Leeking Vaillant ecomax 824 E

[Ponter Boddit]

I have a drip coming from the bottom of the heat exchanger when the burner has been on for a while.
Will the heat exchanger have to be replaced or could it be a seal? And is it worth doing as it's an expensive part and and it's an old boiler?

Thanks Iain

Your condensate is blocked

You shouldn't be taking the cover off your boiler - it forms the safety room seal and should only be removed and refitted by someone who is capable of carrying out the Regulation 26.9 tests, IE a Gas Safe Registered engineer.

The leak is from a seal which should be replaced at a maximum of 5 yearly intervals as part of the standard service schedule, along with another larger seal above it. Personally I don't like leaving them longer than 3 years between replacements. Cost for the pair is about £25. If your bottom one is leaking, you're almost certainly getting carbon monoxide leaking from it too, which is one very good reason why you shouldn't be taking the cover off...

Ok thanks! I'll get Gas registered guy out to fix it.

Step 1 would be to put the cover back on and carry out safety checks required by the gas safety installation and use regulations 1998, regulation 26.9. This looks like a condensate leak from lack of servicing (my opinion from what’s visible). Outweigh cost of repair vs new boiler - whichever you decide, make sure you maintain it.

Blocked condense & new graphite burner seal needed. (And a good service) It has been changed in the past hence the worn out sticker in the picture. Very early model, it's done well.
