Hey, Scott !
I've been lurking on your blog since you started posting.
Your design had a big influence on the brew sculpture I'm about to build.
I'm using an inline hot water heater to supply my strike and mash out water directly. No MLT.
I'm setting it up with 1 tippy mash tun and 2 boil kettles, so that I can be doing 2 boils at once.
I'm thinking that I can get the mash tun cleaned out and the second mash going before the 1st boil is done and then chill the first boil while the 2nd mash is recircing.
But depending on the boil times, I might be sparging into the 2nd kettle before the 1st boil kettle is done.
I thought about having 2 tippy mash tuns and 2 boil kettles but thought that was overkill. I think I can make due with 1 tippy MT and 2 boil kettles.
I'm setting up to brew small batches. I want to brew small batches of many different beers every year. 11 gallon vessels for 6 to 8 gallons into the fermenters. If I want to brew a big batch, I'll do 2 mashes and 2 boils back to back and dump them into the same fermenter. Its a bit more work, but I then get by with smaller equipment and more versatility.
I'm putting PID controllers and gas valves on all my burners.
I'm also putting a removable chute behind my tippy.
As soon as the 1st mash sparge is done, I want to put the boil kettle on auto pilot, dump the 1st mash, add the strike water, put the mash tun on auto pilot and add the crushed malt. Bing, bang, boom.
We'll see how it works in reality.
You and your setup were what convinced me I should be shooting for 2 batches per brewing session.
Thanks for taking the time to document what you did.
