If you have a heat source in one end of the house it may be hard to move that heat to the other end. A fan may do the trick but things like bedroom doors will block that heat. Every corner slows the flow as does distance.
If you look at the design for a forced air heating system, you have a fan pushing into a heating duct. Then you have a return duct coming back to the fan. This causes a negative pressure on the return side and a positive pressure on the supply side.
Think of a garbage truck. You dump the trash in the hopper and the machinery compacts the trash until the truck fills up. Open the back of the truck and you can put trash in the hopper all day long. A fan may do the trick in a smaller home, or one with a straight shot down a short hallway with open doors.
Upper floors can can sometimes be heated with a vent in the floor/ceiling, far from the stairway where the stairway acts as the return duct. The cold air will fall down the stairs while the hot air naturally rises through the vent. The size of the vent controls the heat flow.
