Clydesdale

About the Clydesdale

HearthStone’s classic fireplace insert. Full cast iron construction, soapstone lining, and TruHybrid™ technology make this insert top of its class.

Clean-burning, highly efficient, and easy to operate, the Clydesdale uses our TruHybrid™ technology. Engage the catalyst and turn your stove down for slow and efficient overnight burns. The Clydesdale’s large open window lets you see as much fire as possible. Enjoy the ambiance of a fireplace and the efficiency of HearthStone. Burn up to 24 inch logs in the soapstone lined firebox. Soapstone retains the maximum heat from your fire and radiates steady warmth as your insert burns.
