Leaking Potterton Promax SL heat exchanger manifold

[bolst3r]

So, I thought my boiler was dead, as it had a leak and needs resetting once a day. A plumber who replaced the ignition a few months ago said my exchanger was leaking and would ultimately need replacing so I was getting quotes to swap.

but...

A different plumber came out today, and said it actually looks like the heat exchanger inlet manifold is leaking onto the controller below which is causing the lock-out, so why don't I just replace the gasket?

So my question is, is this a fault that comes up from time-to-time, and am I lucky this new guy has identified this as the potential issue? How successful is this as a fix, or does it end up invariably being more complex than this? I don't want to throw good money after bad, so if this is a known issue/fix I will be really happy.

I don't want to go the cheap route but i'm currently unemployed so looking for the most economical solution.

Its not a straightforward repair. There is a very good chance that the manifold bolts will be fused into the heat exchanger and will snap when removed. Once that happens, its really game over. The whole heat exchanger could be replaced but a new boiler is a much better option.

@Elkato531

it's not work messing with the exchanger, but I guess when I look at the leaking manifold it could be something as simple as a £10 gasket. Seems a shame to bin it, if that's the case. I totally get your point about seized bolts...

I'm going to have to give this one a little thought. In my mind I was going to replace the boiler, maybe it's worth trying this first. Worse case i'll have to isolate it and use the immersion for a week or two until a new boiler can be fitted.

I wonder if anyone out there has had success with changing this gasket.

Replace it, unless you’re on an insurance contract. They’re a pain in the arse to replace.

no insurance contract. Just trying to decide the best way forward. It's 13 years old... good money after bad?

Well it was a truly awful boiler when brand new. If its 13 years old and probably knackered, get rid.

Sorry, maybe a bit harsh. It could have given you 13 years of problem free service but everything has a lifespan.
