What space does the Enerco Group WS090 suit?
- Its 27,513 BTU/h peak output covers roughly 800–1,100 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 1.16 cu ft firebox puts it in the small/cabin class.
- Rough fuel use: about 2.2 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 Enerco Group WS090 EPA certified?
Yes, the Enerco Group WS090 is on the EPA's current list of certified wood heaters (certification number 342-23) and meets the 2020 NSPS Step 2 emission limits.
What is the Enerco Group WS090's emission rate?
The Enerco Group WS090 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 Enerco Group WS090 heat?
Roughly 800–1,100 sq ft, estimated from its 27,513 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 Enerco Group WS090 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 Enerco Group WS090'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.
