They're radiant (think beam of light), not convective, so their heat travels in a straight line. They're highly effective actually, which is why you'll see them in many higher-end public areas.

You'll also find radiant heaters under canopies of office buildings and in front of hotels in colder climates. They work extremely well. When I'm in NYC on business, I know just about every canopy/overhang w/radiant heaters on them and make it a point to stop by them on my walks to/from work when it's cold out. Even at 12F, they still work.
