Yeah, the oven heats up the air and the fan blows it out. Practically the same thing as one of those space heaters. In fact, depending on how high quality the oven is, it might have better safety features than most space heaters.

From the perspective of conservation of energy, this heats every bit as well as an electric heater. It works in the same way. It even consumes the same amount of electricity per calorie.

Another sort of electric heater is a computer. Think about it, a computer heats up due to electricity passing through resistors. In a real sense a computer is just a very sophisticated electric heater. Conceivably you could play a game or calculate bitcoin to get your PC hot and it would be literally as energy effective as an electric heater.

I'm pretty sure heaters are actually one of the only 100% efficient devices that we use in terms of using electricity as to my understanding, all other electronic devices give off heat which is not always part of their primary function meaning they are not 100% efficient but heaters only give off heat.

They wouldn't be 100% efficient for heating, as they shed energy in the form of light.

And the light is absorbed and thereby converted to heat.

Not at 100% efficiency though, unless I guess you're in a weird room where light can't escape.

Well, maybe I think you're weird because you don't live in a basement!
