Subject: Why do I feel the heat from an electric heater that's ABOVE me?

Sitting underneath an outdoor electric heater (the kind you find outside
of restaurants) my friend asked why we should feel the heat from a heater
that's above us, when heat naturally rises in air. Shouldn't not the hot
air that's been heated by the heater rise up, and thus not make us warm?
Or is it something else which is making us warm instead? Can heat travel
without the need for a medium such as air? 

Thanks!
