Enerzone Pyra Wood Cookstove

Right buyer

Owners of cabins, cottages, off-grid homes, and open-plan kitchens who will actually cook on a wood appliance during heating season — not just in a power outage — and who want the rare modern cookstove that combines a real bake oven, a real cooktop, and EPA 2020 cordwood compliance with the option to install it in a mobile home or a tight modern kitchen.

Suited to homesteaders, cabin owners, and lifestyle bakers who want one appliance to heat the room, bake bread, simmer soup, and roast a chicken, in a kitchen, dining room, or great room of roughly 1,000–1,800 sq ft with reasonable insulation and access to seasoned hardwood at 15–20% moisture content.

Mobile-home and dual-purpose-room friendly with the optional fresh-air intake kit, double-wall connector pipe, and structural attachment per the manual. The included glass-fronted oven door with integrated thermometer and SBI lifetime warranty give it a service profile most cookstoves in the category cannot match.

Wrong buyer

Not for buyers who want a primary heater that occasionally cooks. A cookstove of comparable BTU output costs roughly $1,500–$2,500 more than a heating stove of the same firebox size, requires a larger hearth pad, locks the install to the kitchen zone, and adds a real cooking learning curve. Buyers who would only cook on the appliance a few times a year are almost always better served by a heating stove with a flat cast-iron top.

Not for buyers who need an integrated hot-water reservoir or coil. The Pyra has neither. Off-grid buyers whose cookstove is also their primary domestic hot-water source should look at traditional homestead cookstoves with factory water-heating options.

Not for buyers expecting set-and-forget operation. A wood cookstove is, in the manual's own words, "an art that requires several attempts." Plan for a full heating season of regular use before bread comes out the way it should. The oven dial is approximate; an internal probe thermometer is the right tool for serious baking.

Not for buyers who want enameled-tile Italian aesthetics or a true British range-cooker. The Pyra is modern North American — cast-iron columns with engraved fluting, painted steel and cast iron, glass on both doors. Buyers who want porcelain-enamel color tiles or a multi-pan range hotplate are buying a different kind of object at a different price point.

Not for whole-house primary heat in cold climates above 2,100 sq ft. The Pyra is sized for one zone or one open-plan floor; in colder regions and larger homes it is supplemental.

Not for buyers in HOA or air-quality-restricted jurisdictions without first confirming local code permits a new wood-burning install. Not approved for installation in a sleeping room or in an alcove.

The Pyra is designed for indoor installation in a permitted residential space — a kitchen, dining room, mudroom, sunroom, or great room with adjacent kitchen function. It is approved for mobile-home installation only when the manual's mobile-home requirements are met, including outdoor combustion air, insulated intake pipe, double-wall venting, attachment to the structure, and no sleeping-room installation. It is not approved for alcove installation, factory-built (prefab) fireplace installation, or outdoor or unconditioned-space installation.

Clearances to combustibles — USA

Clearances to combustibles — Canada

The 15-inch side-wall clearance applies in both single-wall and double-wall pipe configurations — switching to double-wall does not reduce side-wall distance on this cookstove. The certification label on the back of the cookstove is the binding clearance for any installation and always overrides clearance figures published in any other media. Reduced clearances are available with approved heat shields per the manual. Most installers default to double-wall connector pipe to gain the closer back-wall clearance. For mobile-home installations, use the manual's mobile-home clearance table — double-wall pipe is required and the platform-to-ceiling clearance may differ. Confirm the binding clearance figures with your installer before purchase.

Floor protection

A continuous non-combustible ember-protection surface is required on combustible flooring. Steel of at least 0.015" thickness, cement board, brick, sealed-grout ceramic tiles over a continuous non-combustible sheet, or another approved listed material may be used. Tile alone is not sufficient — the manual requires a continuous non-combustible sheet beneath any tile installation. Most installers extend the pad farther forward (24–36 inches) for cooking ergonomics, since the working zone in front of the oven is part of the cooking workspace. No R-value is required by the manufacturer.

Leveling

Unlike a heating stove, a cookstove must be precisely level for the oven to bake evenly. Adjust per the manual until the cooktop reads level on a bubble level in both directions before final connection. This is not optional — oven hot-spot behavior depends on it.

Chimney and venting

The Pyra 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 cookstove 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. The cookstove must be attached to the home structure and may not be installed in a sleeping room.

Connector pipe

Single-wall or double-wall is permitted in conventional homes; double-wall is required for mobile-home installations. Maximum two 90-degree elbows; double-wall is preferred for closer wall clearances and more stable draft.

Outside air and range hood interaction

The SBI AC01211 fresh-air intake kit (sold separately) is mandatory for mobile-home installation, and is the cleanest solution for tight new-construction kitchens or kitchens with a powerful range hood — range-hood depressurization is a real risk in cookstove installs and can pull smoke out of the firebox or back-draft the chimney. Install it if the kitchen has a high-CFM hood, an HRV, a tight building envelope, or any combination of those. A smoke detector and carbon monoxide detector are required in the room where the cookstove is installed.

The 75,000 BTU/hr figure on the spec sheet is a maximum-output rating based on dry cordwood at high loading density and short reload intervals. It is real, but it is a peak rating, not the average output across a full burn cycle of normal cooking-mode operation. The figure that matters for daily life is the sustained output across a burn cycle, which depends heavily on wood density, moisture, and air setting. A working baking burn delivers roughly 14,000–47,000 BTU/hr into the kitchen per the CSA B415.1-10 stack-loss method.

A realistic operating day with active cooking, cold-climate use: morning fire from a cold start takes about 45 minutes to bring the oven to operating temperature — the iron mass has to soak through, and the dial reading ahead of that is misleading. Once at temperature, a 3/4-full firebox of small dry hardwood splits with the air control closed to about 1/3 open will hold a baking temperature for 60–90 minutes, with one small reload at the 30-minute mark for longer bakes. For artisan sourdough or slow roasts, plan to reload one small split every 20–25 minutes. With seasoned oak, maple, beech, or hickory, expect steady cooking output for 4–6 hours of active session use.

The cooktop temperature gradient is the heart of cookstove cooking. Hottest directly above the firebox, cooler toward the far end, warmest center over the oven section. A pan slid left toward the firebox sears or boils; slid right it simmers; parked over the oven section it holds warm. Cookstove operators learn to cook with multiple pans simultaneously across the gradient.

The oven has a temperature gradient between hottest and coolest points — this is normal for any wood cookstove and is acknowledged in the manual. Owners adapt by rotating loaves during the bake and using a pizza stone or cast-iron sheet on the lower rack to even out bottom heat. Oven dial accuracy across the cookstove category is approximate at best; the dial is a trend indicator, not a precision instrument. An internal probe thermometer is the right tool for first-year baking.

The optional 130 CFM variable-speed blower meaningfully improves heat distribution from the cookstove into adjacent rooms. The variable-speed control lets you dial CFM up or down, and the thermodisc senses cookstove temperature and runs the blower automatically when the cookstove is hot enough — typically about an hour of warm-up time before the blower activates. At lower settings the blower is unobtrusive; at higher settings it is audible. Unlike SBI's heating stoves where the blower is included, on the Pyra it is an option that has to be specified at order.

Air-wash glass on the firebox door stays largely clear during proper hot burns. At low burn rates with marginally seasoned wood — or during slow cooking-mode operation — the bottom edge of the firebox glass will tar. This is universal to non-catalytic tube cookstoves, not specific to Enerzone, and is the strongest signal that your wood is too wet or your burn is too cool. The oven glass stays cleaner because it is not in the soot path.

A cookstove costs more than a heater of similar BTU output. A comparable-firebox heating stove (Enerzone Solution 2.3, Drolet Escape 1800) at the same heating range costs roughly $1,500–$2,500 less than the Pyra and gives you a flat cast-iron top that handles a kettle and the occasional pot just fine. The cookstove premium pays for the integrated oven, the glass oven door, the cooktop area, the cookstove styling, and the engineering that wraps flue gases around the oven before they exit. If you would only cook on the appliance two or three times a year, a heating stove with a flat top is the right tool.

Install location is locked to the kitchen zone. A heating stove can go in a basement, a back room, a corner of a great room. A cookstove only earns its premium where the cooking actually happens. That means kitchen, dining room, mudroom, or great room with adjacent kitchen function — never a basement, never a bedroom, and the install footprint has to share a room with the range hood, refrigerator, and cabinetry. The Pyra needs hearth space extended forward for cooking ergonomics, not just code-minimum ember protection.

One-season learning curve. The manual's own framing is honest: cooking with a wood cookstove is "an art that requires several attempts." Plan for ruined first loaves, overcooked roasts, and a discovery period figuring out which split sizes give you a steady oven, what your stove's hot zones are, and how to time reloads. Keep a logbook of stove temp, oven temp, wood type, and outcome for the first season — the experienced cookstove owners on every forum recommend this.

Cooktop surface care. Use cast-iron or stainless cookware with smooth bottoms; lift rather than slide pots when possible to preserve the finish. Owners who want to cook directly on a contact surface can upgrade to the optional steatite (soapstone) cooking plates (SBI AC01212) from the manufacturer's options list — sold separately.

Wood loading is more particular than for a heating stove. Cookstove ovens want a steady moderate fire of small dry splits, not a packed firebox roaring out the secondaries. Most owners maintain two wood piles — a "cookstove pile" of small straight 3–4 inch hardwood splits, and a regular pile for everything else. Wet wood that a heating stove will tolerate at 22–25% moisture will ruin a baking session entirely.

Summer use is impractical. A working Pyra burn delivers 14,000–47,000 BTU/hr into the kitchen. In October that is welcome. In July it is a sauna. Almost no one runs a cookstove year-round; plan for a summer cooking alternative (propane range, induction cooktop, outdoor grill, outdoor wood-fired oven) and a way to access cookware and pantry that doesn't require lighting the cookstove.

No integrated water heating. The Pyra has no factory hot-water reservoir or coil option. Off-grid buyers who want their wood appliance to also be the domestic hot-water source should look at traditional homestead cookstove brands that offer integrated water-tank designs.

Blower is not included. Unlike SBI's larger heating stoves (Solution 3.5, Osburn 3500) where the 130 CFM blower comes in the box, on the Pyra it is an optional add-on (SBI AC01000). For a cookstove sized to do real primary heat across an open-plan home, plan for the blower line item.

Door alignment and gasket maintenance. Cookstove doors are larger and span a wider thermal gradient than heating-stove doors, which makes them more prone to warping over time. Expect to make small adjustments after the first heating season as gaskets compress, and plan for gasket replacement every 3–5 seasons of regular use.

First burns. The first three to six fires release paint VOCs as the high-temperature stove paint cures. The smell can be strong during paint cure-in. Ventilate the room well, avoid prolonged exposure, and expect the odor to disappear after the first several hot burns. Do not put food in the oven during cure-in.

Lighting. The manual recommends a structured top-down method specifically tuned to the Pyra firebox: split the start-up fuel into pieces criss-crossed in rows on the brick (smallest, biggest, medium), then pieces of small kindling criss-crossed on top in rows, then newspaper sheets over the kindling. Light the paper, leave the door open at 90° for a brief warm-up period, then close. This produces a fast, clean ignition with minimal smoke.

Air control. The single lever under the firebox door controls primary and secondary air simultaneously. Full open at light-off, gradually closed only after the load is fully engaged and stable secondary flames are established. The manual recommends reducing the air partially during steady-state cooking — you rarely fully close the air on a cookstove because the oven needs sustained combustion to hold temperature. Do not alter the air-control limit screws to chase higher firing rates — against federal regulations and voids warranty.

Cooking technique. Build a hot fire on a 3/4-full firebox, wait until secondaries are running and the oven reaches operating temperature, then close the air control partially. The oven coasts to baking temperature and holds for 60–90 minutes. Reload one small split at the 30-minute mark for longer bakes. Cooktop temperature is regulated by pan position, not by the air control: pan over the firebox sears, pan over the oven section simmers, pan at the far edge holds warm. Wood-fired ovens often bake faster than the dial reading suggests because of penetrating radiant heat from the cast-iron and steel mass — owners often adjust recipe temperatures downward and watch the bake closely the first few times.

Reload cadence. 4–6 hours between reloads in active heating use; 6–8 hours for a final overnight pack with the air shut hard. For active baking sessions, plan for one small reload every 20–30 minutes to hold oven temperature. Open the air, wait 30 seconds, open the door slowly to avoid spilling smoke into the room. Turn the blower OFF before opening the firebox door fully — per the manual, otherwise the blower will blow ash out of the combustion chamber.

Ash management. The pull-out ash drawer makes daily-to-weekly removal cleaner than shoveling. The manual recommends emptying every 2–3 days during full-time heating. Always operate the cookstove with the ash drawer in place. 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 (SBI AC07825). Daily wipe during low-burn cooking weather; weekly during high-burn. Do not use abrasive products. Do not clean the glass when the cookstove is hot. Black streaks at the lower edge mean wet wood; black uniformly across the glass means burns are running too cool. Oven glass stays cleaner than firebox glass and usually only needs an occasional wipe.

Cooktop and oven cleaning. Wipe the cast-iron cooktop with a soft damp cloth when cool. For touch-up, the manufacturer offers AC05959 metallic black stove paint. Clean the stainless-steel oven interior with a soft cloth and mild soap; do not use abrasives. Stainless oven discoloration to a golden or bronze tint is normal heat coloration and not a defect.

Door alignment and gasket replacement. The door seal can be verified with a paper-strip test: 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. Gasket replacement is a 30–45 minute job; materials are available through the manufacturer's parts network.

Annual chimney sweep. Per the manual, the chimney should be cleaned and inspected at least once each year, with monthly checks during the heating season until you know your creosote-formation rate. If buildup reaches 1/8 inch, sweep immediately. Heavy cookstove use with marginally seasoned wood will produce more creosote than a heating stove burning hot — cookstove gas paths route around the oven mass before exiting and run cooler than a straight-up heating-stove flue.

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 — buy 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 — and will make baking essentially impossible.

Cooking-specific wood selection. Smaller splits (3–4 inches), well-seasoned hardwood (oak, maple, beech, hickory, ash). Avoid soft woods (pine, fir, poplar) for cooking — they burn too fast and spike oven temperature. Avoid resinous woods entirely — they can foul the oven gas path. Maintain a separate small-split cookstove pile distinct from your bulk overnight-burn pile.

What never to burn. Per the manual and EPA fuel rules: no charcoal, garbage, yard waste, materials containing rubber or plastic, waste petroleum products, paint or paint thinners, asphalt products, painted or pressure-treated wood, railroad ties, pallets, manure or animal remains, plywood, particle board, paper products, cardboard, 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 and oven path, voids the warranty, releases toxic compounds into your home and the chimney, and contaminates anything you cook in the oven afterwards.

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 cookstove 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, blower, and accessory kits are openly available at fair prices through the SBI dealer and parts vendor network.

Enerzone may require photos or returned parts to support a claim; repair work covered by warranty requires prior manufacturer approval.
