Latest on the EPA’s NSPS affecting Hearth Products

In February 2015, the EPA published its final rule regarding the New Source Performance Standards (NSPS) for Residential Wood Heaters. The effective date of the new rule is May of 2020 — manufacturers of wood stoves, pellet-burning room heaters, single burn rate stoves and hydronic heaters will not be allowed to produce new appliances unless they meet the Step 2 requirements.

Once your product has proven to be in compliance, your product is eligible to bear one of Intertek's recognized certification marks. By utilizing the Building Products Certification Services, you are showing your commitment to product safety and quality to inspectors, builders, and end-users. Additionally, Intertek partners with customers to develop ongoing compliance testing programs to ensure that new product components do not compromise the quality and performance of your product.
