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.

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.

Precision Steel

High-quality steel components are formed using the most modern processes available to achieve the highest level of fit and finish.
