I plan on building a brew sculpture and have been doing a lot of research and I started looking at electric brewing because it really interested me. From all the stuff that I've read it seems like you need to have 240v for your system and I'm trying to find out if that is pretty much true. If so I think it would be to much of a pain/cost to get 240v into my garage, and I'm no electrician. Are there any feasible 120v systems because if there aren't I'll probably stick with gas. Thanks.
