i am revising my plans here. I have 3 - 10 gallon pots, 2 burners. I am now set on building a rims tube to control my mash temps. My plan is to have one burner for the HLT, the second for my boil kettle. Should i plan on a 3rd burner to get my mashes up to temperature a little quicker or do most of you jsut use the rims tube to bring the heat up for mashout?
