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? [@[email protected]](h (social.graves.cl)

it has an LED and fan

If you can't see the light or hear the fan from outside the room you are using the heater in, that energy has also become heat.

Yeah, but than, does it really makes a sound?

At the expense of ruining the joke, yes it does. Anyone inside the room would be able to hear the sound.

And if no one is in the room to hear if there is a sound or not, you might want to turn the heater off to conserve energy.
