Thanks for the response. The outlets in my planned brewery area aren't wired yet so I will just get two GFCI outlets for them. I was just hoping to cut costs a bit, but proper GFCI protection is worth a little extra money.

Sorry if this has been covered...but what is it like brewing with this indoors? Do you have problems with condensation? Do you need a lot of air flow?

I brew in the kitchen without any extra ventilation; never had any problems with condensation. But then I do have 9ft ceilings, and air in my house is pretty dry (under 30% humidity), so it just acts as a giant humidifier. It's not much different than stovetop brewing in terms of humidity.

Condensation? As long as you're not brewing in a especially tiny room, it's fine. The people who really run into problems are running much bigger rigs and bigger batches, with a lot more boil off and evaporation.

sorry to revive an old thread...but I am having problems understanding exactly why the contactors are necessary. Why couldn't I just place the power switches/buttons between the PID and each SSR and leave out contactors? or even between the SSR and element? Are they really needed? i have been reading around quite a bit and just don't seem to understand. Thanks for the help

Which diagram are you referencing? A link would help a lot.

hey thanks for the quick reply! I am planning on using the 2-element 120V diagram from the first post in this thread

Ok, got it. The contactors are in place due to the fact that the switches involved cannot handle the current draw to drectly energize the heating elements. The elements draw 17A and the switches wanted for the original design cannot handle that current draw.

It is all about design choices for the person wanting to do an E-Brew set up. Generally they spell it out and I take the time to draw a diagram to help them.

Okay thanks P-J! That makes sense now. Thanks for everything - I've learned a ton from all of your diagrams (and I'm sure everyone else has too!)

P-J,

I'm still looking to start my dual 2000w control panel, hopefully soon.

I'll be honest, I'm not hooked on any particular design, I just want functionality. That being said, if the contactors are there only because of the choice of the pushbutton switches, do you have a drawing that uses switches that can handle the load going to the elements, which if I'm understanding correctly, eliminates the need for the contactors? Seems as though that would free up space in the control box and simplify the wiring.
