So I'm renovating my whole set up and going to add a heat exchanger to my HLT to regulate my mash temp. Pumping the wort through the heat exchanger and back into the mash tun. I'm sure if you clicked on this topic you already know what I'm talking about, but just in case there it is. My question is how big of copper tubing should I use? I know 3/8th is standard but would bigger tubing be better? Would longer be better? What does the brew give have to offer me?
