Frequently asked questions

Is the STUV AMERICA STUV 1658IN EPA certified?

Yes, the STUV AMERICA STUV 1658IN is on the EPA's current list of certified wood heaters (certification number 63-16) and meets the 2020 NSPS Step 2 emission limits.

What is the STUV AMERICA STUV 1658IN's emission rate?

The STUV AMERICA STUV 1658IN is certified at 1.47 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 STUV AMERICA STUV 1658IN heat?

Roughly 750–1,100 sq ft, estimated from its 27,015 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 STUV AMERICA STUV 1658IN 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 STUV AMERICA STUV 1658IN's certified efficiency is 71% 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.
