The usual is a wall model mounted high on the wall. Then the interior will also better draw in the warm heat that has collected up near the roof.
Floor model is recommended if there are few options on the wall, if you do not want it on the wall or if you have cold floors (basement?). Then you will be able to get exhaust over the floor/low.
Some choose to mount wall models low, but we do not recommend this. In that case, it is important not to angle the heat too far down, especially if you have a floor that cannot withstand the heat.
For information, the floor models do not deliver as much heat as the wall models, but still cost more.
