in using the biabacus i was noticing the boil off seemed a little high with the dimensions that i put in. The keggle i am using is a euro size which is a 50l. The dimensions that i used were 38 cm diameter and 43 cm depth the cut out for the lid is 30 cm. According to the biabacus the boil off would be 7.28l for a 90 min boil. Any thoughts if this would be right or if you use a keggle what kind of boil off have you been experiencing.
thanks in advance to any and all that may be able to help

Hi there kitch,
Unless you get an answer from someone with your kettle that lives in your area, I'd stick with using the 38 cm number for your first brew at least. It will probably be correct to within a litre. Your evaporation rate can also change a lot from brew to brew especially if you brew outside so don't be surprised at this.

Correct PP! Altitude, ambient temp, ambient humidity, surface area, vigor of boil, etc, all factor into the boil-off rate.
Kitch, I would reccomend that you guess "high" on that number (the boil-off rate) as you can always add back a bit of top-off water at end of boil if you fall short. Keep good records (actual boil-off amount, ambient humidity and air temp) and eventually you will not only dial in on the proper rate for your rig you will also be able to compensate somewhat for environmental variables!

thanks for the advice guys. I was probably leaning to trusting the biabacus but as with anything new and different you just have to ask.
And just a special shout out to PP not only for the amount ouf work here on the site but for where you live as my niece spent a few years in Perth at the university doing her masters and the pictures she sent along with the stories she told it is definitly a destination for my wife and i to visit
thanks again all
PS Could you post some sunny warm weather for me to download as today here it is calling for 15 - 30cm of snow

FWIW, I use a 58L keggle and boil off 6L/hr, so 9L for a 90 minute boil.

I just remembered this thread What is your evaporation rate?. There's a few keg numbers in there.*
Maybe Leafman66-67 can bump it with his numbers above? It needs a bump
. (You need to post your kettle diameter though as well. First post has the details.)

* Warm weather coming to you via a PM
. Cheers!
