Exactly, about time the public learnt this. We, as a nation don't trust government much, but are willing to part with cash to a salesman, while knowing nothing about a product.

In the same way a Tesla on Autopilot will slam the brakes on when when it sees a speed restriction sign on the back of a truck.

That is a valid point, we are going down the EV route and home charging will be expected to happen.

Ask Google. AI is not very good. https://www.google.com/amp/s/www.newscientist.com/article/2282240-ais-dont-understand-simple-physics-like-a-ball-rolling-down-a-hill/amp/

There are science philosophers that may disagree, but I don't agree with them. 32 years after his death, Paul Feyerabend's ghost is still haunting us.

It is mainly the over complicated and expensive BSI/Eurocodes system employed.

As most houses 'settle' over time, does the parge, render or plastering crack, leading to the airtightness diminishing? I have often wondered this but most people are reluctant to spend money to get a second air test done. This may lead to a false premise that any heating system is under performing, when in reality, it is a house leaking more.

What particular problems and why not in badly insulated houses? Take two houses that have the same heat load i.e 30 kW @ -5⁰C. Will a correctly sized ASHP under perform just because it is an ASHP, compared to a gas boiler? Does it even know it is an ASHP? Does a gas boiler know it will perform better because people on internet forums say it will? Design it right.

We have discussed to death the merits and drawbacks of different heating systems. The one thing that keeps cropping up is the lack of justified, and verifiable, design. Trouble is, no one is willing to pay for it, so what do people expect.

Change the word glue to advanced polymer adhesive and it sounds ok. As @markc says, depends on the glue and the size and quality of the mating parts.

I got a scaffold tower, and can do heights. £2000 of your English pounds. Will bring own tools.

Wire brush and a lick of paint will make it fine. Easy from a scaffold tower.

True for all buildings. And just about everything else that is made. There are more Fords in the world than BMWs.

One of the universities I lectured at got a load of laptops (was a fair few years back). They build a lovely wheeled cabinet to store them in, with wiring to recharge them. First time they got recharged, about 25 of them, in an airtight box, the temperature got so hot that they all got damaged.

Looks a Rachman rental. My insulation got disturbed and ended up sitting over the vent in the soffit. Sucked in wind drive rain, then wet the plasterboard below. So may be a problem, get it fixed. And a lick of paint on the window would not go a miss.

Get a battery vacuum cleaner. This is not a facetious comment, we are heading that way, not many of us use mains powered tools these days.

Worth pointing out that there are a number of different 'timber frame' systems, with timber frame being just one of them. A bit more detail here, but not a definitive list: https://www.bre.co.uk/filelibrary/accreditation/rdsap9_91/BRE_RdSAP_Manual_5_-_Identifying_basic_constructions_v8_0.pdf https://www.trada.co.uk/start-here/timber-frame-construction/

That is brilliant, I have eventually understood, a bit, how this hedging works. So it is either sell it, or use it, depending on the price paid and the current price.

Me to as I have been working on a similar project recently.

Except the grid is getting cleaner all the time. Often below 100g/kWh these days. The last year we have full numbers for is 2019 and overall carbon dioxide emissions were 210g/kWh. Gas boilers are around 200g/kWh. Gas boilers are not going to get any more efficient, and most don't get close to the laboratory maximum. So I shall stand by my statement that electricity is the way forward and will be a major contributor to reducing emissions. We are not electrifying for no scientific reasons at all.

It is a Youth Centre, you have to be on a special register to go there, not on the other special register. Got that Abba dilemma again.

It is also to do with emissions, not just price. National Grid sets the price for bulk transport, and a lot of the larger, local infrastructure. So rural areas, or places like Cornwall have higher costs.

Was chatting to someone that owned a commercial laundry. To cut their energy bill they used a combination of heat pumps and ozone injection. Not sure if that is viable on the small scale, but an interesting idea.

Distribution prices. These variable prices, like some green taxes, did not apply to small operators.
