They are in front of the elevators at an outdoor multi story parking garage around my area. That's all I wanted to share, thanks.

It really depends on the use case. These “shoot” the heat directly onto the surface, instead of heating the air and pushing that air in a direction.
If you’re standing under them for long periods of time, they’ll (generally) be a better option in a cold environment, since it’s directly heating you instead of the air.
But if you’re just walking under them for a moment, or if it is meant to be a kind of “heat boundary”, heated air is going to be the better option.
Considering placement, I'm willing to bet these are intended for heating the walkway, not people. People with snowy shoes standing around waiting for an elevator are making puddles, and without a heater, the puddles will turn to ice right on the one part of the parking garage that nearly everyone will be walking on.
Oh that’s a really good point I hadn’t thought of. That would make sense.
