List of NYS Certified Outdoor Wood Boiler Models

On March 16, 2015, the U.S. Environmental Protection Agency (EPA) adopted emission standards for new hydronic heaters, including OWBs (40 CFR 60, Subpart QQQQ). As set forth in Section 60.5475 of Subpart QQQQ, OWB models certified by the DEC are deemed to meet EPA's emissions standards. The DEC will maintain the list below through December 31, 2015 after which EPA is expected to maintain the list of hydronic heaters certified for sale in the United States. Only the models listed below may be sold in New York State through December 31, 2015. This list will be updated as additional OWB models are certified for sale in New York.

New York's OWB rule, Part 247 remains in effect until further notice. This includes, but is not limited to, the setback and stack height requirements set forth in Sections 247.5 and 247.6 and the Notice to Buyers requirements set forth in Section 247.9.
