In Ianto evans book, he says that it is possible to have one venting through the wall. I don't know anybody who has been happy with a rocket of any type vented through the wall. They're really prone to extreme smokeback.

Okay. This means I will probably place this in the main living area, where there is already a fireplace and chimney.  Is there any chance I could build this with a different topper, that wouldn’t look like a stovetop, but would still allow me to cook if I wanted to?

A complete build, if everything were purchased as opposed to salvage bricks and materials, would run about $800 by my estimate.  That does not include chimney, which yes, should be a regular chimney, venting up above the roof of the building.

Matt, thank you for your work on this!  Since this is a rocket mass heater, is it absolutely necessary to have a chimney that goes above the roof line?  I could be wrong, but I thought I read somewhere in a permies.com thread that the exhaust of a RMH (being composed of steam and carbon dioxide) could be vented straight through the wall.  That would be ideal for the location I have in mind for a RMH.  I’m not trying to be difficult...well, maybe yes I am. I just want to install one without attracting attention in my suburban HOA burdened neighborhood - where my husband is content and not willing to move away.   Thanks in advance!
