Frequently asked questions
Is the Foyers Supreme Astra 32 EPA certified?
Yes, the Foyers Supreme Astra 32 is on the EPA's current list of certified wood heaters (certification number 117-18) and meets the 2020 NSPS Step 2 emission limits.
What is the Foyers Supreme Astra 32's emission rate?
The Foyers Supreme Astra 32 is certified at 1.5 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 32 heat?
Roughly 850–1,150 sq ft, estimated from its 29,274 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 32 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 32's certified efficiency is 67% 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.
