The impetus of this project is to create a single unit that combines a functional cookstove with immediate heat production with an efficient firebox for prolonged masonry heat storage. We will draw from medium-sized “batch-box” development and use bypass dampers as switches to significantly alter the flow through the heater depending on the output desired.  An important part of the project will be to experiment with an open-source flow for project development. This project is being developed in the context of a hands-on workshop that will be realized at the Masonry Heater Association’s 2022 Annual Meeting.

Here is an initial volume concept:

A lot of work will need to be done to develop the technical interior or core for this heater as well as to develop a bill of materials.
