Osburn 1700-I (insert)

Firebox W × H × D: not listed in our articles
Overall firebox volume: 1.86 ft³
EPA loading volume: 1.44 ft³
Overall heat output range: not listed in our articles
Maximum burn time: not listed in our articles
Efficiency (HHV / LHV): 68% / 73%

Same published firebox: Osburn 1700 and Drolet Escape 1500 (freestanding stoves) publish the same volumes, maximum output and efficiency. We have not compared firebox dimensions, so treat this as a likely, not confirmed, match.

Drolet Escape 1800 (stove)

Firebox W × H × D: 21 × 12 × 16 1/2 in
Overall firebox volume: 2.4 ft³
EPA loading volume: 1.95 ft³
Overall heat output range: 14,200-44,500 Btu/h
Maximum burn time: 8 h
Efficiency (HHV / LHV): 72% / 77%

Same published firebox: No match in our data. Its firebox is larger than the Escape 1500 / Osburn 1700 family.

Enerzone Solution 1.8 (stove)

Firebox W × H × D: not listed in our articles
Overall firebox volume: 1.8 ft³
EPA loading volume: not listed in our articles
Overall heat output range: 10,800-34,000 Btu/h
Maximum burn time: 6 h
Efficiency (HHV / LHV): not listed in our articles

Same published firebox: No match in our data. It shares the 500-1,800 sq ft heating-area claim and 65,000 Btu/h maximum with the Escape 1500 / Osburn 1700, but its output range and burn time differ, so the published figures do not show the same firebox.

What a match does and doesn't mean

Matching published firebox figures suggest the same core design and test data. They do not make two stoves interchangeable: clearances, chimney height, approved installations, warranty and parts can differ. Install each stove only by its own manual and label, and order parts by exact model number. Sources: Drolet and Osburn spec pages and manuals, checked Oct 12, 2026 (see SBI firebox families).

If you are human, leave this field blank.

Why this matters

Drolet and Osburn are both brands of SBI (Stove Builder International), and some of their models publish identical firebox dimensions and test results. Matching numbers suggest the same core design, but not identical stoves: clearances, chimney height, approved installations, warranty and parts can differ. Install each stove only by its own manual.
