I am doing full boils, which when I account for what I will lose in evaporation and break material, I usually start out with about 7 gallons in an 8 gallon stainless pot. Due to the size/weight and the fact that I am wanting to go to 10 gallon batches, I would like to relocate from the kitchen to the basement where I do my wort chilling, fermenting, racking and lagering. I am thinking my only viable choice is to go with a single induction burner. Does anyone else brew full-sized batches on an induction cooktop? If so, how long does it take to boil that much liquid from about 150 degrees, which my pre-boil wort is usually at after lautering/sparging? How many watts is your burner? Any further relevant info would be appreciated.
