Enerzone Solution 2.3 Size Guide

The Solution 2.3 is the large workhorse of the Enerzone Solution lineup, rated for 500 to 2,100 square feet. It is the right choice when wood is the primary heat source for a 1,500–2,000 sq ft home, when cold climates push past the 1.7's capacity, or when buyers want the longest burn time available in a freestanding non-catalytic Enerzone stove.

• Primary heating for homes between 1,200 and 2,100 sq ft. The 75,000 BTU/h output covers larger spaces than the 1.7 without stepping up to the 3.5.
• Cold-climate primary heating. For homes in Zone 6+ where the 1.7's 65,000 BTU/h would run continuously at high burn, the 2.3 provides headroom.
• Open-plan layouts. The larger firebox and longer burn time keep open floor plans warmer throughout the night and day.
• Households burning 20″ logs. Most cordwood delivery is in 16-20″ rounds. The 2.3 accepts the longer end of standard delivery without resawing.
• Overnight heating focus. 8-hour max burn supports load-at-bedtime, wake-to-coals routines. The longest burn time in the Solution series.
• Manufactured homes 1,500-2,100 sq ft. Mobile home approved with the AC01211 (legs) or AC01336 (pedestal) outside air kit.

• Homes under 1,000 sq ft. The 2.3 will overheat smaller rooms. Choose the Solution 1.4 (250–1,200 sq ft) or Solution 1.7 (500–1,800 sq ft).
• Homes over 2,100 sq ft. Beyond rated capacity. Step up to the Solution 3.5 (1,000–2,700 sq ft, 110,000 BTU/h, blower included).
• Very cold climates with 2,000+ sq ft. The 2.3 may not have enough capacity. Choose the 3.5.
• Buyers who prefer design-forward aesthetics. Consider the Harmony 2.3 — same combustion technology, same heating capacity, heavier construction with premium door overlays and a more refined finish.
• Tight wall installations. The 2.3 requires 16″ side wall clearance — more than the 1.4 or 1.7. Verify your install location can accommodate this.

• Well-insulated, mild climate (Zone 3-4): Upper end of the range — up to 2,100 sq ft achievable.
• Average insulation, moderate climate (Zone 5): Mid-range (1,000-1,800 sq ft).
• Poor insulation or cold climate (Zone 6-7): Lower-to-mid range (800-1,500 sq ft).
• High ceilings (9 ft+): Reduce target by 10-20%.
• Multi-floor homes: Install on the lowest floor. Add 50% of upper-floor square footage to your target.

Verdicts below assume 8-foot ceilings and average insulation. See the notes column for adjustments. The 2.3's strongest fit is the 1,200–2,000 sq ft range with the 1,500–1,800 sq ft point as the operational sweet spot.

• 8-foot ceilings: Use the table values as published.
• 9-foot ceilings: Reduce target by 10%. A 2,000 sq ft home with 9-foot ceilings behaves like a 2,200 sq ft home.
• 10-foot or vaulted: Reduce by 20%. Vaulted living rooms cross into 3.5 territory at smaller square footage than they appear.
• Two-story open layouts: Install on the lower floor. Heat will rise. Add 50% of upper-floor square footage to your target.

• New construction, well insulated: Use table values. Heat retention will be excellent.
• 1980s-2000s average construction: Reduce target by 10-15%.
• Older homes, limited insulation: Reduce by 25%. A 2,000 sq ft poorly insulated farmhouse behaves like a 2,500 sq ft modern home — beyond the 2.3's capacity.
• Drafty cabins or seasonal cottages: Reduce by 25-30%.

All values below are for US installations, sourced from the Enerzone Solution 2.3 installation manual. Canadian clearances differ. Always verify against the certification label affixed to your stove.

Overall dimensions vary by base option: pedestal 25⅝″W × 17″D × 32¾″H; traditional legs 25⅝″W × 19⅛″D × 31¾″H; square legs 25⅝″W × 21¾″D × 30¾″H; round legs 26⅝″W × 21″D × 30⅞″H.

• 16 inches in front of the door opening
• 8 inches on each side of the door opening
• Total floor pad: 36⅜″ width × 53⅛″ depth in the US configuration
• Materials: steel (≥0.015″ thick), grouted ceramic tile on cement board, brick, or any listed floor protection product. No R-factor required.
• Under horizontal connector pipe: floor protection must extend at least 2 inches past each side of the pipe.
• Non-combustible floor (concrete slab): No additional floor protection required.

• Chimney standard: ULC S629 / UL 103 HT (2100°F) factory-built, or masonry chimney with stainless steel 6″ liner.
• Chimney diameter: 6 inches throughout.
• Minimum chimney height: 12 feet total from stove top to chimney top.
• Flue outlet: Top exit only. Offset 9⅝″ from rear, centered side-to-side.
• Connector pipe: 6″ single- or double-wall. Double-wall reduces back wall clearance from 11″ to 6″.
• Chimney height above roof: At least 3 feet above the point of roof penetration, and 2 feet higher than any object within 10 feet horizontally.

The Enerzone Solution 2.3 installation manual confirms mobile home approval (Section 3.1.5 and Section 6.10). At 75,000 BTU/h and 2.4 ft³ firebox capacity, the 2.3 is the largest Enerzone with mobile home approval — making it the right choice for larger double-wide manufactured homes (1,500-2,100 sq ft) that need primary wood heat.

• Outside air intake kit. Required. Two variants depending on the base option:
  • AC01211 — 5″ Ø Fresh Air Intake Kit for stove on legs
  • AC01336 — 5″ Ø Fresh Air Intake Kit for stove on pedestal
• Insulated fresh air intake pipe. HVAC-type meeting ULC S110 or UL 181 Class 0 or Class 1.
• Double-wall connector pipe only. Single-wall is strictly forbidden.
• Factory-built chimney. ULC S629 / UL 103 HT (2100°F) rated.
• Bolt-down to floor. Legs: install a plate on each leg, screw to floor (4 plates total). Pedestal: remove plugs and screw the base directly to the floor.
• Fire screen prohibited. Cannot use the door-open fire screen accessory.
• Installation in sleeping room prohibited. Per HUD compliance.

The Solution 2.3 loads logs east-west — sides of the logs facing the door. The firebox is wider than it is deep, so logs lie left-to-right across the firebox width. This matches the Solution 1.7, 3.5, and Harmony 2.3 (but differs from the 1.4, which loads north-south).

Practical implication: when sourcing firewood, cut to 16-20 inches. The 2.3 accepts the longer end of standard cordwood delivery without resawing. Cordwood mills often default to 20″ rounds, which is the maximum the 2.3 takes.

• Bottom layer: 3 logs east-west on the coal bed, with 1-2″ air space between each log and 1-2″ from the rear firebrick.
• Top layer: 2 logs stacked on top, angled at roughly 20° (for high burn) or flat (for low/overnight burn).
• High burn rate: Largest log on top-front. Air control fully open.
• Low/overnight burn rate: Smallest log on top-back. Run at high burn for 10-15 minutes, then close the air control fully.
• Always maintain air space between logs and around the perimeter for proper secondary combustion.

• Hardwoods for sustained heat and overnight burns: oak, maple, ash, beech, hickory. Highest BTU per cord, slowest burn rate.
• Softwoods for kindling and shoulder seasons: pine, spruce, fir. Use for fire starting and milder days, not as primary fuel.
• Target moisture content: 16-20%. Manufacturer test fuel measured 19-25%; daily use should target the lower end. Use a digital moisture meter.
• Season wood at least one year in a covered, ventilated stack.
• Never burn: wet/green wood (above 25%), treated or painted wood, plywood, garbage, plastics, accelerants, coal. These damage the stove, void the warranty, and produce toxic emissions.
