2. Heat up some heat-exchange water in your BK. Heat it up to your desired mash temp., 152 for example. This water you will later use for sparging.

3. Start recirculating the wort from the mash using your immersion chiller sitting in the BK. Wort comes out from the MLT through a manifold (or whatever you use), goes through the pump, then through the IC sitting in the BK, then back to the MLT through the fly-sparge manifold.

4. Sparging: use the heat-exchange water you used in mashing. Pump it to the fly-sparge manifold. The ready wort goes down into a fermenting bucket.

5. Boil your wort, use your IC for cooling it down, etc, etc.





Mashing w/heat exchange through an IC:



Sparging:

I'm liking this. 2 vessels, one pump, one heat source. The Brutus 20 is a cool system but I wanted an electric system and can't get an element under the false bottom.

So you collect the sparge wort in the fermenting bucket and then dump it back into the BK?

Is a March pump strong enough to pull through the MLT, push up through the IC and back to the MLT?

The March technically does not pull anything, as it is not self priming. But it will easily pussh through the IC and to the MLT, I have done this many times in closed circuit cooling.

It is a trade off. If you're using your BK to hold the heat exchange/sparge water, there's no way to use only two vessels( or no config. that my pea sized brain can think of)
I already had all three vessels, so, for me, it was just a matter of a few reconfigurations.

So during mash, you're using the pump to recirc, but during fly sparge, MLT drains via gravity?

Yep, that's the plan.

It's not "true" 2-vessel brewing if you collect wort into a bucket. It's just that the 3rd vessel is temporary and not built into the system. The only downside to this idea is that you have to wait until the entire sparge is done before you can start heating the wort to boil, not to mention all the heat you'll lose while it's sitting around. The other alternative is to move the sparge to a cooler that you prop on top of the MLT so that you're pumping wort to the BK and gravity draining the sparge. That way, you can flame-on the wort immediately and shave an easy 35-40 minutes off your brew day.

What about putting a heat stick into the fermenter while it is filling? Making sure that the stick is off the bottom of the bucket of course.

You could, but now you're adding a temporary heat source to a temporary vessel getting even further away from the idea of a "simple" two vessel "system". Why not build the 3rd vessel into the system?

Why? I don't know. I was just solving the heat loss problem in the collection vessel. I didn't think it through much farther than that.
