Cookstove + Masonry Heater Hybrid

March 7, 2022 / 34 Comments / By Max

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 â€œbatch-boxâ€ development and use bypass dampers as switches to significantly alter the flow through the heater depending on the output desired.Â 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 Associationâ€™s 2022 Annual Meeting.
