Little background: I currently have a 2 burner stand, each burner has a 10 psi adjustable regulator on it, that I hood each to a separate 20 lb tank. The burners are typical 10" banjo burners. They are firing under keggles, and I typically brew 5 gallon batches, although I may possibly jump to 10 gallons in future. I am trying to get away from portable tanks, as the closest place to swap or fill is over 20 mins away from my house each way.
I am trying to figure out how to plumb my brew stand for LP propane. I am going to keep manual control vs automated. The main goal is to hook up to my house supply of propane. The second option would be to have a second tank for HP propane ~ 20psi.
I currently have a QD connection in my garage for the LP propane. It is supplied by the main tank at 11" WC. From there, I was considering using a 1/2" QD hose at about 24' so I can brew outside most days. I have ordered the LP orifices from Brewers Hardware here and these needle valves from Bayou Classic. I was planning on using 1/2" black pipe on the brew stand, and control the burners with the needle valves. After looking at pipe sizing charts, 1/2" pipe at 30' is good for about 160k btus at 11" WC, or roughly 80k at each burner. I hardly run both the HLT and BK wide open at the same time.
The second option would be to get a 100 lb propane tank, and run a 20 psi 1/4" QD hose to the brew stand. The supply would then be split and connected to the original 10 psi regulators I have for each burner. It looks like using a 1/4" hose at 20 psi would supply more than enough gas to run both burners, especially since each burner would be stepped down to 10 psi, but to do this would require a second tank. However, I can't really confirm this as I haven't found a chart online other than 11" WC charts. I could have the 100 lb tank filled with the regular house tank.
Would it be best to run the stand at 11" WC, or at 20 psi? Is one option inherently better than the other? Am I missing another option?
