What You’re Buying
The HeatKit core is the internal combustion and heat exchange system of a masonry heater.
It is not a finished appliance. Each system is built on-site by a skilled mason using brick, stone, or other masonry materials. This allows full customization while maintaining the performance of a proven system.
Core Features
• Clean-burning firebox
• Proven heat retention system
• Long, steady heat (12–24 hours per firing)
• Efficient wood use, low emissions
• Flexible layouts
• Developed in North America through decades of testing
What’s Included
A traditional white bake oven above the firebox. Flames do not pass through the chamber, allowing clean, even cooking from stored heat. Ideal for bread, pizza, and roasting.

Custom Finish
Each heater is built and finished on-site. Common finishes: brick, natural stone, or plaster. Every system is unique to the home.
