Question

Why is room heater placed near the floor and an air conditioner near the ceiling? ​

Answer 1

Answer:

The heater is placed near the floor because the air currents move upwards so the hot air fills up the whole room. Whereas, an air conditioner is placed near the ceiling because the cold breeze tends to settle down. ... So it is placed near the ceiling so that the whole room cools down.

Answer 2

Answer:

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.
