What is the Hearthstone Quality Home Heating Products WFP100's emission rate?
The Hearthstone Quality Home Heating Products WFP100 is certified at 1.6 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 Hearthstone Quality Home Heating Products WFP100 heat?
Roughly 1,250–1,700 sq ft, estimated from its 43,000 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 Hearthstone Quality Home Heating Products WFP100 qualify for a federal tax credit?
