Why heating devices are always placed under a window? If the windows are not properly insulated, the heat doesn’t just go out the window?

The natural convection mentioned by u/saywherefore applies to any heating device, the unpleasant draft is intensified greatly if a flame heater like a gas or wood burning heater is used. No curtains on the window please!
The flames consume air and the air will be drawn from the nearest fresh air source, quite a strong air current can be felt this way. If the fresh air is coming from under the door across the room the whole room can feel chilly.
Placing the flame heater under the window and **opening the window** just a tiny bit draws fresh air for the flames to consume from the window and so prevents drafts from other sources and also preserves the natural convection present with any heater. Also improves air quality in the room by insuring that the room air isn’t consumed by the flame heater.
