Unpressurized rocket hot water system - plumbing.straw.rocket PEP BB

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

In this Badge Bit, you will build something truly amazing - a rocket powered water heater!  Not a rocket fuel powered one, one that uses twigs!  

There are many approaches or styles to do this, just be sure that it's unpressurized so that if you accidentally boil the water it doesn't go BOOM and you don't go SQUISH.  There is a matching BB in the Rocket badge that you can potentially claim for this project (Rocket Water Heater in the Rocket Badge).

Here's one style described by Geoff Lawton:


To complete this BB, the minimum requirements are:
  - construct a water heater
  - powered by a wood fired rocket heater
  - unpressurized water vessel in contact with the heat
  - can be batch or continuous flow
  - must be able to heat 5 gallons of water in 30 minutes or less to 140F

To show you've completed this Badge Bit, provide proof of the following as pics or video (less than two minutes):
  - the existing location before you start
  - the bulk of the parts you're starting with
  - 3 stages during the plumbing/vessel/piping construction
  - the completed construction
  - cold water going in [timestamp]
  - 5 gallons of 140F or greater water coming out in under 30 minutes [timestamp]
  - description of how the water heater works
  - description of how you have avoided any chance of Boom-Squish
