Regulatory Actions for Residential Wood Heaters

EPA's New Source Performance Standards (NSPS) for residential wood heaters fall under Section 111 of the Clean Air Act. The standards govern the manufacture and sale of new residential wood heating devices and do not apply to existing wood stoves and other wood heaters installed in peoples' homes.

On February 3, 2015, EPA strengthened its New Source Performance Standards (NSPS) for residential wood heaters to make new heaters significantly cleaner.

1988 NSPS for Residential Wood Heaters

On February 26, 1988, EPA issued New Source Performance Standards (NSPS) that govern the manufacture and sale of new wood stoves, and certain wood burning fireplace inserts built after 1988.

The 1988 standards were amended on November 24, 1998, to prohibit the sale of wood heaters that had their original certification revoked due to an invalid certification test. This action did not affect wood heaters that had already been sold to consumers.
