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

Only in the sense of releasing heat into the surrounding environment. But for instance, an electric boiler is not 100% efficient because not all of the heat goes to the water. The heat that doesn’t go to the intended recipient of the heat is treated as loss.
