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

This BB requires you to perform the annual ash cleanout of a rocket mass heater.

Some threads on doing the ash cleanout:
  - Ash in Rocket Mass Heater
  - Ash Cleanout
  - Cleanout Time
  - and please read the RMH Forum for general information and ask question

It highly recommended to watch the Care and Feeding of a Rocket Mass Heater video.

Cleaning Out a RMH

  - 6 pictures
       o pic of rocket mass heater
       o pic of ash in general barrel area
       o pic of general barrel area with significantly less ash
       o pic of ash in ducts or stratification chamber
       o pic of ducts or stratification chamber with significantly less ash
       o pic of restored rocket mass heater
  - 2 minute video of starting a fire in rocket mass heater after cleaning with no smoke coming from cleanout points

Get ALL the Ash!


I'm using an Ash Vacuum, and cleaning the Rocket Mass Heater in the Fisher Price house at Basecamp. Everyone agreed that it'd been over a year since its last cleaning. I got so wrapped up with things, that I forgot to get a good picture of the manifold covered in ash.

Thanks for the reminder Lee!  I cleaned out the red cabin's batch box heater when I was at the PEP1 event.  It wasn't running very well so I broke loose the elbow per Paul's suggestion and found it nearly completely blocked off with ash.  So I replaced it with a "T" and cleaned out the vertical stovepipe.  I vacuumed out the side port and scooped and vacuumed out the batch box.  After doing that it drafted much better and didn't smoke out the door nearly as much.  It was still a tricky stove to keep from smoking but it went from impossible to reasonably possible after cleaning.  

I started the video with the kindling fire going.  I pan around to any spot where smoke might come out, then open the door and load the batch box up for the night.
