For example, it is European determined that appliances that are sold new must comply with rules in the field of safety, emissions and efficiency. The higher the efficiency of a wood-burning stove, the cleaner the combustion. And nationwide there are technical building rules for wood-burning stoves; requirements are set for the extraction of smoke and the supply of combustion air. “We believe that air pollution and nuisance caused by burning wood should be reduced, and we are working on that,” explains a spokesperson for State Secretary Heijnen. “We do this, among other things, by setting strict requirements for stoves, good information, the heating alert, and with pilots with wood smoke-free neighbourhoods. Among other things, in the municipality of Utrecht.”
