There's convective and radiative heat, while the first one needs some medium to transmit energy (air...), the second one simply beams it onto you

    3 mechanisms for heat transfer: conduction (heat moves from one bit of matter to another when they are touching), convection (in a fluid, hot matter move about), and radiation (pure heat, only form that goes through a vacuum, this is just like lower frequency light that we can't see).
