This is a badge bit (BB) that is part of the PEP curriculum. Completing this BB is part of getting the straw badge in Rocket.

This BB requires you to build a J-Tube Rocket Mass Heater.


These are some potentially useful resources:
  - The Rocket Mass Heater Builder's Guide by Erica and Ernie Wisner
  - Top Questions About Rocket Mass Heaters
  - New Build - Need Help
  - Building My First RMH (Tommy's Tea Dome)
  - Farm House RMH, First In House Build

This is a potentially helpful video on building a RMH.

Building a Rocket Mass Heater step by step to finish! Watch to the End!!!

To get certified for this Badge Bit you must provide:
  - pic of area before build
  - pic of core (exterior of burn tunnel, heat riser and manifold) without barrel
  - pic of ducts or stratification chamber before mass
  - 3 pics of manifold
  - pic of completed product
  - pic of vertical exhaust going into the ceiling
  - pic of vertical exhaust coming out of the roof
  - 2 minute video of starting the fire and proving there are no smoke leaks
