Pure physics-wise, you are correct. Heating the same volume the same amount requires the same amount of heat energy. The difference is the source of the heat energy.

A resistive heater produces the heat by consuming electrical power only, 3400 BTU/hr generated heat requires a bit over 4.2A of 220V electricity to flow through the resistive element. (specs from a Radiant Cove heater unit)

A quick intro to the refrigeration cycle can be found here https://www.swtc.edu/ag_power/air_conditioning/lecture/basic_cycle.htm.

A heat pump is the same as an air conditioner or fridge, just installed with the condensor inside the building and the evaporator outside. The primary heat source is the outside air and the only power is that needed to power the compressor unit to move the working fluid through the cycle. The smallest Fujitsu unit generates 11000 BTU/hr using 3.7A at 220V.

Basically the answer is the same amount of energy is needed for the same heating, but the heat pump uses a different source and an efficient process to produce the heat than a resistive load does.

What the GP is calling a wire transfer isn't what we civilized bankers call EFT, it is the Western Union telegraph-style transfers. You pay Western Union, get a unique ID code and send that to someone else who with that ID code can receive cash from another Western Union office elsewhere in the world. No destination bank account needed. That's what is referred to in literature and old movies as "wiring someone the money"

What we, the non-US bankers, call wire transfers are interbank transfers as you describe. In the old days before internet/ATM banking, you'd fill in a form and the bank would transfer the funds electronically via the dedicated wire links between them. We now call them EFTs because the entire process is electronic. Banks should just scrap all their historically-derived terminology and settle for something simpler.

As the set of planets grows, theories will have to change as we have based the original ones on a single sample that may or may not be representative of the full set.

It's like basing an entire theory of construction of buildings on De Aar, South Africa and while it may explain most small towns, the suburbs of most cities, it will fall apart completely when you try and explain Manhatten or wooden houses in the US with it.

Why is it a shame? It's about time scientists stop being apologetic and point out directly how stupid some interviewers are during the live interview. I guess some pedants are going to point out ad-hominim or whatever, but in this sort of case where the interviewer is deliberately ignorant, that is what is needed.

Every single night I see murders and stabbings on TV news, and you are citing WIKIPEDIA to "prove" otherwise? You sound like a fucking retarded gun control advocate trying to convince me to give up my primary source of personal protection.

And you've just proved you fall for the sensationalist media like Musk is talking about.

You probably didn't even look at the first paragraph of the Wikipedia page where it clearly states the numbers are pulled from FBI and BJS reports, both government sources that you can go for primary data if you think Wikipedia is fudging the numbers. You also didn't look at the graphs in the articles, nor the data sources behind the graphs, as there is a clear downward trend in most violent crimes. Wikipedia may be untrustworthy, but there are citations and those can be verified.

Well, the fact that it routinely fails to kill or cause massive illness in the millions of people who do eat it makes it fine in my book.

You soft westerners have too low a squeamishness level. Harden up a bit and enjoy your food rather than worrying that it will kill you when obviously it doesn't.

Fish sauce didn't kill the Romans and it won't kill you.

How is this "from people that don't receive any service from them"? If you don't have a solar panel, you don't pay it. If you have panels, but don't sell back to the utility, you don't pay it. If you have a panel, you sell back to them and they have to provide the infrastructure to do so, then you pay the extra.
