Propane burner question

[Likebull]

So I am finally getting off the electric stove and moving on to a propane burner. It was taking way to long to achieve a rolling boil.
So basically I was wondering if one propane tank is enough to achieve a full length boil or should I have a back-up?
Ill be performing my mash inside and the boil outside and it is a 54000btu burner.

if you're tank is full, you shouldnt have anything to worry about. it's the next couple of batches that you have to start worrying about it.
it's always good to have a spare on hand though.
you never know when you'll forget to check your tank, and end up running out of gas as the boil starts. ask me how i know

If you have the ability, weigh it (full) beforehand and then again after your brew day to get an idea of efficiency. I have a Blichmann and was burning more then I was happy with (but ridiculously quick boil times) until I adjusted the flow and air damper.

Blichmann is convenient in that you can tweak things to get the most burn for the least propane but not all burners have that capability so that's why its nice to measure before and after so you know what to expect from your particular burner. I really don't see a problem getting at least one brew day out of a tank though.

I can get 4+ five gallon AG batches out of one 20lb tank, and that includes heating both the HLT and the boil kettle. If you're only doing a kettle you should be able to get through 5 or 6 as long as you're not getting crazy with your boils.

Awesome guys. Thanks. The last thing I wanted was to run out of fuel half way through my boil.
I wish I could afford a nice Blichmann.

About 10 minutes into a boil I ran outta gas. I was already a couple beers in, and my wife wasn't home for another 30 minutes to give me a ride. I had to wait it out, and be paranoid about where I needed to pick back up. The beer turned out alright, so I must've guessed alright

I generally make sure I have another at least partially full tank around before I start brewing for just that reason. Ran out halfway through a boil one time, had to borrow a tank from the neighbors at 10pm one night to finish. Not interested in making a habit out of that.
