How it compares
Against all 109 new pellet stoves, from the EPA's lab tests. Longer bar = better.
Source: EPA certification record 4885, checked Nov 1, 2026. Smoke compared as a share of each stove's legal limit, since stoves tested on real cordwood get a higher limit.

Other questions
What size chimney liner does it need?
Match the liner to the flue collar size in the ComfortBilt HP22N owner's manual, and have a certified installer confirm it fits your chimney.
It's non-catalytic. What does that mean?
There's no catalytic combustor, so no combustor part to replace down the road.
What do these numbers mean?
The EPA tests every new stove before it can be sold. "Heat" is the most heat it put out in the test. "Clean burning" is smoke per hour. "Heat from each log" is the share of the wood's energy that reaches your room. Firebox size tells you how much wood it holds, which drives how long it burns.
