I have a 1000 sq ft 150 year old post and bean shop that I'm humping butt on getting insulated for the winter and I'd like to heat with a RMH. I also have large amounts of waste lumber from construction projects as well as a significant amount of deadfall.
I have spent a lot of time reading and watching videos and I appreciate the experimental designs and ingenuity that I see but I do not have the time to experiment. Winter is coming and I have many projects on the go.
I'm looking for a proven design that can take 2x4's preferably. Is there such a thing?
I burn a ton a end cut 2x material. I built a batch system instead of the j pipe style to handle all my scrap. Burns hot as long as it's dry.

Nice. I was aware people are doing it but documented systems or well proven published designs are not that common. I see the DVD packages that people are selling and I'd buy one if it came with something approaching blueprints for a well seasoned and documented design.
How long you been running it? In your opinion is your system something that would be worth me replicating?
Steve, all the available documentation about batch boxes is to be found at http://batchrocket.eu/en/. If you want something different than the presented designs you either spend some time to discuss your requirements or you could design your own based on the documentation.
The standard RMH design as presented in Ernie & Erica Wisner's new book "The Rocket Mass Heater Builder's Guide" can easily handle 2x4 scraps as well as regular firewood. You just need to cut them all to appropriate size (generally less than 5" across for an 8" system). E&E also have published proven designs on their website http://www.ernieanderica.info/.

thanks, found a lot more info on batchrocket this visit vs previous, not sure why. I might go with an airtight this winter and get an earlier start on the project for next season.
