I gave a 7.5 gallon SS brewpot with a thick tri-clad bottom that I use on a NG stove. I never really get a good boil. Its about the same if I boil 4 gallons or 6, so Im wondering if I loose some heat through the thick bottom. Do you folks think I would get a better boil by using a pot without the tri-clad bottom? Something like the Boilermaker?
