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.

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.
TruHybrid™ Catalysts
The catalysts used in our TruHybrid™ system are made from coated stainless steel to ensure a long life, few maintenance concerns, and reliably clean combustion.
