you feel the heat because electromagnetic waves carry energy so objects that absorb electromagnetic radiation receive energy.
Mostly the heat you feel will be radiation from the flame, which travels in straight lines. Thus it hits the side of the hand nearer the flame.
Air near the flame is heated and rises, thus reaching your hand. This is heat transfer by convection.
Hold your hand NEAR it and see if you can feel any radiated heat. Do not touch it!
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
Heat rises, so it is hotter near the ceiling than near the floor.
Cause heat could be transfered through thin air - it's called radiation.
the heat from the fire! what kind of question is that?

A fire burns fuel to produce heat and gasses. Some of the heat comes off as visible light and some warms the air in and around the fire and this rises with the smoke.However, allot of the heat comes off as infra red radiation - a form of light that you can not see with your eyes, but that you can feel with your skin (as the warmth from the fire).Your skin is always trading heat with its surroundings, your body is always losing heat at a moderate rate to the air touching it. When more heat comes in than goes out, the skin feels warm. So the side of you that faces a fire will feel hot because it is getting more heat than it is losing (because it is absorbing the infra red radiation), while your back surface is shaded from the fire's energy (by your front) and this will be losing more heat than it is receiving and will therefore feel cold.
Near heat? You can go near anything you could go near, or could not, before you were pregnant.
Don't play near any hot items! Don't stick metal in the toaster!
Place your hand near the barrel. If you feel heat, it's hot. If you want to know if it's stolen, check with your local police.
The acronym NEAR stands for Near Earth Asteroid Rendezvous.
