Frequently asked questions
Is the Maine Energy Systems PE/PES 12-20 EPA certified?
The Maine Energy Systems PE/PES 12-20 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.
What is the Maine Energy Systems PE/PES 12-20's emission rate?
The Maine Energy Systems PE/PES 12-20 is certified at 0.7 grams of particulates per hour (tested with wood pellets). Real-world emissions depend heavily on fuel moisture and operation — the lab figure assumes seasoned fuel and correct air settings.
Does the Maine Energy Systems PE/PES 12-20 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 Maine Energy Systems PE/PES 12-20's certified efficiency is 75% HHV, which met 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.
