- The 2.12 cu ft firebox puts it in the mid-size home class.
- Rough fuel use: about 1.9 cords per season at the midpoint of its output range (8 burn-hours/day, 150-day season, 22 MMBtu/cord — see methodology).

Frequently asked questions
Is the Innovative Hearth Products S210AGL EPA certified?
The Innovative Hearth Products S210AGL holds EPA certification number 200-19 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 Innovative Hearth Products S210AGL's emission rate?
The Innovative Hearth Products S210AGL is certified at 1.5 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 Innovative Hearth Products S210AGL heat?
Roughly 1,100–1,500 sq ft, estimated from its 37,857 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 Innovative Hearth Products S210AGL 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 Innovative Hearth Products S210AGL'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.
