outside wall
covers reduce airflow past the radiator - since most of the heat is typically produced through convection, the radiators don't work nearly so well
covers also increase heat loss to outdoors through walls

Generated explanation

The illustration shows a cross section of a radiator positioned against an outside wall, with a cover over its top and in front of it. Curved arrows illustrate airflow around the radiator and toward the room. The annotations explain that covers restrict airflow past the radiator, reducing its convective heating performance. They also note that covers increase heat loss to the outdoors through the wall. The floor framing and a portion of the foundation are visible below the assembly.
