Call OSO and ask? I'd guess you are probably be ok as it makes more sense to me to put the VIP on the inside and PUR outer. But it's just a guess. Edit: But if the manual says no penetrations then making the plumber replace makes most sense. If you want to show flexibility then check with OSO and see what they say. If they are willing to warrant based on the screw being no longer than x then ok. No good to move forward with a void warranty.

It is A Rated, and it looks like it does have Vacuum insulated panels and PUR. So where inside the cylinder are the vacuum panels and who thinks they are punctured? The tank is not yet filled or heated so I can't do a temperature test to identify heat loss around the penetrations to determine if the VIP are punctured. Plumber has the hump with me ever since I told him to change the manifold 😕 I think its about to get worse. 😬 What now?

Change this bend from a push fit to a compression. See if that improves it. The seals on those are crap, so the water may be at the bottom of the pipe when leaving, and a gap in the seal may be at the top, and you’d get no water leaking. I’d start there. Also, push a cloth into the hole behind it, to rule out if the smell is coming through the hole and not from the pipe under there.

Use LOTS of 4.0 x 25mm screws to fix the plywood down, and if the subfloor is even SLIGHTLY suspect I put the ply down over a 3mm notched bed of neat PVA.

More on this. There are still old oil tanks available but most people appear to think they have a value so its not worth waiting. I should have bought some a year ago but I guess some people who were unaware of the value of harvesting are now thinking the same now it is obvious. So I may switch to getting a group of IBCs and linking them. Shame about the cost though. I used some years ago as water retention. the planners thought it was cheating I think, as they wanted to spend more of our client's money. It simply involved a rwp into the top of one and tank connectors at the bottoms to link to the next tank.. Or better would be as overflows near the top so the first one fills and is useful. Pumps. Google has been listening to conversations as I got an ad for an excellent looking battery pump by Bosch. It links to a normal garden hose for immediate use. Expensive though. Cheaper are available. though clunkier. I may put an additional tank at the highest point of the garden and occasionally pump up to it. Then gravity can water the garden by perforated hose. I may also fit an old fashioned "village" pump.

Where does the lower pipe (below the floor of the cabinet) go? Any joins in it? Just wondering if the smell is travelling a bit and leading you off track? Smell could migrate into the cupboard and accumulate through those cut outs while the mhvr clears the rest of the room.

Too far for the guy I used last.

wish it was a dry trap - would probably be an easy fix just adding another one in line - or a deeper one. Kitchen traps fine, shower trap fine (and on separate run as these can get vacuumed out easier if combined!) and no dead mice 😁 (or a gone off bag of carrots - had that many years ago in another house, found it eventually disappeared behind a cupboard without a proper back. Believe me that reeked!) yes very much drain smell (from STP). Rapidly concluding to try new/different trap and new elbow. Thinking maybe gas escaping at top of a joint where it won't drip???? but no obvious damage / cracks etc. So so weird............ thankfully this is in plant/utility room where we can shut door - and decent mvhr extraction! Also good we've intentionally left all pipes etc either exposed or accessible AAV internally and also on SVP externally. STP vented with carbon filter on effluent pump pod (gravity fed from STP - kept it separate for ease of replacing pump if it ever packs up - works hard pumping c. 240m, and max 2m rise albeit little head. obviously non return)

Indeed. The MOD have probably saved me on this occasion, but its forever blighted until they build "something".

You are expending unnecessary energy on BBB. Only his view is correct. All others are wrong.

That's enough, I'm out of this. You can feel that you have won in some way if it make you feel better. It's been interesting though to read that such extreme views are, or appear to be genuine. Presses the unfollow topic button........

Join facebook group like bricklaying jobs in xxx area. You can be very strict in your wording of the post which should filter out a lot of shit. Then your getting people who are actively looking for a start rather than begging people who are booked up. I know its better to use a reccomend trade but not all good guys are always busy. You will get some finishing on a job looking for their next start. Especially with the way new build sites are slowing down. You can afford to pay better than the barrons.

Very unclear what you are trying to say there. Are you claiming gas and oil consumption will halve in a decade, or are you claiming UK oil and gas reserves will halve in a decade, or are you claiming global oil and gas reserves will halve in a decade ? We do of course have lots of coal in this country. Ever heard of SMR's. And if the idiots that govern us were even remotely competent we would already have more nuclear capacity. You might also note that France has 56 reactors that provide 70% of its electricity. I believe it is not unusual for the UK, given it is run by total idiots, to have to call on energy through international connectors - energy generated by nuclear plants in France that is always available whatever the weather. Some solar panels are never going to solve that national security issue. Sorry, we can't fight a war today because the sun has gone in. Gas and Oil has always been traded and we have managed very successfully to have gas and oil supplies and it has done a brilliant job of keeping us warm and fuelling our vehicles for many decades. The global market generally keeps prices down for what is a fungible good. We are not going to see all our vehicles replaced with electric in the next 10 years, we are not going to see millions of gas boilers replaced within 10 years. For 50 years no serious politician has ever proposed banning ICE vehicles on national security grounds regarding the supply of fuel. Many countries/organisations hold national strategic stocks of oil and gas. The UK is of course far too stupid to do this effectively with repeated failures to pay for the level of such strategic storage that it should have. If we really are concerned about National Security then we do an odd job of it as we have been closing down manufacturing industry and steel making and the like because our energy prices are completely uneconomic. Really ? So that is why government has to offer huge subsidies/price guarantees to get companies to build solar farms. Of course it costs nothing to put in pylons and cables to connect them to the grid, and the fact they can't produce anything during the hours of darkness, and little when cloudy, and can't cope if temperatures go too high can all be completely ignored when assessing their actual efficiency and true costs. The fact they are made in China is not a national security concern at all. Incredibly few people die from heat in the UK. Overwhelmingly old people with existing medical problems that might die a few months or a year or two earlier than they otherwise would. Meanwhile thousands die from the cold and we definitely need heating in the winter months, But wait, no, I guess you heat a draughty 1930's house every winter using a couple of solar panels - what am I thinking ? Look, overall I think you are trying to simplify a lot of complex considerations and tradeoffs into a hugely over simplified set of assertions. It really, really, really, is not some obvious nirvana to make an energy transition in a decade. It is pie in the sky dreamland. If you don't think about it too much, or research it too much, I guess you can maintain your fantasies. I can assure you it will be a 50 year journey and enormously expensive. Get REAL. PS Come on England ⚽

Way way bigger than a container. But then so are the engines these ships use now.

Cooling is a lot easier a mile deep under the artic ice caps.

Bottom line is it comes down to money depending on the situation. But worth considering (again dependent on specific circumstances) if overpanelling may lead to longer run time/more energy generated in winter. ie. in low light, the panels acting together produce enough to overcome the inefficiencies/minimum input of a single mppt where as two separate strings on separate mppts never get above the threshold. I think this is much more likely in older installs with newer tech it not being a concern but worth bearing in mind.

As we have not met up in person for a while, I’m interested in how everyone’s getting on?

if the SMR was a container sized device that just needed hookup to (ship) power grid, monitoring and cooling - i could see it working if electric drive was used. Then, as you say, the module could be craned on/off fairly easily and exchanged for a factory fresh unit whilst the old one went back to be refueled.

I believe that is exactly what he is. Still something to find out. But yes, we are thinking that the majority of the prep work is stuff we could do so maybe i need to speak to the supplier again. Or just do a deal with the neighbour! 😁

Not completely correct - you must use an F gas installer if it's an F gas, R290 isn't covered by the rules so you can self install it's not a refrigerator gas by the rules as it's propane. However if R32 or any other number other than R290, you must use F gas registered installer. In addition it is not even legal to sell to anyone other than an F gas certified installer, except R290

But if you're neighbour is f-gas certified then you could potentially do the leg work of mounting units, drilling holes, etc, and just leave the pipework ready to be connected by your neighbour. There are other types of AC unit that don't need f-gas certification at all that might be worth looking at. One is just requires two largish holes in the wall and another type use r290 gas though there are some safety concerns there so would lean against in most situations except things like garden building (Other threads on here, have a search)

No expert, just relaying what I've seen online but I think there have been two schools of thought with this. Some of the new SMR designs are really low power using fairly conventional fuels. Maybe still a bit big for big ships but not far off, a revised design is feasible. Big ships are a hell of a lot bigger than nuclear subs. The other strand I've seen is talk about allowing more highly enriched designs on container traffic. ie, 20%, not 5% IIRC. Still way below what is used on nuclear subs and not close to weapons grade. Both cases the thought is that is such that it is a crane on module to the ship and any maintenance is done offship by first craning the module off to a maintenance facility (likely swapping the module with another so the ship can continue service without delay). The engineers on ship are just focused on monitoring it and shutting it down if a problem develops, not actively working on it. But either way I think given the issues you mention I doubt the west produces this technology. It'll get too tied up in red tape. But I can see China pushing ahead with it (or maybe Korea). Both big shipbuilders, both make a lot of money from green technologies and agree with the scientific consensus on climate change, both with significant civilian nuclear experience. Russia has been running nuclear icebreakers for decades (though I think they are more military form reactors).

They completely lost my outgoing tariff from the bill recently. Took an email to their helpline and my £148 bill has gone to £305 credit. They still haven’t provided me anything to validate that with and my home mini doesn’t seem to be reporting properly now.

I didn't think it was reactive but that the heat will kill a river apart from algae etc. Around the Dungeness maelstrom were hundreds of seagulls after fish that are attracted to the warm water. This is a dormant station so presumably was on tick over. There are tales of Mediterranean creatures being found on south coast beaches bug I've no idea if there is any link.

Perhaps ask the UK importers (?) of Tyvek. They will probably take the pessimistic view and tell you to replace (which I think is the way I'd err) but if they suggest another course (leave it, or add A.N Other membrane) then you may have saved some time and a bit of extra cost.
