Breckwell Stove Comparison Guide

Breckwell Hearth is based at 227 Industrial Park Road in South Pittsburg, Tennessee. The company has produced pellet stoves under the SP1000 platform for over 20 years; the current SP1000E variant of the Big E carries the latest EPA 2020 certification under report number F21-690, tested to ASTM E1509-2022 and CAN/ULC S627:2023. The SW500 wood stove is a newer addition to the lineup, certified under UL 1482-2022 and ULC-S627:2023 with report number F22-781.

Brand position: every Breckwell stove ships with a comprehensive owner's manual, requires installation by a qualified NFI (U.S.) or WETT (Canada) technician for warranty validity, and uses serviceable parts available through authorized Breckwell dealers. Owner registration is available at breckwell.com/product-registration; retain the original receipt for any warranty claim.

The two Breckwell stoves we carry sit at opposite ends of the residential hearth spectrum: the Big E pellet stove is designed for hands-off automatic heating in medium-to-large open-plan spaces with thermostat compatibility, and the SW500 wood stove is designed for off-grid wood-fire heating in small spaces, cabins, and tiny houses where power-independent operation matters.

The Breckwell lineup we carry covers two distinct heating technologies on two purpose-built platforms. They differ across four axes: fuel (PFI Premium grade pellets vs cordwood), combustion control (automated auger-fed feed with electronic control board vs manual damper-controlled secondary burn), electrical dependence (115V required vs no electricity required), and footprint scaling (medium-to-large heating capacity vs compact heating for up to roughly 750 square feet).

The Big E is Breckwell's flagship pellet stove. The SP1000E variant carries EPA 2020 certification at 75 percent efficiency and 1.0 g/hr emissions, tested at heat output ranging from 6,580 to 39,121 BTU per hour. A 140 lb hopper holds roughly three full bags of PFI Premium grade hardwood pellets and feeds the burnpot through an automatic auger system. Five Heat Level Advance settings control the feed rate from 1 (low) through 5 (high); the integrated igniter fires automatically on startup and the green ON/OFF indicator confirms operation. The control board accepts an optional millivolt thermostat for High/Low or On/Off automatic operation, and a Reset Trim function lets the installer adjust the low feed rate for different pellet brands and qualities. The Big E uses 3 inch or 4 inch PL-Vent pipe with horizontal-through-wall, vertical-roof, or existing Class A 6 inch chimney conversion installation options. Outer dimensions 25-3/4 inches high by 32-5/8 inches wide by 23-7/8 inches deep. Best fit: medium-to-large open-plan main living areas where hands-off automatic heating, thermostat control, and a multi-day burn time on a single load matter.

The SW500 is Breckwell's compact non-catalytic wood stove. EPA 2020 certified at 75 percent efficiency and 1.7 g/hr emissions, tested at heat output ranging from 10,652 to 26,028 BTU per hour. The 0.59 cubic foot firebox accepts cordwood up to 11 inches long, with a 9.5 by 10.5 inch pyroceramic glass door and an integrated air wash system to keep the viewing window clean. Combustion is controlled by a single manual slide damper rod located in the center of the stove under the hearth plate: fully closed for low burn, 1/8 inch out for medium, 1/2 inch out for medium-high, and fully out for high burn. Secondary combustion is managed by U-shaped secondary air tubes above the firebox that introduce preheated air to burn off remaining gases. The SW500 vents through a 6 inch black or blued steel chimney connector into either a UL 103 or CAN/ULC-S629 Type HT factory-built chimney or a masonry chimney with a 6 inch fireclay flue. Outer dimensions 13 inches deep by 16.4 inches wide by 33.5 inches tall on the pedestal. Optional B36T blower kit and 50FAK outside air kit available. Best fit: small homes, cabins, tiny houses, additions, garages, and zone heating where off-grid operation independent of electricity matters.

The Big E and the SW500 produce heat from the same source material (wood) but through fundamentally different combustion architectures. Understanding the difference shapes every aspect of daily operation, installation, and long-term ownership.

The Big E burns compressed hardwood pellets fed automatically from a 140 lb hopper into a burnpot by an electric auger. A combustion blower draws air through the burnpot at a controlled rate; a separate convection blower distributes the heated air into the room. An igniter cartridge starts the fire automatically when you press the ON button, and the control board manages feed rate, combustion air, and shutdown. Operation is hands-off: load the hopper, set the heat level (1 through 5), and the stove runs until the hopper is empty (roughly 25 to 100+ hours depending on heat setting). A millivolt thermostat can automate startup and shutdown based on room temperature. The Big E requires a 115V grounded electrical outlet and will shut down during a power outage; the manual instructs to check the heater for smoke spillage and open a window if any smoke spills into the room if power is lost during operation.

The SW500 burns cordwood loaded by hand through the pyroceramic glass door. The manufacturer recommends a top-down fire-building method: largest split pieces on the bottom, smaller pieces stacked crossways above, and kindling and twisted newspaper on top. A single manual slide damper rod located in the center of the stove under the hearth plate controls combustion air: fully closed for low burn rate, 1/8 inch out for medium, 1/2 inch out for medium-high, and fully pulled out for high burn. Secondary combustion is managed by U-shaped stainless steel air tubes above the firebox that introduce preheated air to ignite remaining combustion gases — the source of the EPA 2020 low-emissions rating without a catalyst. The SW500 does not require electricity to operate; an optional B36T variable-speed blower kit (120V 0.55A) circulates air for forced convection but is not required for heat production. The pyroceramic glass and air wash system keep the viewing window clean during normal operation.

• Fuel loading frequency: Big E hopper takes roughly three 40 lb bags of pellets per fill; SW500 firebox takes a few logs per reload, typically every 2 to 8 hours depending on burn rate.
• Fuel cost and availability: Pellets are sold in 40 lb bags at hardware stores and hearth dealers; cordwood is sourced locally (purchased, harvested, or seasoned on the property).
• Storage requirements: Pellets need dry indoor storage to prevent moisture absorption and binder breakdown; cordwood needs 9 to 15 months of seasoning under cover with airflow on all sides until moisture drops below 20 percent.
• Power dependency: Big E fully stops during a power outage; SW500 continues burning regardless of grid status (the optional blower stops, but the fire continues).
• Maintenance routine: Big E requires daily burnpot stirring, monthly interior vacuuming, and annual chimney inspection; SW500 requires daily glass wipe-down, weekly chamber brushing, monthly ash removal, and annual chimney inspection.
• Ambient experience: The Big E shows a smaller flame visible through the smoked glass; the SW500 displays a full visible wood fire behind a large pyroceramic window with the radiant warmth and ambient feel of a traditional wood stove.

• You want hands-off automatic heating. Load 140 lbs of pellets, press the ON button, and the stove can run for days unattended (25 to 100+ hours depending on heat level).
• You want thermostat compatibility. The Big E control board accepts a millivolt thermostat for High/Low or On/Off automatic operation based on room temperature.
• You're heating a medium-to-large open-plan space. The 6,580 to 39,121 BTU/hr tested heat range fits main living rooms, great rooms, and open-plan first floors in average-insulation homes.
• You have a 115V grounded electrical outlet at the install location. Pellet stoves require continuous electrical power for the auger, blowers, and control board.
• You prefer compressed-pellet fuel logistics. Hardware-store-sourced 40 lb bags, indoor dry storage, no chopping or splitting.
• You want short vent flexibility. The Big E uses 3 inch or 4 inch PL-Vent pipe and can vent horizontally through an exterior wall — useful for slab-on-grade homes, mobile homes, or installations where a full Class A chimney isn't practical.
• You're installing in a mobile home. The Big E is mobile home approved and ships ready for the required outside-air, chassis-grounding, and floor-mounting configuration.

• You want off-grid operation. The SW500 produces heat with zero electrical input — critical for off-grid cabins, power-outage backup heat, and remote installations.
• You're heating a smaller space. The 10,652 to 26,028 BTU/hr tested heat range fits cabins, tiny houses, additions, garages, and zone-heating scenarios up to roughly 750 square feet depending on insulation.
• You have access to cordwood. Locally harvested, purchased, or property-seasoned firewood is cheaper per BTU than pellets in most regions and bypasses the pellet supply chain entirely.
• You want a visible wood fire. The 9.5 by 10.5 inch pyroceramic glass door with air wash system delivers the visual and ambient experience of a traditional wood stove.
• You're installing in a mobile home or tight space. The SW500 is mobile home approved, the 13 inch depth and 16.4 inch width fit tight floor plans, and the pedestal base keeps the footprint compact.
• You have or can build a UL 103 / CAN/ULC-S629 Type HT 6 inch chimney. Or a masonry chimney with a 6 inch fireclay flue meeting NFPA 211 — the SW500 connects to a standard 6 inch chimney system, no specialty pellet vent required.
• You want low ongoing fuel-handling complexity. No pellet brand selection, no feed-rate trim adjustment, no auger maintenance — just load wood, set damper, and burn.

The Big E must be placed on a continuous non-combustible floor protector (ceramic tile, cement board, brick, 3/8 inch millboard or equivalent) with a minimum R1 insulative rating. Ceramic tile installations require a continuous sheet beneath to prevent embers from falling through to combustible flooring through any joint separation.

Vent the Big E with listed Type PL-Vent in 3 inch or 4 inch diameter. The stove was tested with Simpson Duravent brand pipe. Class A chimney is not required. All vent connector joints must be sealed with 500°F RTV silicone; horizontal connector joints must be sealed with UL-181-AP foil tape; vertical connector joints must be secured with a minimum of 3 screws. Mobile home installations require an outside combustion air kit: a 2 inch inside diameter metallic pipe attached to the inlet at the stove's rear with a rodent guard wind hood at the terminus, 8 gauge copper grounding to the steel chassis, and 2-1/4 inch lag bolts through the floor mounting holes. The Big E must not be installed in an alcove.

The SW500 must be placed on a non-combustible floor protector (UL 1618 listed or equal) with a minimum R-Value of 2.8 if the floor is constructed of combustible material. The floor protector must extend 18 inches in front of the door, 8 inches on each side, and 2 inches at the rear. Minimum floor-to-ceiling height is 7 feet (2.13 m); no combustible material is permitted within 18 inches of the front of the stove.

• Venting: 6 inch black or blued steel chimney connector (2,100°F / 650°C rated). Connect to a UL 103 or CAN/ULC-S629 Type HT (2,100°F) factory-built chimney or a masonry chimney with a 6 inch fireclay flue meeting NFPA 211.
• Minimum chimney height: 12 feet (3.7 m) total height.
• Total connector run: Should not exceed 8 to 10 feet to ensure proper draft, except in cathedral-ceiling vertical installations.
• Mobile home installation: Outside air kit (50FAK or 4FAK) is mandatory. Factory-built chimney must comply with UL 103 (650°C Type HT). Spark arrester required. Stove must be electrically grounded to the steel chassis with 8 gauge copper wire and bolted to the floor through the mounting holes in the pedestal base. Do not install in a sleeping room.
• Important restrictions: Do not install in an alcove. Do not install in a factory-built fireplace.

Four questions narrow the choice between the Big E and the SW500: how much space you need to heat, what fuel you have access to, whether you need power-independent operation, and how hands-on you want to be day-to-day.

• Up to roughly 750 square feet (cabin, tiny house, addition, garage, zone heating): The SW500 wood stove is sized for compact spaces. Its 10,652 to 26,028 BTU/hr range and 0.59 cu ft firebox match small-footprint heating needs and the pedestal base fits in 13 inches of depth.
• Medium-to-large open-plan main living area: The Big E pellet stove 6,580 to 39,121 BTU/hr range covers a much broader heating envelope. The 140 lb hopper supports multi-day unattended operation.

• Pellets readily available at hardware stores or hearth dealers, dry indoor storage available: The Big E uses PFI Premium grade hardwood pellets in 40 lb bags. Three bags fill the hopper.
• Cordwood available locally (purchased, harvested, or property-seasoned): The SW500 burns standard cordwood up to 11 inches long. Wood must be seasoned 9 to 15 months under cover with airflow until moisture content drops below 20 percent.

• Power-outage backup heat or off-grid installation: The SW500 runs without electricity. Optional B36T blower needs power for forced air circulation, but the stove produces heat regardless of grid status.
• Grid-tied home with reliable electrical service: The Big E needs continuous 115V power for the auger, blowers, and igniter. It will not operate during a power outage. A surge protector is required.

• Load and walk away, possibly with thermostat automation: The Big E runs hands-off once the hopper is loaded. A millivolt thermostat fully automates start, run, and shutdown based on room temperature.
• Active wood-fire management with visible flame: The SW500 requires manual fire building, periodic reloading, and damper adjustment. In exchange you get a visible wood fire behind a 9.5 by 10.5 inch pyroceramic glass window.

• Cabin or tiny house with no grid power: SW500 wood stove with a 6 inch UL 103 Type HT factory-built chimney, no blower required.
• Mobile home main heat with thermostat control: Big E pellet stove with the outside air kit, 8 gauge chassis grounding, floor-mounting lag bolts, and an optional millivolt thermostat for automated room-temperature control.
• Garage or workshop zone heating: SW500 with the optional B36T blower for forced air circulation across the space.
• Main living room of a slab-on-grade home with no existing chimney: Big E vented horizontally through the exterior wall using 3 inch PL-Vent — avoids the cost of building a full Class A chimney.
• Power-outage backup heat for a grid-tied home: SW500 as the secondary heater. Continues operating when the furnace or pellet stove shuts down with the power.
