  1. What is needed is a standard that incorporates the existing standards. Or in other words, an extra standard.
  2. Refrigerant gas compressors, the major component of a heat pump, probably are made in larger numbers than gas boilers. Both our main cars have them, though mine does make some strange noises sometimes.
  3. Artisan cheese is often made with grubs.
  4. With regards to cost, surely we need to look at the unit energy prices. My fridge takes, on average, about 12 W, so 105 kWh a year. The temp difference is about 15K. Surface area about 2.5 m². So each m² is allowing 42 kWh/m² though. At a cost of £100, and so far 6 years trouble free service, that is £6.66/m². Now my house with a wall of U-Value 1.5, and the same ∆T of 15 K, takes about 2 MWh of energy to heat a year, so spreading that over the whole year, and the 100 m² of heat loss area. That works out at 20 kWh/m². So roughly half the performance of my fridge needed. So the price for an ASHP should be somewhere around £3.33/m². £2000 for the unit only, if it lasts 6 years. Seems the price is comparable. (I am sitting in a cafe, so my numbers may be bollocks, lots of 'summer distractions')
  5. Is that because the grub screws on both handles are not tightened down to the shaft?
  6. You need some blocking diodes. Everything s put right with a pocket full of diodes.
  7. Not going to happen it its current form. I can see no justification of having only 200 m between the walls, why not a 1000, 5000?
  8. Because it is on one of the worlds largest oil producing countries.
  9. Does have only half the population density of London, which is a low density city. Good place to go if you are a window cleaner.
  10. How do PV sales people describe how they work. Do they say they create a black hole.
  11. Or PV/T = C Where: P = Pressure V = Volume T = Temperature C = Is Constant Or, a picture
  12. "All models are wrong, some models are useful". Time for this, again.
  13. Just checked my account, seems I am £0.75p in credit. No sign of 400 quid in my account, but new bill is due end of August.
  14. That would be a cooker.
  15. That will be 0.021 Wh then. 0.5 kWh a day. So somewhere between 3.5p and 17p per day. Or £13 to £62 a year.
  16. I did from my big standard 1987 era E7 200lt cylinder. About 20p a day when heated to 65⁰C. Lot less now it is at 45⁰Cish, and I use most of it just after it has reached max T.
  17. I am not allowed to write it anymore. Last one I printed out said. "(expletive deleted) off back upcountry". Did stick it on the door of another restaurant.
  18. Were. Only as good as the last job.
  19. So @pocster's walk on glazing did find a home.
  20. How many miles a day do they travel, 2?
  21. Something that had been happening, since he was a lad
  22. The doggerel was bad, which made him sad.
  23. Seem to effect halve my customers tonight. (expletive deleted)ing morons, can't read off a menu.
