Not sure I agree with that. Set by people with a different agenda maybe.

Interesting the idea that school failures ended up in the trades. Education does not stop the day you leave school. There is a difference between wanting to learn something news, and not wanting to. There are also many reasons people fail at school, most of them are not educational: it is really a reflection of our poorly managed public education system and a legacy of our old class system. There is also a big difference between educating and training. If your 12 year old daughter is given sex education lessons at school, you probably thing that is a good thing How would you feel if she was given sex training instead?

We all love a virtue signaller.

Just a quick reality check on CO2e emissions. Since 2020 the UKs emissions have hardly ever gone above 300g/kWh.

Has anyone actually check how much power a CAT5/6 cable can carry? Probably a lot more that 5W. Oh, lots more. https://en.wikipedia.org/wiki/Power_over_Ethernet

Have you got anything you can cover the decking with? Sheet of ply, or even an old duvet or two.

Not what I was getting at. A small part of the body may be at a reasonably comfortable surface temperature, the rest may be well below. Usually when the body is under stress, it starts to shut down non vital elements to conserve energy i.e. numbness. If the small warm part tricks the body into thinking all is well, when it isn't, there may be unknown effects. Probably not a problem in the UK, but maybe in other places in the world. As I said, not my area of science, so I may be talking bollocks, but I have never been happy with the often quoted correlation between direct electrical heating and dry air causing medical problems. The fundamental physics does not back it up, and data seems to be lacking in this area.

@JamesPa Can get a conclusion down to about 300 words, then send it off to BBC Radio 4's You and Yours. Nearly every week they are talking about HPs, most of it is accurate, but often misguided. Pointing out that there are planning restrictions may spur some action. I wonder how a car is allowed to be parked outside the front of a house with our planning laws.

I wonder if that is a physiological effect. It may be a case that warmth only needs to be felt on a small part of the body and the whole body reacts as if it is warm i.e. starts perspiring, increased blood flow, hair standing on end. Physiology is not my area of science at all. Like most of the medical sciences, there is so much variation between studies that it seems to invalidate itself very quickly.

That is an interesting observation. Was an environmental monitoring done. We hear a lot about how 'electric' heating makes the air dry. Very rare to see data that backs it up. If I remember, I shall try and take some pictures of the thermometer and hygrometer I have at work.

Don't think I could walk very far afterwards. Ah, Michael Jackson, can make my eyes water reminiscing, and my hole weak. Blowing Bubbles was a step to far for me.

It is, C for coulomb, named after Charles-Augustin de Coulomb. It is the SI unit for electrical charge.

Ah, see what you mean. But surely it is the English Way to draw an arbitrary line and then get it enforced. There is an old joke about the Indian neighbour's chicken laying an egg in the Englishman's back garden.

He maybe, via a roundabout route, using recycled materials.

It does raise an interesting point about the hardware. Take may house, very small heating load, a 4 kW ASHP is way to large, but that is probably the smallest there is. So as I mentioned earlier, at the lower end of the scale, there are limitations that cannot be overcome easily. Very large buffers/thermal stores are the only real solution, but not an easy sell to someone with a small house.

Turds are tapered to stop your bumhole closing with a bang. Sounds like a doctor is needed more than a noise.

C is a coulomb. C = A.s Or 6.241509×1018 e With e being the charge of a proton. There are a lot of protons in a battery.

You are starting to sound like a statistician

Lots of assumption there. The premise seems to be that the system is badly designed. Without looking at the source data it is hard to tell what is really going on.

Isn't this just showing the effectiveness of the BMS and thermal management? Probably find that the batteries could accept a much higher charge, but then degradation becomes a problem. The main point I was trying (badly) to make is that you probably have to oversize the storage so that it can accept the capacity you need, safely, in the relatively short time you have to charge up.

Yes, reality is a killer.

That chart is not showing time though.

Your right, no housing crisis down here at all. I still think that the majority of the houses in that study will be larger than average and more under occupied. And even if they are not, the goodness of fit is still reasonable for a very poor bit of descriptive statistical presentation.

Charging of batteries, and thermal stores for that matter, is not linear. So it may take 60 or 90A initially, but the power will decay exponentially as the batteries get closer to the maximum charge. Thermal management may help a little, but that will use some of the available power.
