It's been 8 months in the making. A lot of dry kegs right now, unfortunately. Our previous propane burner system was unsatisfactory (chronic problems with lighting and maintaining a lit burner, brewing outdoors in Edmonton's winter sucks.)
The rest of the system has not been photographed yet, but here is the idea:
17 gallon aluminum brew kettle, March pump, 10 gallon cooler with copper manifold, 2-tier brew stand. It's inspired by JKarp's system.
We have 7500W of heating power, split between a 4500W and a 3000W element. The elements are controlled by simple switches, rated for 20A and 250v.
We plan to pump from the kettle to the Mash tun, and gravity drain from the tun into the kettle. We will pump to recirculate the mash for Vorlauf.
Here is the control box:
