  1. @OwenF , ceiling mounted solution: no. I redesigned the kitchen and have moved the hob off the island, which makes an extractor much easier to design. I will be building it within the next 6-months. If I had kept it on the island, I would have chosen a downdraft extractor, albeit I think they are flawed in terms of effectiveness given that hot gases rise and fast.
  2. MVHR: ensure the intake and exhaust are on the same face of the building so they are exposed to even wind pressure.
  3. Can you find a similar door or window which is PAS24 and is similar, provide that certificate to your building control officer while explaining that your manufacturer no longer exists. I had an issue with a window being larger than the size that was PAS 24 certified by the manufacturer, and so in the strictest sense lacked PAS 24 compliance. I provided a copy of the PAS 24 certificate for the assessed size and explained the situation. My local-council's building control then said it was fine.
  4. Timely post for me. Reinforces my idea to double-up the heating in my place under construction; am at first fix. I have wet UFH and am planning to install electric-mat UFH too on my two bathrooms, probably under LVT flooring.
  5. I have screw piles and was advised when doing mine that this form of piling (as it does not remove any soil as such) did not trigger the Party Wall Act. My piles produced almost no vibration so it sounds like yours are not screw piles. And if yours are not then there is a good chance (as described by others above) that the type of pile that your neighbour is using may well fall under the Party Wall Act. In which case you would have plenty of powers to respond.
  6. @HughF, that's interesting. Do you know the approximate volume of your system? Mine will be about 95 litres. It will be a similar open-loop system to the ones in this thread.
  7. Yes, rather concerning. The "Mira Flight" tray comes in a few different forms. I was intending to buy this version below. But am now unsure. Such poor basic quality control is rather damning.

  8. … and cooling. Often summer cooling is a greater challenge for a passive house than winter heating.
  9. My guess is that… You should pay VAT on the hardcore that you buy but only if you're buying from a VAT-registered entity. You would then claim it back at the end of the build if you qualify for the "DIY Housebuilders’ scheme". The crusher man is correct in charge you 0% VAT on his services (including his machine, which he operates) as that counts as site labour. … only a guess.
  10. I have a mono-bloc so no F-gas certification needed. I might guess without evidence that the majority of domestic installs are mono-blocs. If you want a career in heat pumps, is F-gas certification really needed. Could the Heat-Geeks course, or similar, be a better route in to the industry. Utterly ignorant so I could be missing the mark. Just my tuppence worth.
  11. Back in 2022, I was charged by Latzel €20.83 on a £500 order so sounds plausible.
  12. Thanks @nod. Makes sense. Very helpful. Thanks all!
  13. Thanks @TonyT. Good to hear. My decision has also been helped by when I saw the price difference for "full-pallet-only" specials compared to the lines held in-stock. Nothing dampens my perfectionism more than being asked to pay a *lot* extra to achieve it
  14. Thanks @nod. Good idea I will try that. If that fails, I have some t-bar at the ready. 3m height without a join would have been nicer but I guess a join isn't the end of the world. With top joins, I assume its best to avoid any four-way cross-style joints and aim for t-joints such that the fill-in board at the top over sails the board-to-board joint beneath.
  15. I need about 19x boards of 3m acoustic plasterboard (3m x 1.2m x 15mm), e.g. Gyproc Soundbloc, Duraline, Knauf Soundshield Plus, or Siniat dB board, etc. Any will do. Of course, all the suppliers near me (Cambridge) only want to sell me a full pallet of 36 boards. Does anyone know of a supplier anywhere who will split a pallet of 3m acoustic boards?
