Is your boiler acting up? Want to know if it’s time for a new one? The key is knowing how old your boiler is. In this guide, we will be discussing how you can find the age of your boiler.
So, stick with us and let’s discover how you can find out “how old is my Worcester Bosch boiler?”(or any other brand). Let’s discuss the ways to find out boiler age from the boiler model and by assembly week number.
Why Does Your Boiler's Age Matter?
Let’s face it – old boilers cause problems:
- Your bills are sky-high! Old boilers waste gas and make your energy bills soar
- Safety risks grow after 10 years when parts wear out
- Breakdowns happen at the worst times – like freezing winter nights!
- Repairs cost more than they should – sometimes more than a new boiler!
Most boilers last about 10-15 years. If yours is getting up there in age, it’s smart to know before it quits on you.
Quick Way to Find Your Boiler's Age
The easiest way to find out how old your boiler is to look for its serial number. Here’s where you should look for the serial number:
- Check the front – many boilers have a sticker right on the front panel
- Look under the flip-down cover – Worcester Bosch often hides it here
- Peek at the bottom of the boiler for a pull-out tag
- Check your papers – the manual or install certificate shows the date
Got the serial number? Great! Now let’s crack the code!
What's Your Worcester Bosch Boiler Telling You?
Worcester Bosch makes it easy to spot your boiler’s birthday:
- Find that long 25-digit serial number
- Focus on digits 11, 12, and 13
- These magic numbers tell you when your boiler was manufactured
For example: Serial number: 77161301556842205631
- The “8” means 2018
- The “4” means April
- The “2” means week 2
So this boiler was made in early April 2018!
How Old Is My Baxi Boiler?
Did you get a Baxi boiler? Here’s how to find its age:
- Spot the serial number on the sticker on the boiler
- The first number often shows the year
- The next two numbers show the week’s number
For example: Serial number: 901456789

- “01” means Week 1
Your Baxi boiler was made in the first week of 2019!

For older models (pre-2015 Logic boilers), the code is different. If you’re stuck, call Ideal with your serial number!
