Yes, I saw it mentioned on BBC Red Button (hooray, got it right this time - no longer Ceefax!). A sad byproduct of the global warming scare, the rush to renewable energy and unscrupulous business. The same thing happens on a much bigger scale, when local councils give planning permission for the installation of solar farms and wind turbines. But I bet a post-installation analysis and comparison with predictions is never done.

Sadly, there will always be those whose business model is based on deception.
The various firms I approached for quotes for my installation all appeared to play by the rules, and used PVGIS figures for their calculations. The only problems were those who tried to quote for more panels than would actually fit on the roof.
Looking at my spreadsheets, the estimated output calculated forward to current date was 25.11 MWh, and the actual performance has been 31.65 MWh, already having paid back the initial investment.
I gather that the official predictions have since been updated, appearing to be more optimistic. When I have a moment, I may well compare the results.

I think anything that can save usage of power or can, on site mean you get some heating or power directly is all you can hope for, as anything that relies on some external company to play fair is doomed to failure before the end of life of the product. Brian

I suspect the same is going on with air sourced heat pumps for domestic heating and hot water.

No. Of all the green shit I have analysefd a few things made sense.
Ground and to an extent air sourced heat pumps would, if run off nukes, be cheaper than oil and comparable with gas.
More pumped storage would be worth building at a few sites in scotland,
LED bulbs were actually worth having.

It is not clear either that that house was being heated by an air source heat pump (they talkked abiut heat recivery ventilation) or that it was correctly installed. Normally on new builds there is massive insulation, and underfloor heating - you need extremely large areas of 'radiator' to utilise the rather low grade heat from a heat pump.
If that famiy had an inadequate heat pump output or inadequate radiator area so they had to use immersion heating to get te temeperiures up, teh coist will treble. Alreday hot water needs to be boosted to 60C as that is generally outside the limits of an air sourced pump
I repeat. done *properly* heat pumps should be similar in cost to gas.
I nearly put in ground source here but I would have needed far more pipes in the UFH downstairs and it would have been impossible to utilise teh existing upstairs heating at all.

Is this the nuclear electricity too cheap to meter?
Air sourced may only be sensible if you want domestic air conditioning to get a cooler house in summer. However this could mean that an average household will will be using more electricity than currently being consumed. The system becomes much less efficient during the winter months and running costs barely break even compared to gas or oil. Maybe they will short term with the 7 year early adopter subsidy which is not guaranteed if demand exceeds the money allocated. This assumes that you have well insulated house and possibly replace an existing CH system.
Ground sourced can be viable but this costs more and care has to be taken with the design of the installation, as some local councils have found when implemented on some of their estates.
What the greenwash companies are pushing (mis-selling) is retro fitting air sourced heat pumps to existing CH systems that are unlikely to to have the savings claimed over other sources of heating, more so after the subsidies end.
When the Greens come to power in the next general election we will end up with more wind turbines and solar panel farms which will need to supply a lot more electricity to power all of our CH and electric cars as conventional fuels will be banned after 2025 in our zero carbon society. No domestic gas or oil and with more expensive electricity and then air sourced heat pumps fitted to your home will become cost effective.

all those abandoned deep coal mines were so hot the miners worked in shorts and tee shirts, so I'm surprised they haven't been re-used as a ground-source district heating system.

Ha. They got my non technical sister to sign up for solar panels... on a North South aligned double pitch roof.
They repaid her deposit when I got her to cancel!

ROFLMAO!
My exes late dad bought some water heating panels on thee basis they would 'halve the cost of heating'.
When I pointed out to him that the brochure said 'halve the cost of heating his hot water' and never mentioned the house heating at all, he refused to believe me.
