Snake Oil Salesmen?

Just been browsing fleabay and came across this

AIR SOURCE HEAT PUMP OIL GAS BOILER REPLACEMENT 11.9KW | eBay UK

Now I'm not an expert on these but to claim 600% efficiency opened my eyes, until I read the outside temp at this COP is 43oC .
I read further and there's some wild sweeping statements in there!
Now I'm of the mindset that you have to carefully size ASHP's or it could (and most probably will) end up in disaster. The way I read their advert, its only a case of connecting in flow, return and electricity and bingo! away you go!..

I foresee many unhappy customers, which IMHO will end up reflecting badly on heat pumps, all because of people like this who don't appear to have a clue about what they are selling.


Any thoughts?

At 2c its a 7kw ashp what is at -7? a 3kw? This is what gives renewables a bad name

Looks like wharfe plumbing are setting themselves up as the next big joke in heatpumps a bit like the trianco activair, and what a pile of rubbish they were.

​Now that is a great statement to put on your advert ......... looks like something that would come from china?

How do they get the idea that R407c is inferior to R410a? They are similar replacement refrigerants to replace R22.. I smell something... and its not nice..
I only pity the 14 people who have already bought them.

Unguided1 look at this link Buy Activair Air Source Heat Pumps 3kW Online still on sale.

look at the video

What do you think to the controls i.e. the 3port that is used as a bypass? think the heat pump may cycle somewhat

To be fair to Roger who has been producing articles in the plumbing magazines that are free in all plumbers merchants for years I suspect that at the time of him making this video which is quite a few years old now believed the bull that was given to him by trianco.

Having said that why this video is still being used I dont know as in my opinion it should be used as a perfect training tool on how not to install a heatpump for example, no buffer tank, aav fitted externaly, no Y strainer, fitted in conjuction with a perfectly economical gas condensing boiler, as Ian has stated a 3 port motorised valve used as a by pass that if you look at the pipework feeds back into the return of the underfloor heating which could lead to the heapump not only short cycling but also depending on the underfloor controls force the underfloor heating circuit to run backwards.
