So I might just make an almighty stink on the net that Vaillant 7kw units are noisy and see how that goes

If that makes you feel happier then go ahead, but it won't fix the problem!  

If you are convinced that its the heat pump that is at fault, then the risk if you call Vaillant out is small, so surely worth taking in relation to the overall cost of the job.

@jamespa I’ve had similar issues with things over the years and found that manufacturers will more often than not stick there head in the sand while blaming everyone else.

That's just human nature unfortunately, not special to heat pumps, manufacturers or any other subset of people involved in any particular joint enterprise more it less whatever it is.

That's why personally I favour trying to work out what the problem is and, if possible, fix it.  Holding people to account is of course always part of this, but not at the expense of fixing a problem if it matters significantly to me. 

Of course that's just my approach, others are quite at liberty to take a completely different approach.

Agreed, but when you spend a substantial amount of money on a system, expecting it to be fit for purpose and is not. Someone IS accountable, regardless how silly the reason may be. Consumer contracts and all that... otherwise we will all be in the wild wild west and might as well go and string the installers by their toes in the public square.

I don't want to take over this post, but had done a SAR request to my installers, and they came back requesting more time, however this part of the e-mail is quite interesting:

It’s a shame, reading back through some of the correspondence, how we’ve ended up in this situation. That said, it goes without saying that I will do my best to work with you and provide what you have requested within the revised time frame.

I also want to acknowledge that both myself and the wider team have read the articles and online reviews you’ve posted. To be completely candid, this was disheartening for us to see. We work hard to help and keep our customers happy, and we don’t feel the article paints a true picture of the project. In fact, there are some inaccuracies in it. That said, we are where we are, and our focus is on moving forward and resolving matters constructively.

I replied and kept it very civil, asking them what exactly have they done when I raised multiple issues with the system over many months? It is quite clear why we ended in this situation:(. I really wish we didn't had to as all they had to do, was listen to the customer.

The devil in me almost warms to that in some cases, but I do agree its not how things should be done.  Contracts and consumer protection law definitely have real value and please dont take anything I say as suggesting otherwise.  I certainly rely on them from time to time.  That said, if I can fix it myself (without undue expense in time or money or voiding warranty) I generally will, just because its quicker and easier so saves my limited 'fighting energy' for the battles that matter most.

The response to your SAR is interesting to say the least.  As you say all they had to do is listen.  

The problem I’ve found over the years is the consumer law in the UK isn’t fit for purpose and requires potential small claims court action. I’ve known companies to have several complaints against them to trading standards and still not be shut down and or investigated.

another example is in Australia they have robust laws regarding cars which essentially cover them for years past the 3 year warranty. In the EU they have 2 year warranty on all consumer products, we do not and the reason given by the government was that our consumer law provides longer than 2 years, yeah you try that next time your in Curry’s.

@adamk

Will not even get started... The power of the law is easily overrated. If you can reach a human, common sense can go a long way.  

I am with @jamespa, whatever I can help fix I do. But sometimes you give a hand and before you realise your arm is gone!

That's the problem with the UK, in comparison with America for example or Germany. However, as long as the owner/consumer keeps all the information and can build a timeline of the events, especially if they get a welcome pack that states projected SCOP etc. Then it is still the law. You just have to be prepared to fight for it, and ALWAYS pay at least the deposit on a credit card. The other options are small claims court and house legal cover insurance (if under the maximum sum allowed) or via solicitors. Either way, if you can get a report and a few quotes, regardless if you pay for them, you should be able to claim everything back.

Credit Card or Loan would be the easiest way and keep the installation under £20k if possible. Main difference with these options is that if you go to a lender, they will pay you back and then chase up the installers initiating a legal dispute (which you don't have to worry about). If you end up in court, then you have to retrieve the money from the installers. They could shut down the company if enough claims are being made, but even if they do, as long as you lodge the owned amount, you become a debtor and should have first dibs at repayment. Still no guarantee that you get your money back.

on a facebook thread someone has comented to the effect that there is a fix for the noisy 7kw.

I’ve done everything I could to optimise my setup short of balancing my rads, which to be honest even with all the trvs and lockshields open seems to work well and all rooms upto temp, yet I’m getting 4 cop for hot water and 3.3 for heating.

im on wc 0.45 curve 15c min flow senso is set to active 20c, cleaned the strainer, as that was limiting my flow to 725l/h now getting 1100l/h, yet now it’s 3.1 cop. Is it just because this time of year it’s cycling more?

here’s a pic from the app.

You should be getting better than that at this time of year even though it will be cycling, unless it's really cycling a lot (short cycling).  Can you help by answering some questions?

1. Are your trvs fully open so rads on constantly?
2. Have you got any room stats operating?
3. What size heat pump and house loss
4. I presume no buffer or llh?
5. 6kWh heating delivered is nothing, over what time period was that (default is 24hrs)  
6. Under 'Status' 'main system' on app how many hours has it been running for and how many on/off cycles?
7. Whats the floor area and construction of your house?

Based on the info you have already provided there is a possible cause, but if you answer the above it should confirm or otherwise.
