The thing that infuriates me about my ASHPump. This is a warning to all considering them.
It comes with a **hydraulic unit, a suitcase sized unit that sits in the hardware 'chain' between 1. cylinder & the 2. outside large fan unit (all will be aware of what 1 & 2 look like).
This **unit, is an absolute fkn nightmare, & I'll explain why. Ok the cylinder in most houses, is in an upstairs spare bedroom. So the ASHP will include a new cylinder, similar sized. Fine. But this additional **unit has to be close to the cylinder. I had a cupboard in the spare room, so it was fitted in here, fine it seemed/ a good fit too.
Right. This damn unit... once temp drops below 3*C outside... makes overnight mechanical noise, not just incessantly, but so audible that it's heard 3 bedrooms away. 11pm-7am. Awful loud infuriating motor noise. It has meant my sleep is disturbed (3 bedrooms away, let alone the spare bedroom itself, & the next bedroom no.2 along), I am angry, the spare bedroom unuseable, no.2 severely compromised, & my mental health has been RUINED.
NO mention to me by installers of this unit making any noise at all. Vaillant (the appalling manufacturers of this awful design) & me have been in an 18-month BATTLE of stress trying to find a solution. None. I'm stuck with it.
BE WARNED.
