Mass heatn’ water heatn’ rocket heater

Hello friends. I’ve just purchased an old tiny house on wheels which is about to undergo serious renovative good stuff. Most notably a rocket mass heater. This mass will probably weigh about 2000lbs and will perhaps remove the portability of the unit. Anyone who has info on a lighter system will be thanked greatly. Anyway I’ve been playing with the idea of having my mass double as a water heater using pex runs through the mass. Also toying with “hot water on demand-ish stuff, this would include multiple shutoff valves and a gravity drain so I may open current and quickly dispose of or use it so not to over pressurize the system. it would be just awesome to 1, have free easily accessible hot water during winter and 2, have a partly emptyable heat storage unit. Perhaps I could empty the unit of water before driving and take 2-300 lbs off my load. We know water holds heat well. And the surrounding cob would keep the water warm for extended periods of time.

Has anyone played around with this idea? The main things that I’m hoping to gain information on are 1, the general heat level 1-4 inches away from a 5 inch rocket exhaust duct (the duct run exiting the bottom of my barrel riser) and how distance affects that Temperature. Also learning how to maybe not blow both myself and my dog up would also be key information.

I am new to the site and even newer to rocket stoves. Any and all information on the topic is appreciated! Happy days and sunshine to you all.

Welcome to Permies Dean. Take a peak at the lighter bench that Uncle Mud posted about here.

On top of spaghetti all covered in cheese, there was this tiny ad:
