This is due tobuoyancy. Think about a hot air balloon as an example. Warm air has greater buoyancy than cooler air and will rise. Conversely, cold air will sink when introduced to a warmer atmosphere and this is why you see cooling vents placed in the ceiling.
on the floor on the floor
Heating vents should be placed near or on the floor in a room because heat travels up not down.
Heating vents should be placed on or near the floor because heat rises. In rising, it will warm the air of the room. If the heating vent were near the ceiling, the room would stay chilly, even though heat was being poured into it.
Heating vents should be located near the floor since hot air rises. If the heating vents are located near the ceiling the heat would stay there and not warm the room.

Ceiling. Cold air fails
It would be better to place the heating vent near the floor because the heat will travel up and down, so that way the room would be heated evenly. If you place it near the ceiling, the heat would not heat the floor that well, since the heating vent sucks back in the heat
A thermostat for heating or a thermometer for air temperature is typically placed on an inside wall (not outside wall), and away from heating vents or direct sunlight.
