Final New Source Performance Standards (NSPS) for Residential Wood Heaters

EPA has regulated wood stove particulate emissions since 1988. On February 3, 2015, the EPA strengthened its clean air standards for residential wood heaters to make new heaters more efficient and improve air quality. Additionally, these updates create federal air standards for many previously unregulated new wood heaters, including outdoor and indoor wood-fired boilers (also known as hydronic heaters), and indoor wood-burning forced air furnaces. The revisions apply to new heaters ONLY and do not apply to existing wood stoves and other wood heaters installed in peoples’ homes.

The rule becomes effective on Friday, May 15, 2015; however, the final rule also allows retailers to sell woodstoves that meet 1988 requirements and for hydronic heaters through the end of the year.
