Around the amount I use for everything except DHW and Space Heating.

And they stopped using the ITC, which was just a cartel designed to keep the supply of tin under control and the price high. Also, river delta dredging became profitable as the technology improved. Cornwall also did not invest in modern mining methods, assuming the hard rock mining was the only viable technique. I think Chile led the way in mining during the late 80's and 90's. South Crofty (our last working tin mine) was on TV the other night, saying that it is going to reopen. Been hearing that all the time I have lived here.

Or substation. Keeping with the car theme, how about Kona, and just hope no one from Portugal sees it.

Around 17.5% of the installed prices. So assuming a mean installed price of £7,000, and around 1 million installs, that will be £1.225bn. So not far out.

And the government, under Cameron, response was 'The Big Lunch'. There were more people looking at big waves in Porthleven than at the Big Lunch, says it all.

But it has enabled 2.7 GWp of domestic (up to 4 kW) installed capacity in the last 10 years. That is out of a total of 12.95 GWp. That compares favourably with our nuclear program, which has installed nothing new and is only going to add a couple of GWp. So if one used the 1 MWh generation for each 1 kWp installed, all PV now generates ~13 TWh/year Hinkley could produce about 16.6 TWh/year at 95% of full capacity. There is about 950,000 sub 4 kW in the UK, so if the premium was £1,500, that is ~£1.425 bn. I cannot find a figure for how much Hinkley has cost so far, but i will guess it is more than the MCS premium.

Food, in real terms, is a lot cheaper calorie for calorie, but we now tend to eat out a lot more, so household spend is similar.

I am dubious of this sort of tank. We have well understood about the properties of heat for a couple of hundred years now. If this was a brilliant solution, we would all have them. And anyway, my 200 quid E7 tank has 2 immersion heaters, one in the bottom, one in the top.

Really down to the cost of different technologies/solutions. You may find that overall, a simple water cylinder heated directly with an immersion heater is cheapest. There may be slightly higher thermal losses, but these can be reduced with strategically placed insulation. Air2Air heating may be worth considering if you fit an 'oversized' MVHR system. Not quite as messy as digging up a floor to add insulation and UFH.

It is really down to sizing a system for your consumption. I could, if I had room, fit a 4 kWp system and configure it to export nothing. It would mean being very wasteful in the summer, and still importing in the winter.

I shall convert that to 28 kWh/day, which is around 1.16 kW. If your CoP is around 3, then that is 3.5 kW of thermal energy. With your floor area, that is ~30W/m2 Now considering you have bungalow (detached I assume), you have a lot of wall and roof area. I use around 9W/m2 to heat my small terraced house, but if it was just one storey, I suspect that the energy use per square meter would double (I don't have heating upstairs). And if I was detached, I would be adding an extra 200% of external wall area, so that would probably bring it close to your usage.

There is a saying that political parties loose elections, not win them. Now I may be in the minority here, but I have not seen much in the last 10 years to give the general public confidence in their chosen decisions. Just to put a decade into perspective, that is the difference between puberty and a degree qualified teacher starting out on their first job, Tesla going from a niche development company to the leaders in EVs, Facebook gong from 400 million users to 2 billion. And about the same amount of time that most people on here take from deciding to build a house and getting it 90% finished.

Um

Chris Grayling is a treasure and shows that keeping a minister in place can pay dividends. When I say dividends, what I mean is that he takes the pressure off everyone else to do anything meaningful. Is there a similar chart for top civil servants, the people that do the real work.

How old are these 3 boys? A tend to agree about keeping a sleeping area separate from cooking. Have you thought about heating?

There have been instances recently where the opposite is true.

Anyone wish to comment on @Nickfromwales's comment about a thin slabs needed higher temperatures for longer to counteract thermal instability. Just does not ring true to me.

When I was first at university, I had a flat made that tried to peel his skin off with a potato peeler. Was down to some bad acid. We just told him to stop. A while later, he drank too much and had to have a trip to hospital for a bit of pumping. Found out a few years back that he decided to jump of a cliff in Dorset. All very sad and looking back, all the signs of serious mental health issues were there, but were were less enlightened 40 years ago.

Basing rent on a fraction of income is an odd way to look at it. Be painful if everything was based like that. Basing rent on market value of a property is also a bit strange. You can get two very similar houses, in the same town for quite different money. The town I work in is supposed to be posh, so I looked at the LR database to see what 3 bed houses sold for (was a few years ago and prompted by an estate agent talking bollocks). 4 houses sold for around £220k. One sold for £5m. So could I rent the £5m one for a third of my wage?

All my socks are the same. In fact, most if my clothes are. I hit a winning style formula in 1978, so stuck with it. Apart from the platforms, but they say you shrink with age. I keep wondering how much energy I save by not wearing knickers. Discus that if you want.

There was a TV programme in the 80s called Monkey. There was a Dutch priest who frequently gave young village girls a blessing. Turned out he was a German Nazi officer on the run. Don't suppose they make kids programs like that anymore.

I agree, but will point out that my Tax Free Allowance was £800/year and income tax was 33% on the rest when I started working. And I seem to remember my sister having to put some cash aside for a retrospective emergency tax payment in about 1978. And we had 10% new car tax on vehicles until 1990. Fags and booze, in real terms, cost he same, except now supermarkets sell beer cheaper, and food is much cheaper now (why people eat out so often). Free higher education was limited to about 10% of the general population, not because of ability, but just university/polytechnic/HE places. And the grants were not that great, think I got £1200/year.

I agree. Link that in with minimum wage with more part time/seasonal/minimum hours working and you have around 40% or the working population not paying any income tax at all, and many working families claiming benefits. Minimum wage, which benefited many people 20 years ago, has now depressed wages for the middle classes. I went for a technical graduate job a few years ago, when it got around to talking about money, I pointed out that it was the same as a MacDonald's shift supervisor. And we got ours (priorities) right when we were their age of course. Hindsight, experience. Thats what BH is about innit? I was a complete twat when a teenager, still am. Over my working life, there has always been schemes to increase employment in deprived areas. Not many seem to work. The few that do seem, on the face of it, successful, are the ones where large nationalised industries closed down and foreign firms were asked to move in i.e. Nissan, Toyota, Honda, Siemens, Sony. On a more general note regarding price, is how the workplace has changed. When I bought my first place in 1981, multiple of earnings was 3 times main income, 1/2 times second income. This is now 4 or 5 times joint, or household, income. So for no extra property, or better quality, you can borrow more to buy it. Now I am not saying that women should be chained to the kitchen sink, quite the opposite, but when banks have those sorts of multiples, prices will rise.

That seems to be the ticket. May get a couple to play with. I considered this for another project, bit costly, even secondhand. I like cheap.

To me that says that the delivery temperature is too high i.e. delivering too much energy in too short a space of time.
