Hello! Had bought this from u via japan yahoo auction! Wanna know what will be the best height for the pot stand if I would like to achieve best efficiency?
Need to capture more heat. Would not be surprised if the 150s boil time would become attainable if the water vessel were replaced with something akin to a JetBoil. Modifying a thermos to send flame up inside the double walled body might also capture enough more heat to speed the boiling process; hole in the bottom to allow flame in, holes around the top perimeter to allow flow up and out.
The optimum height from top of burner to bottom of pot should be 2 inches to give best boil time with less fuel. Your pot stand should be at least 1/2 the height. If you take 3 rows off from the top of the pot stand it will be perfect height.
