boiler change do i need to change flue aswell

[Chellvic]

i am changing a 15 year old ideal isar 24he combi boiler, it has a vertical flue with bends and extentions on going through a wall and roof, can i swap the boiler but keep the same flue, thanks

What boiler brand are you having? Either way, I doubt the existing flue can be re-used.

i was going to get another ideal boiler if i could keep same flue.

That might be a conversation for your installer or Ideal technical. I don’t know enough as I don’t install, just repair.

ok, well the problem i have is there is no lcd on the display panel and i took it to be checked and they said it was working fine, the boiler turns on but does not seem to fire up, no hot water or heating. i have also noticed some black goo stuff around the base of a brass part where a wire goes into i will try and upload a pic if you have any ideas as i would rather buy a new boiler after christmas if possible, thanks

The black stuff/goo looks like a small leak. As for the display and lack of heating or hot water - I would check the mains connection, these are a small white plug in type, test for voltages and continuity
