Well I got my emergency alert.
How was yours?
Loud and with a voice reading the message. That might be my Android accessibility settings though 🙂
On EE but connected via WiFi calling if that makes any difference 🙂
@neil quieter than last time? Still a few confused people in the pub, so the message isn’t getting through to everyone, evidently
@neil Didn't notice it. Had to spend 5 minutes looking for my phone after you reminded me, to check.
It did arrive, apparently.
@neil don't think I got it in Mull. Another mobile in house made a funny noise at nearly ten past three. But nothing else. 🙃
@neil Loud and simultaneous across my physical and e-sim. Wasn’t expecting to get it twice on the one phone.
@neil noise was so annoying I dismissed it without reading, just to shut it up. In an actual emergency I’ll have to be more prepared so that I remember to read it.
@neil Being in Germany, I didn't get one this time.
But when our powers that be tested them last, it was an earache inducing cacophony of 30 mobiles going off in my small classroom.
@neil arrived about 3:01 on the three phones in the house (all on EE, at least two of the three on WiFi calling)
@neil Wife and I have identical phones, same firmware versions and alert settings. She got an alert I didn't.
So Vodafone worked and GiffGaff didn't. Reverse of the previous test result.
@neil It came through not only on my Pixel 8 on Lebara (Vodafone network), but also on my Pixel 2 XL ... which doesn't even have a SIM in it.
The notion that the provider of a service, which is made available over the Internet, must appoint a local representative by virtue of that service being accessible in any given country, is, IMHO, absurd.
Questions of jurisdiction and Internet-accessible services are far from new, but I struggle with the notion that, merely by making a service available online, countries expect their laws to apply to that service.
Brought to you today because of Nepal's announcement that it considers "Mastodon" non-compliant with its laws.
Whether it means all Mastodon instances (but not GTS etc instances), or a specific but undeclared instance, I don't know.
That's a nice service you got there. It'd be a same if someone blocked it...
Merely making a service available over the Internet, without targeting it, does not entail "doing business" in any given country (especially if the service is not monetised), or providing a service into that country, or the like.
It is like saying that the moon is visible from that country, and so that country's laws apply to what happens on the moon.
Sure, a country can choose to compel its own businesses - ISPs, for instance - to interfere with their users' traffic, or to adopt national interference measures, as they wish.
@neil Business opportunity!
I’m offering to represent providers of internet services (aka “website owners”, as we say in Silicon Valley) who are in need of a legal representative in Germany.
Modest fees, and I’ll promise to promptly forward any mails I receive from officialdom, right to your inbox!
Hiya! This is one of these issues where I am receiving mixed messages from the legal community. Your take is distinct, or is based upon different premises from what I am assuming?

Morning!
I wonder if it is a combination of:
a) people talking about different, specific laws, which have their own, not unified, criteria for territorial scope. For instance, the application of the UK GDPR to people outside the UK is different to the application of the OSA to people outside the UK.
b) people talking about exactly what the position is under any given law(s) (i.e. what is in force now), rather than whether or not the position makes sense. (e.g. what something is, versus what "good" might be.)
@neil
With the proviso that all analogies are "not quite the same thing" here goes:
France and Belgium share a land border.
If someone in France displays signs and posters large enough that they can be read from across the line in Belgium, in what (if any) circumstances does the Belgian government think it has anything to say about this?
Besides, no one is compelling the people of Belgium to look at the posters or read the signs.
@neil in general i think a country (as an function of the will of the people living there) has the right to decide what types of things are allowed in its borders.
In case of such inherently borderless things as the internet, there have to be ways to make that happen.
Either by requiring services to do certain things, or block them.
If you want to do business somwhere, you should need to follow the law there.
(Requiring actual people seems weird, but if that what they/the law want..)
> If you want to do business somwhere, you should need to follow the law there.
I don't see how the mere availability of a free service on the web means that I "want to do business" in that country.
I have more sympathy if a service is *targeting* a particular country, or its people.
@neil it's the right of a society to decide how they want to organize their lives.
I guess we can agree to that?
From my point of view, what i wrote above follows directly from that.
Lets take social media as an (random, unrelated ;)) example:
We all know there is lots of scientific evidence that algorithms used by some social media sites encourage dangerous/damaging behaviour (eating disorders/tiktok chalenges/mysoginy/inciting violence etc) because they boost visibility of engagement-boosting
@neil ... posts.
If we (for example the EU) require moderation and documentation of those algorithms to reduce this harm, that is perfectly understandable and surely something we all can agree is good?
> If we (for example the EU) require moderation and documentation of those algorithms to reduce this harm, that is perfectly understandable and surely something we all can agree is good?
For services established in/run from the EU, sure.
For services outside the EU which target users in the EU, quite possible.
For other services, by all means block the service, but claiming extraterritorial powers over those other services, no.
If you want to do business somewhere, you should need to follow the law there.
I'm not doing business there. I'm not doing business anywhere. I'm here. My servers are here. I don't even know where there is, or how many there's there are.
I don't worry about the Taliban Government rules on modesty when I walk to the corner shop to buy a SIM and I don't worry about registering the SIM I bought from the corner shop with the Philippine Government but if I host a website on the IP address the SIM card gives me I suddenly need to start caring about foreign government rules?
Nah.
@networkstring @mavu @neil Pre-internet, activities were local by default. At a rough approximation it usually needed some kind of positive conduct in order to be subject to the laws or jurisdiction of another country: setting up a branch there, travelling to it, sending products (e.g., newspapers) to it etc. 1/x
@networkstring @mavu @neil With the internet the question became (or should have become) how to translate that ‘positive conduct’ rule into an online world that is cross-border by default. There was a fair (but fragile) consensus that mere accessibility was insufficient and it needed something more, such as targeting activities towards a jurisdiction. 2/x
@networkstring @mavu @neil However, there have always been examples of states being more aggressive and pushing more towards ‘mere accessibility’, typically for a topic area where they feel particularly strongly that local values are threatened by availability of information from other countries. Online safety is, to some degree, currently one of those areas. 3/x
@networkstring @mavu @neil If you’ll forgive the self-promotion, I wrote a book chapter about this some years ago. Snippet. 4/x https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3161397
@networkstring @mavu @neil Even longer ago I put in a submission to the Leveson Inquiry countering Max Mosley’s suggestion that a website should obey the laws of every country in which it was accessible. 5/end https://drive.google.com/file/d/0Bxrl5E4MR7EgcmNxc2VJaXhTZ28/view?usp=drivesdk&resourcekey=0-4f2yWGCnTOqdcTUofEZayQ
@neil If only we had a meaningful United organisation of Nations that could provide consistency of standards and laws for trans-national considerations, such as the internet.
Although if you turn the argument around - "we will only allow your service into our country if you appoint a local representative that we can hold responsible for legal compliance" - it doesn't sound as unreasonable.
The only reason broadcast TV and radio gets away with it is that it's difficult to block. Things on the intertubes don't have that advantage.
@neil having read through the replies they seem to fall into two buckets:
1. "it's unreasonable for a government of one country to place regulatory burdens on websites from another country unless that website specifically targets users in that country"
2. "governments have a right and a duty to regulate websites that its citizens access and to enforce that regulation by blocking non-compliant sites"
On the face of it they seem incompatible, but imo they're two different things
(1/2)
@neil there's an interesting discussion in the internet neutrality space where the ISPs are asking content providers to pay for transit.
The argument is that content providers aren't the ones initiating anything, so they shouldn't be obligated to pay for transit. The customers are the ones making the request.
Today's trip was to Hurst Castle - a 19th Century fort built around a 16th Century fort.
Well worth visiting and if Mother Nature has her way (having been given a helping hand by us), it won't be around for much longer.
I saw something disturbing this morning.
One of my clients showed me an email. They use Gmail for their emails (on their own domain) and download them locally.
The email officially came from their company president, giving the purchasing department orders to immediately pay an invoice of around €20,000 to a new supplier in the UK. It included all the details and had the invoice attached as a PDF.
The worrying part is that the style and tone of the writing were exactly like their president's. However, the sender's address, while using the correct name, was a generic Gmail account. This immediately raised a red flag for the purchasing department, and they didn't fall for it. It was also easy for them to check because the president was in their office at that very moment.
Looking at the sender's address, it would have been simple for anyone to figure out what was happening, but many people don't.
The accuracy with which they (likely using an LLM) recreated the president's writing style is truly concerning.
@stefano That's only dangerous if a potential victim has 20k spare change laying around 😆
@ricardo unfortunately, amounts like those are in their budgets, so they could pay them
@stefano All jokes aside, wouldn’t a proper accounting department question an unscheduled or unbudgeted expense just because the invoice says "pay now", specially without any warning? 🤔
I wonder how the scammers get samples of the president's emails to use?
@nlarson830 The president is active as he's talking at conferences, etc. I've tested and the LLMs are aware of this person and his style.
@nick no, they have strict procedures for this. But another company I know fell in the trap (anyway, I'm not surprised)
@stefano I'm frustrated because a solution to this problem exists for decades - its name is #PGP. Also it has it's disadvantages, problems and is of course not bullet proof, I wonder why nobody was able to design a GUI that is usable for most users with a few hours of training. You only need to understand 5 % of PGP to be able to use it.
I think convenience and lack of interest (until it's too late) are the main obstacles.
LLM adds a whole new dimension to this sort of thing. I'll watch out for this in my own little world.
@stefano PGP signing is 34 y.o. with several open source implementations that make it easy to sign and to verify email messages. I will never understand why business avoid it
@stefano I’ve heard that they also do this through phone call, using AI mimicking voices.
@stefano This is true. Quite popular fraud scheme in my country (and actually post-Soviet space). So they collect enough samples of your voice to train AI, and then call your relatives asking to transfer money somewhere ASAP. That's one of the schemes.
@stefano As embarrassing as it may be, I once was scammed by someone pretending to be the owner of the company where I worked. I lost approximately $1,000
However, I did learn my lesson and checking the email address of any suspicious email is the first thing I do now
@gabe_saltar don't be embarrassed. In 2004 or 2005, I was scammed on ebay, too. I lost 1700 euros
@stefano Damn! That sucks!
@gabe_saltar it does. I felt stupid. Then I was angry, because it wasn't easy to spot. They stole the login credentials of a legit shop and changed the IBAN. PayPal or other similar tools weren't available. It came out that more than 15 people were scammed, all around Europe. We got in touch with one another and we all went to the police but they couldn't find the money. There's been some money transfer from the original country (Germany) to another, non European country and then...everything lost.
@stefano WOW! In my case the person pretended to be my boss, and asked me to send him money in for apple gift cards... It sounded suspicious as hell, but I felt for it because I was new in the company. It was second week at the job and I didn't know anyone in the company well enough to make the correct judgement call.
I found the whole thing to be embarrassing because my major is in Cyber Security. To say I felt stupid, would be understatement of the year
😬
@gabe_saltar bad things can happen to all of us. But life goes on, and we lean the lesson 😉
Replacing Sky / Virgin media with a Freeview recorder. Looking good so far, it integrates well with all the catch-up setvices, and a software update just added YouTube. #manhattant4r #cordcutting #freeview
# Two thirds of lawyers using AI - with nearly half on off-the-shelf systems
That seems massively high to me.
But then perhaps I am an outlier.
@neil not a single legal professional surveyed said they'd use the extra time AI saved them to write more puns on the Fediverse; so even if the efficiency gains were true, is there any point to them?
Using it, or not using it??
@neil given that survey is from Lexis, who has been heavily pushing their own AI, I am unsure if this was a survey or a scare tactic
@neil You probably don't do the sort of work it can be useful for. Repetitive contracts, patent claims 1st draft, Teams call summaries....
Hmmm, I wonder, I wonder, why my Wireguard tunnel suddenly stopped working (on UDP/51820) after I redirected all packets coming in via UDP between 10000 and 65535 to my VoIP server at the firewall. A true mystery I totally haven't spent 15 minutes figuring out...
@snep I did that once, but for Nintendo Switch. Lots of thinking ensued
(also their port usage policy is utter garbage, "just give us everything")
@forst Ohh yeahhh, they _do_ do that, don't they? "Oh, just port-forward any UDP port to your Switch, what could go wrong?"
I wonder what their recommended solution would be for households with two Switches 🤔
@snep Portforward to both, duuuh /j
@forst "Mom said it's *my* turn on the entire UDP port range today!!"
"Ivan replied that code is either correct or incorrect; there’s no subjective determination of whether it’s high or low… if a coder writes code poorly, the program simply won’t run"
If an engineer ever says that to you, run the fuck away.
The fact it runs doesn't mean it's:
- right
- secure
- maintainable
- efficient
or can handle anything except the single case you've tried.
Every time you scratch the surface of a vibe coder, you'll find delusionally low standards.

Some unsollicited UX feedback:
- "contribution" link leads to a broken page
- List of connected instances: linked text being either the domain name or the instance title is somehow hard to process, is that sorted by chronological order? That list could be tabulated and sortable (a common practice for any list bigger than the screen)

@gyptazy is it generating a lot of traffic?
@bogo it highly depends on the users, their posting frequencies and type of content. Mostly, it’s between 0,2 - 0,5Mbit, but of course it can also peak.
Wow. Not sure what this is from, but QR codes are “fun”.
1. QR is URL that is an IP not a domain. Wow!
2. QR is not as compact as could be.
3, QR may not have required white space.
4. This is the biggie… How the fuck does anyone pick which QR they are scanning?! Most devices make that really hard.
Well done stating the crazy URLs in text though, even if text too small to read!
Have one (sane) URL and a select language option on that page.
This is special!
@revk reminds me of barcode scanner programming books that were just page after page of barcodes you had to scan in order to configure the scanner lol.
@revk I have seen a lot of QR codes (and other 2d bar codes expected to be scanned with a phone) that are unnecessarily small, and have left wondering if anyone actually tested them with a variety of devices. To pair my phone with my car, I ended up using an SLR and macro lens to scan the code and then zoomed in so I could scan it with my phone!
@revk And for some reason, they have a Belgian version that looks identical to the Dutch one. What are the French-speaking Belgians supposed to do?
“We will always work to facilitate peaceful protest and protect the democratic right to assembly, however the actions of this group were unlawful.
“Our officers’ role is to prevent disorder, damage and disruption in the local community and they will use their powers to do this. Any breaches of the law will be dealt with.”
What damage, disorder and disruption? All I witnessed was a peaceful protest
https://www.theguardian.com/world/2025/aug/16/police-arrest-protesters-palestine-action-norwich
‘Police arrested 13 people at a protest in #Norfolk on Saturday on suspicion of showing support for the proscribed group Palestine Action.
A group assembled outside City Hall in St Peters Street, #Norwich, holding placards referencing the organisation, Norfolk police said. The force said they were arrested on suspicion of displaying an item in support of a proscribed organisation, contrary to section 13 of the Terrorism Act 2000.’
Where will this end?
I was curious to see what #BBC Look East had reported on the protest…as their studios are literally within spitting distance of City Hall and the last arrest which I must have witnessed was outside the Forum where they are based.
They have literally just cobbled together press releases from Norfolk police the Met.
They felt no need to view this peaceful protest happening on their own doorstep with their own eyes…

@nick @Geri I used to live in SE London (was born in the area) and remember a lot of racial tension there.. I suspect half the folk at these protests are angry white people from that part of the capital who are still pissed off at the *legal* immigration that has occurred over the decades and made London a multicultural city (and the paranoia about a relatively miniscule number of refugees in a country with 60 million is a proxy for decades of prejudice/racism..)
The UK is a political union that is perpetuated by lies, chicanery, threats, bullying, bribes, corruption and contempt for democracy by its largest member: England.
It has no place in the modern world; it strangles Scotland, Wales and NI and prevents them realising their full potentials. #YouYesYet

This is not a joke... A press release from the UK government about a meeting of the "national drought group", in order to "save water at home", suggests to:
"Delete old emails and pictures as data centres require vast amounts of water to cool their systems"
... while the government also pushes for full-blown investments in, and adoption of, "genAI" (e.g. here ) with absolutely no mention of the environmental costs.. which are surely orders of magnitude worse than whatever a server uses to store old pictures, and for what?! 🤦🤦🤦
This is, to put it mildly, utter bullshit.
You can store a decade of email for a million people—call it 10-20Gb each—in a 10-20Tb NAS box that costs about £2000 and sucks less electricity than a laptop.
The environment agency are gaslighting us. One wonders who put them up to it?
https://social.lol/@robb/115016579150112511
@cstross to put some numbers on it, one of our hosting VMs has ~1200 mailboxes using 1.5TB of SSD. Accounting for the CPU + RAM to allow the mail to be usable and searchable, you can get ~20 such servers on our standard 1U VM host, that uses ~250W. Approx 24k mailboxes on a server. A standard DC with adiabatic cooling would evaporate at most (likely much less) than 3500l of water per server per year or 145ml per account. We're in Telehouse South which uses 40x less water ~ 3ml/mailbox/year.
@beasts @cstross What about the energy and water used to make those hard drives? And the rare metals inside? From what I remember reading, that's where the environment cost is.
So if we keep accumulating data, we'll constantly need more or bigger drives?
Or course it's negligible compared to the energy and water cost of AI, but it's something regular people can do something about. Most people are powerless against the rise of AI and blockchain, but they *can* delete old files and emails from their cloud. Start with small actions, then move on to dismantle useless AI! 😄
@narF @cstross hard to get any figures, but (https://www.sciencedirect.com/science/article/pii/S2666445323000041) gives 2.6tonnes water per wafer, (https://blocksandfiles.com/2020/07/13/kioxia-wafer-scale-ssd-packing-density/) gives 44TB per wafer, so that's 73ml water per email account in manufacturing. We have RAID1 so 143ml as you buy the storage twice.
We're still not yet at enough water to fill the coffee cup you'd drink while working out what emails to delete.
Oh come on… it’s not the private emails and holiday photos that is the problem here.
Address the real problem. Make big tech and AI companies pay for the exorbitant use.
System level solutions please.

The new ChatGPT is apparently "PhD-level".
I submitted the standard question I have for every LLM chatbot.
As with every other LLM-based thing, the answer was wrong.
You do not need a PhD to answer it.
You need a web browser and an understanding of the logical implications of English words like "and" and "or", and phrases like "one or more of the following conditions".
It also subtly changed meanings of various things in the answer. Also, really financially inadvisable to follow the answer.
I must stress: the definitive answer to my test question is publicly available on a government website which is kept up-to-date and is ranked highly in search results.
This does not require delving through complex scientific articles that are only available as PDFs behind an institutional paywall and which require years of study to understand in context.
Every single LLM I've tried either returns out-of-date information, subtly makes it less accurate, or both.

New UK manufacturered Heat Pump 🙂
https://protonsforbreakfast.wordpress.com/2025/07/22/icax-a-new-uk-heat-pump-manufacturer/
@simonzerafa sadly nowhere near big enough, I think.
I would be careful about over-specifing the HP output as it's apparently common for that to occur, depending on property design etc 🙂
@simonzerafa This was a Heat Geek who specced the 16kW .. I trust them.
@nick @simonzerafa I think we are north of 20 rads
Do you have an EPC for your place?
Here's the relevant excerpt from mine :
"Heating this property
Estimated energy needed in this property is:
20,315 kWh per year for heating
3,038 kWh per year for hot water"
My property comes back as a 75 C rating with potential to be 79 (but still C).
@nick oil is expensive compared to mains gas though.
I’d love to get a heat pump to replace this boiler, but my only actual quote so far is £24k … and my other quote which was for £3800 to 4500 ish was withdrawn when they called up. A boiler will be £2500 to 2800 supplied and fitted.
@nick Yeah, but then even the surveys are chargeable. As it is, I had a plumber to the property doing other work, and he quoted (based on being there) for the boiler option.
IIRC both heatpump guys wanted paying for the survey (which is fine, and possibly refundable in some circumstances).
Intuitively I really would prefer, right-first-time fit a heatpump. With the sad reality of the situation, it's looking likely a boiler will be what we'll do.
@nick so quite a bit more than my place, theoretically .. huh
so a 16kW heat pump does seem excessive then
I probably have one somewhere but our house is non standard construction so a HP isn't going to work, without basically rebuilding it.
We've installed a efficient gas boiler, have log burners to make use of ash dieback sourced wood and an EV using off-peak charging.
Triple glazing is next before the autumn 🫤🤷♂️
Our boiler is dying. The heat exchanger has a very slow leak, slow enough that it dries up before leaving the case of the boiler. We had booked a boiler service, and the plumber was extremely decent, said he wouldn’t condemn it as it wasn’t a safety issue but that it would want changing ideally. New boiler £2500 - 2800 ish. Now our plan was to put in a heat pump and ditch the gas. 1/2
2/2 But I’ve approached 2 potential suppliers for heat pump, and one initially gave a price in the mid thousands, fair, I thought but then called me a couple of days later to say actually the only pump they install isn’t big enough so later in the year ask again as they’ll have a bigger one. The second potential supplier gave me a quote of £24000. Both these quotes take into account the 7500 BUS grant.
So um, looks like, sadly, I’m sticking with burning gas then?
Continuing… it is possible to DIY a heat pump in a way you cannot DIY a boiler, and I have found notionally large enough heat pumps for between £2000 and £4000. My sort of idea would be to throw one in, almost intending and expecting efficiency to be not great, then gradually replace pipework / rads etc to bring it up. I do have friendly plumbers etc. But the no brainer is “get a new gas boiler” which just feels sad.
@bloor Where are you based, eg in the UK? Have you tried (say) Octopus?
Also consider at least temporary electric boiler while waiting for a heat pump.
Also consider air-to-air unit(s) for main living areas, at least to tide you over but also to allow cooling.
Also: "hybrid" heat pumps (with gas) are a thing.
@EarthOrgUK yes in the UK and it was octopus who initially gave me an acceptable rough estimate but then called and withdrew it, sadly.
@bloor @EarthOrgUK Was going to suggest Octopus as a starting point price.
Re the hybrid heatpump, wouldn't that basically be the same as some A2A units dotted around and a boiler for when it gets real cold outside?
If I did do the DIY route, I could very accurately monitor the base efficiency with open heat pump monitor (same organisation as open energy monitor) so as I made improvements I could see this in SCOP value rise. But IDK…. It seems like a risk with a fairly important system
@bloor Is it an especially large or poorly insulated place?
A colleague has a million pound house in bagshot and was quoted less than £24k
@wishy yah very similar situation
@bloor Have you had a winter in the place yet? Maybe you can use the gas consumption data to work out your thermal losses more accurately?
What size HP are they proposing?
@wishy yeah had one winter so far.
@wishy the proposal from the “really good” firm was for a 16kW pump I think. Or perhaps 18kW.
@bloor @ahnlak So ~200kWh on a peak day in december, which is 8.33kW average in a fairly (but not exceptionally) cold winter.
That's a lot of thermal losses TBH, obviously doing what you can to insulate would be hugely helpful.
That said, 8.33kW isn't 16kW. Some element of over-sizing is to be expected, but this seems exceptional.
Also don't see a good reason your A2As couldn't be considered in the calculation. How much heating capacity will they have?
@bloor @ahnlak Maybe look at how much extra is costs for bigger A2A units which can help meet heat demand in the winter? Also if your losses are high in the winter, they'll also be high in the summer, so a larger unit might make sense..
Use the more efficient A2W from Autumn to spring, use the slightly less efficient A2A in colder periods?
As to if you can make MCS accept multiple sources? Dunno
Also a pellet boiler might not be utterly insane... And CHP
@bloor
"In theory" it should be possible to rig a system so the gas boiler 'tops up' the output of a heat pump, but whether it's actually possible to find installation engineers prepared to do that I have no idea. I'd definitely be tempted by the idea of maybe DIYing a heat pump only for certain rooms, or something - I don't know if aircon units with a heating mode are an option there?
@bloor Why do heat pumps need special pipes?
@mansr In order to run most efficiently, you want a low flow temperature and to run the system near constantly. A boiler runs the circuit very hot, and either on or off (oversimplification). A heatpump runs the circuit at a few lower temperature, and continually. As a result of the lower temperature, you need higher flow. So rads connected with 10mm may need higher bore pipework. For instance. It isn't per se that heatpumps need fatter pipes, it's that maximum efficiency can be achieved this way
@bloor How much power does the circulation pump use compared to the heater? If memory serves, the pumps where I've lived have been marked 50–100 W or so. If the heater is delivering a few kW, doubling the pump power shouldn't make the efficiency dramatically worse. Enough to be worthwhile optimising in a new build, sure, but how long will it take to recover the cost of replacing all the pipework?
@bloor ZAR 24 000 would be a reasonable quote here. but £24000 is over ZAR 500 000
@mensrea for what it’s worth I’m sure it’s not a rip off; this particular installer is amazing. I’m not saying it’s not a fair quote. It probably is. But it is still high for me.
@bloor i'm sure, i also don't understand the ridiculous price difference. my father had a system installed end of last year (i think) for a large open plan house. primarily for cooling, but i think the total installed cost was under ZAR 50 000
There's nothing inside heat pumps that is much different from what's inside the reasonably priced air conditioners on millions of window sills around the world.
@Walrus I know. I have had several a/c units, and installed them back when that was legal, and so on. But the deployment of air to water; especially with low flow temps, does have very different challenges than a simple a2a split.
But nothing that we don't know how to build, I imagine. Current prices seem like exploitation.
@Walrus I think it may be more on the “implementation” side than on the physical build of the pump. As an example I can buy a HP of the same approximate size for £2000-4000 depending on brand. But once you start replacing rads, and even worse, pipe runs, that all incurs significant labour and making good. Which costs £££
@bloor Blimey. I had an ASHP installed two years ago. Daikin 9kW, 6 rads, bit of pipework tweaking, by Octopus, 11k all in. 5k off that for the BUS which went up to 7.5k three months later 😶
No real op cost saving but using approx 1/3 the energy overall. Three adults in the house most of the time, four when eldest is home from uni. They'll both be gone from late September so we can turn rooms down too then.
@greem we have a comparatively big house just for two people, so I suppose some stuff may be higher pro rata
@nick yep, their HP is too small unfortunately, and they only offer the one model - a new one maybe out later in the year but I think the boiler might be fully dead by then sadly
@bloor our current plan is to let our very old and inefficient (but reliable) oil boiler limp along for as long as possible to allow the heat pump industry to level up a bit more. Hoping it'll last! Shame yours isn't doing :(
@bloor I got a quote for a heat pump install.
Even when we've finished uber-insulating everything, we would need 2, and if you don't remove your old gas boiler, you aren't eligible for the grant.
I really wanted a ground-source heat pump, but even though we have a decent-sized garden, it apparently still wouldn't be big enough for one of those :(
@bloor It depends on what the size is and what kind of installation you want.
I DIYed my home (Netherlands) using ACs with multiple outside units and that was about €6k (5 indoor units, all Daikin, 3 outdoor units, total power about 15kW), which keeps us nice and toasty.
Technically, I wasn’t allowed to do that (no F-gas certs), but I took more care during the install than our previous installer (who didn’t pressure test with nitrogen at all). In the end, a befriended certified plumber slapped a sticker on it as it was properly installed.
I still need to replace the water boiler though.
Our place in Italy is a different story though. We have a single 35kW (Daikin) outdoor VRF unit with 10 indoor units which we HAD to use plumbers for (Italy is quite strict). We slapped on a heatpump boiler for hot water.
Total install was €39k, which was one of the bigger parts of our renovation. But we now also have AC in summer, which is nice.
@bloor I'm curious what life you got out of the boiler. Our previos one just about managed to survive 12 years but had been touchy for ages. Is the cost of replacing the heat exchanger not worth it?
@penguin42 Well we have only had the house 1 year. But anecdotally the boiler is 15-20 years old.
@bloor Ah ok, so yeh probably not a terrible life for a modern boiler.
@penguin42 yeah it's just the timing; i had/have good intentions to do a HP replacement... but it feels like this has happened just a bit too early
