Frequently asked questions
Is the Foyers Supreme Astra 24 24SFC (2) EPA certified?
The Foyers Supreme Astra 24 24SFC (2) holds EPA certification number 102-17a but is no longer on the current certified list — it is previously certified, which usually means the model is out of production. Already-installed units are unaffected by that status in most jurisdictions.
What is the Foyers Supreme Astra 24 24SFC (2)'s emission rate?
The Foyers Supreme Astra 24 24SFC (2) is certified at 1.9 grams of particulates per hour (tested with crib wood). Real-world emissions depend heavily on fuel moisture and operation — the lab figure assumes seasoned fuel and correct air settings.
How many square feet can the Foyers Supreme Astra 24 24SFC (2) heat?
Roughly 700–950 sq ft, estimated from its 23,872 BTU/h peak output at 25–35 BTU/h per square foot. Insulation, climate, ceiling height, and floor plan move this figure substantially in both directions.
Does the Foyers Supreme Astra 24 24SFC (2) qualify for a federal tax credit?
