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)

Not quite. Some is lost in magnetic flux and mechanical deformation. But that is a VERY small about.

Do those not end up as heat later down the line as well?

Yes, but magnetic flux causes radio waves and there isn't a guarantee these will turn into heat in the space you are heating.

That's an interesting point about radio emissions leaving the heated space.
