    It is pennies difference. My Bosch uses between 30 litres and 110 litres, with temperatures ranging from between 30°C and 60°C. It can also take up to 9 kg of load. So taking the worse case, cottons at 60°C, max load of 9kg, the manual says it uses 1.75 kWh. So even at my day rate, that is about 61p. As I usually run it at night, it is 25p. On the mixed load 40°C setting, which can take up to 4 kg, it uses 0.64 kWh. So either 23p or 9p. I usually use the 'speed perfect' setting at 30°C and I seem to remember that it uses 0.3 kWh. So 11p or 4p. So really, washing machines are pretty good. The big saving is is not using a tumble dryer. I am on my second Poundland washing line (I still have some left from the second one I bought), so that has cost be 10p/year. Just thought that at about £8/m3 for water and waste, the small, 30 litre wash costs 24p. Have I ever mentioned that we have the most expensive water in the country, which will also make it one of the most expensive in the world.

    That will be 3,628,800 Factorials are used a lot in statistics. Spot on. This makes the choice of, number of, fitting of bolt important. Bolts are not screws. Though screws could be designed to be used here. Railway lines have to be tightened and loosened for seasonal temperature variations. This has come about as they don't have joints every few tens of meters.

    Does this shed any light on it? https://www.newbuildinspections.com/wp-content/uploads/2024/07/NHBC-Standards-2024-4-2-Building-Near-Trees.pdf

    A daily wallow is my luxury. Along with driving, coffees out and general time wasting.

    Yes. One of the things that worries me about ICEs running on hydrogen. I am not sure what compression ratio they run best at, or what combustion temperatures are, but go too high and NOX's become problematic, and from a health perspective, it is a lot faster than climate change. Quick search and found this. https://www1.eere.energy.gov/hydrogenandfuelcells/tech_validation/pdfs/fcm03r0.pdf May have to read it later.

    The government is about to dish out £600m on training. Personally I think the training needs to go to decision makers i.e company owners. That is where the real problems are. A youngster is not going to convince their time served boss that they are wankers who are not willing to change work practices.

    They dis day that it was oversized for the application. As FIAT (Fix It And Try) made the unit, not a surprise that it never caught on. I still think that CHP units are a good idea for off grid applications. If run on LPG, which is probably the only real option for off grid, then the CO2 emissions are not too bad on a fuel volume basis. But not so great when looking at emissions per MJ. But that does show that running on regular diesel or gasolene is not much worse. Once thermal losses are taken into account, and assuming the thermal and electrical elements is used directly i.e. not running an HP or stored in batteries. The emissions will be about 470 g.kWh-1 which is pretty dreadful, so not an environmental solution.

    Last year, I was the other way around. 80% of my usage is DHW. 2184 kWh. Either I was very cold, or you don't wash enough.

    Thought Ladies of Lavender was more your thing (I am looking at Mick's Mound ATM). If you dig deep into Channel 4 archives you will find me. If the Salt Path was not such a crap story, I would illegal download it, but preferred Gillian in the X Files.

    Just popped into the shop, some junky twat offend me 500 quid to drive him to Bristol. Stop sending your love inbred offspring down here, cost me the coach fair to send him back to you.

    You got to the electronic door lock yet?

    "Cars are going to be smaller in the year 2000" I remember watching this, I still have a thing for Valerie Singleton. Could have been the rumours about her.

    I am always dubious of products claims, but we have started using the below. Got the tape, left over from COVID, off the floor when all else had failed.

    Forgot that. But my lower element is horizontal. I am not sure how much difference it will make in practice, when heating, the water becomes quite turbulent. A combination of density and inertia does that.

    @Nickfromwales When a waste pipe is fitted, it is not at too steep and angle, from what I understand, this is to allow the turds and Daily Mail to be washed down the pipe. If that is the correct theory, what is the minimum angle used that works reliably? With a flat roof, I would think that orientation is also important. Most of our rain comes in from the SW, that same SW wind is also of higher speed than others. That could cause water to be blown uphill and away from any drainage. The above is mental musing as I have not looked at this in detail. This is what I am looking at.

    No one told you that it is on a BMW and not an Audi. And the driver is not sitting in the middle.

    This is what happens with my DHW cylinder. It is on E7 and only uses the lower element, but you can see that there is quite a pronounced temperature gradient after switch off (5AM). With a bit of extrapolation/guesswork, you could estimate that there is a 15°C DT below the element. @John Carroll are you hoping to heat less water and once you have drawn of a bit, the element kicks in and extends the life of usable DHW enough for a shower? If so, you are only putting in 2.8 kW which will only give you a small lift in temperature (does depend on shower flow rate).

    I think the m² in m³.h-1.m-2 is exposed area and not floor area. ACH is just a total ventilated volume. I went through Aggie the other evening. News Agent has changed to something posh. And rumour has it the chippy is up for sale again. And The Railway is being run by the Ex Landlord of the Hotel. The Driftwood is still not sold, and the car repair place is now just Mark selling his cars again.

    While some inertia is useful, it has to be remembered that large electrical grids run on a predictive statistical model, not on reactive feedback. There is also the radial design of the network that would have worked against itself. There is only so much extra power that can be injected into a single bulk transmission line. The UK grid is a ring design, which allows for more entry point for distributed generation. This is partly why the European Super Grid is such an important infrastructure project, even of a couple of countries got taken off grid, it would still function. As we transition from centralised generation to distributed generation, and increase our reliance of electricity (however it is generated) to replace fossil fuels (mainly gas heating and transport), we are just going to have to accept that more cables have to be run around the country. The below picture is on my daily drive along the A30 near Hayle, you can see the sandy towans on the left. The power station was closed in the early 70's.

    Stick building, as is brick/block a financially more flexible option.

    So here is the REE report on the disconnect. Seems it was bad management that failed to schedule the combustion plants, which were being paid to help stabilise the grid. https://www.reuters.com/business/energy/investigation-into-spains-april-28-blackout-shows-no-evidence-cyberattack-2025-06-17/

    Generally, if you have to ask the price, you cannot afford it. Is the design set in stone? You could buy the plot you want, then let the others build on the other plots. Keep an eye on who is doing the work i.e. learn from their errors. If it all goes wrong, sell the plot i.e. sell the dream.

    Draw a few pictures. I think I know what you are saying, but not sure. If your cylinder is 53 years old, that betters my old one by 2 decades.
