Frequently asked questions
Is the Steel Tech G Series G200-2/G200s EPA certified?
The Steel Tech G Series G200-2/G200s holds EPA certification number n/a 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.

The Steel Tech G Series G200-2/G200s is certified at 1.7 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.
Does the Steel Tech G Series G200-2/G200s 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.
