All resistive electric heaters are 100% efficient. Even the fan warms the air with as much energy as you put in. The oil filled ones do feel more comfortable since they have more of a radiative heat, but they won't save you any money if you use them to heat the room to the same temp.

Exactly. Because "inefficiency" in any device is just energy that got converted to heat, which is what you want anyways in this case. I don't worry much about leaving my indoor lights on in winter for much the same reason, though some of that energy does escape out the window as light.
