Help ! Corroded heat exchanger, boiler condemned

[Brian73]

Just had the engineer round to service my Ferroli combi boiler. The heat exchanger was very badly damaged and the boiler has now been isolated.

Worth repairing with a new heat exchanger unit or replace with new boiler?

Not sure what caused the damage, any ideas?

The boiler is 4 years old.

Dont waste money on a ferolli they are awful boilers!

That looks like it's got a bit hotter in there than it should have done, going by the pictures. As said, better to replace that boiler with something a bit less fragile.
Boilers in lofts, don't you just love em?

It also looks like water has been getting in from the flue!

But they are so bad hardly worth bothering with one like that!

Although if it was my own area I could probably find a used one and fit it for about £200 but only IF there were no other issues and water getting into the flue could be a serious one.

Seems the HE has been getting hot and perhaps due to lime scaling in the main HE ?

We have very hard water in Rotherham. The boiler has been serviced annually but we did have a problem with leaks which were fixed under warranty. The system currently does not contain any inhibitors as it was refilled after a leaky radiator valve was fixed about 18 months ago.

You need a good inhibitor in the heating system and a lime beater on the mains side when the new boiler is installed.

That is soot and was caused through lack of servicing an lack of oxygen.
A good clean could get it up and running again.
Don't listen to numpties who know nothing about boilers or pretend they do.

[jeff the gasman]

Upon a closer inspection you are right baz.

The ferroli domicompact. ..peace of ****. Your condess on right hand side of secondary heat exchanger is also leaking. And a nightmare to fix
