So I'm working on designing an all-grain, all-electric set up but I'm doing it slowly because of budget. I have the BK (got a great deal on a 26 gal from Morebeer) and would like to get started right away with extract brewing (5-10gal) to build my skills while I aqcuire the rest of my equipment. I plan on putting a 5500w 240v element that I plan on running off of my dryer outlet (30A) until I get the brew room in my basement built and wired. So my question is do I need a controller to do extract with a BK? I plan on using a BCS eventually and using schematics from P-J and designs from Ohio Ed, etc (so many good resources on this forum). Is there some sort of very basic equivalent to a dimmer switch that I can use to control the boil or do I even need to worry about it with just extract? I saw someone discussing a heavy duty light switch but rather than on/off I would like to be able to dial it down if needed. If the consensus is to build the controller than that's what I'll do. Like I said I just want to get started right away.
