"Enclosed is the list of wood stoves certified by the United States Environmental Protection Agency (EPA). The EPA Certified Wood
Stoves list contains information about wood stoves or wood heating appliances that have been certified by the EPA along with its
manufacturer name, model name, emission rate (g/hr), heat output (btu/hr), efficiency (actual measured and estimated), and type of
appliance. It also indicates whether the appliance is still being manufactured. An EPA certified wood stove or wood heating
appliance has been independently tested by an accredited laboratory to determine whether it meets the particulate emissions limit of
7.5* grams per hour for non-catalytic wood stoves and 4.1* grams per hour for catalytic wood stoves. All wood heating appliances that
are offered or advertised for sale in the United States are subject to the New Source Performance Standard (NSPS) for New Residential
Wood Heaters under the Clean Air Act and are required to meet these emission limits.
An EPA certified wood heater can be identified by a temporary paper label attached to the front of the wood stove and a permanent
metal label affixed to the back or side of the wood stove (see examples below). If you have questions regarding a particular model line
or manufacturer, please contact Rafael Sanchez at 202-564-7028 or via e-mail at
[email protected]. "
