This is excellent! I have been doing BIAB on the stove for a little bit now, but am feeling the constraints of space (both in the kitchen and in my 5gal pot!).

Ive wanted to do a eBrewery ever since I came across Kai's site, but it was worried about the huge initial costs (not to mention being a total noob with electricity/wiring). I really wanted something that would let me "step in", but not totally waste time/materials.

Thank you to both P-J and jrb03 for providing a road-map!

I spent a few hours this morning drawing a diagram that should fit your needs.
The entire build should fit in the Auber Instruments Project Box.

I suggest that you also order their External Mount Heat Sink for the SSR.
The RTD temp probe could be the Deluxe version of Liquid Tight RTD Sensor. It is well worth the extra $9 for it.

I'm not sure how you plan on supplying the 12V power to your pump. I show a 120V outlet that can be used to plug in a transformer. (Edit: I did a search on greatbreweh and found their pumps. They ship with a 12V plug in transformer so the diagram is good to go for that as well.)

I hope this is of some help to you.


As always - Click on the image to see a full scale diagram printable on Tabloid paper (11" x 17")



Wishing you the best.

You show resistors in your diagram...how should they be connected??

Does the pump only recirculate when the element is on?

During recirculation is the element on or off? Just trying to get a idea.

The element is controlled by the PID. This means the element will be alternating on/off to maintain the temp you enter on the PID. This is how it's keeps your mash temp perfect.

Recirculating keeps the fluids moving and the temperature even throughout the kettle. It also helps with efficiency.


Keeps asking questions if you need help - not a prob.

Ok I understand the pid but I was more concerned about hotspots but if you limit the flow and recirculate you won't have That problem. Now I just need to find a narrow pot so I can do 1 gallon batches also

So the pump is just turned on via the LED switch on the control box, right? I have a buddy that actually builds control boxes for a living, and I think I might have him help me out with this project. Gotta get some funds together for it though!

Yes. The pump is turned on with an LED switch. The other 2 switches power on/off the PID and heating element.

I've had several requests about my narrow pot. Ive had it for years, and have not been able to find another one like it. It was sold with a basket, and intended for outdoor frying. All the pots I see now are shorter and wider. If anyone finds something like it please let us know!
