In Denmark, the number of wood burning stoves and boilers has increased, partly as a result of higher oil and electricity prices. 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 this country.
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.
Grants for eco-efficient wood burning technologiesIn 2008 and 2009, the Government and the Danish People’s Party set aside DKK 7.1 million for technologies to reduce pollution to the air. 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 burnersTesting 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.
1. Place two or three standard-sized pieces of wood at the bottom.
2. Stack smaller layers until you've filled about ½ of the open area. Make sure there is plenty of air between the layers.
3. Add kindling.
As the fire burns from the top to bottom, it will continue to ignite the wood below.
This way, only a little smoke is created as the fire burns cleanly from the top of the stack.
