You guys got it. I think that reducer may be missing from the BOM here. It *is* in the parts list I sent to BYO. I believe they're going to be doing an on-line extension to the article at http://www.byo.com that will include it.

Got my issue of BYO yesterday in the mail.
Nice article, though I found this thread more useful (though quite a bit longer).

Thanks Baron ken. As is normal in publishing, quite a bit of detail got edited out. I'm hoping BYO will cover more of the details online when they post the materials list.

Dayum my friend! Just got my BYO today. Most excellent article! (And not because you mentioned my name!)

I am very humbled my friend, and thanks! This is very much your system!

You have gone to a place where I (and a lot of others) have been thinking for quite some time. Small batch brewing... As I started in a small apartment and then went to big batches, I have been working toward smaller batches too... Although I don't have the (lack) of drinking problem you have! A small batch could last me maybe a day? I miss experimenting sometimes, but I want to do it with all grain...

Excellent system bud... Gotta have a beer one day!

I'm still debating on whether I want to scale this system up for 5 gallons; if I can do it with a single 120V element (2000W), then it's a no brainer. If it's going to require multiple 120V elements or a 240V element, then that makes my decision much harder since it will introduce some logistical problems.

I've read every thread I can find on electric MLT / BK and some people indicate that 5 gallon batches can't be done with a single 120V element. However, the "Electric Heat Calculator" spreadsheet that has been referenced a lot indicates the following:

Heat 5 gallons 60F to 155F w/ 2000W = 37 minutes
Boil 7.5 gallons from 170F w/ 2000W = 24 minutes

These numbers seem reasonable to me. So, any thoughts or advice from JK or others?

Glad ya liked it Lonnie. I had a couple of quotes in there from you that sadly hit the editing room floor, but I was pumped they added the reference to your 10 build. Next time you're in CO, the beers are on me.

5 gallons is quite doable, but that's starting volume. I get a good rolling boil with 5 gallons in my 120V 2KW kettle. After a 2 hour boil (max I ever envision doing), I'd end up with 3.5 gallons of finished beer.

Now, if you want 5 (or more likely 5.5) gallons of finished beer, you'd be looking at starting the boil with upwards of 7 gallons. Without some serious effort at controlling heat loss from the kettle, I really don't think a single 2KW element will give you a good boil on 7 gallons. POL, our resident electric brewing guru, may chime in, but I believe he'll have the same opinion. A weak boil can lead to some seriously disappointing beers (as anyone who's pushed their kitchen stove to the limits knows).

JK is right on. After some experimenting and a lot of "Pol" reading on here, a 7 gal boil with one 2KW element will not cut it. I built my clone with two 2KW elements and it will give 7 gallons a rip roaring boil. I plug my second element into a separate circuit in my kitchen for the boil and throttle the other element in my PID back to 75%. This gives me 3500W for my full boil.
