Boilers

Which Baxi boiler do I have?

The easiest way to find out which Baxi boiler you have is by looking at the instructions that came with it.


It is always worth keeping these in a safe place, because they also include the Benchmark Checklist that your installer should have carried out when they fitted the boiler and also the boiler’s service history, which should be completed by the engineer when they carry out your annual service.


However, if you no longer have the instruction booklet, the serial number on the boiler provides all the information about the make, model and age of the boiler. It can usually be found on a sticker either on the inside of the drop down panel or on a pull out tag underneath.


You can then contact Baxi Customer Support with the serial number and we can assist you.
