They move the grain from the Mash Tun to another vessel to sparge it? That seems weird. I could see using the HLT (hot liquor tank) as the boil kettle. That's what I do. Heat water in the HLT, mash in a cooler, collect runnings in another cooler, batch sparge in the mash cooler where the grains are already sitting there from the mash, collect second runnings in the extra cooler, then transfer wort to HLT which is now a boil ketlle.
