TruHybrid™
Ultra Clean Combustion Systems
All of our wood stoves exceed 2020 EPA standards so you can be sure they burn clean today and for many years to come.
Our TruHybrid™ stoves burn cleanly and efficiently before and after you engage the catalyst. The system combines primary and secondary combustion with tertiary combustion using a catalyst to take care of any unburned smoke particles and gases.
Learn More About TruHybridOur 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.
