I am in the process of my RIMS build and would like to add a heat stick outside the MLT for step mashing......my original idea is to make it from 1" copper using a 110V element. I dont have 220V acess were I brew. Will this be large enough to raise temps from 120 to 140 to 155 while recirculating? Should I use larger diameter copper for increased volume? I do 10g batches. Any ideas, pictures, advise?
Thanks in advance.
