Everything you need to use your Zodi shower breaks down and stored in the hard plastic box with the exception of the propane cylinders.
There is a water pickup with an electric pump that you put into the water, with an attached battery pack that uses 4 D battery's. You can see the battery pack here sitting above the pickup / pump.
Setup for the Zodi goes something like this:
--Remove the burner from the box and attach 2 propane cylinders. Once attached the cylinders sit in the lid that acts as a base and keeps the unit stable.
--put the pickup into the water and start the water pump. Once water is flowing, light the burners.
--The burners heat the water, you take a shower.
--When you are finished taking your shower, turn the burners off and continue to let the water flow until it has cooled down.
--Turn the pump off, disassemble the unit and pack it back into its box.
While the Zodi did get the water a bit warmer than the Coleman, the setup and takedown process was the major negative factor for the unit.
