I really dig the idea of electric brewing, maybe I will convert that direction some day and ditch the propane.
If/when you switch, I think you'll really like it. My only "regret" (if you can call it that,) was not going to full 240V. Unfortunately, the cost of extending that into my garage would have been prohibitive, so I used the 120V/20A circuit I already have there. The downsides are longer to heat and not a very rigorous boil, but it's quiet, clean, compact, and very easy to use. I just added a digital thermometer to my control box to monitor the mash. I hope to use it soon (brew day today called off due to Mother's day and didn't want to offend/irritate SWMBO.) I got the idea from SteelManCM in this thread.
