Frequently asked questions
Is the Hearth and Home Technologies Quadra-Fire Pioneer - III EPA certified?
The Hearth and Home Technologies Quadra-Fire Pioneer - III holds EPA certification number 190-19 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 - III's emission rate?
The Hearth and Home Technologies Quadra-Fire Pioneer - III is certified at 2 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 - III heat?
Roughly 2,100–2,900 sq ft, estimated from its 72,724 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 - III qualify for a federal tax credit?
