  1. Not sure how it is calculated, probably in BS 7671 somewhere. Reason it is 13A is so that a 3 kW load, like a kettle, can be used for a short time. Most 3 kW domestic stuff is usually 2.8 kW, which is 12.2A. So a little safety margin built in. I also suspect that if you tried to start a loaded 3 kW motor, the fuse would blow.
  2. Don't cylinders have a thermal cut out at 65⁰C now. The one at work does, and think mine, at home does as well.
  3. A 13A plug can only take a continuous 10A load. A wire has a resistance. The longer the wire, the larger the resistance. As wire heats up, the resistance increases (basically how a heater works). So fatter and shorter wires are best.
  4. Or just copy and paste the in.
  5. Economic Theory. From WIkipedia Gordon's triangle model[edit] Robert J. Gordon of Northwestern University has analyzed the Phillips curve to produce what he calls the triangle model, in which the actual inflation rate is determined by the sum of demand pull or short-term Phillips curve inflation, cost push or supply shocks, and built-in inflation. The last reflects inflationary expectations and the price/wage spiral. Supply shocks and changes in built-in inflation are the main factors shifting the short-run Phillips curve and changing the trade-off. In this theory, it is not only inflationary expectations that can cause stagflation. For example, the steep climb of oil prices during the 1970s could have this result. Changes in built-in inflation follow the partial-adjustment logic behind most theories of the NAIRU: Low unemployment encourages high inflation, as with the simple Phillips curve. But if unemployment stays low and inflation stays high for a long time, as in the late 1960s in the U.S., both inflationary expectations and the price/wage spiral accelerate. This shifts the short-run Phillips curve upward and rightward, so that more inflation is seen at any given unemployment rate. (This is with shift B in the diagram.) High unemployment encourages low inflation, again as with a simple Phillips curve. But if unemployment stays high and inflation stays low for a long time, as in the early 1980s in the U.S., both inflationary expectations and the price/wage spiral slow. This shifts the short-run Phillips curve downward and leftward, so that less inflation is seen at each unemployment rate. In between these two lies the NAIRU, where the Phillips curve does not have any inherent tendency to shift, so that the inflation rate is stable. However, there seems to be a range in the middle between "high" and "low" where built-in inflation stays stable. The ends of this "non-accelerating inflation range of unemployment rates" change over time.
  6. The Daily Mail will like it as it is going to save us all. https://www.dailymail.co.uk/sciencetech/article-10410911/Geology-Earths-interior-cooling-faster-expected-study-suggests.html
  7. Ideal you want the airtightness to include the insulation. Would rather defeat the object of it if air can pass through it.
  8. Started in France, took a while to get over here. We still have it down in PZ, considered modern and flash I suspect.
  9. Late Art Deco, 1901-1913 ?
  10. If your house is that leaky, no need to put the MVHR in.
  11. Ooh er, can’t remember and my house docs have disappeared, was fairly good, I seem to remember that it was around 1.5, which pissed you off as you wanted under 1. But there were the few leaks around a couple of windows, and where the air intake came in for your wood burner (a very good reason to not have one, just another large hole to fill up). You filled the holes where the cables and pipes came in at the time, but don't think they were that bad. Can't remember if you adjusted the kitchen to conservatory door, think you did.
  12. They would probably have to make a simple, single sided mould, but should be able to modify the mountings. May not perform quite as well, but would be a relatively easy job. The small Proven WT had plywood vanes.
  13. If you have one blade that is intact, find a GRP company and see if they can copy it.
  14. Much of that depends on the size of the property. The smaller the internal space, the easier it is to do. Trouble is, small places have limited roof area for PV. So what you have to do it have a wide, but narrow place with a very large roof that is south facing, and at the most effective angle for winter generation i.e. quite steep. You will not get away with a septic tank these days, so you will need a treatment plant. This uses electricity, around 1 to 2 kWh a day.
  15. Culture and better weather. And the language is easier to understand.
  16. Don’t know what you mean Diction is your dick in motion.
  17. I usually have a good long term memory, but when I went over to see him, he had just put the SA in and the old Combination was still in the spare bedroom. I know he did some strange stuff with plate heat exchangers to preheat water and recharge the SA. There has been some confusion (certainly in my mind) about what a thermal store actually is. Seems the term sometimes gets used incorrectly.
  18. https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/1043383/table_224.xlsx Try that.
  19. I think this is the data, can't view it easily on the phone. https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/1043383/table_224.xlsx
  20. Think that is what I have. I hate it, and now, after 35 years, it is failing. I want to clad the place, but council have put me in a Heritage Area, so I am (expletive deleted)ed.
  21. Don't think he ever had a TS. He had one if those combination cylinders with the F&E built in on top.
  22. Same down my way. Odd really as there are two huge connections for the old Hayle power station. Meant to be a nuclear plant there but we are too radioactive.
  23. Bad luck, but you might get cheaper power.
  24. @ProDave is in Scotland, they frequently have a surplus of power.
  25. Probably a lower fraction of the population than you would find in an architect's office.
