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 know how you turn on an electric heater and the filament begins to glow? That is energy being converted to light, so not 100% efficient.
Doesn’t the light turn into heat anyway as soon as it’s absorbed?
