Don't take this the wrong way, but what you've just written is utter tosh. 160mm deflection isn't even what the Severn Bridge has accounted for!! Get an SE involved immediately, as you are severely out of your depth and are just making crazy assumptions. FWIW I really do not think you need any prop or column, and I'd ask the SE to sister 2 beams side by side, across the internal leaf and the end wall, and then beef up the intersecting beam to suit. Or bring another steel further inboard to break up the distance of the intersecting beam. Hard to say without lengths, loads, sectional drawings etc tbh, but an afternoons work for any good SE. As I said, I've seen bigger unsupported spans many times before......

Happy days, sound like they would be amenable to that.

If you take the settlement then they wash their hands of it, and make you sheriff of the funds. Then they will close the case. I'd grab the £4k is a split second tbh, and then organise the trades yourself paying nominally and stay in control of it all. You should end up with change. I assume the £4k is (slightly) elevated to account for lost income from renting? If not, you need to go back and ask if this can be revisited. Long and the short is, they usually offer a 'gift' (dangle a carrot) and hope you grab it, as the logistical issues and responsibility for them then vanishes into thin air.

Make a complaint.

+1. Running leads that far will be a liability. Also, it would need to be a larger 32a transformer instead of a regular 16a, as the second more than one trade plugged into it you’d be tripping the overheat cutout on it every 5 minutes. You need 230v on site, as every trade will have battery chargers with them and will not want them out of site / mind, as batteries are expensive and ‘walk off’ quite regularly. Hook the 230v up and get at least 3 metal clad double sockets installed for the duration, on a ring main fed from a 32a breaker in a local CU. Also, not sure what you’ve been told, but an electrician doesn’t “install” a 110v transformer…..you just simply plug these into a 230v socket?!? A 10 year old can install one , so don’t be paying for it!

Can’t you go for stronger beams and do away with the prop? An SE would look at alternative solutions. I’ve seen longer runs unsupported. Theres a few ways to approach this, so I’d suggest you don’t assume any more, and get some proper professional input. SE for a job this size won’t cost much, but will be the best money you spend, (plus, you’re going to need one later anyways)!! I say get one sooner

I change to a more serious side if the steels outside the heated envelope, or is captive, or as you say part of a group of connected steels. Then you’re into elongated bolt holes etc and mostly mechanical joints, so I’ll stick to drawings at that point as it’s above my station.

I had the little bastards under my shed. I drilled a small hole and piped the exhaust from my generator into it and gassed the bastards.......or so I thought. 2 days later the hole had grown by 30mm....ffs.

We did, and 35 years of experience, plus 30 years of experience, plus the SE drawings should remove any ambiguity or concerns. If thing's I've previously built started falling down I'd seriously look for a new job. So far I've not met an SE who didn't concur that my 'bespoke' solutions would pass with flying colours. Don't ask me 'how' I know, but I just have a sense about these things, I come up with complex solutions, and they work (with professionally underwritten approvals). I'm not bragging btw, this is probably why I get only a few hours sleep each day.....I would welcome being dumb and well rested, trust me!!

Yup. Steam on 👍👌

I always fit a raw cold supply to the kitchen sink for ‘human consumption’, and usually that’s in the form of a 3rd party faucet or a filtered water gadget of some sort, often preceded by a charcoal or other filter. I worked for 2 doctors and they didn’t have stupidly hard water so they instructed me to put the softened feed to the kitchen mixer tap as is, with zero faff. If 2 doctors will drink softened water then who am I to argue?

What mileage have you got out of the units over 25 years? Same one or 2.5 replacements?

Sorry, yes the larger capacity units can. I meant the single 'cartridge' types are usually not 'man enough'. Multi-tasking atm which never goes well....

@Walshie Room in roof or warm attic?

You didn't have to reread it furiously lol . Just wanted to check.

Kinetico are more for single appliances like a drinks dispensing fridge or filtered drinking water tap. With the hardness you state and the amount of caretaking you have to do(!!) I'd expect the to jump directly to the recommendation of a proper, whole of house water softener.

Defo should have an additional layer of PIR going over the rafters to the room interior, to stop the quite adverse repeat cold bridging; (25mm to 40mm thickness for this layer, depending on how much head height you can sacrifice?).

Typo (75mm should read 175mm?)

No need! Details are what we need to be able to help you best. For the one 9" away, over the LB wall, you can simply add a section on the end, supported by say a 1800mm long new section sistered alongside, making as you sat a 6x7 there. For the other side you can do the same again, but this would ideally need to be the full length, and would be subject to the condition of the timber (at the end opposite the chimneys) being in good order. If in any doubt there, you'd need to cut a new pocket alongside the existing one for the new timber to slide into; if it were my own place I'd do this first as last to be sure. You probably cannot get a full new timber in as the new timber would be longer than the width of the room. The piece 3" from the wall is a simple swap out for a new piece afaic?

Ah. Crossed with your reply. But yes……it’s a no.

There’s a WWIII type thread on here from when the good folks from Halcyan tried to get these snake oil type devices ‘green lighted’ here. They left defeated. To not beat about the bush, these things are all shite. You need a proper, water SOFTENER, and with the level of hardness you have there’s no way around it. Eventually this will cost you in damaged / perished items so better to bite the bullet and just do this properly.

You just answered your own question. Pics please!!

Not really... In a nutshell. Look where the rainwater, if any, would end up, well away from causing you any harm. The membrane outside the TF extremal skin would brush of any storm-driving splatter, for the occasional storms, but at the size of the gaps and the overhang, it's a non-issue in real world terms.

@gambo

Yup. I always fit 2x thermo probes if I can't install the conduit to change them out at a later date. I'm not able to advise as I've never used Schluter, so it may be better! Have you a link to the one you are considering, or at least just get the spec sheets alongside each other for comparison. The benchmark for a good unit is a bit of self-learning for setback.
