This is my set up. It’s a two tier rack to make use of gravity for the sparge and one pump for everything else. The top tier is a 10 gallon HLT that sparges into another 10 gallon MLT. The pump is used to recirculate the wort and to move it to the 15 gallon boil pot. The 2nd photo shows some of my accessories – pump, plate chiller and decoction pot.
