Frequently asked questions
Is the STUV AMERICA STÛV 1678IN EPA certified?
Yes, the STUV AMERICA STÛV 1678IN is on the EPA's current list of certified wood heaters (certification number 408-26) and meets the 2020 NSPS Step 2 emission limits.
What is the STUV AMERICA STÛV 1678IN's emission rate?
The STUV AMERICA STÛV 1678IN is certified at 1.8 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 STÛV 1678IN heat?
Roughly 750–1,100 sq ft, estimated from its 27,092 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 STÛV 1678IN 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 STÛV 1678IN'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.
