Think it got sold as a residential place rather than a public house. Someone should be able to dig the the planning history. I have a vague memory going there in the 1970s with may Uncle who was from that area. As he would have said 'hard lines that'.

Has all your home automation and security caught it on camera? Have a word with the people that supplied them. They will know who has had it away, and where they went to.

I thought glyphosate worked by being transported from the foliage to the root. Low concentrations of it work well with Japanese knotweed.

I was pondering thro the wall heat pumps as an alternative. The would suit terraced houses very well. So I looked up how many terraced houses there are in the UK. 6.9 million. 10% of that would hit the government target of 600k heat pumps installed annually. If a typical terraced place needed 4 if them fitted, say £2k (should be possible if greed does not get in the way) and primary energy usage is halved. At today's natural gas prices of 6.894p/kWh ($2.58/therm) and electricity price of 3.5p/kWh (wholesale prices as I type this, they will be different when I post this) it makes sense to change. Even at a realist retail price of 10p/kWh for gas (once boiler efficiency is accounted for) and electricity at 35p/kWh (about what the price cap is), it still makes sense on running costs (assistant me SCoP of 4). There is an argument to be had about government incentives, but that is not really the point. The point is to get these units manufactured and installed where they can be fitted easily.

Were we not complaining about high gas prices for twenty years though. We need to treat the causes of high heating prices rather than treat the symptoms.

Possibly because of the temperature differences. Take the South of France, not unusual to se 35°C. Take the inside temperature way, say 22°C, that is 13K difference. In the UK, during the heating season, that would be an outside temperature of 9°C. There could possibly be defrost cycles when heating.

I had the same with a statistics exam, sat there feeling like an abandoned 5 year old at primary school. Amazed everyone how I completely flunked it.

As a thought experiment, why don't we collectively design one. I wonder what the power of the AC unit in my car is. There are millions of them about.

Oddly, I found it pretty simple and basic, very mechanical in nature. But most physics is mechanical. Maybe there needs to be some new SI units that take into account opinion and bullshit.

Yes you do keep saying this. The same argument is used by the anti-EV lobby as well. How fast do you want this change, and how much are you will to contribute to it. Are you willing to help stop some of the perpetual myths about renewable energy. What societal changes are you willing to put up to reach these goals. The 'renewables' industry is not a single pressure group, it is many dispersed groups ranging from individuals spouting their hobby horses i.e. me and Chris Packham, farmers, local councils, to government departments i.e. Department of Energy and Climate Change. They all have different motivations and aims. Why I keep to the same story that combustion technology is a bad thing and using less primary energy is a good thing. As for renewables being built, it is happening quite fast, could be faster with a clean up of planning laws and stopping this pandering to local opposition groups. Environmental stewardship is not about standing still or changing nothing, it is about, using the best evidence available to improving the environment into the future. Just yesterday, on the Radio, here and here, highlights the problems nicely, it highlights that a lot of people genuinely believe that the problems of renewable energy delivery is either insurmountable, or too expensive, or relies on some magic storage, or a tidal barrage between Devon and Wales. What gets my goat about the whole climate change/ energy debate is the polarisation. Wind Turbines get heavily criticised because the old blades get sent to landfill (which is only partly true), PV gets criticised because of the 'toxic chemicals' used in manufacturing. It is as if the no other manufacturing industry has these problems, farming is the worlds largest polluter, should we all stop eating? What really needs to happen is that we have to accept that to improve the environment i.e. less pollution of all sorts has to happen. Then let the engineers, technicians and scientists find good ways to sole the problems, then the politicians, pressure groups and individuals have to sell it to the public. Sell is the important part as it implies a price. Just what price people will accept.

Right, quite correctly, 'Heat' is energy.

They coincide with the 'heat' plots. What are the heat plots actually measuring? When dealing with thermodynamics, nothing is a straight line, even if it looks like it sometimes. Using my very favourite equation ekt, it is only when k is set to 0, or infinity, that you get a strait line.

Really comes down to combustion technology is a bad thing. How different the world would be if electricity was the primary energy source and not carbon//hydrocarbon energy. There was this in my comic this week about timber, not all is rosy there, but we knew that. Comes down to two thing, resource management and what is measured. Building things with wood may not be as climate-friendly as thought Wood is a versatile construction material that could be used to replace carbon-intensive steel and concrete in construction, however the emissions involved may have been underestimated By James Dinneen 25 July 2023 Wood can be turned into sturdy replacements for steel and concrete Shutterstock/Kletr Using more wood for construction has been touted as a lower-emissions alternative to carbon-intensive steel and concrete but it may not be as carbon friendly as thought. “It would be very convenient if wood were a better solution,” says Tim Searchinger at Princeton University. Wood is, in theory, a renewable resource and any wood used in buildings acts as long-term carbon storage. The advent of sturdy engineered-wood products like cross-laminated timber has also made it more versatile. Past research has found using wood for construction instead of concrete and steel can reduce emissions. But Searchinger says many of these studies are based on the false premise that harvesting wood is carbon neutral. “Only a small percentage of the wood gets into a timber product, and a fraction of that gets into a timber product that can replace concrete and steel in a building,” he says. Efficiencies vary in different countries, but significant amounts of a harvested tree are left to decompose, used in short-lived products like paper or burned for energy, all of which generate emissions. Many of those emissions may eventually be returned if forests are replanted or they grow elsewhere. But Searchinger says that won’t fly when we need CO2 out of the atmosphere now. “Over a long enough period of time you get a greenhouse gas reduction,” he says. “But in the interim you’ve increased warming.” Searchinger and his colleagues modelled how using more wood for construction would affect emissions between 2010 and 2050, accounting for the emissions from harvesting the wood. They considered different types of forests and how different fractions of wood going towards construction would change the calculus. They also factored in the emissions savings from replacing concrete and steel. In some scenarios – such as in fast-growing plantations in Brazil – the researchers found significant emissions reductions. But each of those cases required what they considered an unrealistic portion of the wood going towards construction, as well as rapid growth only seen in warmer places. Growing more trees might help, but they found land for such plantations isn’t available, and clearing existing forests would make the problem worse.

Accounting for emissions in this way, the researchers report in a related paper that increasing forest harvests between 2010 and 2050 would add emissions equivalent to roughly 10 per cent of total annual emissions.

MDF can be a bit tricky, some seems to glue up easily, other stuff seems to not glue up at all. PVA is usually pretty good. PU adhesives can work well on most substrates.

Say you are a supplier.

Thanks.

Shall see if the local library can get a copy.

Can you say, in general terms, what it covers?

Welcome. The only annoying thing about UFH is lack of insulation under it.

Can get an 'evergreen' F-Gas course here, about a grand. https://fgasregister.com/f-gas-training/ There is new legislation about the right to repair coming in. https://www.bbc.co.uk/news/business-56340077 The biggest issue, as usual in the UK, is planning law and implementation. You can forget all the rest, until that is sorted, it will be impossible to install ASHPs in too many locations. The Government has a target of 600k/year, but last year we installed 60k, bet most were on new developments.

Google's Sketchup can show shadows and sunlight hours and rainfall data can be got from the Met Office. PVGIS can show direct beam and diffused daylight, and the associated power. Half the time it is dark.

Like my bedroom then.

Yes it does look like chopped strand mat.
