What's an "inefficient electric heater"? Is that a device that generates more light than heat?

Surely all the energy you put into any machine is eventually going to turn into heat? Hmm - perhaps there are heaters that generate heat mechanically, and the resulting losses are sonic.

There are electric heat pumps which move heat from the ground into your space which use drastically less energy than electric heaters that convert electricity into heat directly.

Sure; but that's because a heat pump has the potential to be > 100% "efficient" (which isn't real efficiency, in the thermodynamic sense).
