Electric heating systems, where to start?!

So in conclusion folks, taking a punt on air source heat pumps is a safe bet if you run 'a fairly large construction company' and can supervise and control the choice of equipment and the labour doing the installation. Otherwise you're in the lap of the gods.

Don't bother reading peer-reviewed reports of trials conducted scientifically under controlled conditions - that's just history!

Also, some people who run 'fairly large construction companies' are very strong promoters of air source heat pumps. Wonder why? Perhaps it's really lucrative business?

I don't in anyway install any renewables, I've looked and it's not that profitable only 30-40% profit margins.

Anyway, the point I am making is renewables including heat pumps are the way forward and are the cheapest option in the long run.

This market has not been regulated until very recently, this means all peer reviewed reports are on installations from an unregulated market place which is no longer the case.

You are taking these reports as gospel, rather than looking at them in context which does not apply to today circumstances.

Your consernes are about the installation not the technology it self, so your advice should be to choose a good installer not don't have one.

You clearly have no personal experience of heat pumps in the uk, and are quoting trials from poorly installed heat pumps.

You are clearly not in and building trade, I run a fairly large construction company and no manufacturer will allow you to touch their product until they have given you training and approval. This includes, insulation, rendering products, pipework literally everything! So yes manufactures do care because it is their product and their reputation on the line.

Yes an installer would turn down a job if a house is unsuitable as they would get a bad reputation and not get any work, do you know how a business works? Lol. Clearly an employed drone....

My recommendation is to spend a little more money initially but save thousands in the long run.

Th fact is, you are applying historical standards of installations to todays standards of installations and consumer protection and what you are saying has no relevance to anything that applies today.

It would appear that reading, and understanding the content, is not your strong suite.

May I remind that this is what Robwitz posted and you confidently can state is wrong.

There's a huge amount of evidence that retrofitting air/water heat pumps to older houses doesn't deliver the claimed benefits. (Cardew is right on this).

Please note – the word ‘retrofitting’! Although it seems irrelevant to you that the OP is considering retrofitting a heating system.

It is also apparent that you haven’t bothered reading, or getting one of your employees to read, either of the EST 12 month trials of heat pumps.

All time and expense the heat pump manufacturers spent on modifying heat pump installations in the trial was apparently nugatory effort. They should have known that every system was poorly installed and it was a mistake by all these manufacturers to even let any of these installers ‘touch their product before they had training and approval’.

So anyone researching retrofitting of heat pumps should ignore the Energy Saving Trust trials and rely on your input. Have you published any of your results?

They DO achieve the claimed benefits of the claims are accurate, this is obvious.

If someone makes an unrealistic claim they are misspelling, simple as that.

Can you not understand English with a few typos? Or has it got to the stage where your argument comes down to grammar... Lol

I genuinely cannot understand your post.

Perhaps someone else can enlighten me.

Sorry, I haven't a clue.

You do understand you are just being difficult and pretensions grammar Nazi

Or just frustrated because you know I'm right

My brain hurts!!!
You can retrofit a geothermal type heating system, but you do need to know what you are doing. We have installed many, due to the lpg costs here in Italy.
The problems that I have seen,from many of the UK installation postings, is that the system is underpowered to cope with the heating demand. This also seems to be the case with new installations as well.
You always need a good and established installer, not Joe Bloggs the plumber who went on a one day course and now knows everything.
I have a 84 year old guy who had a retrofit about 5 years ago and is as happy as Larry that he is saving over Euro 3000 per year against his lpg bills.
The EST trials, showed the failings and inexperience of many of the installers, which is a good thing.
