Physics aside, the most expensive areas to heat are the coldest locations. Cold air has more weight than hot air, so it is usually finds its way to the lowest spot "continually fighting against the hot air". With wood stoves, it is a good idea to place your fan on the floor at the coldest area of your dwelling, and blow the air toward the stove.Removing the lower layer of heavy air, makes it much easier for the warmer air to sink. So having the lowest ares being the source of heat, makes sense to me.
