Ask anyone who has lived with a soapstone stove and they’ll tell you the same thing: the heat is different. Not the blast-furnace-then-cold cycle of a steel stove, but a steady, gentle warmth that keeps coming long after the fire has burned down. That experience is what HearthStone® has been building in Morrisville, Vermont since 1978—and it’s why HearthStone makes three bold claims about its stoves: the most comfortable, the most efficient, and the best looking.

This is a dealer’s guide to the brand—who HearthStone is, how a Vermont stove company became a leader in clean-burning technology, what soapstone and TruHybrid™ combustion actually do, what sets HearthStone apart from the other wood brands we carry, and a model-by-model overview of the four stove families so you can find the right fit. We’ll be honest about who HearthStone is for, because that’s how we help customers choose in our showrooms.

From Leisure Time Inc., an authorized HearthStone dealer with hearth showrooms in Boise, Idaho Falls, and Twin Falls. We carry more than a dozen fireplace brands, so when we recommend HearthStone, it’s because it’s the right stove for the home.

The Short Answer: Why Choose HearthStone

If you want the quick version before the details, here’s why HearthStone earns a spot in our showrooms:

• The most comfortable heat you can get from wood. Soapstone absorbs the sharp heat of the fire, stores it, and radiates it back gently for hours—so the room stays even instead of swinging hot and cold.
• Among the cleanest, most efficient stoves made. HearthStone’s TruHybrid™ combustion reaches up to 81% overall efficiency, and every HearthStone wood stove meets the high-efficiency standard—more models than any other manufacturer.
• Handcrafted in Vermont, and signed. Every HearthStone soapstone stove is signed by the craftsman who built it.
• A style for every home. Four families—classic soapstone, enameled cast-iron Traditions, black cast-iron Green Mountain, and the German-built HASE modern line—in multiple sizes each.
• Heat with no grid dependence. Wood stoves run with no electricity, and a soapstone stove keeps radiating warmth for hours even after the fire fades—ideal for an Idaho power outage.

Now, here’s the story behind all that.

A Brief History: A Vermont Stove Company Since 1978

HearthStone has been building wood stoves in Morrisville, Vermont—in the heart of a state that knows about long winters—since 1978. From the beginning, the company’s signature was a construction most of the industry didn’t use: solid soapstone walls framed in cast iron, combining a natural stone’s ability to store heat with iron’s strength and style. HearthStone has been building soapstone stoves that way, by hand, for nearly five decades.

The company’s other defining thread is clean combustion. When the EPA set its first emission standards for wood heaters in 1988, then tightened them in 2015 and again in 2020, HearthStone treated each update as an opportunity rather than an obstacle—inventing new technology to meet it. The result was TruHybrid™, a combustion system that made HearthStone stoves some of the cleanest and most efficient in existence, and the reason every current HearthStone wood stove meets the EPA 2020 standard.

Along the way HearthStone partnered with HASE, a German manufacturer of precision modern stoves, to add a contemporary family to its lineup, and expanded into HearthStone Outdoor (wood-fired pizza ovens) and HearthStone Cookware. But the core hasn’t changed: Vermont craftsmen handcrafting stoves to the highest standards, and signing their names to the soapstone ones. As HearthStone puts it, the brand is ‘an assurance’ that your stove is built in that tradition and will serve you for years.

What Makes HearthStone Different

Plenty of brands make a good wood stove. A few things set HearthStone apart when you see them side by side with the other wood brands we carry:

• Soapstone construction: Solid 1¼-inch soapstone walls (or a 1¼-inch soapstone lining inside the cast-iron families) that store the fire’s heat and release it slowly. It’s the single biggest reason HearthStone heat feels different.
• TruHybrid™ combustion: A hybrid system that burns cleanly and efficiently both before and after you engage the catalyst—smokeless startups, then long, efficient burns that make the most of your woodpile.
• Real efficiency numbers: Up to 81% overall efficiency (HHV) on TruHybrid products, and every HearthStone wood stove meets the 75% HHV high-efficiency threshold.
• Long burn times: Load the stove at night, close the air control, and wake up to a warm house and live coals—HearthStone stoves are built to burn low and slow.
• Simple to run: A single-lever air control and a catalyst control handle. Open it to start clean; close it to burn long. No fiddling.
• European cast iron and porcelain enamel: The Soapstone and Traditions families are framed in European iron with a choice of enamel finishes—furniture-grade pieces, not utility appliances.
• Four families, every style: From the quintessential soapstone Heritage to the German-built, ceramic-clad HASE Bari, there’s a HearthStone for a farmhouse, a cabin, or a modern loft.
• Dealer-only: HearthStone sells through authorized dealers, so every stove is specified, installed, and supported by a hearth professional.

The Technology Behind the Heat

Soapstone: The Most Comfortable

Soapstone is a natural stone with an unusual property: it absorbs heat slowly and releases it slowly. In a HearthStone, the stone walls soak up the sharp, intense heat of the fire, store that energy, and radiate it back into the room as a gentle, even warmth. The practical effect is a home that stays at a comfortable temperature all day—and keeps radiating heat for hours after the fire has died down. A steel stove gets hot fast and cools fast; a soapstone stove smooths the whole curve.

TruHybrid™: The Most Efficient

TruHybrid is HearthStone’s combustion system, and ‘hybrid’ is the key word: it combines secondary combustion (burning the gases and smoke that a plain fire would send up the chimney) with a catalyst that lets the stove keep burning cleanly at the low, slow settings you use overnight. The result is clean, efficient combustion whether the catalyst is engaged or not, with up to 81% overall efficiency—more heat from less wood, and far less smoke. It’s why HearthStone led the industry into the EPA 2020 standard rather than scrambling to meet it.

Cast Iron + Soapstone Lining

HearthStone’s Traditions and Green Mountain families are cast-iron stoves—but lined with the same 1¼-inch soapstone. You get the classic look and durability of iron with a noticeably more comfortable, longer-lasting heat than a traditional all-iron stove. It’s a best-of-both approach that no other major brand builds this way.

The HearthStone Lineup: A Model Overview

HearthStone organizes its wood stoves into four families by construction and style. Every stove below is EPA 2020 certified with TruHybrid™ combustion.

The Soapstone Family (Solid Soapstone + European Cast Iron)

The Traditions Family (Enameled European Cast Iron, Soapstone-Lined)

The Green Mountain Family (Black Cast Iron, Soapstone-Lined)

The Modern Stove Family (HASE, Made in Germany)

Beyond Stoves

Which HearthStone Is Right for You?

With four families and a range of sizes in each, the right model comes down to your space, your style, and how you’ll use it. Here’s how we narrow it in the showroom:

1. Want the full soapstone experience? The Soapstone Family—Heritage for the classic choice, Mansfield for a large home, Castleton for long burns, Lincoln for a small room.
2. Want color and a furniture-grade finish? The Traditions Family’s porcelain enamel—Manchester for the most features, Shelburne for up to 2,000 sq ft, Craftsbury for a smaller home.
3. Want clean black cast iron at a strong value? The Green Mountain Family—sized 20 through 80 to match almost any room.
4. Want a modern stove for a contemporary home? The HASE Bari or Bari Plus.
5. Heating a cabin, tiny home, or single room? The Green Mountain 20, the Lincoln, or the Craftsbury.
6. Heating a large open home or counting on overnight burns? The Mansfield, Manchester, or Green Mountain 80.
7. Building new and want a built-in? A HearthStone zero-clearance wood fireplace like the WFP 100.
8. Upgrading an open masonry fireplace? A Green Mountain wood insert.
9. Want wood heat and a wood-fired kitchen? The Deva cook stove.

HearthStone vs. Other Wood Stove Brands: An Honest Comparison

We carry HearthStone alongside Stûv, Vermont Castings, and Idaho’s own Kuma, and customers often ask how they compare. The honest answer: each has a clear strength.

• Choose HearthStone if you want the steadiest, most comfortable heat from wood (soapstone), the longest, cleanest burns (TruHybrid), overnight heat that lasts, and a handcrafted stove in a classic or enameled style—or the HASE Bari for a modern room.
• Choose Stûv if architectural, minimalist design is the priority, or you want an open-fire option and features like a rotating stove or double-sided fireplace.
• Choose Vermont Castings for its classic cast-iron styling and heritage designs.
• Choose Kuma for an Idaho-made stove with a hard-working, no-nonsense design.

All of them heat without electricity, all are available EPA certified, and all come with full dealer support from us. The best way to decide is to see them side by side—and with HearthStone, to feel the difference soapstone makes.

Frequently Asked Questions

Where are HearthStone stoves made?

HearthStone stoves are handcrafted in Morrisville, Vermont, where the company has been building soapstone wood stoves since 1978. Every HearthStone soapstone stove is signed by the craftsman who built it. The brand’s Modern Stove Family is built by its German partner HASE, which precision-manufactures its steel, ceramic, and vermiculite components in-house.

What is soapstone, and why does HearthStone use it?

Soapstone is a natural stone that absorbs heat slowly and releases it slowly. HearthStone builds its stoves with solid 1¼-inch soapstone walls (or a soapstone lining inside its cast-iron families) so the stone soaks up the fire’s sharp heat, stores it, and radiates it back as gentle, even warmth. The result is a home that stays comfortable all day and keeps getting heat for hours after the fire dies down.

What is TruHybrid combustion?

TruHybrid is HearthStone’s combustion system, combining secondary combustion with a catalyst so the stove burns cleanly and efficiently both before and after the catalyst is engaged. Open the catalyst control for a smokeless startup; close it for long, efficient burns. TruHybrid products reach up to 81% overall efficiency (HHV), and every HearthStone wood stove is EPA 2020 certified.

How long does a soapstone stove stay warm?

Hours. Because soapstone stores heat, a HearthStone continues radiating warmth long after the fire has burned down—which is why a stove loaded at bedtime can keep a home comfortable through the night and still be warm in the morning. Combined with TruHybrid’s long burn times, it means fewer reloads and a steadier temperature than a steel stove.

Do HearthStone stoves qualify for a tax credit?

Every HearthStone wood stove meets the 75% HHV efficiency standard that qualified for the federal 25C biomass tax credit—but that federal credit expired on December 31, 2025, so it doesn’t apply to new purchases. Idaho offers its own residential alternative energy tax deduction for qualifying EPA-certified wood stoves. Rules and eligibility apply, so confirm with a tax professional before counting on any savings.

Is HearthStone a good choice for a cabin or mountain home in Idaho?

It’s one of the best. A HearthStone runs with no electricity, soapstone keeps radiating heat for hours during an outage, and TruHybrid’s long burns mean fewer trips to the woodpile on a cold night. For a smaller cabin, the Green Mountain 20, Lincoln, or Craftsbury fit the space; for a larger mountain home, the Mansfield, Manchester, or Green Mountain 80 carry the load. We’ll help you size it.

HearthStone is the brand we recommend to anyone who wants wood heat that’s comfortable to live with—steady, long-lasting, clean, and built by hand in a place that understands winter. Whether that’s a Heritage anchoring a farmhouse living room, a Green Mountain 60 heating a cabin through the night, or a HASE Bari in a modern great room, the best next step is to see one. Bring your square footage and a photo of the space, and we’ll help you choose the family and the size, spec the installation, and give you a straight answer on pricing before you decide.

Soapstone comfort, TruHybrid efficiency, and a dealer who installs it right—that’s HearthStone from Leisure Time Inc.
