The goal of this design project is to create an extremely efficient and clean burning unit that combines the functions of a cookstove with prolonged masonry heat storage.

The design features an extremely efficient firebox which provides adjustable primary and secondary air in both burn configurations. The design also includes options for an oven, heating hot water, and adding a heated bench. It’s has been nicknamed the “mothership” because of the way


As far as we know, this is original design work and here are several ways that you can support this project:

Or you can purchase hardware individually!…

The project draws on medium-sized “batch-box” development and uses bypass dampers as switches to significantly alter the flow through the heater depending on the output desired. 

An important part of the project is to experiment with an open-source flow for project development.
