6000W heating element would be 1500W on 120V power. P = V^2*R, with R constant.

Oh and good luck, this could be a fun project.

So let's talk about the tank.

1st pic: The bottom of the tank has 2 ports. one simply goes out the bottom, the other is a tube that goes all the way to the top for "percolation". Eerily, I am seeing some Speidel Braumeister Potential: http://www.speidels-braumeister.de/i...4a2q5vhs766ka5

2nd pic: You're looking at the top. These are simply barb fittings, one would grab the steam off the center percolator tube, the other is for filling (I think).

3rd pic: This is the tank in a top to bottom view.

So here's some pics of the grime. It was caked for the most part in dirt, coffee residue, and grease. Not to mention the horrendous scale in the tank.

I'm soaking the tank and element in oxyclean overnight. Everything else came out tremendously clean with a light oxyclean scrubbing and a hosedown.

Ahh the fortunate few!

Great find Steve - can't wait to see what a soak does to that tank.

And what might you ask, will I be doing with this? WELLLLL, I've been building a 10 gallon single vessel brewery that will run off of 220v: http://www.homebrewtalk.com/f11/sing...rewery-158608/

And I've really been wanting to do something smaller and more convenient, but my funds are low and I need to actually finish a project

So I've pretty much got what I need here, I'm thinking about:

-How to do a mini BIAB system
-Or even create a mini Speidels Braumester setup
-Chiller would be a copper coil wrapped around tank and covered with reflectix. Inlet and outlet would be fitted neatly into the side where it could hook up and discharge into the sink.

Space is at a premium, I've considered even having a tall narrow mashtun sit on the front where the pot would be, and then do something similar to what JKarp did with his CB20 system: http://www.homebrewtalk.com/f51/coun...s-20-a-131411/ I could even use the small warmer plate to keep the mash warm.

So what do you all think? I'd be interested in hearing your ideas before I put it all together...this forum has a wealth of knowledge. Time is at a premium and I am funding my main rig right now, but I want to keep my eye on this project. One good thing is that parts for this can be sourced cheaply and easily, I already have all the main parts except for a temp controller.

Very cool find, this should be interesting. The 3 gallons is going to limit you out of BIAB, so you will likely need a second vessel. I would want to integrate (ie, hard wire) the chiller into the system somehow, my mind is turning.

I hear you on the BIAB thing. I'm interested in what people come up with, because right now I'm thinking about plopping a cooler on the front.

Maybe a chopped/insulated corny with false bottom, etc? Heat the water in the main vessel, sparge with the sprinkler, etc? A corny is 9" in diameter, and so is this unit What about a bottom drain with QD for easy removal and cleaning of the mlt?

I think with this volume I can get away with wrapping the vessel on the outside with 3/8" copper. Kind of like a non-immersed immersion chiller . Then, I'll put reflectix around that to package everything nicely and get more efficiency out of the element.

I wonder how much volume you would displace if you put the copper coil in the vessel, or how hot you could get it if it was on the outside? You could use it as a Herms coil and recirculate the mash though a cooler, maybe 5 or 7 gallon. Then you could also use the coil as a chiller. During chilling you are going to get condensation on the copper coils, so I'm not sure you want to insulate it with reflectix.

Maybe I could just put reflectix on the inside of the walls, keeping a space between the coils. It's still going insulate quite a bit due to the reflected radiant heat. I'm not too keen on the coil inside because of cleaning and especially displacement, as you mentioned. I'd rather not further reduce my batch volume.

Also, I already have a nice bucket heater, just like this one:


I originally figured I would install an element, from the bottom pointing up. But then I'd have to keep it covered with liquid. And an exposed element at the top could be dangerous.

With a drop in element like this, I think it'll be safer and more tolerant of a half full vessel (in case I might use it as a HLT). Not sure how its 1000w element will work, but I HAVE gotten 10 gals up to 160f in an uninsulated keg on a cold day....it just took some time.

An added benefit is that it has a SS shield, I was worried about melting hop bags in such a narrow vessel.
