  1. Not sure I understand that. Is your plumber/designer saying an ASHP don't produce much at night? And, just to be pedantic. Your chosen heat pumps/MVHR will have a power output in kW, not kWh (or Kwh, kwh, kW/h, KWH). If you have an A2WHP and UFH, just get a buffer plumbed in, it will save grief.
  2. That is OK, hardly goes below that down here.
  3. Thank you.
  4. Was thinking about putting one in my shed.
  5. Have a ferret around, if it is a large, fat one, with some nobble ends, it may well be.
  6. How noisy are they, and do they chuck out warmed air, and how warm is that air.
  7. Ask again, they may have put the cabling in.
  8. They way I understood it, (a decade since I left the industry now) it is a combination of local usage, local generation and main 'large' generation. The 16A limit was put in place as it was a relative safe amount to deal with. Trouble is, because the original FiTs was so generous, and system prices halved in 18 months, more systems where fitted than anticipated. This caused a few problems (down here local grids were soon saturated, even though the main bulk carrier cabling is underused by many MW). I seem to also remember that CHP was limited to 8A, as it could produce that all day long, all year long, but would usually kick in early morning i.e. 5 to 6 AM, when it was of little use as the electricity morning peak is later. Why did you not get 3 phase? As you like wiring, why don't you make an off grid system to run some low powered stuff i.e. lighting and IT. Easy enough to have that switch a mains BMS on if they get too low on energy. You can also dump to thermal storage, even if it is just a couple of storage heaters in the dungeon, if overheating happens, just wear less clothing.
  9. I still think that, with special permission from the DNO i.e under G98, it is the generation capacity that is measured. So if you have a batter system that can deliver more that 16A to the grid, you are stuffed, and if you have a PV system as well, you are double stuffed. You could be sneaky and keep adding more capacity with micro inverters. Probably hard for them to detect that easily.
  10. 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.
  11. Don't cylinders have a thermal cut out at 65⁰C now. The one at work does, and think mine, at home does as well.
  12. 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.
  13. Or just copy and paste the in.
  14. 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.
  15. 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
  16. Ideal you want the airtightness to include the insulation. Would rather defeat the object of it if air can pass through it.
  17. Started in France, took a while to get over here. We still have it down in PZ, considered modern and flash I suspect.
  18. Late Art Deco, 1901-1913 ?
  19. If your house is that leaky, no need to put the MVHR in.
  20. 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.
  21. 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.
  22. If you have one blade that is intact, find a GRP company and see if they can copy it.
  23. 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.
  24. Culture and better weather. And the language is easier to understand.
  25. Don’t know what you mean Diction is your dick in motion.
