Our homebrew club, the Albany Brew Crafters, are planning on brewing a extract / partial boil batch at a local bar for Learn to Homebrew Day on November 3rd. I'm looking for a portable stand-alone type burner to boil 3 gallons of wort, and am wondering if anyone has any suggestions. I think it needs to be at least 1100 watts to get 3 gallons to boil, according to these calculations:
Water Volume (lb) x Temperature rise (°F) x 1 Btu/lb°F= Heat required
(3gal x 8.34lb/gal) x 150*F x 1 = 3496 BTU or ~ 1025 watts
Am I correct? And does anyone have any suggestions regarding burners? We'll most likely be brewing inside.
