Using these heaters to heat a room is probably one of the most expensive ways to heat a room and one of the least efficient ways to use electricity for heat.
If I were to use one of these heaters it would be to warm me while sitting in a chair. I would probably opt for an infrared heater. But for me, if I'm chilled, a blanket works great, sometimes too well as I'll fall asleep. If a blanket weren't enough, I'd get a heated throw blanket. They use much less electricity and focus the heat much better.
An electric fan is a heat source. It also imparts mechanical energy to the air it moves, that energy is converted to heat eventually and it all happens in the room for a small heater like we are talking about. In reality most of the 1500 watt heaters that use a fan have a small induction motor that probably uses a few watts of electricity. But that is still a source of heat to a room.
Thermodynamics, not just a good idea, it's the law.

But the law does not state that it will be focused heat.
A warm ceiling is nice... but not really what anyone is looking for.
