Brewers, I just made a heat stick using all stainless triclamp piping. Pricey, yes but it works awesome and is safe too..double bonus. One question; I would like to purchase a controller like the Johnson A419 to control the temperatures of the heat stick. I'm using a 1500 watt hot water heater element and would like to set this up so my mash water is at 170 F. when I get out of work. What do all of you electric brewers recommend? Thanks and Cheers...Simie
