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
Heating vents should be placed near or on the floor in a room because heat travels up not down.
Heat rises. So, in areas with long winters, the vents typically are in the floor. But it depends on the construction of the house, where the heating unit is installed and what type it is, etc. So, no easy answer. Ceiling fans are helpful in keeping air circulating, moving warmer air from the top of the room downward which helps even out the temps from floor to ceiling.
The precautions are -wire gauze should be placed in between the flask and tripod stand while heating process.clamp the flask gently in the retort stand.
To save on heating costs
There should be a small slide switch on the fan. Turn it off and let it stop then move the slide switch then restart it and it should go in the other direction. If you are smart enough to ask a question on answers.com you should be smart enough to change the direction of a ceiling fan!
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 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.
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.
should be on floor.
A ceiling fan should blow downwards when used with cooling, upward when used with heating.
Having the ceiling fan blow upwards will circulate the heat through the entire room.
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.

Based on the height of the ceiling the lights can be placed at half the distance. For a ceiling of 14 feet, the lights should be at 7 feet.
