So sorry to hear that.  If there is anything more we can help with please do summarise the remaining issues.

@jamespa Thank you sir the help and talking on here was definitely helpful much appreciated 👏 Sadly they way things are it seems customers have a raw deal of it sometimes if it all goes wrong

@burtis, I’ve followed this thread pretty much from the beginning and what an exhausting way for it to end.

I think @JamesPa is right… if there’s anything we can still help with, keep throwing it at us. But the bit that really sticks with me is that after nearly three years of complaints, inspections, emails, technical reviews and supposed remedial work, you’ve ended up paying another installer to sort the system anyway. That doesn’t feel like a complaints process delivering an outcome and it feels like you simply outlasted your willingness to keep fighting it.

And I don’t blame you. There comes a point where getting your heating sorted and getting your life back is worth more than another six months of emails.

One thing I would do before AE Renewables changes anything is ask them to document what they find. Nothing overly elaborate. Photos, a short summary of what they believe is wrong and what they intend to change. Not because I’m suggesting you launch another battle, but once they start correcting things, some of the evidence of the original installation disappears.

I also think Gas Worx refusing to service a system they installed deserves to be recorded here. Whatever the rights and wrongs of the wider dispute, abandoning the aftercare relationship doesn’t exactly inspire confidence.

And, for what it’s worth, this thread hasn’t been pointless. Quite the opposite. You’ve documented the buffer, noise, flow problems, debris, pump and flow switch saga, warranty discussions and the complaints process in great detail. It’s become a pretty sobering case study of what happens when an installation is basically functional but riddled with issues and nobody seems capable of taking ownership of the whole thing. 

Please keep the thread going when AE get involved. I’d genuinely like to see what they find, what they change and, hopefully, the post where you finally say “It’s sorted.”

@editor 

I completely forgot to document what they said was wrong hahah too excited to get it sorted 😂

So they went through the system some small issues mainly with pipe routing, lagging, debris and dirt in the system and small efficiency issues. 

What got changed...

-Had another flush out

-removed glycol

-anti freeze valve fitted

-manual air bleed valves instead of the auto ones

-re pipped the buffer into a volumiser and relocated to a more out of the way location

-removed circulation pump

-put a concrete base in and put the unit on anti vibration mounts

-Re lagged exteral pipes to a better standard and also removed multiple 90⁰ bends 

-moved a kitchen radiator to a less obstructive, more sensible place

-changed a bit of restrictive plastic pipe to copper (still have a bit of plastic left but its in a stud wall)

Not had a single error since 🤘

Was running a bit hard still but have since changed Homley to run as "radiators as underfloor' setting to allow it to run a lower flow temps as a test. (As i have installer access.) Been holding the temp and flow rate is good. Runnings costs today are lower than yesterday with a COP of 5.5

All looking well 👌 

@burtis  Thanks for posting this and Im so pleased you are now making progress.  It sounds like a package of changes have been made which together should make a significant difference, and early indications are that they have.  The irony of it all is that none of this is difficult.  The 'problem' lies with some outdated industry practices and poor attention to detail which is easy to identify and, indeed, to avoid in the first place, yet somehow, sadly, it doesn't happen.

Please do keep us updated with your experiences and of course if you have any further questions feel free to ask.
