In the summer of 2023, we provided Philip Godfrey of Quebec, Canada with design services and hardware for the masonry heater he was planning to build. Philip was a DIY homeowner who had done a lot of research on masonry heaters and brought a wealth of industrial design and manufacturing experience to his project. He came up with his own version of the 5-Run Masonry Heater Plan.
Especially interesting are his solutions for being able to regulate the amount of primary and secondary air to the firebox via some custom air registers he made:
For those interested, you can study a powerpoint he has provided of his build which shows his innovative build:

Hi all, the way the forums re-post the original post still needs some work. The images showing Philip’s innovative castings are missing and the product options are vastly over-emphasized… apologies.
I am re-posting the images here so they can be referenced in discussion:
Huge gratitude to Philip for being a customer willing to engage in the open source process with these contributions.
Max, are the cast refractory pieces in this build something that Phillip cast himself or were they sourced elsewhere? And is there any more detail (other than the images in the PPT) of his damper system? Thanks!
Phillip formed and cast those pieces himself, and there is no more detail than what is documented here and in the original article. That amount of skill and process from someone who is not a dedicated professional in the field is very impressive. I worked with him some on a consultation basis to review his plan.
We are working on a series of cast core components we hope to get to market soon to help make masonry heater core building simpler so stay tuned.
