I'm looking into going electric, the only reason being ability to brew (biab) indoors. I'm not sure yet what PID and SSR means, but say I'm going 240v, can I simply have a control box with master on/off, element on/off, and a variable output for the element? This means no setting mash temps or timers etc. Element is simply "replacing" propane as my heat source, and I'll be using the analog brewmometer on my pot to monitor temps, adjusting the element accordingly. Has this been done, anyone use it and are happy with it?
