  1. In regards to the oil filled heater, it is more efficient, because you keep your temperature delta lower. In your example of the 50% duty cycle, you didn't take into account that the standard heater is going to create a higher temperature when it turns on, until it reaches the set temperature and shuts off, and then the room will cool down until the heater turns back on, and if you graph it you will see the temperature going quite a bit above the set temperature, and then dropping below, and when the temperature goes higher, it loses more out the walls and ceiling and such. With the oil filled heater, it stays at a much more consistent temperature, reducing the peaks, and so not pushing as much heat out of the room.

  2. I don't know how much you have actually used different types of space heaters, but there is a big difference between them. The small ones that say small room usually have a very tight air flow pattern, and so are ideal for heating one area of a room, such as blowing directly on you. Because of the fan and the directed air flow, they are better for warming up a small area than the large format which mostly sends the heat upwards, and you have to heat the whole area in order to feel warm. So if you are looking for a heater to warm a small area, get the one rated for a small room.
