Blaze King Sirocco 25: is it worth buying?
Wood stove insert by Blaze King Industries. Also sold as SC25, Insert, Ashford 25, AF25, Boxer 24, BX24 and more.
A good pick if you want very little smoke and getting the most out of your wood.
The catch: less heat than most.
How it compares
Against all 156 new wood stoves, from the EPA's lab tests. Longer bar = better.
Source: EPA certification record 5181, 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 Blaze King Sirocco 25 owner's manual, and have a certified installer confirm it fits your chimney.
It's catalytic. What does that mean?
It has a catalytic combustor, a honeycomb part that helps burn off smoke. It wears out over time and needs replacing, so ask the dealer what a new one costs.
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.
