Frequently asked questions
Is the Rais A/S Viva 100 L (CA) USA EPA certified?
The Rais A/S Viva 100 L (CA) USA holds EPA certification number 87-17 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 Rais A/S Viva 100 L (CA) USA's emission rate?
The Rais A/S Viva 100 L (CA) USA is certified at 1.1 grams of particulates per hour (tested with crib wood). Real-world emissions depend heavily on fuel moisture and operation — the lab figure assumes seasoned fuel and correct air settings.
How many square feet can the Rais A/S Viva 100 L (CA) USA heat?
Roughly 650–900 sq ft, estimated from its 22,857 BTU/h peak output at 25–35 BTU/h per square foot. Insulation, climate, ceiling height, and floor plan move this figure substantially in both directions.
Does the Rais A/S Viva 100 L (CA) USA 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 Rais A/S Viva 100 L (CA) USA's certified efficiency is 72% 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.
