Rocket Stove Water Heater // PART II // Initial full setup // Thermosyphon Issues

In my attempt to set up my Rocket Stove Water Heater I am having issues with getting the thermosyphon to start. I am obviously not an expert in this so am learning through trial and error. I am maybe being too ambitious with the length of pipe I am using.

Without much prior knowledge I am starting with what I would ideally like and working back to what turns out to be possible. Any constructive feedback on the technical side of thermosyphons would be greatly appreciated.
