It's easy to find out how old your Baxi boiler is, if you're deciding whether or not it's time to invest in a new boiler.

Look for the sticker with a serial number on your Baxi boiler, probably on the front or inside the front panel.

If your boiler was made after 2003, the serial number should tell you what year it what manufactured, within the 6th and 7th digits. For example, if your serial number is 1234517, your boiler was manufactured in '17, so 2017.
