Additionally, don't forget to keep your fire in a "..will burn for a long time" state because it will lose heating power when fuel begins to run low. At its final stages, it may very well be so weak that items inside will cool faster than they heat.
To fill up the campfire to maximum, you have to fuel it with 20 kg of any wood. Burning any more wood will then make it wasted and unusable in fuelling.
