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

      You’re basically going all-in on entropy.

      We all do that eventually.

      I mean, if going all in on entropy is the goal, then space heaters are 100% efficient. If what you’re trying to do is heat a room, they’re also 100% efficient at turning electricity from the wall into heat energy in the room, but heat pumps are far better at that
