Boilermaker Evap Rate

[Brewfat]

The wife got me a 10 gallon Blichmann Boilermaker for my birthday.
Awesome.

As I move towards my first brew with this, can anybody with one of these tell me what I can expect for evaporation in a 60 min. boil?

thanks,

i've got a 20gal boilermaker, but my general rule of thumb is 1gal per 60 min...probably come in just under that volume actually.

I would say 1 gallon sounds about right. I have been using a Polar Ware not a Boilermaker pot, but the dimensions of the pot is almost identical. I shoot to start with about 6.5 gallons, then I end up with about 5.5 gallons in my bucket.

A lot depends on how vigorously you boil the wort. My boil off rate is typically about 1 to 1-1/2 gph, however, I can get up to about 2.5 gph if I really crank the burner up full blast and maybe even more than that. Not sure as I've never run it full blast for an entire hour. I have boiled off 2 gph more than a few times when concentrating the wort though.

depends on a lot of factors - ambient humidity and temperature, altitude, burner (and how high you set it).

As a rule of thumb, I adjust my flame to hit 10-15% boil-off over an hour, regardless of which vessel I'm using at the time (I have a few to choose from). It's actually quite hard to get it down this low in the middle of the cold, dry winter - I've actually ended up boiling off 50% before, and that was considerably below max flame

I've been using a 6.5 gal turkey fryer and boiling off about 1 gal per hour. This was with a fan blowing across it to control boilover.

I was thinking the Boilermaker would probably be higher. I don't go too crazy on the burner, I'd call it a mild rolling boil.

I'm excited to use this thing as I'm also going all grain. I was doing large partial mashes.
My pipeline is completely empty now so I will be brewing a bunch over the next few weeks before winter hits.
