Your not just buying a plan you are buying a master builders personal advice while you are building!
I can tell you that Matt is one of the friendliest most helpful people you would ever want to meet!
His plans as they are sold do not have enough water storage. He has talked about it during stove chat (Wednesdays at noon mountain time) @ broaudio on you tube
He said a larger storage tank could be utilized with his heater.
I suggest you contact Matt directly and ask his opinion.
I agree with Danial that your barn system should be separate.

Was wondernig if anyone had tried using some sort of synthetic oil to extract heat from the rocket stove and then transfer that hot oil through piping to a water thermal mass.
Seems it would eliminate the issues of water-related corrosion and also the potential for steam explosions. Presumably, with a large enough thermal mass, the temp changes would be gradual enough that you would have plenty of warning before you got close to boiling it off.
Another benefit is the oil system could be mostly closed (probably needs some capacity for expansion) so air would be kept out to prevent oxidation.
Downside would be a small leak of oil into the stove could be bad.
I believe automobiles are running temps at least in the 250+f range with conventional motor oil and that's already 40F above the boiling point of water without going with any exotica.
Is that something anyone has pursued?
Edit: off-the-shelf Mobil-1 synthetic can supposedly be run at 500F. Definitely not a cheap product, but it seems to indicate this might be an avenue worth pursuing.
