Hello fellow HBT-ers.. Ive been looking at a Stout 1BBL/2BBL system and was wondering if anyone knows, or has used these systems.... and what is the requirment, (or source) used to bring to boil/HTL?...
Thanks, and
Thanks, and

I emailed John @ Stout and asked him about heating a 3bbl kettle, this is what he said:
You need at least 330,000 btus of heat. Assuming a 25% heat utilization, that will give you an 8%/hr evaporation rate. You could use two 220,000 btu Banjo burners or you can look at Tejas Smokers' website for some large burners as well.
Cheers,
John
Or go to Brewmation.com and they have an electric system they made for Stout kettles and tanks.

electric, gas fired, or steam?
to get from room temp (70*) to boiling takes 35k and 70k BTUs, for 30 and 60 gallons, respectively.
1kW of electricity = ~3400 BTUs
use that to figure out how fast you want to be able to heat the water. divide the BTUs it takes by the BTU output of the heater to get how many hours it takes to reach that temperature. (keep in mind, this doesnt account for heat lost at any point)
eg. 35,000BTU / 3400 = 10.3 hours for a 1 kW element to move 30 gallons of water from 70* to 212*F
35,000 / (3400*5.5) = 1.8 hours for a 5.5kW element to do the same...
if you want to use gas burners, using the above reference...
330k BTU @ 25% = 82,500 BTU/hr of real heat. that is equivalent to a ~24kW heating element, or 100A @ 240v. that is quite a bit of power.
there are plenty of ~1bbl systems out there that use 8-10kW worth of heating elements. more power just means that you will be able to heat faster. the bare minimum you can use is whatever the minimum power that is needed to maintain a boil, and for 1-2 bbl batches its probably something in the range of 3-5kW. though at only 3kW, its going to be painful waiting for 60 gallons to heat.
