Masonry Heater Core Kits

As the heart of the masonry heater, the core is critical for efficiently burning wood to allow you to extract the most heat possible from each fire in a safe manner. We offer heater cores to fit to meet your heating needs. All of our cores are produced of materials sourced, cast, and conditioned right here in the United States, and many of our designs have been tested for efficiency and emissions at third party accredited laboratories.  After selecting a core, please have a look at our Veneer Kits.
