For the majority of the general public in the UK, heat pumps represent a big change. Despite the fact the technology's been around for quite a while, they feel like something "new-fangled", and generally speaking people don't like change. The Cosy 6 looks different even to the eyes of people who're already used to living with a heat pump, so there's a huge amount of subjective evaluation going on and that's entirely natural.

So in taking a look at this video and the product it's discussing, we've an awful lot of unknowns centring around two basic questions:

• How well does it work? All the technicalities and objective data to understand how effectively it performs its primary task
• Could I live with it? All the subjective questions around aesthetics, perceived acoustics, acceptability to home occupants and close neighbours, judgements about sustainability of manufacture and operation and so forth.

Human nature being what it is, plenty of people's interpretations of the objective data will be biased by their subjective opinions - not everyone, of course, but many and often without realising it. That's why, I think, @wreckguru's review will be particularly well received here since the insights will help cut through preconceptions and uncover more important questions to ask at the same time.

That's not an attempt to put you under pressure, btw @wreckguru; we're still only looking forward to a plain honest summary of your installation as you see it. However, I suspect it'll be devoured rather more readily and by far more people than anything I could write about my (yet another) Ecodan.

Plastic is a wonderful material used in the right products. I believe that I’ve read that plastic buckets have saved countless lives in Africa and other developing countries since they allow water to be carried cleanly. Plastic is easily sterilised using bleach for example whereas metal or sodden buckets can’t be. It’s just single use plastic for trivial items (plastic straws, carrier bags etc) which are not recycled which gives it a poor image environmentally. 

I’m not sure what percentage of steel is made by green processes rather than the traditional coking coal and I can’t find the right reference. This article says 70% by the established process which emits large levels of carbon https://foresightmedia.com/historie/swp229602-ae7KOqYq-e7d68  

But if a product looks ugly it often doesn’t catch on unless it becomes very fashionable. I couldn’t believe Crocs (an ugly plastic sandal) were worn by the beautiful people with designer dresses until I saw it.

This is a better article to understand the carbon cost of steel https://www.sustainabilitybynumbers.com/p/green-steel-goodall?utm_source=publication-search  

@lucia how do I start the article?  I see there is a list of articles but no "create" or + button for me (I might be looking in the wrong place!).

The simplest, @wreckguru, is to write the article as a separate document and pass it on to @editor. That way he and you can discuss the most appropriate home for it, which might be wider than just the forum itself.

gotcha, ta.

I will do that - it won't be ready until my snags are done - which allegedly is tomorrow!

Not a problem, @wreckguru, and no need to rush other than plenty of people here eager to hear your experiences.

If you want some ideas on how others have written their articles, take a look at ASHPs – Renewable Heating Hub. I have no doubt yours will be a very welcome addition to the library.

That is beyond belief. It’s looks like he has put a council bin outside his house! Neighbours must be fuming. 

@marvinator80 It could also be confused with a utility company’s connections cabinet! But as mentioned before, an open invitation for… ahem… waste material. (Ours is safely tucked ‘round the back’ M’lud) Toodles.

@marvinator80 the fanboi's sighting is a bit odd, but I doubt his neighbours care.  It will likely be full of fag ends and plastic by spring.  Mine in in the back garden.  My pipe run is also shorter - from pump to diverter it's about 16" rather than 16m, lol.

@wreckguru In one of his presentations where he is considering the siting of his pump, he dismisses his back garden completely as this would clutter the space and he needs the whole garden space for his offspring to play!😵‍💫 Regards, Toodles.

Given that’s an exit vent, not an intake, that could end up with some hugely amusing results.
