Anyone familiar with this eherms build? looking to build something like this with a few changes. First question, can I just add a pid controller and ssr to control boil without the adjustment dial on the digital ssr? Second question, is since this is a 30 amp service, can I use any 30 amp heating element? My thought is a 5000 watt blichman boil coil would be more efficient than the standard 5500 watt curved element being that it covers more surface area. Thanks for any help. I'm sure ill have more questions as I work my way through this.
