Yep just heat and stir. Pretty easy. The temp goes up pretty quickly.
I should carefully consider this new setup to allow for direct heating of the MT.
Right now I'm 100% gravity. I start with my SQ14 up on a platform with my BK on it. I heat the water, drain into my MT which is on a slightly lower counter. while I mash I move the SQ14 down to the floor next to the counter so I can then drain into the BK from the MT when mashing is complete. So right now I can't accommodate direct firing my MT unless I also used it as my BK.
this might mean I'd need two different hoist locations. one for when I'm mashing and boiling in my 20 gallon MT and one for when I'm using my setup like I do in the description above (separate BK and MT vessels).
