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, except a heat pump is capable of being more than 100% efficient because the using the power to move heat around is more efficient than converting power directly to heat
but but muh thermodynamics
I get you are joking, but incase someone doesn’t see the /s. As the top comment said it’s easier to move heat around than creating it. Regardless if it’s warmer or colder outside there’s still energy there that we can use.
It’s easier to move your clothes from the laundry basket to the wardrobe, than to go out and buy new clothes (or is it?).
