HEATER is placed near the floor because hot air rises up and the room will be heatness will spread even. The density of air depends upon the temperature. ... Hence, heater is placed near the floor because the air currents move upwards so the hot air fills up the whole room.

hey buddy
here ur answer
Cold air falls and warm air rises, which is why hot-air balloons work. The rising hot air from a radiator meets the falling cold air from the window, which would otherwise collect on the floor of theroom. thats why room heater placed on floor...
There are many different types of Ac units. Ceiling mounted, wall mounted and floor mounted units. Despite what many people here have wrote about cold air displacing warm air being the reasoning behind Ac unit positioning, this is not the case.
While it is true that cool air falls and warm air rises, this comes into play more so with ventilation, with many fresh air-in vents located higher up than some return air vents although in many applications and for ease of design they are usually located at the same height.
Design,aesthetics and practicallity play a big part as well as obvious ones such as the load being cooled. In a large open plan office for example ceiling cassette type units will be hung throughout the floor as wall or floor mounted units wouldn't evenly cool (or heat) the conditioned space and many of these units simply wouldn't have the same output required to cool an office as they often have such high heat loads. In a domestic situation it may be more practical to have a wall or floor mounted unit where the heat load is much lower.
Hope that helps to clear up some of the confusion.
