Frequently asked questions
Is the Foyers Supreme Astra Duo 38 EPA certified?
The Foyers Supreme Astra Duo 38 holds EPA certification number 276-20 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 Duo 38's emission rate?
The Foyers Supreme Astra Duo 38 is certified at 2.2 grams of particulates per hour (tested with cord 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 Duo 38 heat?
Roughly 1,750–2,450 sq ft, estimated from its 61,231 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 Duo 38 qualify for a federal tax credit?
No — the federal 25C credit for biomass stoves was terminated for property placed in service after December 31, 2025. The Foyers Supreme Astra Duo 38's certified efficiency is 65% HHV, which did not meet the credit's ≥75% HHV threshold while it existed. State and local incentive programs may still apply — check your state energy office and air district.
