Only that they are maximum 2 kW and a gas one is about 11 kW. Would they

But an electric one would be a much greater % of energy converted to IR
whereas a gas one would (I presume)have a wast majority of energy
converted to "ordinairy" ? heat.

I am just guessing at a logical explanation.
Hoever there is no reason it shouldn't work outdoors as IR won't get
"blown away" by the wind etc.
