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

AdamK · 2025-03-29T13:05:20Z

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.

UPDATE.

theyve been and sorted the flexis today by moving them so they are vertical, about the only way they could do it without moving the heat pump, so that’s sorted. Also said they will send the sparks to replace the rcd/mcb’s. So hopefully near the end of the pain, well at least until winter when I find out which rads I need to change😀.

Great news

I edited my previous post (probably after you read it) as the Vaillant manual, at least to my reading and in the version I have, actually permits the arrangement you have. However if they are going to sort it anyway that resolves the matter.

I’m back,

well Vaillant called me a week ago at which point I explained I was still waiting for the electrical works to be rectified. They said they would email them. A week later and just over 4 weeks since they visited last no contact from them. I’ve since commented on a vid about a heat pump install stating the heat geek logo doesn’t guarantee a good install. Interestingly heat geek replied asking if I meant they weren’t heat geek. I stated no they are. Then silence. I’ve emailed heat geek to request I talk to someone who replied cause they are saying even though I didn’t go through heat geek they expect there installers to do stuff properly.

👍

@adamk, interesting point. I’ve not focused much on Heat Geek installations because, compared to other schemes and organisations, we haven’t seen real horror stories. Sure, I’ve had a few emails and DMs about issues, but nothing catastrophic.

That said, as the Heat Geek cohort grows, I’ve noticed a problem with their guarantees. It all comes down to how you hire your installer. If you go through their platform, you get the guarantee. If you hire direct, you don’t, you’re on your own with no Heat Geek backing.

I published an article on this last night to make things clearer:
