Firewood from conifers (pine, spruce, cedar) has many significant disadvantages: they burn quickly, they have low calorific value, and they contain a lot of resin. Such firewood sparks while burning on the stove, emit an unpleasant characteristic smell and smoke strongly.

It is also necessary to know what kind of wood clogs the chimney. Birch firewood has a huge disadvantage: there is a lot of tar in the wood, which smokes very strongly when burned. This soot later settles on the walls of the chimney and clogs it for several months.

Also wood from poplar-type trees is not very suitable for heating because of the high level of consumption: it burns quickly while releasing little heat and sparks a lot.
