This is a progress report to let our community know what we have been working on. At the heart is a modular approach where the firebox, the heat exchange design, and options like adding an oven are independent of each other so that each can be developed and documented separately and then combined for each […]

This year’s Masonry Heater Association (MHA) Annual Meeting held in April in Little Switzerland, North Carolina, continued the tradition of bringing heater builders together from North America and around the world to share in the techniques and processes of masonry heater and wood-fired oven construction. Here are some highlights of the innovative work and great

Conceptual Plans The basic pattern of this heater is called a Contraflow which sees the combustion gases leaving the firebox and splitting into two symmetric downdraft channels before joining in a manifold in the bottom courses and making there way to the chimney. We made a custom 4″x8″ pivoting damper to allow for an operable

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.

Progress is made painfully slowly by isolated individuals and small artesan companies each having to invent and build the wheel themselves. To the extent that each can make contributions to the overall body of knowledge and benefit from the shared resources that result, it might be possible to gather more momentum for this interesting and resilient technology. This article explores the potential for an open-source approach in masonry heater design and construction.
