  1. That can be insulated the same as any other area, energy transfer is agnostic on direction. She should have thought about all this before, what they are meant to do. Why on this forum, many of are very sceptical of architects.
  2. All you hear tbh is water flow Women testing flow, mid stream, is something to worry about.
  3. How noisy is your home already. May be worth finding out, you may be worrying unnecessarily about it. My experience of Paris is that it is noisy. Now I know you are not in the centre (the last place I stayed was in Rue Beautreillis, Jim Morrison fame), so not the busiest place, but noisy.
  4. I think in really it does not work anywhere. There is a disproportionate I crease I energy usage when there is a change in temperature. Bit like driving. You will soon notice the change in MPG if you only accelerate hard, when going up a hill.
  5. Glad you have some acknowledgement that there is a problem. Really does highlight the need for half decent energy monitoring. Especially if there is 3 Phase. 3 Phase is not really that useful in the domestic setting, except it does allow for a greater capacity. Reducing the loads though time shifting i.e don't run a 6 kW water heater at the same time as charging the car and cooking supper, is probably an easier and much cheaper option.
  6. Well it is 700 J/s which is enough to cool 0.56 of a kilogram of air by 1⁰C every second. So 20m³ would cool by 1⁰C in 36 seconds. I think. I hate doing arithmetic without a spreadsheet.
  7. Anecdotally is an partial anagram of No Data. Without knowing the energy inputs, air leakage and temperature variation, it is not possible to compare the two. Building Regs will tell you a minimum standard anyway, so you cannot go below that. If you know the power losses and the power inputs, the sized of the room, you can calculate the energy needed to heat it
  8. No, the air temperature. If it drops below the dew point, condensation will form, so you end up with a damp, cold garage. And a rusty bicyclette. https://en.wikipedia.org/wiki/Dew_point
  9. Does it not just make it a self fulfilling prophesy though. There are many products on the market that are all three. Just take mass manufactured food, or automobiles. White goods are another, a basic fridge, £120, lasts for years, does the job asked of it, and as it is a 'white good' looks like most of the rest. Planning, organisation and execution are they keys to getting a job done properly and within budget.
  10. I am sure that some will claim that because they live in a rural setting and they use 'their own wood', this story is untrue. Smoking in public buildings was banned, and that was less of a problem than this.
  11. Should have built a fence around it. https://metro.co.uk/2023/02/01/couple-at-war-with-neighbours-over-fence-blocking-front-door-18200458/
  12. Two things. Will the temperature drop go below the dewpoint, this will cause condensation. And It is maths, not math.
  13. Makes a change from fish fingers.
  14. Totally missed the point I was making.
  15. Saw your car in that local. Reg is. pEN 1s
  16. https://www.ebay.co.uk/itm/252376922299 Was popular in the 1970s
  17. or bS (expletive deleted)
  18. Eat more fruit.
  19. Standard Error of the Mean. Allows you to infer how accurate the results are within pre agreed limits. When looking at something like PV output and Solar Power, there is no need to work at the 1W level, 50 W bins would be accurate enough. Would be the same as a P-Value of 0.05.
  20. Just add in the standard error and it will be close enough.
  21. Almost Kayaks to Lord Weinstock country residence.
  22. Could be a problem for any material. There are flexible polyester resins, and with a suitable orientated weave, expansion joints could be made. I am willing to work as your consultant about all stuff GRP.
  23. That is because of the testing methodology, they have have been tested for output with an input of 1000W.m-2, at 25°C, which would be the point that they deliver at least the stated output. They may well have produced 10% more for during the test. Modules that just fail the STC would be relabelled to a lower output i.e. failed at 330 Wp, relabel as 310 Wp. Even of they are just 1 Wp below the level. So the trick is to not buy the highest output modules, but the ones below, if there is a decent enough price difference. If you find a local weather station that has a W.m-2 sensor on it (kWh/day is no use here), you can take a random selection of dates, but pick the same 3 times each day i.e. 10 AM, 2 PM and 4PM, then correlate the output of your system to the irradiation levels, then see how the performance has changed over the years. You can even adjust for different ambient temperature.
  24. While filling the bath, the shower pump seemed starved of water. Shut the taps, bathed, got up in loft and the cold tank is not refilling. Shut off water, removed ballcock and valve. The little white plastic cone that has a hole in the middle has a small screw in it. The same screw I dropped down a pipe when changing the cylinder a few years ago. Ten minutes, problem sorted.

  25. That is 87% of the stated peak power output of the module at standard testing, which is not the same as as what they actually tested at when new. That makes it very possible that over a decade you will see a quite large drop off in performance of the total system.
