Hello all!
I wanted to follow up on this thread and share with you a photo of the prototype that was built based on the design development chronicled in this thread!
The build was the outcome of a workshop that I led at the Masonry Heater Association Annual Meeting in 2022.
It features a batch box style firebox with the ability using valves to completely switch the direction of flow either into the main mass including the bake oven and heating hot water, or reversing it so that the flame hits the cooktop. One is able to control the amounts of primary and secondary air supplied in both configurations. I intend to add details of this to this thread soon.
I am returning to this project to continue work on it and have several offers for you to support it.
I have put all of the drawings together that I made to build this heater as a set of plans which are for sale (and on sale during November)!:
