A 2.4 ft³ non-catalytic medium-large freestanding wood stove — the larger step-up in the Enerzone Solution line. EPA 2020 cordwood certified at 72% HHV efficiency and 2.3 g/hr emissions, with a 20-inch maximum east-west log capacity, up to 2,100 sq ft of heating area, an 8-hour maximum burn time, mobile-home approval, 75,000 BTU/hr maximum output, an optional 130 CFM variable-speed blower, and a required base selection at order (three leg styles in Black or Brushed Nickel, or a pedestal).
Who this is for
Right buyer
Owners of medium-to-larger homes, well-insulated open-plan two-story spaces, or one stove serving as primary winter heat across 1,200–1,800 sq ft of conditioned space, with reasonable insulation and access to seasoned hardwood at 15–20% moisture content. Mobile-home and manufactured-home owners — this stove is certified for mobile-home installation with the required fresh-air intake kit and insulated intake pipe.
Buyers stepping up from the medium-stove platform (Solution 1.7) who want a meaningful firebox jump, longer 20-inch logs, and longer burn cycles. The Solution 2.3 covers heating areas from 500 sq ft on the low end up to 2,100 sq ft on the manufacturer's high end, with a tested output band of 14,200–44,500 BTU/hr — a usable range for both shoulder seasons and cold-snap loads.
Buyers who want east-west loading and the wider 17 1/2-inch door opening that comes with it. The Solution 2.3 is built around a wider-than-it-is-deep firebox; logs go in across the width, sides visible from the door. Per the manual, the firebox also accepts north-south loading thanks to the 16 1/2" depth — useful for packed overnight loads.
Buyers who want configurable styling. The Solution 2.3 ships with a choice of seven base configurations: three leg styles (round, traditional, flared) in either Black or Brushed Nickel, or a pedestal — letting the stove sit anywhere from low-slung to elevated depending on the room. The arched cast-iron door and engraved-groove side panels deliver a refined-but-not-ornate look.
Wrong buyer
Not for buyers heating under 1,000 sq ft. The Solution 2.3 is meaningfully larger than the Solution 1.4 or 1.7; in a small room it will overheat at almost any meaningful burn rate. If you're heating a small space, look at the smaller Solution 1.4 or 1.7 instead.
Not for buyers expecting 10+ hour overnight burns. The 8-hour manufacturer maximum is achievable on a packed load of dense hardwood with the air shut down hard, but useful heat from a packed load is realistically 6–7 hours. For longer burns, step up to a 3.0+ ft³ firebox or to a catalytic stove with a real low-output mode.
Not for buyers wanting heavy decorative cast-iron styling. The Solution 2.3 has clean lines and refined Enerzone detailing, but it is not an ornate cast-iron showpiece. Buyers who want furniture-grade cast iron should look at premium-tier alternatives.
At a glance
Where it can go
The Solution 2.3 is approved for installation in residential homes, cabins, sunrooms, and mobile or manufactured homes (with the required fresh-air intake kit and insulated intake pipe). It is not approved for installation in factory-built (prefab) metal fireplaces or in any outdoor or unconditioned space.
Clearances to combustibles — USA
Clearances to combustibles — Canada
The certification label on the back of the stove always overrides clearance figures published in any other media. Confirm the binding clearance figures with your installer before purchase. The install manual specifies additional reduced clearances available with approved wall heat-shield construction; review with your installer.
Floor protection
For the Solution 2.3, the manual specifies no R-factor required for floor protection — only a continuous, non-combustible material. Approved materials include steel of at least 0.015" thickness, ceramic tiles sealed together with grout (over a continuous non-combustible sheet beneath), cement board, brick, or any other approved or listed material suited for floor protection. Tile alone is not sufficient — a continuous non-combustible sheet beneath the tile is required. No floor protection is required if the stove is installed on a non-combustible floor (concrete slab, for example).
Chimney and venting
The Solution 2.3 requires a 6-inch chimney flue system. New factory-built chimney systems must comply with UL 103 HT (USA) or ULC S629 (Canada) and be suitable for solid fuel. The stove may also be connected to a code-compliant masonry chimney, provided the chimney has either a clay liner or a suitably listed stainless-steel liner at 6-inch diameter and the application is verified by a qualified installer.
The minimum chimney height is 12 feet, subject to installer verification, certification label, draft conditions, and local code. The chimney must extend at least 3 feet above the highest point of contact with the roof and at least 2 feet above any roof line or obstacle within 10 feet horizontally.
For mobile-home installations, single-wall pipe is strictly forbidden — only double-wall pipe is permitted, and a fresh-air intake kit with insulated intake pipe is required. The fresh-air intake pipe (HVAC type) must meet ULC S110 or UL 181 class 0 or class 1.
Outside air
An optional fresh-air intake kit is available for code jurisdictions requiring outside combustion air, for tight new-construction homes with mechanical ventilation, and is required for mobile-home installations. Two different kits are offered depending on base configuration — one for legs versions and one for the pedestal version. Confirm the correct kit for the chosen base. A smoke detector and carbon monoxide detector are required in the room where the stove is installed.
Code compliance
Code compliance for any specific installation is determined by the local Authority Having Jurisdiction. Manufacturer listings cover what the stove is approved for; the AHJ approves what is permitted at your address. A WETT (Canada), NFI, or CSIA (USA) certified installer is strongly recommended and frequently required by code, permit, or insurance. Confirm local requirements before purchasing — particularly in EPA non-attainment counties and in HOA jurisdictions where new wood-burning installs may be restricted.

How it actually performs
The 75,000 BTU/hr maximum is a peak rating, transient, achieved on dry cordwood at high loading density and short reload intervals. The figure that matters for daily life is the sustained output across a full burn cycle, which lands in the 14,200–44,500 BTU/hr band per the CSA B415.1-10 stack-loss method — a usable range that covers shoulder-season heating on the low end and serious cold-snap output on the high end.
A realistic burn cycle from a packed load of well-seasoned hardwood produces a fast 30–45 minute warm-up, 2–3 hours of strong sustained heat, then a gradual decline over the next 3–4 hours with a coal bed remaining. Total useful heat from one full pack is realistically 6–7 hours, occasionally approaching the 8-hour manufacturer maximum with dense hardwood, mild weather, and a packed coal bed. Reload onto coals when heat output falls off and the cycle restarts.
The 20-inch maximum log capacity is the meaningful differentiator vs the smaller Solution 1.7 (18 in). Most firewood suppliers cut to 16 inches as standard, but 20-inch capacity gives real margin — a buyer with access to longer-cut wood gets four extra inches of fuel per log without juggling. East-west loading is the default; the firebox depth of 16 1/2" also accepts north-south loading for packed overnight cycles per the manual.
The 130 CFM optional blower is a meaningful step up from the smaller stoves in the catalog. With the blower installed, the variable-speed control lets you dial CFM up or down, and the thermodisc senses stove temperature and runs the blower automatically when the stove is hot. Without the blower, heat distribution relies on radiant heat and natural convection; the back heat shield helps push heat off the rear of the stove into the room. For one-room or single-zone use, radiant and natural convection are often enough. For distribution into adjacent rooms or open-plan spaces, the blower meaningfully helps.
Air-wash glass stays largely clear during proper hot burns at moderate-to-high air settings. At low burn rates with marginally seasoned wood, the glass will tar. This is universal to non-catalytic stoves, not specific to Enerzone.
Trade-offs to know
Same platform as the Osburn 2000. The Solution 2.3 and the Osburn 2000 share the same SBI medium-large stove performance platform — same firebox, same combustion-chamber dimensions, same 20-inch log capacity, same 75,000 BTU/hr maximum output. The Osburn 2000 adds the Osburn brand finish, a required door overlay choice (Black or Brushed Nickel), and the Osburn dealer/parts network positioning. Choose the Solution 2.3 for the Enerzone price point and seven base configurations without the required door overlay step; choose the Osburn 2000 if you want the Osburn brand and the additional overlay finish.
Medium-large firebox, medium-long burn time. A 2.4 ft³ non-cat stove gives you meaningful primary-heat capability across 1,200–1,800 sq ft, with realistic 6–7 hour burn cycles. If you want true 10+ hour overnight burns or 2,500+ sq ft primary heating, step up to a 3.0+ ft³ firebox or to a catalytic stove with a real low-output mode.
The 2,100 sq ft figure is aspirational. The most consistent owner regret across medium-large stoves is buying for the high end of the manufacturer's heating range. If you need to reliably heat more than ~1,800 sq ft as primary winter heat in a cold climate or older home, step up a firebox size — the Solution 3.5 or equivalent gives meaningfully more usable heat for the same operational effort.
Base configuration is a one-time decision. Seven base configurations means the stove can fit many room layouts and aesthetics, but the base is configured at order, not field-swappable. Choose the configuration that matches the room you're putting it in — measure the desired height and confirm the look before ordering.
Blower is not included. Unlike inserts in the catalog, the Solution 2.3 ships without a blower; one must be ordered separately if you want forced-air heat distribution. For a stove sized to do real primary heat across larger spaces, the 130 CFM variable-speed blower is a near-essential add — plan for the line item.
402 lb shipping weight. This is a meaningfully heavy stove. Plan for three-person handling at delivery and installation; the curb-to-room move is not a one-person job.
Wood quality is not negotiable. The most common "the stove doesn't heat" complaint comes from owners running marginally seasoned wood. Secondary combustion works best with dry, properly seasoned fuel, ideally around 15–20% moisture. A pin-type moisture meter is the single best accessory for this stove.
Glass blackens at low burn rates. Universal to non-cat stoves. Daily hot cleanup burns and tolerance for a periodic wipe are part of operating this stove. Owners chasing always-clear glass on long, slow burns should look at catalytic technology.
Refined but not ornate. The Solution 2.3 has clean modern lines, an arched cast-iron door, engraved-groove side panels with nickel U-shaped decorative accents, and a choice of leg styles. It is refined but functional, not heavy decorative cast iron. Buyers wanting furniture-grade cast-iron styling should look at premium-tier alternatives.
Operating reality
First burns. The first few fires cure the high-temperature paint and condition the internal components. Burn two or three small fires first, then build bigger, hotter fires until the paint smell is gone. The smell can be strong; ventilate the room well and avoid prolonged exposure during cure-in.
Lighting. Open the air control fully and build a small, hot kindling fire. The manual's EPA loading sequence uses eight small (2"×2") pieces criss-crossed at the greatest possible angle on the firebox floor, kindling on top in three layers, then five sheets of newspaper tied in a knot on top. Light the paper, leave the door ajar at 90° until the kindling is fully engaged, then close the door. In normal use, the goal is the same: establish draft quickly, get the firebox hot, then close the door once the fire is stable.
Air control. Single-lever, located underneath the ash shelf. Push the handle completely to the left for HIGH (open); push completely to the right for LOW (closed). Full open at light-off; gradually closed only after the load is fully engaged and stable secondary flames are established. The manual specifies closing the primary air control gradually from the time the door closes to fully closed — too fast and the fire smolders.
Reload cadence. 3–4 hours between reloads in active heating use; up to 7 hours for a final overnight pack with the air shut hard. For loading, follow the principle the manual describes for EPA testing: three logs on the coal bed in east-west orientation with one inch of air space from the rear firebrick, two more logs on top angled slightly. Open the air for a minute or two before opening the door, open the door slowly to avoid smoke rollout, load onto the coal bed, close the door, and run the air open until the load is fully engaged before reducing the air gradually. Do not elevate the fire by using a grate.
Ash management. The Solution 2.3 has a built-in ash drawer system (included with each base configuration) — the ash plug in the firebox floor opens to drop ash into the drawer below. Per the manual, empty every 2–3 days during full-time heating. Always dispose of ash in a tightly covered metal container on a non-combustible surface, well away from combustible materials — ash retains hot embers for days.
Glass cleaning. Damp newspaper dipped in cold ash, or a dedicated ceramic-glass cleaner. Daily wipe during low-burn weather; weekly during high-burn. Black streaks at the lower edge mean wet wood; black uniformly across the glass means burns are running too cool. Do not clean the glass when the stove is hot, and do not strike or slam the glass door shut.
Door and glass gaskets. Per the manual, the door gasket needs replacement when the paper-strip test fails: close the door on a strip of paper and try to pull it out; firm resistance means the gasket is sealing, easy pull means it's time to replace. Test all the way around the door, not just at the latch. The latch mechanism is also adjustable — turn the handle one counterclockwise turn (after removing the split pin with pliers) to increase pressure. Replacement is a 30-minute job. Plan on every 3–5 seasons in regular use.
Annual chimney sweep. Per the manual, the chimney should be cleaned and inspected at least once each year. Inspect every two months during the heating season until you know your creosote-formation rate; monthly is safer for new burners. If buildup reaches 1/8 inch, sweep immediately. The baffle and secondary tubes lift out for sweep access.
Wood seasoning. Hardwood needs 12–24 months split, stacked off the ground, top-covered, with sun and wind on the sides. Don't trust supplier "seasoned" claims — use a pin-type moisture meter, split a piece in half, measure the fresh face. Manual target: 15–20% moisture. Wood above 25% will smolder, soot the glass, line the chimney with creosote, and undercut every published efficiency and emissions number on this page.
Blower maintenance (if installed). Keep the blower intake and fins free of dust and follow the blower kit instructions for service. Do not oil the blower unless the blower manual specifically calls for lubrication. Replacement blowers and related service parts are available through Enerzone/SBI dealers and parts channels if needed years out.
What never to burn. Per the manual and EPA fuel rules: no coal, garbage, yard waste, materials containing rubber or plastic, waste petroleum products, paint or paint thinners, asphalt products, painted or pressure-treated wood, railroad ties, manure or animal remains, plywood, particle board, paper products, asbestos materials, construction or demolition debris, salt-water driftwood, or unseasoned wood. This does not prohibit normal fire starters made from paper, cardboard, sawdust, wax, or similar substances when used only to start a fire. Burning prohibited materials destroys the firebox, voids the warranty, and releases toxic compounds into your home and the chimney.
Warranty and service
The Enerzone limited lifetime warranty applies to the original retail purchaser only and is non-transferable. The warranty applies to normal residential use only. Proof of purchase (dated bill of sale), model name, and serial number are required for any warranty claim. Online registration is recommended at enerzone-intl.com but not required if a dated invoice is retained.
Coverage by component
A one-time replacement limit applies to all parts with lifetime coverage. Warranty is void if the unit is used to burn anything other than seasoned cordwood, or if it is not operated according to the owner's manual. Damage caused by misuse, improper installation, lack of maintenance, overfiring, downdrafts, venting problems, or under-estimated heating area is not covered. Improper installation by anyone other than an authorized qualified technician voids the warranty.
Warranty claims are made through your Enerzone dealer and remain subject to SBI/Enerzone inspection, approval, and the current written warranty. Kaminos is the retailer for this stove and supports buyers through purchase; final warranty approval rests with SBI as the manufacturer. SBI's parts network is well-stocked — replacement bricks, baffle, secondary tubes, glass, gaskets, and optional blower are openly available at fair prices through multiple parts vendors.
Enerzone may require photos or returned parts to support a claim; repair work covered by warranty requires prior manufacturer approval.
Coverage details can change by component and warranty revision; the current Enerzone warranty controls.
