Help me keep the faith with my air source heat pump installation

i knew when setting out on this road it would be a challenge i just didnt know how much of one it would be. after having many quotes some i couldnt fathom why they were so high i thought id sorted an installer. problem is they are 72miles away so first issue was doing a remote heat loss which has been back and forth several times to get it more or less correct, but still have one room thats 2m2 smaller than what i measured. anyway the next issue was getting the 28mm primaries in before the new kitchen ceiling goes in. they sent a plumber that proceeded to bugger the job up as the wall sleeve kit hadnt been supplied to him. so sent him on his way. was promised the sleeve kit the next day and i said my plumber could fit it to save them sending an engineer. next day no kit. add to this all the mods im having to do to pipe work to maximise efficiency and im seeing why the take up is tiny in the UK. im not naming the company as they are a recommended one and have apparently done good work else where but maybe thats in there local area. i know living in Boston creates its own issues being miles from any proper trades so if someone asked me would i recommend getting a heat pump in my area id have to say no. theres just not enough skilled trades where i live.

@jamespa in eco or NR mode it is pretty silent until i go in the utility room about 4m away from the outside wall the unit is sat near, then i can hear it. if i turn off eco or NR i can hear it over the TV like ive left a sub woofer on.

In the latter case is it all the time or at certain events only.

Vaillant are, according to others, pretty sensitive about their heat pumps being called noisy and have been known to send an engineer out. It might just be worth sending them a recording.

It does sound as if it could be pipework related. I think you mentioned that the pipework vibrates beyond the flexis, which it shouldn't. Is it well fixed to something solid (like brickwork) on the house side of the flexi and before it enters the ceiling void.

4kW peak of solar PV since 2011; EV and a 1930s house which has been partially renovated to improve its efficiency. 7kW Vaillant heat pump.
