If we get most of our supplies from Canada, wonder what the economics would be of keeping a floating reserve. Save building space on land and double handling. Just buy/pay for extra bulk carriers and keep a number in a queue to build a buffer. Possibly could slow the transit down too to save fuel to lower the overall cost. (I assume current ops are optimized for cost, so balance of fuel use and time underway). Especially as a short term measure while renewables build might make some sense.

Batteries in plant room and 120 minute fire rated walls

thousand Will be interesting exactly what was in there but expect it to be a lot. Those disposable vapes are such a travesty and if they sold disposables I'd bet they sold rechargable ones too along with spare 18650s. Wouldn't be shocked if the basement/back room was full to the gills of batteries/battery containing supplies. Plus they are the high energy, very flammable LiPo. Not LifePo4 -

This surprises me, at least on a masonry build with a decent cavity. I can imagine localised damage that needs work but totaling the house? -
Talking a 90 day reserve. Drax currently burns it but not sure what else. Assume we would be wanting a reserve that could be burned for 90 days with Drax flat out and likely some other plants also. Agree.

I think when we shut down our coal plants a significant proportion of the coal they were burning was imported. Not sure this would add up to much, and if you are paying to have electricity generation as part of the incinerator plant then you are generating energy during normal operation. Edit to add: and non-incinerator plants don't have the filtering to clean up the emissions from waste. Best backup we have available to us easily is to reopen gas storage facilities. We could have 80-90 days storage of gas available if we wanted to at reasonable cost. We aren't far off from not needing fossil fuels during the summer months. Lot further to go during the winter months. But still as we deploy more renewables the amount of time that the same amount of gas storage buys increases. None of this helps with short term spikes caused by the current crisis. But at least it is happening as we are coming into spring where our need for gas/heating oil is limited. Edit to add: if you want non-gas, burnable storage, maybe store a stockpile of wood/biomass. You'd have to store it in a way that won't rot down over time (woodchips not a great way to do that) but seems quite doable.

This is the huge saving vs Gus' estimates. DIY bearing replacement rather than replacing either the whole unit (which seems excessive but might happen if parts unavailable) or replacing the whole fan using a professional likely adds up to a saving of £500+ each time. Important that you choose an MHVR with a fan whose bearings can be replaced. From reading hear some fan units are very difficult to service like this forcing a whole fan unit replacement.
-
If the price is good compared to others then maybe worth buying on the basis that you might want to be replacing the polycarb at a later date. I'd guess the polycarb will last a while then all go at a similar time. Glass would get broken one at a time over a period of time requiring occasional replacement. Either way you are replacing bits.

Completely anecdotal but I've seen more reports of fires from loose connections on 48V wiring to batteries than I have of LifePo4 batteries burning. -
Alter ASHP hot water hysteresis?
-rick- replied to Tom's topic in General Self Build & DIY Discussion
Though why bother? I doubt the system is using much energy with it's current behaviour so overriding it isn't just one more complexity that can cause problems. -
The big risk was they'd run out of defence missiles rather than the attack ones. They have virtually unlimited supplies of JDAMs, much less long range weapons but they don't really need them now they have destroyed everything Iran has to shoot at their planes.

I lean towards Trump getting bored and declaring victory in the next week or two and things will become more normal (possibly with occasional lash-outs by Iran). In which case doing anything as a kneejerk reaction is a bad idea. If that doesn't happen and instead Trump decides to send in ground troops then the global economy is in a world of hurt. The impacts of that will likely be different from COVID so things that might have worked during COVID likely won't work here. My thought is to focus on being prepared. Know the different suppliers of things, monitor the pricing, know what you will do if something is unavailable. Basically plan for contingencies and be ready to act if something you need near term is becoming difficult to source (or is being offered at a big discount due to a cancelled project). But I would think that panic buying anything is just as likely to go wrong than right.

This is a good goal and I think that is an area that could be improved in the original design. Especially upstairs. If accessibility is a concern then the squarer bathroom is better than a long thin one.

TBH after looking at the others they seemed less suitable. They seem to require custom trays for the bins and they are focussed on bigger commercial size bins. But seems to be plenty of options so I'm sure you can find something if it's acceptable as a solution.
-
Based on what they say, maybe it would be sufficient to provide storage space/charging connection for an electric assistance device to move the bins, without actually committing to purchase one?

Gah, well this got on my mind so I went down a rabbit hole. There's a whole range of solutions out there: https://www.mastermover.com/applications/bin-mover https://bintowa.com/ https://www.industar.co.uk/product/tow-tugs-electric-movers/small/ https://wheelieezy.com.au/ https://emoveit.com.au/product/wheelie-bin-aluminium-trailers-3-x-240l-bins All look pricey or need a car/buggy but if its the difference between using the plot or not maybe worth it as a last resort.
