Hi
I'm new on this forum so my apology if this is not the correct etiquette. Earlier I thought I was posting this question on a forum but think I actually "started a conversation" with Scott)
I am looking for advice on Viessman 111W corroding hoses.
Background:
I currently have a 19 year old Baxi Maxflow combi which, like the Viessmann 111W, has an on board ~ 50 Litre storage cylinder. As a concept it works well for us as we understand it. It needs replacing so I looked for a similar system and came to the Viessmann 111W. All was going well and then one plumber mentioned the “corroding rubber hoses” on the flow and return. Long story short, after investigations and mentioning this to a few installers a number of them had seen the issue or had mates who had seen the issue. (coincidentally I was speaking with a man I met and he has a Viessmann system boiler which after 2 years had exactly that problem too).
I spoke with Viessmann who were quite defensive on the subject blaming the installers for not installing the boilers correctly (blamed it on too much inhibitor!). The chap I spoke to then admitted that they had now changed from rubber hoses but said the 111W still had one rubber hose left in it. All this rather put me off Viessmann as the attitude seemed strongly to be: “we’re right everyone else is wrong”. (I have seen this with some other German suppliers suppling into the UK market where things may be done differntly to Germany). I also heard that their spare parts such as circuit boards are very expensive (I heard a tale of one board costing £950!).
However the modulation range of the boiler is great, the guarantee of up to 10 years is good and the stainless steel HEX attracts me.
But I am still very nervous about
Would any of you have any advice/experience to confirm my thoughts or to disabuse me of them?
Thanks Gerry

But I am still very nervous about
- Corroding hoses,
- The price of the spare parts,
- Viessmann’s attitude/interpretation to the application of the guarantee (seem to have a reputation of trying to blame installers and not honouring it)
