My current wood stove has a 6 inch pipe running 18 feet up. I have heat sheild on to meet clearances required by code for being near the wall.
I want to build RMH to be the main heat source for my small 24x24 strawbale house.
With the CSA needing to be consistent I understand that a 6 inch system has to have a smaller feed box. Im a bit worried about this being to small and less practical then the bigger feed with an 8 inch system. Also, since this will eventually be primary heat forbthe house I need it to be able to warm up the house very well. I want the option of making the house too warm then needed.
Building an 8 inch rocket stove means changing all my pipes and insulated chimney and new heat shield which adds a lot of costs to the project.
From people with experience using RMH, is an 8 inch system worth it even with additional costs or would a 6 inch RMH using existing chimney be enough ?
Hi Joel, and welcome to permies. What part of the world are you located in? How cold are your winters? Is that 24x24 feet or meters?
If you're not in a super cold winter climate and that's feet, a six inch CSA RMH will heat a well-insulated straw bale dwelling brilliantly.

Hi Steve, Thank you for the welcome. Im in Quebec Canada so our winters are pretty cold. The house is 24x24 feet with interior dimensions being 21 x 21 feet with two lofts above and cathedral style ceilings. Even tho it has a small square footage the house has quite a bit of space to it. I have in floor radiant heating and off a propane boiler and plug electric radiant heaters but im trying to move away from those.
So I left, I came home, and I ate some pie. And then I read this tiny ad:
