उत्तर
Room heaters are fitted near the floor because this allows the hot air near the heater to rise up and warm the entire room.
The air conditioners are fitted near the ceiling so that the cold air from the AC takes the place of hot air rising up from the bottom. In this way, the entire room gets cooled.
