This is true, but does not tell the complete story. If you think of "efficiency" in terms of making a room feel warmer for less input electricity, I think you can improve things by getting a heater that includes a fan. Most of my home is heated by electric baseboard or in-wall heaters. The in-wall heaters all have built-in fans. Those rooms get warm much quicker, and stay warmer, then the room with the two 4-foot baseboard heaters that don't have fans. I wish I could find replacements that do have fans.
