Can you soften it with a blow torch. Or put some mix in a barrel and light a fire under it. Pour into hole, put a metal, or even timber, plate over it, then drive over it a few times. Rinse and repeat till level. (Road making materials are, by mass, the world's biggest recycled materials)

So bathed in warming microwaves. Non of us are far from a military base. I used to live and work in High Wycombe, home of HG Air Command. Now I am fairly close to RAF Portreath, and RNAS Culdrose. Would have to cross a 'radiation' zone to get out.

Not on its own, but a few of them on a short circuit scrambling track will sort it out, and you can charge an entrance fee.

Only read your abstract of what you intend to do. Does your incoming mains support this, there will be a drop in flow once all them bends in the pipes and the length of the pipe rums is taken into account. Effectively two different types of heating systems. Not a problem as suck, but needs a bit of careful thought re flow rates, flow temperatures emitter areas and the different heat distribution within a room i.e. where the radiators are located. As I am sure you have read from people that run their HPs efficiently, they are effectively 'on' all the time, so room usage is just a distraction. Treat it as a room that is always at 21°C. (maybe a slight setback at night). Fit as much as you can by all means, the marginal costs difference is minor, and maybe negative. Don't think there will be need for additional wiring, but it does depend on if it is an AC or DC coupled system. Initially get a suitable inverter for your capacity that is acceptable to your DNO i.e. how many amps you can connect per phase. Worry about battery storage when you build the second house, the energy market will have changed (again) by then. You have to fit one, so no point fretting about it. If you put the cabling into conduit, you can fit another cable into it for battery storage (EV charge points are usually in a garage, where batteries may go in the future). Bet that is (expletive deleted)ing noisy, fit quadruple glazing. As an after thought, and replying to this This is why some of us have to do the right thing, we cannot rely on others. It also stops them having to know anything.

I don't understand the 2012 pricing. 2012 was when we held the Olympics. And a good TV series about it.

I think you are misunderstanding the whole concept of 'new generation'. If you accept that we need to replace, and run, extra electrical capacity, which also includes the associated infrastructure, and it is also agreed that the price is fixed until some future date i.e. 20 years. Then wind and solar are coming in as the cheapest. To put it into automotive terms, it is like buying a car. A new Ford Focus is between £24,200 and £33,770, on a finance deal, with Ford's BIK, the monthly price is between £140.48 and £343.84 (https://www.ford.co.uk/content/dam/guxeu/uk/documents/price-list/cars/PL-New_Focus.pdf) Buy a second hand Focus, over ten years old, and the prices vary from £360 to £3, 984 (AutoTrader). No good comparing two very prices. even if the product seems the same, while arguing that they are the same.

I think so. Works out cheaper than new gas.

Did you include landscaping in your plans, think you can get the VAT back. Sounds like you need to remove topsoil, sieve the weeds out, then respread. Maybe start with grass seed.

I am fine, but thank you.

Had a bit of a traumatic day today, so not really kept up with the news, but the results of the power supply auctions were released today. 8.4 GW of wind. https://www.gov.uk/government/news/record-breaking-auction-for-offshore-wind-secured-to-take-back-control-of-britains-energy

So is living in a tin shed, animal skin tent, igloo ect. Have lived in a Queen Anne period place, that was misery, but it may have b cause it was my last school.

There is around 120 GWh of battery storage approved for the National Grid. I do not know many domestic, or very small scale systems are connected, but suspect that it is a small fraction of that. So when it comes to 'smoothing the grid', which will affect wholesale prices, the Big Boys are already on it. So spend your money carefully and size any battery system to take best advantage of your own PV production. Or treat it as a hobby, it is probably a cheaper one than most.

The Copenhagen model allows for it to be both on and off, simultaneously. The room temperature will only be revealed when it is measured.

Lay what you can, then fill where the missing ones go with some concrete. Then cover in cheap vinyl flooring.

Huh? Down here in the rocky far west.

Not that extreme down here. Are the windows taped in with proper adhesive tape or similar?

20 kWh.day-1 is quite a lot. I use about 1.5 kWh.day-1 during peak times. Can you reduce that usage significantly, or get PV to come ntribute more to it. What was it before? This is the problem with ToU tariffs, they can change them all too easily making any capital expenditure redundant.

Graphite has a k-value of around 200 W.m-1.K-1

Quite a good thought. As it is a new discovery, maybe someone will work out the optimum trunk radius to timber mass, which should help identify the best species to plant and at the ideal density, for different regions. Would also be interesting how it affect other types of plant bark/skin. Totally unrelated, but maybe not, I noticed that the main types of trees that got blown down last night were conifers, which are not indigenous to this area at all. In fact, trees are not indigenous.

Thankfully they are not submerged too often. What I found interesting is the surface area they cover. A good reason to not put them in a wood burner. Though it does raise questions about using timber in general.

From this weeks comic. Tree bark microbiome has important overlooked role in climate Tree bark has a total surface area similar to all of the land area on Earth. It is home to a wide range of microbial species unknown to science, and they can either take up or emit gases that have a warming effect on the climate By James Woodford 8 January 2026 Melaleuca wetland forests in New South Wales, Australia, are hotspots for tree microbial life Luke Jeffrey / Southern Cross University The bark of a single tree can be home to trillions of bacteria, and these microbes may have an important but neglected role in controlling greenhouse gases in Earth’s atmosphere. The total surface area of tree bark on the planet is thought to be around 143 million square kilometres, nearly as much as the world’s total land surface area. This surface makes up an immense microbial habitat known as the caulosphere, but the microbes that live there have received little attention from scientists. “In a way it’s so obvious, but we have always overlooked tree bark,” says Bob Leung at Monash University in Melbourne, Australia. “We never thought of microbes on tree bark, but it makes sense, because bacteria are everywhere, and if we can find microbes in soils, on tree leaves, then most likely there will be microbes on bark.” Leung and his colleagues began by studying a wetland species commonly known as paperbark (Melaleuca quinquenervia). They found that there were more than 6 trillion bacteria living in or on each square metre of bark, comparable to the volumes found in soil. Genetic analysis of 114 of these bacteria showed that they mostly came from three bacterial families – Acidobacteriaceae, Mycobacteriaceae and Acetobacteraceae – but all of the species were completely unknown to science. Remarkably, these microbes have one thing in common: they can use hydrogen, carbon monoxide and methane as fuel to survive. Hydrogen (H2) isn’t itself a greenhouse gas, but through reactions with other molecules it can increase the warming effect of methane in the atmosphere. The researchers then looked at the bark of another seven Australian tree species from a range of habitats, including casuarinas, gum trees and banksias, measuring, both in the field and in lab conditions, whether the bark of the different species absorbed or emitted greenhouse gases. They found that all barks consumed hydrogen, carbon monoxide and methane in aerobic conditions when oxygen is available. But when trees are submerged in water and oxygen is limited, such as in swamps, bark microbes switched to producing the same gases. The canopy of Melaleuca quinquenervia trees in an Australian forest Luke Jeffrey / Southern Cross University The team estimates that the total amount of hydrogen absorbed by bark microbes globally is between 0.6 and 1.6 billion kilograms each year, representing as much as 2 per cent of the total atmospheric hydrogen removed. This is the first time scientists have attempted to assess the contribution of tree bark to atmospheric hydrogen, says team member Luke Jeffrey at Southern Cross University in Lismore, Australia. “Discovering the hidden role of trees doing more than just capturing carbon dioxide in their wood is very important,” says Jeffrey. “They are active cyclers in other greenhouse gases. This is exciting, because H2 affects the lifetime of methane in our atmosphere, therefore H2 consumption in bark may help in reducing our growing methane problem.” However, the global picture is highly uncertain, as the team has only sampled eight tree species from eastern Australia. “A lot of work now needs to be done across various forest types, tree species, microbial communities and site conditions,” says Jeffrey. Brett Summerell at the Botanic Gardens of Sydney says the study highlights how little we know about the composition, diversity, abundance and role of microorganisms in bark. “How this might vary across a broader range of tree species, particularly in drier climates such as savannahs and woodlands, is interesting,” says Summerell. It will also be important to understand the interactions between fungi and bacteria in bark, he adds. Journal reference: Science DOI: 10.1126/science.adu2182

Regardless of all the above, a good SSR does not make that horrible click/thump/buss that a contactor can. More specifically on safety, and as @ProDave mentioned, two contractors in series. Our sunbeds used contactors and they welded up on a regular basis (about 7 kW inductive loads). We initially rewired to have duel contacting, then changed over to SSRs. Newer solid state controllers came along and took the problem away in the early 1990s.

Half a cubic metre per hour per square metre of exposed area is considered quite good. Has anyone managed that without filling the house up with glue? Seem to remember that someone got a 0.23 m3.h-1.m-2.
