I've done about 6 brews with my herms set up and i am struggling to keep a steady temp, i am getting a fluctuation of about 2.5 deg. i have changed my heat exchanger from a 10L pot with 15m copper coil & 1500watt heating element to a 3L tube with 5.5m(i think) stainless coil and 2000watt heating element. I'm not to sure which is better.previously i had the temp probe @ the outlet of the heat exchanger now i have it in the mash tun. I'm using RoHS digital temp controlers for my mash and sparge. I suppose my question is what can i do to steaddy my temp and keep it more stable and consistent?
