Buzzing noise before back boiler ignites

[kscottsafc]

Hi all

Been watching this site for a while! I have an old back boiler system that before it ignites makes a loud buzzing noise

Just wondered if anyone could shed any light on this before i call someone out

Thanks in advance!

If it's really old then I can only think it will be the solenoid on the gas valve.

You will need to call an RGI out for any work on this though.

Thanks for that! When it comes to gas etc i go nowhere near it as its best left to experts!! Just after some knowledge so i don't look like an amateur and get ripped off!

No sure how old it is as it was in when we bought the house but i'm assuming its pretty old simply by it being a back boiler!
