My eHerms setup recently made it to the front burner and took priority over my other projects. IN the past month it went from a bare stand and some 15 gallon stainless containers to a completed Igloo cooler MLT, a 5500 watt MLT with a DIY sight glass, a stand with a water filter setup, a 1500 watt, 2-gallon eHerms, and a large collection of small parts, including the PID and one SSR. Between Friday night and now I've also ordered two 40A SSRs, two more heatsinks, 2 30a dryer cords and outlets, the estop switch and two probe type K thermocouples. I plan to use the one PID and switch the thermocouples and SSRs being controled.
This thing started as an exercise in building a really low bucks eBrewery and control panel but will end up taking a lot more money to complete than I would have guessed. All the fittings are brass, the plumbing will be rigid copper or copper/cpvc. When it's done I'll add the costs up and never share that info with SWMBO.
Tomorrow I'll run the 240 line and wire up the spa panel and 4-prong outlet.
