Alright...I have been thinking about this for months now. As of recently, I have been planning for a 2 tier structure with the HLT and MT utilizing a pump and then gravity feeding into the BK. I have began to get all the components necessary and then thought about direct fire MT with re-circ. but then thought about the weird set up with having to pull from the side of the MT (due to gravity feeding the BK) into the pump then back up to the top of the MT.
So...then I started thinking about single tier. To be honest though, I like the idea of only having one pump and would love to continue to batch sparge and control the mash out flow.
So, I am trying to gather opinions and really see if there is anything I am missing. I am starting to keep myself up at night thinking about this. ha. Any suggestions or opinions on 2 tier or single tier?
