Double doors provide a wide view into our largest zero clearance fireplace. The textured cast iron facade adds a uniquely HeathStone touch to your living room.


Zero Clearance Fireplace

Clean burning and efficient

Our ZC wood fireplace exceeds 2020 EPA standards. It burns cleanly and efficiently to keep the heat in your home rather than wasting it up the chimney.

Cast iron design

The cast iron front of the WFP100 is designed with a hand chiseled stone texture that offers a uniquely beautiful finish to your fireplace.

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.
