Hi on here. This is my 1st post: I was googling a temperature sensor, & came upon this site which looks very good.
Ok I wonder if folks could help. I have a 7 month dreadful central heating problem from a new ashp split (Vaillant arotherm). My problem is simple, but the solution anything but it seems. Ive had 10 engineer visits but problem remains. It is so protracted its got me depressed, sleep deprived, very cold, & unable to use the system. I feel totally up against a whole company, unable to get this simple thing resolved. I am in a desperate situation now not knowing what to do, on my own, my 1st house recently bought you see, no experience with ch system installs.
The issue is overnight noise. Not from the outside unit (fan, compressor) ..no. Only from the indoor 'hydraulic unit'. Suitcase size box near cylinder, both in spare bedroom. It is this.. a very pronounced whirring pump noise, loud enough to wake me 3 bedrooms away, incessant on-off-on-off bursts 2 am to 6 am. So awful I've resorted to turning whole system off before bed in order to sleep & not be woken (& kept awake by it). This means of course, no heating in mornings, exactly when needed, exactly what it was chosen for (logburner for evenings). The spare bedroom is a total write off as use a bedroom due to the general noise of this indoor unit, but, it is the -overnight- noise which is the problem due to time it does it, plus the fact that it goes into extra noisy mode during them. It is more than infuriating. It is an utter disaster, & absolutely impossible to live with.
Ok I know a few things definitely about the noise: it occurs only when outside temp hits 3.5*C & below: screen says 'Heat compressor active' (so the outside fan unit -plus- the problem indoor unit both spring to life, but only one is disruptive): these awful noisy active periods last 10 mins: the silent time between them approx 40 mins: noise is the indoor unit's pump, more specifically engaging at its highest 'rate': it seems to have a few 'gears' ranging from its usual daytime "2nd gear" (just bearable, tho a continual annoying pump whine in the spare room) to a far more prominent "4th gear" high speed mode infuriatingly only heard during these awful overnight 10 minute bursts, prominent enough to be easily heard in every corner of the house (annoying is an understatement: it is prominent enough to wake you rooms away, & infuriatingly audible).
Apologies for length of this post. But I cannot describe the problem with any less description.
It is imo quite simply unfit for purpose, no question, but Vaillant refuse to fix it/ refuse to acknowledge its an issue now/ challenging me on it now/ Im being fobbed off from dept to dept now after so many visits too (let alone massive number of calls, emails). I'm left high & dry, defeated, depressed, angry & very very cold. All I want is for it to do nothing overnight, as Im told by Vaillant themselves it should do: many of them tell me " it shouldn't come on overnight.. it shouldn't be doing that overnight". Im given concrete assurances by the head UK engineer, to me here, twice I asked him for reassurance the boards would solve it/ stop it coming on overnight "yes.. absolutely.. 100%.. it's a software fault & new boards designed to solve it" he says to me. Boards fitted. But 2 months later, temp drops, exactly the same happens again 2.10 am to 6 am, night after night. Not fixed at all.
Thanks so much for reading. SC.
