Product Features

TruHybrid™ Combustion Technology

The TruHybrid™ system burns the fuel, then the gases the wood releases, then routes the remaining exhaust through a catalyst for tertiary combustion. A bypass handle directs combustion products around the catalyst during startup and reloading, and through the catalyst once the catalyst probe shows the stove is in its active range. The Heritage uses two Applied Ceramics ACI-6M2 catalytic combustors, which require periodic inspection and eventual replacement.

Soapstone and Cast Iron Construction

The Heritage is built with full cast iron construction and a 1¼" soapstone lining. Soapstone absorbs the heat of the fire and releases it gradually, warming objects in the room rather than only the air. HearthStone notes that soapstone requires gradual break-in fires so the natural moisture in the freshly quarried stone is driven out slowly, and that stone color may change and surface fractures may appear with use without affecting stove function.

Side-Loading Convenience

Wood is loaded through the side door as well as the front, and the Heritage is ordered as either a left-loading or right-loading stove. The loading side affects hearth pad layout, so it should be selected against the intended installation. The optional Side Door Lock Kit reduces the minimum required hearth pad width.

Cast Iron and Enamel Finishes

The Heritage is offered in Matte Black and in Brown, Black, and Seafoam porcelain enamel. Enamel finishes are covered against peeling or fading for one year under the HearthStone limited warranty, and replacement stones and enameled parts are drawn from current stock and may vary from originals in color, grain, or pattern.

Fire Viewing and Everyday Operation

A large glass window lets the fire be seen from a variety of locations in the room. A single primary air lever below the ash lip regulates the burn rate, the bypass handle controls catalyst engagement, and a catalyst probe shows when the stove is in its active temperature range, typically 800°F to 1300°F. An optional ash pan with a shaker grate allows ash removal without shoveling through the front door.

Heating Performance

HearthStone publishes a heating area of up to a maximum of 2,000 square feet and output of up to 60,000 BTU. Under EPA test conditions with Douglas fir test wood, the Heritage 8024 delivered heat at rates ranging from 12,889 to 29,191 BTU/hr. HearthStone states in the current owner's manual that the Heritage 8024 should not be considered the primary heat source for a home, and that factors unique to a given house can reduce the square footage the stove will heat.

Available Finishes and Loading Configurations

The Heritage 8024 is built in both left-loading and right-loading versions, and every finish is available in either loading configuration. Pricing varies by finish rather than by loading side.

Pricing notice: Prices shown are current manufacturer-suggested retail prices for the stove in the selected finish and loading configuration. Chimney components, hearth protection, accessories, delivery, installation, and applicable taxes are additional.

Clearances and Hearth Requirements

The values below are from the current Heritage 8024 owner's and installation manual. Reduced clearances require the HearthStone rear heat shield, kit 90-68210, and listed close-clearance connector pipe. Double-wall connector figures shown by HearthStone are specific to Simpson Dura-Vent DVL and may vary with other brands.

Corner clearances account for clearance of combustibles to the body of the stove only. Minimum hearth pad dimensions must still be maintained and may result in larger distances to the actual combustible surfaces. Canadian installations require additional clearance for several of these measurements; refer to the current manual for the Canadian figures.

Alcove installation, unprotected surfaces

Hearth and floor protection

Combustible flooring must be protected with a covering of noncombustible material. The Heritage 8024 does not require an insulated hearth pad and there is no R-value requirement; the requirement is ember protection. The dimensions below are measured from the body of the stove, not the legs, and extend beyond the stove as shown.

HearthStone notes that luxury vinyl plank and luxury vinyl tile flooring warrants extra consideration, as some products begin to warp at 110° Fahrenheit, and that additional shielding may be necessary depending on the flooring used.

Installation notice: Clearances and hearth requirements vary by connector type, shielding, loading-door orientation, and installation configuration. Refer to the current Heritage installation manual and applicable local requirements before installation.

Warranty

HearthStone warrants the appliance to the original retail purchaser only, when purchased by that purchaser and installed by an authorized HearthStone dealer or their designated representative, against defects in material or workmanship. Coverage begins on the date of the original invoice and is not transferable to subsequent owners.

Warranty periods differ by component. HearthStone defines the term "Limited Lifetime" as 10 years from the beginning of warranty coverage, and applies it to the stone, to cast iron not listed elsewhere, and to the clean-burning air supply system. Door handles and latches and steel components and the firebox carry a 5-year period. Appliance electrical components carry a 2-year period. Enamel finish against peeling or fading, glass, the ash grate, accessories, and all components not listed elsewhere carry a 1-year period. The catalytic combustors are covered directly by the combustor manufacturer, Applied Ceramics, under a separate limited warranty that provides free replacement within two years of purchase and prorated replacement pricing thereafter.

HearthStone pays for warranty labor performed by an authorized dealer during the first year after the purchase date only when the appliance was installed by an authorized dealer or their designated representative; otherwise, and thereafter, labor is the purchaser's responsibility. Exclusions include over-firing, improper installation or operation, service by anyone other than an authorized dealer, use of unapproved fuels or components, water and corrosion damage, and normal wear parts such as paint, gaskets, baffles, refractory materials, ash grates, and glass. Surface and hairline cracks and scratches in the stone that do not affect operation or safety are excluded, and HearthStone's obligation does not extend to the appliance's ability to heat a desired space. Warranty registration is not required as a condition of coverage. Refer to the complete warranty in the current Heritage 8024 owner's manual for the full terms, conditions, and limitations.
