Is the Windhager Zentralheizung Technik GmbH BioWIN 262 (2) EPA certified?
The Windhager Zentralheizung Technik GmbH BioWIN 262 (2) holds EPA certification number 36HH-20a but is no longer on the current certified list — it is previously certified, which usually means the model is out of production.
