Is the Windhager Zentralheizung Technik GmbH BioWIN 212 EPA certified?
The Windhager Zentralheizung Technik GmbH BioWIN 212 holds EPA certification number 39HH-20a 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.

No — the federal 25C credit for biomass stoves was terminated for property placed in service after December 31, 2025. The Windhager Zentralheizung Technik GmbH BioWIN 212's certified efficiency is 58% HHV, which did not meet the credit's ≥75% HHV threshold while it existed.
