If a machine is never 100% efficient transforming energy into work because part of the energy is converted into heat, does it mean an electric heater is 100% efficient? @showerthoughts@lemmy.world

Yes it does. There’s no such thing as an inefficient electric heater. I’m the US they sell 2 kinds. 750w and 1500w. The differences between them are all a matter of form factor. Maybe a nice fan to circulate might be what you like though.
But a YouTube ad told me that “a college kid blessed with a gift for engineering invented a heater that uses 90% less energy” and that I should order one now!
God, I hate the existence of those ads. I hope people are smart enough to not get scammed by them, but their continued prevalence suggests otherwise.
