Because the air closer to the heater heats up first. It then gets warmer and less dense and rises to the top of the room, which pushes down the cooler air that is already up at the top. Then that air warms up and rises to the top, pushing the cooler air down.
This creates the Convection Current and that is how the room gets heated : )

it would emit heat in the form of radiation. It will also heat the air which will cause convection. However, these heated gasses will be vented out of the flue so as not to contaminate the air in the room.

Convection, radiation, and conduction are the 3 types of heat transfer... Compare They all transfer heat from a hotter mass to a cooler mass. Contrast Conduction transfers heat through solids. Convection transfers heat through liquids and gases. Radiation transfers heat through electromagnetic waves.
There are 3 main Heat Transfer Mechanisms: Conduction, Convection and Radiation.
Heat can be transfered by convection, radiation or conduction.
Heat is transmitted by conduction, convection, and radiation.
Radiation, Conduction Convection
Yes. Radiation waves given off by the sun, heat the Earth through convection. Convection is the movement of heat transfer through liquids or gases, as seen in this example.
