 is 2005, and FB76009742 is 1997. The actual date of manufacture is clearly stated on the data plate beginning in 2010.
To determine the age of another manufacturer/brand of water heater, go to How do I determine the age of my water heater? Also, see our blog posts How can I determine the age of a water heater if the serial number is missing or decoding it is impossible? and What are the most common installation mistakes with water heater replacement? and Are water heaters required to be raised off the floor? and What's that powdery crust on the pipe connections at the water heater?
