A convection baseboard heats the air along the bottom of a wall, usually under a window, and lets it rise into the room with no fan and no noise. Most give about 250 W per foot of length, so a 4 ft heater is about 1,000 W. Short, high-output linear convectors fit the same heat into less wall. Almost all of them need a line-voltage wall thermostat or a built-in thermostat kit sold separately, so add that to the price.
