  1. Ah okay, yes there was a quiet update on the coil sizes. I think they still list the coil area as 2.7m2 but when you get the new ones, it's at least 3m2. Special order only, but that works fine for me on my jobs.
  2. Yes, I wouldn't have the pir on the outside either. Principles are definitely to have insulation to reduce thermal bridging. In Sweden, for example, it's very common to have a continuous layer each side of the stud walls. You can then use smaller dimensioned stud. I wonder what the cost implications are of this compared to the cost of the 220 studs plus continuous layer?
  3. I like the Grant cylinders, nice to install. They're also very competitive compared to the various others. I'm now gravitating towards these as a standard option.
  4. I think the powers that be were listening to this thread. Just posted on efixx youtube channel:
  5. Plus 1 to the Click Definity range - lots of options. We have the Metal white variant which is coated metal and looks better than plastic but not the stand out that brushed stainless for example. Brushed metal gets a bit messy when you have boys growing up in the house and sticky fingers are applied allover them. The Varilight we bought initially were pretty awful - cheap plastic screwless cover. And their V-com dimmers never programme correctly on LED strip lighting, even though they were recommended by the led lighting manufacturer!
  6. Yep, https://professional-electrician.com/technical/guidance-on-installing-equipment-within-meter-enclosures-niceic/ Whether, as @ProDave says, anyone pays any attention or the CPS takes any action whatsoever is another matter. As a mate of mine once said. If you're not a member of a scheme and you do something stupid, they come down on you like a ton of bricks. If you're a member of a scheme and do something stupid, they wag their finger and kindly ask you not to do it again.
  7. A good few years ago Microsoft was running an underwater study for exactly this reason - don't know where it got to but with the size of some of these centres, it would be a bit of a task to make them water proof. I think the tests they ran used units the size of shipping container. However, the massive scaling approach by AI is just one silly choice - it's the whose is bigger the better thing. It is actually possible to run very fast and efficient AI on extremely small installations, which maybe at some point they'll realise it makes more sense and costs less money.
  8. Here is a bit of any answer for you which mentions single insulated with a separate flexible sheath: https://engx.theiet.org/f/wiring-and-regulations/29131/types-of-cables-acceptable-in-flexible-conduit
  9. In all honestly I'm reluctant to make a definitive statement on that as it's really not my area. I call the electrician I work with! All I know is that you really need cables that are insulated and sheathed then made off correctly into stuffing glands either into a CU or junction box etc. or appliance and that's it's really good practice to run visible and exposed cable, even if it's insulated and sheathed, in trunking (unless it's something like HO7 or armoured and then it can take care of itself, but these also need to be properly made off into wherever they're coming from or going to). And also that you always use grommets into back boxes etc.
  10. You should have seen what I came across recently when installing a heat pump. My electrician (who was the first electrician my customer had ever known to actually check in the meter box even though they'd had a lot of building work and re-wiring done) found that the armoured cable installed during previous extension work going from the meter box through loft and into the CU was undersized for 100A supply. Then he found that the armoured cable hadn't been made off correctly and the tails were single insulated, squeezed against the metal gland. The sparky who had installed it had then taken some spare insulation slit down one side and wrapped it around the single insulated tails to make it look like they were double insulated. Stunningly bad and the customer said the previous electrician apparently had a good local reputation......
  11. I don't think I'd be sticking a wet finger anywhere near that installation 🙄 The whole thing look bl**dy awful.
  12. Some years ago I bought a replacement charger for my macbook air, thinking it was a proper one and after a few months both my boys started complaining that they were getting electric shocks from the aluminium casing. I didn't believe them until I was sat there and got this tingling electrical feeling in my fingers and arms. When I went back to Amazon the seller had been deleted and there was no comeback at the time. I am very very careful about buying anything electrical from that place and some other markeplaces!
  13. If you've got breeze coming from your sockets, it's very likely they punctured the membrane while installing the electrics - it happens a lot because the contractors simply don't understand airtightness.
