Hello All, I am in the process of designing a Rocket Mass Heater for our 30’ yurt. I have built several batch box style RMH based on the design created by Lasse Holmes, using angle iron to create a rigid form, as well as give something for the door to hang on. They have all worked really well, but I am sure there is room for improvement and added efficiency. I would also like to use the door sold by Firespeaking ( www.firespeaking.com/product/k404-firebox-door/ ) which would create a slightly taller and more narrow fire box then I have build in the past.
My two main questions are, can anyone point me to any resources discussing the pros and cons of the different size or shape of fire boxes for a front loading, batch style RMH?
And how do folks recommend attaching the door if I do something different and dont use the angle iron frame?
The angle iron frame also provides the strength and ability to make an arch of the top of the fire box with fire brick, and curious what other people use for the top of the firebox, that isn't too expensive. Thanks!
