What space does the MF Fire NOVA suit?
- Its 25,224 BTU/h peak output covers roughly 700–1,000 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 1.63 cu ft firebox puts it in the mid-size home class.
- Rough fuel use: about 1.7 cords per season at the midpoint of its output range (8 burn-hours/day, 150-day season, 22 MMBtu/cord — see methodology).
- Certified burning Crib Wood .

Frequently asked questions
Is the MF Fire NOVA EPA certified?
The MF Fire NOVA holds EPA certification number 138-18 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 MF Fire NOVA's emission rate?
The MF Fire NOVA is certified at 1.9 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 MF Fire NOVA heat?
Roughly 700–1,000 sq ft, estimated from its 25,224 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 MF Fire NOVA 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 MF Fire NOVA's certified efficiency is 71% 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.
