You’re promoting your closed source, non activitypub platform on Lemmy. Good luck with that, I’ll give it a free, federated downvote.
I’m not saying it can’t be done. But a larger heat pump and replacing all radiators drives up the cost, there is not always space for a bigger radiator, (and water tank), and while higher flow temperatures are possible, it tend to reduce efficiency. Sometimes it’s just not worth the investment, not helped by the big gap between gas and electricity prices in the UK
Maybe it’s me, but that post title just hurts my brain.
Something to do with physics. It’s not just about the heat output from a gas boiler vs heat pump. It’s the output from the radiator to the room that matters. For the same output, a gas boiler heats the water to a higher temperature than a heat pump. Which means a radiator gives out more heat to the room. As an extreme example, if it is freezing outside and the heat pump produces a lot of water at 15c, it may have a high thermal output but still wont keep your room warm. If it produces water at 30c, the radiator will transfer some heat to the room, but unless the radiator is very big or the room is well insulated, probably not enough.
Link me to a heat pump that produces water for central heating at 70C or more. Typically, flow temperature is closer 40C, which won’t heat the average house unless you increase (possibly double) the size and/or number of radiators. Which is expensive and not always feasible. You can run heat pumps at higher flow temperatures, but that reduces their efficiency. Don’t get me wrong, i think they are great. But successfully retrofitting to old UK housing stock needs expertise that is in short supply.
Heat pumps are great when the house is designed for it. Average uk house with shitty insulation and radiators that are unable to heat the room unless the water is really hot - it’s not going to work well.
Only six smaller airports have installed the new (bigger, heavier) scanners needed. All bigger airports have missed the deadlines. Not enough space, floor not strong enough etc. And now it appears the new scanners cannot be relied upon.
Old news, and two similar posts by OP in this community. So take my downvote
Thank you. We need an amputator bot on lemmy
Ukraine and Isreal are not very expensive. Ukraine gets mainly leftovers and Israel pays for most stuff. And both keep the MIC going.
Unless you lost a /s there, the billionaires will continue to earn money. It’s the rest of us getting hit with the cost.
Not everyone who speaks Russian wants to be Russian.

Agreed. And the electronics community suggested above has 2 posts in the last six months. So not really a better place to post imho.
That may be interesting to politicians and economists. But GDP shrinking or growing by 0.x % makes no difference to most of us. Not until shrinkflation, above inflation annual price rises baked into contracts for mobile phones etc and general enshittification are dealt with.
Downvoted for paywall link
In other words: calibre.
It does all that and more
Of course they are bad at solving problems. The I in LLM stands for intelligence.

I agree, they haven’t got that fine, never mind actually paid it. But it would be about a third of their profits, not exactly negligible, and it could double for repeated offences.
