I know talking about btu's has been done on this forum over and over again, but I have a specific question. After reading a lot of the previous forums about btu's I have come to this conclusion, and want to know what y'all think. This burner combo comes with a 30,000 btu, and a 60,000 btu burner. I brew at the most 7gal to finish with 5gal batches. I was think the 30,000 btu burner would be good for the hot water tank because I don't have to get it to a boiling temp, and the 60,000 btu would be good for the boil. What do y'all think?
