What is the best wood for stove heating – tips
The best fuel for the furnace is considered dry wood from trees predominantly hardwood. Therefore, oak, birch, ash, acacia, or poplar wood is most suitable for the stove. This firewood should be dry and stored for about a year in a ventilated and damp room. Firewood from fruit trees is also suitable for stoves. Apple, pear, and apricot trees have a dense internal structure, and yet burn for a long time and give off enough heat.
The answer to the question of what kind of wood you can’t heat your stove is how much heat the wood gives off when burned, and how much it clogs the chimney.
It is important to remember what kind of wood you can’t use to heat the stove: you can’t use recently cut trees for burning. Such wood will burn very badly and give a lot of smoke, because of its high humidity. Also from them, it is impossible to get a lot of heat, and even lighting them will be very problematic, for this purpose it is necessary to use special means.
Accordingly, in order to know for sure what kind of wood is better to heat the boiler, what kind of wood is better for the stove, and what kind of wood is better to heat the sauna, it is necessary first of all to be guided by the above-mentioned tips.
What firewood is bad – what is better not to heat
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.
