I recently set up my brewstand with BG12's. During the first brew, it took forever to get 7 gallons of wort to boil - like 30-40 minutes. I expected better performance since I've heard that they can handle 15 gallon batches just fine.
I mounted them about 4 inches from my keggles to leave some room to raise them up if needed. Should I raise them? If so, how high?
