Reply to comment by hacknix in Does oil filled heater takes much longer than the fan heater? by Substantial-Elk-1259

The book may say but I tell you from experience that if you cool off the heater too much it isn't going to throw heat anywhere near as much as if you let it stay hot.

But you can change the efficiency by modifying airflow.

Possibly. What OP is probably noticing is that if more heat is transferred by convection, there may be less heat transferred as radiant heat, so if you sit or stand in front of it, you maybe won't feel the warmth so much. The heat is still transferred, but using a different method. So, the room may be warmed more efficiently with more air flow, but, for example, your legs, if you are sitting facing it, may not be. So it depends what you want. Are you more interested in warming the room, or your person?
