Our Materials
Each HearthStone is handcrafted using a combination of precision-made components in cast iron, soapstone, steel, ceramic, and various other materials. Our commitment to quality and attention to detail ensures that your product will serve you faithfully for years to come.
Soapstone
Soapstone is a natural material that absorbs the high heat of a fire, then radiates a gentle heat into the room. Soapstone warms the objects in your home, not just the air, resulting in a comfortable, livable heat.

Cast Iron
Using selected raw and recycled material, our iron parts are produced in our foundry in Spain. Our modern casting facility guarantees durable, reliable, high-quality cast iron parts.

Accessories
Rear Heat Shield
90-68300
The rear heat shield screws to the back of the stove, reducing the required distance between the stove and the wall behind it. The heat shield also provides attachment for the convection blower, sold separately.
Convection Blower
90-57210
The convection blower moves air up and across the stove to circulate more heat into your room. A snap switch turns the blower on automatically. Adjust the rheostat to control the speed of the blower or turn it off.
Outside Air Adapter, 3″
90-53300
Bring air into your stove from outside of your house to ensure proper combustion and keep more heat in your home. Recommended for newer well-sealed homes. 3″ ducting not included.
