What space does the Stove Builder International 1.7R Series: Blackcomb II suit?
- Its 52,200 BTU/h peak output covers roughly 1,500–2,100 sq ft at the 25–35 BTU/h-per-square-foot rule of thumb — see the sizing calculator to adjust for your insulation and climate.
- The 1.86 cu ft firebox puts it in the mid-size home class.
- Rough fuel use: about 2.5 cords per season at the midpoint of its output range (8 burn-hours/day, 150-day season, 22 MMBtu/cord — see methodology).
- Certified burning Cord Wood — the test fuel closest to real-world firewood.

Frequently asked questions
Is the Stove Builder International 1.7R Series: Blackcomb II EPA certified?
Yes, the Stove Builder International 1.7R Series: Blackcomb II is on the EPA's current list of certified wood heaters (certification number 132-18) and meets the 2020 NSPS Step 2 emission limits.
What is the Stove Builder International 1.7R Series: Blackcomb II's emission rate?
The Stove Builder International 1.7R Series: Blackcomb II is certified at 2.4 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 Stove Builder International 1.7R Series: Blackcomb II heat?
Roughly 1,500–2,100 sq ft, estimated from its 52,200 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 Stove Builder International 1.7R Series: Blackcomb II 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 Stove Builder International 1.7R Series: Blackcomb II's certified efficiency is 68% 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.
