Not true, it is true that it is heating at %100 efficiency that is to say %100 of the electrical energy is being transferred into heat (although technically some is being transferred into IR light not necessarily what you want) but your goal is probably not to simply create heat your goal is probably to heat the room or at least yourself and their is plenty of waste heat going off into space somewhere also you can achieve more than %100 heat transfer by compressing the external air's heat we call these heat pumps and they can achieve +400%. The key word is efficiency.
It’s always wild to me that 100% heating efficiency is actually kinda not great. Also the fact that we can use the heat from air that is colder than what we want in order to generate more heat I mean that’s just witchcraft.
Well, we're not generating heat with heat pumps. We're compressing atoms to make them angrier and pass other atoms by that bunch to even out the angriness. Could also substitute the word jiggy for angry.
Huh, so what if the jiggy atoms come in contact with batman atoms?
Then Batman is going to have to get jiggy with it.
Na-na na-na nana?

Superman tries to shake off Batman, but Batman just smiles and tenses his anus even more...
I am appalled, but... That's just... I'm speechless. Genuinely.
These are not the facial expressions of distressed men
And since very little heat is generated, we don't further heat up our planet. Not much, anyway. electricity generation is another issue if it's fossil based, but at least less is used.
I get that(enough, anyway, I just need to watch some videos on them to be honest) but it’s still super wild to say out loud.
Which part, getting jiggy wit it or the witchcraft?
I always like to muse that in terms of electronics the heat is caused by resistance to current and that heat is usually considered inefficiency, and since no other load exist or work is done that means heating elements are about -100% efficient.
🤓 ACKSHUALLY
It's not possible for a heat pump - or anything - to even be 100% efficient, let alone 400%. Efficiency is measure of how much of the input energy gets converted to useful output energy, and since heat pumps don't actually create heat the useful output is the compressor's ability to pump refrigerant about. The Coefficient of Performance - the ratio between energy put in and useful work done - is 400% for a heat pump (give or take).
🤓 ACKSHUALLY
Heat pumps create a fair bit of heat due to friction and electrical resistance in the compressor.
🤓 AKSHUALLY
Energy is conserved. It is converted from another form of energy, or in this case mostly transported, not created.
Heat and energy are not the same thing, scrub. You can create heat no problem.
Fuck me, every time with this "useful heat" bs...
ir light is heat dawg
