Long-time lurker, but I registered to ask a question or two. I'm looking to build a really tiny, pretty mobile home. The summers here are excruciatingly hot, and the winters are as cold as the Fortress of Solitude. I like the idea of both rocket mass heaters and rocket stoves, but I don't need a lot of mass in a heater, and I'd really don't have the floorspace for two separate installations.
1.) If I put my mass directly around the barrel of the RMH, will it be "good enough" to heat a small space? Or would the difference be negligible enough that I could just leave the M out of my RMH?
2.) Is there any way to heat the ovens (in red) with the exhaust from the rocket stove that drives the cooktop (green)? I can always give the ovens their own exhaust and treat them like a traditional pizza oven, but I'd much rather reuse as much of the heat as I can.
