Frequently asked questions
Is the Hearth and Home Technologies Quadra-Fire Pioneer-II-C EPA certified?
The Hearth and Home Technologies Quadra-Fire Pioneer-II-C holds EPA certification number 229-19 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 Hearth and Home Technologies Quadra-Fire Pioneer-II-C's emission rate?
The Hearth and Home Technologies Quadra-Fire Pioneer-II-C is certified at 1.8 grams of particulates per hour (tested with cord 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 Hearth and Home Technologies Quadra-Fire Pioneer-II-C heat?
Roughly 1,400–1,950 sq ft, estimated from its 48,212 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 Hearth and Home Technologies Quadra-Fire Pioneer-II-C 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 Hearth and Home Technologies Quadra-Fire Pioneer-II-C's certified efficiency is 70% 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.
