A parabolic or concave polished reflector is used in a room heater since the reflector directs the heat produced towards the room effectively.
The reflector collects and discharges the heat into the surrounding room in a highly efficient manner. Without such a reflecting surface, the heat radiating out would fail to adequately heat the room as efficiently.
