Sustainability and climate protection are issues of paramount importance to us all. Both as manufacturers and as consumers, we are responsible for the conscious selection and use of energy resources. The intelligent and sustainable use of natural, renewable raw materials such as wood as a renewable energy source, in combination with energy-efficient heating systems, contributes to compliance with ambitious climate protection targets and low emissions. The use of firewood saves millions of tons of CO₂ in Europe and makes a significant contribution to reducing greenhouse gases.
Heating with wood has many advantages. Not only is wood a renewable resource, it has a high energy value, a low emission factor and is efficient. It also helps to reduce emissions from wood combustion in households, among other things.
Wood is a renewable resource that only releases as much carbon dioxide (CO₂) when burned as it does during the natural decomposition process in the forest or as much as the tree has absorbed from the atmosphere during its growth.
Firewood has a high energy value. Oak, for example: While it has a residual wood moisture content of approx. 15 - 20%, its calorific value is 4.2 kWh per kilogram.
Firewood has a high energy value. Oak, for example: While it has a residual wood moisture content of around 15-20%, its calorific value is 4.2 kWh per kilogram. Today, 9% of the world's current energy supply (560 EJ) comes from forests, which account for almost 49 EJ. In 2035, the World Bioenergy Association estimates that 13-15% of global energy demand will most likely be covered by wood (72-84 EJ). The abbreviation EJ stands for exajoule and is a unit of measurement for energy.
The impact of air pollution on our health and our environment is so enormous that air pollution is the second biggest environmental problem after climate change. Compared to other energy sources, firewood has a low emission factor with a very low primary energy factor of 0.2.
Wood burning in households with old stoves and open fires contribute significantly more to environmental pollution than modern stoves. Old stoves are part of the problem, new stoves are part of the solution. In the graph, the abbreviation TSP stands for Total Suspended Particles.
Today's technology from Schiedel can dramatically increase stove efficiency by up to 86% while reducing emissions by 2/3 compared to older inefficient stoves. While old and inefficient single stoves and open fires exacerbate the problem, new technologies offer clean and efficient options. We could drastically reduce emissions if consumers do both: replace old appliances and use only the highest quality dry wood.
30% of annual forest growth remains in the forest. The European forest area is increasing by the area of a soccer pitch every minute, so the potential for carbon capture will increase in the coming decades.
Sustainable use of the entire tree: Wood as a raw material is not only a great source of energy and heat, but is also suitable for use in building structures or for the manufacture of wooden furniture.
In addition to energy saving, the EU is focusing on renewable energies such as biomass and wood in particular. Our energy systems must become free of fossil fuels. The EU plans to expand renewable energies to at least 30% by 2030.
Hardwood is more suitable for use in a wood-burning stove than softwood. Softwood has a high resin content and therefore a shorter burning time. These four types of wood are ideal for combustion - beech, oak, birch and spruce.
Make sure that the firewood comes from regional forests and from sustainable forestry. In this way, you are supporting environmental protection and acting sustainably. The best firewood has been dried for over a year and has a residual moisture content of 15-20%. As damp/fresh firewood is heavier than well-seasoned firewood, you also get less wood for your money.
Choosing the right firewood is crucial for its calorific value. The size of the logs should match the size of the stove. For most wood-burning stoves, this means a log length of between 25 and 30 cm, while the circumference should not exceed 25 cm.
