EPA-certified wood stove
Also called: EPA-certified stove · certified wood stove
A wood stove or insert tested to meet EPA's smoke emission limits; it burns cleaner and more efficiently.
What it means
Since 2020, new wood heaters sold in the US must emit no more than 2.0 grams of particles an hour when tested with crib wood, or 2.5 grams with cord wood. Certified models carry a metal EPA label, and some rebates require certification.
Why it matters in an audit
Certification is the first thing to check on a wood stove: older uncertified models smoke more and burn more wood for the same heat.
Typical numbers
