 And do you risk damaging anything by running it at a lower voltage?
No

PEX is the way to go for plumbing. RV tubing would be more appropriate for a hose.

In numbers it goes like this:
4500w / 240 (rated voltage) = 18.75 Amps (current at rated voltage)
240v / 18.75a = 12.8 ohms (this means the element is 12.8 ohms fixed so all other voltages applied can be figured out around this.

120v / 12.8 = 9.375 a given the new voltage.
120v x 9.375a = 1125 watts.

Let's say your grid is actually running 111v:

111v / 12.8 ohms = 8.67a
111v x 8.67a = 962 watts actual

Thanks so much for the explanation.

Did the first dry (wet) run tonight. Things went pretty well. Using my Thermapen I had to adjust the controller by about 1.5 degrees. I've attached a quick video. I still need to mess around with the controller a bit I think. Brew day is going to rock this weekend!

That is awesome! I sent you a PM to see if you have more detailed pics of the inside to assist me with my build

I also would be interested in detailed pics of the inside, or even your wiring diagram. Thanks

Hey guys, I'll try to get something put together tomorrow. I was planning on doing it today but was way too busy

1 thing I have found so far is that I think I'll need a heatsink on the SSR, it did get a bit warm. I'll be getting this done before my weekend brew.

I tried to draw something up, think I got it right. Hope this helps.

Also tonight I installed a heatsink on the SSR I was able to keep everything inside still. I'll have to monitor it this weekend to see if I'll need a fan.
