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](h

You're viewing a single thread.
Yes, but, it is also possible to achieve greater than 100% efficiency in using electrical energy for heat. You can use electricity to move heat from where you don't need it to where you want it. The amount of heat energy you move can be greater than the amount of electrical energy put into the system, so it's greater than 100% electrically efficient. It's well below 100% thermal efficiency, of course.

KNEW it was gonna be the technology connections video.
was literally just talking about, and recommended this video, IRL like 10 minutes ago.
THIS IS THE COMMENT THREAD YOU WANT TO LOOK INTO.
who, me ?
