EPA 2020

A new low emission standard for solid fuel heaters takes effect in 2020.

On May 15th of 2020, new EPA regulations take effect which require wood burning heaters to emit less than 2 grams/hour of soot. This new rule has given HearthStone the opportunity to take a leadership position and develop some of the cleanest, most efficient stoves in existence today, thanks to our TruHybrid technology.

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.
