Yes, the United States Stove Company US1100E is on the EPA's current list of certified wood heaters (certification number 172-19) and meets the 2020 NSPS Step 2 emission limits.
What is the United States Stove Company US1100E's emission rate?
The United States Stove Company US1100E is certified at 2.4 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 United States Stove Company US1100E heat?
Roughly 1,150–1,600 sq ft, estimated from its 39,683 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 United States Stove Company US1100E 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 United States Stove Company US1100E's certified efficiency is 66% 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.
