Vaillant ecotech pressure failure

It would have been wise to disconnect the condense and divert it into a bucket and discharge pipework into another bucket whilst you were away and the boiler was off. Water in either bucket upon your return would have ruled certain things in or out.

You can still do this but boiler has to not run to check discharge from condense is/is not leak related.

No leaks in the house, I keep checking.
If system was off, valves would be closed? So pressure drop has to be the boiler?
Starting to get annoying.....

If system was off as in just turned off, then no valves would still be open - something you have to manually close

Today's test, isolated the tank and not using hot water whilst watching the levels in the header tank and the overflow pipe to see if the coil has ruptured.....jury still out

Really confused, do you have a system boiler, combi connected to a cylinder? What system do you have? You mentioned the pressure on the boiler.

It's a boiler with a tank not combi, a pressurised system.

So, next installment, boiler lost pressure once isolated manually and switched off. Checked the condense pipe and water was dripping from it after 24 hours and having been repressurised. Have made assumption that it's the heat exchanger....

Sounds like it, but that's not great news though!

And, worth noting... Heat exchanger can leak straight down into the condense sump and not be evident to other indicators on the sealed system.

Well done you
Thanks to you all in fact, I know nothing about all this, purely what I've ascertained from Google and you folks but it seems that amounted to more than my heating engineer he says he's never seen this before
I'm going to have to rely on him to fit the new one but he seems better with actual bits rather than diagnostics......

Any contractor doesn't like uncertainty, give them a specific defined task and you'll get an accurate quote and a quick job. Anything involving unknown quantities and repeat visits and it suddenly becomes hard to justify. Contractors make money by charging the value of the job but doing it job better and quicker than average. so if they don't feel like they'll be able to do that they lose money.
This is why boiler swaps are more attractive as the value of the job is higher and it's very predictable.

You're generalising there.
For the majority of us plumbers, there's the desire of the inner engineer, to fix things and make them work properly.
It isn't ALL about the money, but financial pressures on both parties (us and the customer) makes the decision of when to repair or replace, one of great debate... Believe me, I'm often pondering such decisions whilst laying awake at 3am!

Sorry yes good point @dilalio i was meaning contractor in the generic sense rather than the actual individuals who do the jobs and enjoy plumbing and problem solving and have empathy and generosity to customers!
