With pretty much all makes, it's very easy to go back to copper or plastic as they sell them everywhere. For example: https://naturalgreenheat.co.uk/product-category/wras-approved-press-fittings/transitions-mlcp-to-copper-pipe/ I've used Tweetop, Maincor, Riifo, Uni-Press, etc. etc. They are all pretty much the same. The only thing you need to be aware of is what press jaws the brand uses. Some are available that can accept both TH and U, some are only TH or U and some brands have their own. So when you invest in a set of jaws, just make sure you use the compatible fittings. I have both U and TH as I had one supplier who was very good with one brand and then seriously let me down one time by supplying a huge coil of 32mm that was damaged in transit because they couldn't be bothered to package it properly and made it a nightmare to return it, so I had to switch to something else with reliable supply. But for me it's useful to have both sets of jaws because I use the stuff on all my installs. With all the systems you have to plan out your job carefully to ensure access. Having a set of angled jaws helps but obviously adds to your setup costs significantly. The advantage with MLCP is you can often bend the pipe to give yourself access, but sometimes you need to use your imagination in tight spaces - e.g. crimp and then thread pipe into place.

Not just the elderly. I went to service a customer's boiler that I had installed and was under a 12 year manufacturer's warranty. Over an Easter weekend the husband was at home alone and the boiler didn't work and instead of contacting the manufacturer or me, he called in an emergency company who charged him £1200 for the pleasure and didn't even specify what parts had been changed. When I inspected the boiler, I couldn't see any evidence of anything having been swapped out from new.

Gus, look at the picture, the condensate pipe is not sealed into the rain water pipe so if there's a buildup in the rain pipe it'll piss out where the condensate pipe is resting in the tee. Whilst it is 'okay' to have a sealed pipe connection into the down pipe, best practise is to install it with an air gap as a just in case measure. I'm kind of a bit bemused. I'm trying to explain the typical set up, not have an argument. It seems a little ridiculous that the conversation even begins to lean towards an internal BH argument when it's fundamentally about helping an op with a poor installation. For the record I'm Gas Safe registered and have, up until January when I moved to exclusively install heat pumps, installed gas boilers for a living. Yes, there's a single discharge pipe that comes from the boiler that combines both, e.g. Viessmann 100-W, and that gets connected to a standard plastic drain pipe that carries it away. To make life easy for the installer, Viessmann also provides a nice bit of flexible pipe to run from the boiler to the pipework to carry this. It is also permissible to plumb in a PRV from the boiler into the condensate pipework using a tundish, providing that the plastic pipe can be shown to handle the required temperatures of discharge water.

The condensate drain doesn't really work like this. The condensate pipework is technically part of the boiler flue, so it has a 75mm condensate seal trap built into the boiler. In the event of freezing the condensate backs up into the the trap, and then into the boiler heat exchanger and triggers an ignition lock out in the boiler. Depending on the manufacturer's instructions, the condensate drain may not require an air gap where it connects into the drain pipe. Unless the system has a UVC, it's unlikely to use a tundish as there will be a blow off pipe for the pressure relief valve. This should be directed to the outside, or a suitable drain. There's a chance the installer here might have installed the prv into this condensate drain pipe in which case it would need a tundish, but I'd wouldn't expect BG to do something like this - usually they drill a whole and stick a 15mm copper pipe through. Only a couple of manufacturers, like Viessmann have a combined prv and condensate drain, which is again unlikely with BG installations. Best thing to do is for @Babybirddog to call Gas Safe to start a complaint, sending over a picture and then ask for an inspector to come and have a look at the whole installation - basically start the call with a nice question about whether it's correct or not. Then contact BG armed with Gas Safe info. With Gas Safe they will only allow the home owner to submit the complaint. The last one I had was when a customer of mine, an elderly lady who was mostly chair and bed bound, asked me to come and service her boiler. When I tested gas operating pressure with the gas fire running it was below the safe minimum for the fire. I asked her when the fire had been installed, and got the full story on a crap installation that included badly laid out coals which meant the gas fire wasn't combusting correctly either. The installer hadn't registered the installation with Gas Safe. I called them but they wouldn't accept my complaint as a Gas Safe registered engineer even though I told them the installation was unsafe. Sadly, whoever did it, didn't! It could have been a sub-contractor too.

Yeah, that's not great. It should be fully insulated and the insulation should go all the way through the wall. Just resting like that isn't good either. I would personally probably have 2 clips - one just after the bend as it exits the wall and the second before it enters the down pipe. Also, wtf were they thinking with the black? Just looks crap. Not very good standard at all and enough to question the rest of the installation, frankly. Get them back to sort it out as it doesn't comply with the regs or with the manufacturer's instructions on condensate drainage for a start. They should know better.

Boring yes, but also essential. The problem is that you might just end up with shite database design that's poorly normalised as I've found that AI is typically lazy when it comes to entity relationship modelling, preferring to chuck stuff in as JSON without much thought instead of distinct columns and rows, and also needs to be told when to properly use one-many & many-to-many relationships. This is because it can't deal with the full context of a development and it has to be fed smaller components and steps. I made the mistake letting it create my DB on its own to begin with and then we had to have words, after which it created a proper entity relationship diagram and model that I could review and approve. Unfortunately because I didn't feed in my DB design in at the start, we're up to something like DB migration 017 (in Postgres but about 11 more on previous DBMS as well as a full DB re-write) which wouldn't have happened if I'd known all this to begin with. At least it will write all the migration scripts, but not without a handful of crashes on deployment. This is kind of why I'm still surprised you haven't had to touch any code at all with your project.

That's what a decent nailer should do, 1st or 2nd fix - just adjust it correctly for use and you'll get a lovely finish with the nails. E.g. I have interior birch cladding fixed with brads, but my extrerior cedar uses round head and used a 1st fix nailer. But it depends on what finish you're after. The round head nails that are traditionally used on cladding will have a nice shiny round head that sits on the surface of the cladding. For these you use a 1st fix 'framing' nailer as mentioned above. If you want hidden fix, or you just want a pin hole visible on the surface, then you use brad nails and for these you need a 2nd fix, brad nailer that is made for the gauge of brad nails you need to use. Difference in diameter is about 0.8mm as brads for cladding will be about 2mm and round head nails about 2.8m diameter. But, when you buy your 2nd fix nailer, just make sure the angle and size of brads is available in the right material for that nailer. So to help us give you proper clear advice, you need to decide on what finish you're after and also let us know what timber you're using as there are some timbers that can be a bit brittle and still need pre-drilling to prevent splitting, in which case you're probably better of hand nailing, however painful that may seem.

Same here, plus Sqlite and Maria DB. Open Heat Loss has been my first project using Postgres and it's great, especially the way cloud hosting providers like Railway support it natively - makes life a breeze. Although for me the only thing has been learning its quirks at the application layer so had a few issues there - but that's just learning any new DBMS.

What fixings are you planning to use? This will guide you more in terms of type of nailer. I presume you want full round head stainless steel nails? In that case you'll want either a coil, 21 degree or 34 degree framing nailer with a no mark tip, not a second fix nailer that uses brads.

'specially in 4k

I need a little more than 4TB. I've currently got 4 x 8TB external drives full, plus 2 x 4TB full, plus 2 x 2TB mini externals full (a third one just failed on me and won't mount any more). I think I've got another 6TB drive floating about too.They all need quite a bit of consolidation as 3 of the drives are backups from previous Macs, the rest are windows. I wanted to put together a proper home NAS, but prices are just scaling so badly for this, I really should have done it 18months ago when I first had the idea. Now I have 3TB on my local machine and only 197gb of storage capacity left. Why the space? I have my fingers in multiple pots and have lots of video stored, some that need to be edited and rendered, but then I end up increasing the space I need to store the rendered content. So, I was planning on at least an extra 10TB at the very minimum, probably more for proper safe backup storage. YSWIM? I was thinking about your project when watching this video by Braxman, maybe not massively interesting for you but maybe others. He has a video on setting up Openclaw locally on an old laptop and since I have an old gaming laptop I've just installed Linux on I wondered whether I should have a play:

Gotta love it. I had a similar thing where it told me that a load of functionality was completely different to what was in the repo. It was so certain, I had to upload the latest deployment to prove my point! And confirm that we had to audit some other stuff it had done, because we weren't sure what it had implemented. One reason why small steps closely supervised is a good thing. Every time I let my boundaries down, off it trots in some random direction. And I'm only just starting to play with local access! Yes, the M3 is an incredible package right now. I wonder how long that'll last! I wasn't seriously considering the PC, personally I'm just shocked at the recent inflation as I've run out of storage space and was floored by how much it costs now. I'm putting a hold on my plans to remove everything from the cloud and store locally.

I did try to say! 🙄 Sensible sparky the one I work with, and he is hot on the solar and ev cabling and derating even for less than 400mm.

According to Chillblast today, it's something like this: https://www.chillblast.com/pcs/chillblast-synapse-frontier-ai-workstation - a mere £39,999.99 and it'll give you that magic 96gb. A snip with 0% finance too!

I'll take a deep breath and jump, feet first and see what happens!
