Air pollution from wood burning stoves and boilers

Stoves and boilers fuelled by wood contribute significantly to air pollution, which is affected by the complex interplay of several factors.

In Denmark, the number of wood burning stoves and boilers are about 750.000. We have several new types of wood burning stoves that emit fewer pollutants than the older models. Nonetheless, wood burning represents the highest polluting form of heating in Denmark.

How to improve wood burning in Denmark
Stoves and boilers fuelled by wood contribute significantly to air pollution, with harmful particles, poly-aromatic hydrocarbons (PAH), and dioxins. Pollution is affected by the complex interplay of several factors including the type of stove or boiler, chimney design, fuel and patterns of operation. A new statutory order on air pollution from wood stoves and boilers entered into force in January 2018.

Grants for eco-efficient wood burning technologies
In the Danish ecoinnovation programme more than DKK 20 million has been invested into analysis and demonstration of technologies to reduce pollution to the air from wood stoves and boilers, since 2008. The grant scheme's objective is to support development, testing and demonstration of technologies that reduce air pollution from wood burning stoves and boilers in private homes.

Q&A: Testing certificates for wood burners
Testing certificates are necessary for wood burning stoves and central heating boilers running on solid fuel that are sold, transferred or connected after 1 June 2008. You can here find answers to typical questions on testing certificates for wood burning stoves and boilers.
