I know there are a bunch of these threads already posted, but I've found the other eBIAB builds so helpful I felt compelled to give something back. I've been brewing for almost one and a half years. I've done lots of extract, partial mash recipes and around six all grain batches. I moved into a new home and given the amount of water that tends to get everywhere on a brew day, the wife and I decided our hardwood floors probably wouldn't appreciate it. I've therefore been given approval by the CFO to start a new brew system in the garage.
One of my biggest challenges with all grain brewing has been properly hitting my mash temps. Even with a cooler (hey anyone want a 10 gallon mash cooler with bulkhead?) I tended to yoyo around my mash temps. I wanted something that allowed for more repeatably and would allow me to brew more often. So, electric control seemed like an obvious first choice. I'm also somewhat space limited in my garage so a three vessel system wasn't going to work. Therefore BIAB seemed like a good compromise.
My goal for this system is to have a 11ish gallon system with easy temperature control, a small footprint, and keep costs reasonable while adding in a few bling touches here and there.
This is my proposed wiring diagram (PJ I shamelessly stole from your diagrams, thanks for your help):
This is a quick mock up of the control panel:
Let me know what you guys think, or if you have any suggestions. The UPS and FedEx men have been busy at my doorstep, so I'll have pictures posted soon.
