Great, thanks.
Will get started on it tomorrow!!

Thanks, that was exactly what I was looking for.

There is only one question left - what inner dimension of the j-tube to use.
Same dimension all the way through, or smaller feed tube and burn chamber (ZeroFossilFuel).
Read about the smaller burn chamber several times, as it uses the venturi principle of speeding up flow and creating vacuum.
Using it to aerate my fish tanks and it works well.

This will only be a stove not a mass heater, as in the summer time it has to go, to make room for plants.
I was going to divert some of the water after the filter to run through the copper tube and back into the sump.
The pipe will be open at one end. do you still think this could still burst the pipe?

@Glenn
Maybe we should put your post into a PDF and make it a sticky at the top of the rocket stove thread?
Am sure I am not the only one scratching my head and trying to sort through all the info, where a lot contradicts itself.
I could just whack the stove together and see, but copying from someone's experience saves so much time and money LOL

Hi,

sorry for this question, but have been trying to find info on how to calculate the internals for a certain size tank for days, but just cannot find anything.
The Excel sheet that is linked on this forum does not come close to what I have.
Can you please point me to a link on how to calculate it?

What I have is a propane tank (1100mm (43") tall - tank only, 500mm (20") inner diameter)

The only internals dimensions i could find that come close to what I have is for a 38"x12" tank.

The stove I am build is for a green house with an aquaponics system (5500L/1453gallon).
The water is at 5C/41F at the moment and the fish are not feeding.
Will add a copper coil to heat water.

Thanks in advance.
