The cleanest ÖkoFEN pellet heating system ever!
The cleanest ÖkoFEN pellet boiler ever
Tested by TÜV Austria
The amount of particulate matter leaving the high-efficient pellet heating system can hardly be measured. This has a high impact to the environmental situation worldwide. A practice 9-hour load cycle test carried out by TÜV Austria officially confirms the excellent values and unique effect of the new technology.
Practice load cycle test
The 9h load cycle test is a dynamic cycle test which represents real operation values of a heating system in our latitudes. This test is absolutely not comparable with other static test reports.
In the smallest output range, the emission test includes one start and two stops of the boiler.
