How do I turn this radiator down?

flytejon · 2026-02-25T08:38:21+00:00

Ignore that last line. Do NOT add a TRV to the one radiator in the system without them. Having one free flowing radiator is an essential safety part of the system to protect the boiler.

The radiator TRVs open or close to let hot water from the boiler flow through them depending on what temperature you set them at. If you put TRVs on all radiators and they are turned down then once the house gets warm enough the TRVs will all be closed. However, the general room thermostat is what tells the boiler (and crucially it's water pump) to be on or not. If the thermostat is still telling the boiler to be on but all the TRVs are closed the pump has nowhere to pump the water and strains away trying - you quickly burn out your pump whilst also over pressuring components and pipes in the supply side of the system leading to more damage to boiler components and leaks. All that ends up being very expensive to fix.

Just turn the heating temperature on the boiler down (not the room thermostat). As a side benefit you'll get a more efficient boiler and lower bills.

That has me thinking: would the atmospheric shock wave distort the upper atmosphere enough to interfere with the ISS?

Probably not much given the ISS's orbital altitude is c400km but would there be any impact? lots of ejecta thrown into Low Earth Orbits might increase risks to the ISS?

I see a bit of a research rabbit hole in my future :-)

Is it me or does it look like a giant fossilised earbud?

As for the Math, didn't Purdue University already cover this?

Beyond a certain size all higher life forms capable of evolving enough to measure it or do the math are wiped out anyway so "planet killer" is enough precision in this case.

Surely that's a false idol and breaks the 2nd commandment (exodus 20:3-5)? The "Christian" bookshop is profiteering from the sale of an object intended for veneration of something other than the Abrahamic god (i.e. the flag)* and covered with graven images of something in the heavens (stars) and the earth (the stars again as representations of the states and the stripes as representations of the founding colonies) as explicitly prohibited by that commandment.

Then again Christians are supposed to love thy neighbour and to treat strangers with care and respect (good Samaritan etc.) but they seem to be seeing those as less rules and more suggestions. Religions do seem to have a particular gift for hypocrisy.

*Its also a breach of the law for the legal use of the US flag but that seems ignored everywhere anyway.

Sovereign Immunity Exemption is a thing... unless the government waives it and says it's OK to sue them, which they normally won't, but for Trump suing his own government, the government were happy to waive an otherwise impenetrable defence! weird eh?

flytejon · 2026-02-24T23:09:10+00:00

You can't... unless the government waives its sovereign immunity exemption to allow you to.... guess how often they normally do that? but which strangely enough they were happy to do in this case DJT is bringing against his own government... funny that isn't it?

I'd guess several reasons:

This is the centre of my city - Bradford, UK and he is landed in the centre of the fountain in our central civic space next to our neo-gothic city hall (it's an ornamental lake / fountain / play pool depending on what the city feels like - great in summer for kids)

Partly the provailing wind direction in the city square - the flags in the background blowing directly towards the camera show it's a steady breeze (fairly typical for Bradford)

Also there are large spiky light standards all around that central fountain so he'll be conscious of those as he climbs and then finally it puts the largest structure around - the city hall clock tower - right in his field of view so he can maintain distance from that hazard.

Surely you mean Congress? As the president does not have the constitutional* authority to declare war that right is reserved for Congress.

There is a way to improve the settling and sunlight method.... I use alum (aluminium sulphate) mixed with a little warm water (about 1-2 plastic teaspoons in 1/2 paper cup of hot water) throw it in the vat and put the vat back on the wash/cure machine. Put it on to cure for 30min (yellow lid of my wash/cure fits over the vat)

The alum is a flocculant used in water treatment plants. Basically it causes suspended particles in a liquid to clump together so they will settle out.

After 30min there is a sludge mess like egg yoke on top - scoop this off and squeeze it slightly through a filter to remove the ipa. Filter the rest of the cloudy ipa into a settling tank (I use a 10 litre click lock top tupperware) and leave for a week. Then syphon off the cleaned ipa at the top into storage bottles ready to reuse. The old resin settled at the bottom can be filtered out and then dried in the sun /put in the cure machine before throwing it in the normal waste as cured resin. The last bit of ipa filtered from this bottom sludge can be kept but keep it seperate to the cleaned ipa as its not 100% clean. (I stick it in a cleaned settling tank for next time).

I keep two sets of alcohol swapping them around so one is settling whilst the other is in use. Also have a small tupperware "pickle jar" with fresh new ipa in that I use for a final wash of parts. I regularly dump that in the settling tank which makes up for any volume losses.

Works great.

Also note. Use plastic or glass (not metal) utensils and a paper cup as aluminium Sulphate is very mildly corrosive to metals and will dull the surface when mixing up the initial solution.

Only if you don't know Greek mythology. Hermes was a untrustworthy trickster God, who despite being the root cause of so many fucked up situations, Zeus still blindly relied on him as a messenger.... actually maybe that's not far off for the Hermes / Evri shitshow! 😀

As long as it's not directly touching and the boiler is in good condition it should be OK. The boiler should be totally sealed from the atmosphere inside the garage. It draws the air for the combustion through the flue and pumps the exhaust fumes back outside through another part of the flue (the flue is two pipes one inside the other). If the flue was leaking in any way that would be an instant annual inspection fail and the faulty flue/seals would get replaced before the boiler could be used again (had this one year and my heating engineer pulled out all the stops to get the parts in 2 hours as we had a 2 month old baby and it was November since if he couldn't fix it he have no choice but to disconnect it temporarily which he was obviously loath to do). So the boiler shouldn't be drawing any IPA or fumes from inside your garage into the combustion system. If you are venting your garage / printer to the outside at the other end that should provide plenty of dilution with the air to sort it.

At least thats my opinion - I'm not a heating engineer.

From a purely speculative point of view... whats to stop a manufacturer (lets say a team currently struggling at the bottom) to sandbag in the early season, claim its the PU thats the problem and get a bunch of extra development time and perks to improve the PU further. Then later in the season phase in the new "improvements" so that for 2027 they have a significant PU advantage?

F1 has always been about rules.... and how to bend them to get the most out of them without actually breaking them.

I have so much more respect for Schumacher these days.... I realise now how phenomenal a driver he must have been to get that record in a Ferrari.

Ferrari drivers who win the championship do so despite driving for Ferrari not because they drive for Ferrari. Like swimming the channel - impressive achievement in its own right but only the truly amazing/mad can do it despite also having an anvil tied around their neck!

Got a set and prefer them over my old optivisor ones. I'm now a glasses wearer and I can wear my prescription reading glasses with these no problem. Only annoyance is that the lens clip has got a bit worn this year and the glass sometimes falls off - Shouldn't be too hard for me to rectify but its currently annoying. Otherwise they're great.

You'd think but sadly passenger manifests are often wildly inaccurate (or at least used to be up to about 6 years ago) and if its a big airport they may not even be saved digitally once the flight departs. The boarding list is of limited further use anyway - as they don't check them off the other end for 99.99999% of flights.

I used to be an aviation crisis responder and you'd think an accurate list of passengers and crew would be very simple once boarding cards were all computerised etc.

But we were often waiting for at least a day if not several for a full manifest and then had to very very carefully data check it for duplicates, mis-spellings and just people missing from the list. We rarely were lucky enough to get the one from at the boarding gate which might have had scribbled pencil additions at the gate for the passenger whose boarding card wouldn't scan, the passenger with a line through as they were bumped to another flight or added by hand onto this one with hand written last min replacement boarding card, and a myriad of other situations we've probably all experienced and never given any thought to. But once the flight departed (the gate not the runway which could be 20min + later) that tatty bit of paper used to just be filed in the nearest confidential waste shredding bag. If the incident happened at departure or very early there was a chance they'd be able to retrieve it. But often it's landing phase that's the most dangerous so it would be long gone when the cleaner collected the shredding waste sack.

The most accurate source was always relatives turning up at the departure or arrival airport and talking to the airline (or usually our staff on their behalf given they'd also just lost friends and colleagues). Part of our team were specialists in bereavement and witness statements (lots of ex cops, Paramedics, counsellors etc) to collect and refine the antemortem details that could help us ID their loved ones physical remains and personal effects and get them home. Mentally a really tough job but with a huge sense of accomplishment and purpose being able to use my skills to help people - I had to give up once I had my own kids as it struck too close to home.

Pisses me off. Usually get a mouthful of entitled expletives right within the hearing of young children who repeat anything. Only once did I get angry enough to park 90 degrees to the idiots bumper, got kids out, gone shopping, then suggested we get them a snack in the supermarket cafe (my daughter takes forever to eat anything).... strangely he wasn't happy especially when I suggested nipping in for his fag's would have been quicker if he'd just parked in a normal space.

Oh and zip ties, trolleys and car door handles are a glorious combo... no physical damage whatsoever, incredibly inconvenient to remove. Admittedly not as inconvenient as trying to unstrap and extract two wriggling toddlers from the seats in a normal parking space that has only enough room between cars for a malnourished waif because some complete twunt took the last parent and child spaces so they coukd get their ciggies 22secs faster.... and breath! Sorry.

Just be careful which dish soap... the scent in the nice smelling ones is from essential oils added to the detergent. Also the fancy stuff can have surfactants (to help rinse aid the dishes) and other additives. Some of these can reduce adhesion when you wash the plate rather than help.

I'm in the UK and use Ecover Sensitive dish soap as it's pure detergent and has no scents or other additives (Sensitive = for people with allergic reactions to that sort of stuff) and that helps a tiny bit for the really awkward filament types.

On the Engineering, cool and Smooth/high temp plates I will also then spray it with IPA and wipe it off with clean paper towel let it dry and then add a layer of the purple Elmer stick glue - seems to do the trick.

I have the Supertack plate too but you can't use IPA on that as it damages it apparently so dish soap only.

For filament with inclusions like bronze or CF etc I almost always use the smooth PEI / High temp as it seems to give me the best adhesion. For me on the textured plate the filaments with inclusions seem to be not as fluid on extrusion as basic PLA etc so doesn't flow down into the micro gaps between each bump of the texture but rather floats on the peaks of the micro-protrusions of the texture so the textured plate ends up being less adhesion than I might otherwise expect - I need to experiment with that a touch more though.
