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 …
Ever looked at the fireplace in your house and wondered what useful function it serves anymore? Why not cook with it! Especially in the shoulder seasons when it’s not quite warm enough to BBQ outside, cooking in your fireplace is a wonderful way to increase the fun and coziness factor while getting dinner on the table! Cooking with fire is definitely an art, and one that is mostly learned through experience. So let’s get started!
Here is an email that I recently received from a client that explains a situation that other new masonry heater owners may experience: Hi Max This thing happens that I want your advice on. Occasionally when we fire the stove, we get a lot of smoke in the room during the first 10-15 minutes of …
Although a bit outdated, here is a comprehensive firing guide for masonry heaters put out by the Masonry Heater Association of North America:
A synopsis of codes and standards for masonry heater construction, including information regarding their efficiency for home owners and building officials.
We have put a lot of effort into developing additional hardware to complete our catalog of hardware for masonry heaters. Since we have been custom masonry heater builders for almost 20 years, we know how helpful it is to be able to count on all the hardware you need for a project.
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.
