The report presents the results of a two-year study that monitored smoke emissions of wood stoves in 68 homes near Glens Falls, New York and Waterbury, Vermont, to determine whether new wood stove technologies proved to be as effective in reducing smoke emissions when used in the home as laboratory tests had showed. The monitoring found that the new stoves failed to reduce smoke emissions to the extent found in the laboratory. However, they did consume less wood than conventional stoves. The study found that, in the home, wood stove emissions varied greatly for the exact same model stove; however, some new wood stove models did reduce smoke emissions. Non-catalytic low-emission stoves produced, on average, less smoke than conventional stoves; catalytic stoves, as a group, showed a statistically insignificant reduction in smoke emissions compared to conventional stoves. Firebox size proved to be a major factor in determining smoke emissions from all stoves; generally, the larger the firebox, the higher the emission rate.
