Can add a lot of extra length, as heat loss is proportional to length, may be better to use angles if you can. Possible affect flow rate though.

And half an hour on the interweb to get typical figures.

Oak has an SHC of 2 kJ/kg.K Ceramics are around 0.8 kJ/kg.K Oak has a specific density of around 750 kg/m3 Ceramic around 2300 kg/m3 So pretty similar once thickness is taken into account. The conductivity of oak 0.17 W/m.K Ceramic 1.5 W/m.K If you know the thickness of each, you can easily work out the real difference. Be better to say that wood does not conduct heat like ceramic tiles do.

Have you checked your installer is on the MCS database? Did you pay a lot for the installation? Did they show you an estimated annual yield for what you have paid for?

70°C. My car can do 113MPH. Dreadful fuel consumption at that speed. Cheaper to buy a bigger cylinder.

What wall U-Value are you trying to achieve, and what ACH are you after? I am with @SimonD, just make sure you have enough roof overhang and fitting downpipes is not too much of a problem.

Not at all as far as I know. You can work it out from the NG delivery data and the installed capacity. You could also look at the Triads system and see how frequently they had to disconnect large users, or just at the price on the ELEXON portal. Capacity and price are not the same thing, nor is Capacity and security of supply. Going to be interesting to se how they balance it this winter (assuming it is a very cold one), not sure how our EU gas supply partners will be to part with it. I am all for a 3 days working week again. Actually, no I am not, what I tend to do in the winter anyway.

Was 1970s, well before we had below minimum wage Polish builder, so probably child labour, rather than a man. Make Britain Great again, employ 8 years olds.

Yes, 80%+ of my electrical energy usage is at night, which I am quite happy with. I would be more than happy to buy in a neighbours PV power at say 18p/kWh when I want it, not so sure they would be willing to sell it to me at that price when they would be buying it in for me at 28p/kWh.

My parents bought a new build when we moved back to the UK in 1975. Roof banged so loudly I was convinced someone was up there. It stopped after a couple of winters.

My parents had a complete new system fitted by BG, cost them about £8k. Turned out it was not leaking, just a faulty tester. They use a nice young man now, must get him in to do a service.

Sounds a lot, about a tenner a house. Or 4 cups of coffee a year, or a packet of fags. When you go to a restaurant, do you ever consider that you are probably getting £1.20 worth of food, the other £13.80 is for everything else. Have you found a better source of data than the OFGEM spreadsheet I posted up?

Right, fair enough. Sounds a bit like my Combination oven, I am sure it can do a lot more than I use it for.

PV diverter with a meter on it maybe?

Does that not contradict the whole ethos of an air fryer?

More than my EDF E7 standard variable rate, quarterly billing then. So a bunch of crooks misleading the uneducated, figures.

I only looked at <=4 kWp systems, not sure how much of a difference that makes. I wonder where they got the 800k (ish) number from. I am going to get you started, is the Go EV charging rate lower than Outgoing? I still wonder how Octopus have such cheap rates, where are they buying from, and what are they paying. There seems to be such a mismatch in what has been happening to wholesale prices and what they are charging.

Where is the fun in that, I have procrastinated, debated and put off doing stuff for decades.

It does as it reduces the temperature difference. If you can add insulation to the floor, do so, but it is not an easy retrofit. Getting rid of draught (or is it drafts) helps a great deal. Though if your place was built in the 1940s, should be all solid walls.

Does it slow down the traffic light GP start? I usually pull away at tick over, even on a normal hill. 1 in 10s are a bit different, then 1200 revs maybe. I wish I still had autos, they are so much easier, seems strange when I drove in town I had autos, and London is pretty flat, now I am in the land of extinct volcanoes, I have a manual.

Welcome. Will be interesting to see the difference in building methods and standards. (I got a speeding ticket in Austria, never paid it, did not have enough shillings left, it was a while back)

All my neighbours are on drugs, except the Romanians, they are alright.

I think our @Ed Davies, your neighbour (ish), had some made up locally.

As mentioned earlier, the FiT was to encourage business growth in the sector, not to subsidise individuals earning/utility bills, the latter was an unseen consequence, like roof 'to rent' was. Prior to the FiTs there were some grants, our @DamonHD had some fitted under the scheme I think. Many, pre FiT, early adopters would have been happy with net metering, i.e. sell at same price as you buy. This, on the face of it seems reasonable, but at the time, the lack of smart meters made it impractical. What should really have happened is that the FiTs should have been at a much lower rate, and not tax free earnings. If the rate had been about 12 to 15p/kWh, index linked, people would not be having this debate now. There is also a problem in that the current high prices have a specific cause, which has rippled though the economy, take away the cause i.e. Putin, and prices will get back to normal. This creates the problem on what to do now, but I would not be trying to set up an independent trading system to trade in home grown energy. if such a system did exist, and paid say 30p/kWh, I would plug a diesel generator in and milk it for all it is worth. What the Spanish did.

How does that work, does it slip the clutch or use a combination of brakes and semi-automatic clutch engagement.
