I'm confused, most heat pumps have a COP around 4 at maximum. Are you sure your boiler is only 4Kw? Most are over 20Kw...
My current boiler is 27Kw, in order to replace it in direct thermal energy terms, would probably require a 7-8Kw heat pump, which is close to the 40A breaker. It wouldn't need to be run at full whack most of the time, but when it's very cold outside, the COP also falls, so needs the ability to pump a lot of heat.
Obviously, in the real world a whole lot of other mediations will need to be taken. Like improving insulation, bigger radiators for lower temp. running etc...
Thermodynamics is always king, (even for you Maxwell's Demon!)
It's a personel lottery...
One voice sounds caring but isn't, the next sounds like a sullen teenager, but has just sorted your issue out, given you a discount and reset your line profile to give you 20% better speeds..!
I've dealt with BT in so many different ways, and it's always the personel lottery, every transfer.
Whilst I wholeheartedly agree with what you say.., I'm also getting quite tired of all the pointless things I have to learn, only for someone to randomly decide "it's all change, relearn the old skills...'cos!"
I mean, how much space is left now? Surely without an MIB style eraser, I'm gonna run out!

Actually, she hasn't got a clue what any of it really means at all...
They stopped trying to be rational when they kept getting the "this won't work" response, so now they just want to bully everybody into complience without having to provide a solution... "It's the LAW!"
Given the current debacle in parliament, how she has the cheek to talk about "moral imperative" I cannot fathom.
"The internet has become a dark, sombre, dog eat dog courtyard in which the weak are preyed upon and idiots are hoisted onto pedestals for no apparent reason..."
Reminds me of a Hunter Thompson quote:
"The music business is a cruel and shallow money trench, a long plastic hallway where thieves and pimps run free, and good men die like dogs.
There's also a negative side..."
I suspect that the advent of digital mixing desks / studios was quite a complicated and protracted change across the industry.
When I did some recording in a studio back in 89 / 90 they were still very much analogue, from capture on multitrack tape to mastering. There were digital effects (Akai sampler, synths etc.) and there were DAT and CD for take outs.
I doubt that any digital desk was upto the same standard back then, but things sure changed massively over the next 2 decades..!

You need a pre amp that has a specific frequency response. Records are purposely recorded with a boosted low frequency, that needs to be reversed on playback. Often this is cost cut down to a treble bypass cap somewhere, sometimes even cheaper options are taken...

Been to quite a few over the years, but the best was Berkley.
I cycled there after hearing about an open day, and well I hadn't realised...
There station had been shut down and whilst they were waiting for the fuel rods to cool, they had the place totally open (ish). So whilst any actively 'hot' areas like the cooling ponds or fuel handling areas were closed, you were left to wander freely around the reactors and over the charge caps etc...
They also had a big marquee with lots of cool stuff like early solid state detectors with gamma spectroscopy.
The Nuclear Electric reasearch labs were there as well so lots of boffins too.
I seem to remember getting home quite late :)
Mouser jogged my interest with a new product line:
Osram Multizone ToF Sensors. (TMF8820, 21, 28) Tiny little SMD LIDAR units (2mm x 5mm approx.)
Upto 5m range and upto 8x8 zones. Multiple targets in each zone, you just get an I2C signal giving you the range of each target in each zone... They even have 2 GPIO pins!!! All for under a tenner.
However I don't presume Apple had much to do with their development.
Given how the perceived sound changes as the sheet is manipulated, I suspect the frequency response issues are mechanical in nature.
Maybe if a large sheet was tensioned in a frame you could get some good low frequency response.
I'm thinking of a solid state version of the legendary Quad electrostatic speakers...
They also store spent fuel there, any kind of explosive ordinance anywhere near this kind of facility is just batshit insane. You have so many obvious examples of how wayward even the most upto date munitions can be.
Please stop trying to make this OK, it's just not, on any level.
Everybody knows you SHOULD only listen once to each disc, I mean how could it possibly sound as good the second time?
Maybe if you used £30k+ rig you could recapture the first play experience, but a TRUE audiophile wouldn't even contemplate it!!!
You'll be telling me you use ordinary 'room' air for listening next!
I'm not sure, do you mean that a significant section of the public who got their way, are now moaning about it?
If so, I guess you're right. Evidence suggests that democracy is equally bad for everyone, or something...
I wonder if many who voted to 'just make it go away' feel their choice was vindicated or not?
I still feel like I need lot's of these every time this nonsense occurs >>
Nonsense, honestly you are so wrong...
When do you get one leaking tile behind a solar panel? When you installed on the cheap, and failed to maintain your roof before fitting.
From my direct experience, a 12 panel install produces approximately 5 units a day on average (over 10 years or more), that's actually around a 40% saving on the average daily usage.
12 units a day is around a £1000 a year, so you're saving £400 a year, before any feed in tariff.
In the case of this particular installation, the feed in tariff was around 50p per unit produced (yep, that high!), meaning approx. £900 yearly income...
Paid for it's install in 6 years, and that's not including all the direct savings of power and the payments for overproduction.
Indeed, the Big EaARS I attended more than a few years ago had a Rattworks Tribrid* launch!
It also had one of the best firework displays I've ever seen...
The Robin Reliant shuttle used 6 Contrail O class hybrid motors, that are 6KN average thrust, 4 on take off, and 2 air starts...
The video seems to show a very poor start, too much smoke and only diamonds at the end.
6/10, not too impressive, but to be encouraged anyway!
*Tribrid, is a hybrid (ABS/N2O) that transitions to Methanol/N2O: http://www.rattworks.net/research_tribrid.html
I guess it isn't really necessary for something to be a 'jammer' to jam the signal...
There are plenty of illegal 2.4Ghz video senders (analogue signal) with somewhat ridiculous power outputs. 25mW (the legal limit in the UK) is a bit flakey over distance, so I can imagine the more powerful (2W and more) units finding their way into security camera setups.
If your RC setup has played nicely (LBT etc.) with the other transmitters, and found it's chink of frequency space, it's easy for a somewhat broadband, analogue signal to swamp it out.
I do wonder about failsafe issues, but a big bird like this will possibly 'idle' a long way...
The important bit, is that there are schemes to separate the actinides (long lived radioactive 'fuel'), from the fission products (highly radioactive, shortish lived).
If you do this the actinides go back to the breeder, and the waste fission products need storing. However, these are fairly short lived, and within 250 Years would be reduced to almost background levels.
I can think of several 250 year old structures that are pretty solid still, in fact if they'd been stored in some of the local mines when they closed, we'd possibly be trying to mine them as a source of transition metals...
