Vedeldning

Vedeldning refers to the combustion of wood as a source of heat and energy in homes and industries. It encompasses the use of logs, wood chips, and pellets in devices such as fireplaces, wood stoves, and wood-fired boilers. Historically a common heating method in many parts of Europe, vedeldning remains widespread in rural areas and as a supplementary heat source.

Fuel and moisture content are central to vedeldning. Dry, seasoned wood with a moisture content around 15–25 percent burns more efficiently and with less smoke than green wood. Wood species differ in energy content and smoke production. Pellets and briquettes offer uniform fuel and can achieve high efficiency when burned in certified appliances.

Technology and operation vary with device type. Modern wood stoves and boilers feature insulated combustion chambers, secondary air intake, and sometimes catalytic or non-catalytic aftertreatment. Proper installation, including an adequately sized chimney and good ventilation, is essential. Regular maintenance, such as chimney cleaning and appropriate ash disposal, supports safe and efficient operation.

Efficiency, emissions, and regulation are important considerations. Efficiency ranges widely by appliance and use; high-efficiency models with proper operation reduce emissions of particulates and carbon monoxide. Wood burning can contribute to local air pollution, particularly during cold starts or when using damp wood. Many countries regulate emissions, require certified equipment, and set standards for installation and operation.

Safety and sustainability are integral to vedeldning. Responsible forest management and sustainable harvest practices underpin its renewable character. Safety measures include installation by professionals, proper chimney clearance, functioning carbon monoxide detectors, and adherence to local laws and guidance.
