I've been researching for some time on eBrewery builds and I've decided on a single vessel MLT with a RIMS tube (no HLT) so sparge water will be heated inline. I will have an electrician help me (once I find one) but I want to make sure I get all the necessary parts first.
I'm sure this has been answered somewhere but I can't see to find it.
My question is how does one switch an element from 240v to 120v with the simple flip of a switch? I plan to run a 5500w ULD element in a RIMS tube at 120v when recirculating the mash. When it's time to mashout I will flip the element to 240v to heat the sparge water inline as mentioned. I've seen the idea discussed (which is where I got it in the first place) but I haven't seen it done or how to do it.
I will control the element with a PID controller which I think should be Auber 1/4 DIN PID Temperature Controller.
Any help is greatly appreciated! All of my inspiration comes from this forum and I have to say you guys are geniuses!!
