Frequently asked questions
Is the 509 Fabrications zzzzz EPA certified?
The 509 Fabrications zzzzz 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.
Does the 509 Fabrications zzzzz 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 509 Fabrications zzzzz's certified efficiency is 12% 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.
