Hairline crack in CH boiler

I think everyone is overlooking the question that Alan Wood posed at the start of this thread.

He wanted to know is there is a short term solution that will see the old boiler through Christmas, now only a matter of days away. It is most unlikely to fail catastrophically in that short time and having nursed an old boiler through to the point where it would no longer light up I would back a leak sealing route for the short period it is needed to hold things together .

He clearly intends to replace it anyway and trying to find a boiler engineer free to make the change in an emergency is usually difficult. .

He should though be making arrangements now for a boiler change and getting the man booked up to do the job. That way any insurance claim for collateral damage should stand up as all reasonable steps will have been taken having discovered the problem

Wrong stuff

Obviously central heating leak sealer is required.

As mentioned in the third (now second) post

Some 70 or more years ago when I was a boy, our solid fuel boiler cracked and leaked. Dad being a handy type, drilled and tapped a parallel series of holes, the length of the crack. He then made a patch using a length of copper to fit, and a rubber gasket. We soon had the heating back on. A similar arrangement might be the way forward at minimal cost. John

Thank you everyone for the opinions expressed which are noted and appreciated.

I have no idea why the crack has occurred but it does only emit a fine spray when the boiler is running. Given its age it is past its sell by date and I will proceed on the replacement path.

Allan, if you were able to post up more information, boiler make, model, even a few images then someone may have a spare part which the currently use as a door stop which would suit your requirements.

Also is the system sealed or open vented.

Alan last year I found a damp patch near our back fire boiler, 40 years old, and it seams a fitting which was a screwed in iron elbow was corroded. I called a plumber and I thought he could replace the boiler as heat only back boilers were advertised a couple of years ago but he said they should be kept well clear of. He suggested fitting a new heat only boiler in the loft which used all the original pipework just putting in a couple if pipes to bypass the old boiler and an electric fire in place of the gas back boiler front. The fitting took two days and the biggest hub was fitting the chimney through the roof. The new boiler actually uses less gas cheaper to run and has a seven year full warranty and it is a heat only boiler.
