Does the insulation on my Air-Source Heat pump installation look sufficient?

Hi @Low68 and welcome to the OVO online community,

It’s so great to hear about your newly installed Air-Source Heat Pump (hello shiny forum badge too!⭐).

Sounds like you’ve already found our Heat pump pipe insulation guide (if not check it out here), so I’m wondering if any of our lovely ASHP community members might be able to offer some advice on whether your installation looks up to scratch. @nealmurphy, @hydrosam , @M.isterW - What do you think, judging by the photos above? Something to raise to the installer perhaps? 

Nice to see someone else with a 10m run of pipework!

My thoughts are similar to @hydrosam 

Check the insulation is suitable for external use. I think it should be thicker than what you’ve got. I’d like to see the joints taped up and also have the insulation taken right up to the unit as any bare pipework will mean heat loss.

Also, the cable would be better in conduit for added protection.

Once again, first hand experience of good and bad insulation for their heat pumps makes our members well placed to judge the work done on other sites. 

@Low68 we hope this helps. Are you able to contact your installers easily or are there already site visits planned?

How’s the heat pump running performance wise? 

Were you given some advice and guidance on how it operates and how it’s set up to run day to day? 

Thanks all for sharing helpful content here. 
I did surprise this but on Googling, it might seem that ASHP generation is such that it's far better to maintain the residence temperature pretty constant. Whereas an extra conventional system, like fuel line or stable gasoline system, you switch it on and it heats up instantly - ground sound heat pumps* are better if they don't have to work hard.
