Cool, idea. I would've definitely tried this except Santa just brought me a plate chiller. As long as your can clean and sanitize the coil it during the boil this seems like a great idea.

Parts list has been updated. Thanks guys for the great suggestions!

As far as chilling through the HLT, I have heard of people doing it, but it seemed to take a long time. From what I understand, the whirlpool immersion chiller chills really fast. Although, I may be wrong...

Your right though, the HLT has a heat exchanger in it, why not use it. Totally makes sense...

Great diagram Corey! Thanks!

I was reading Madgus's build and saw a comment from BadNewsbrewery talking about the on/off switch for the PID. I was wondering the same thing when reading the wiring diagram also. I just figured there was a good reason it was there. After reading their comments, it seems to be a bit redundant. The only thing I can think of is by turning off the PID, the elements are off but you sill have your pump access? I may just remove it from the plans.

Any thoughts?

Yea. I have always found that unneccessary. I really can't think of many situations you would want your control panel on and PIDs off except, like you mentioned, to have access to the pump on/off switch only. I suppose if you find the PID lights annoying when you want to use only your pump(s) then the switch has value. I can't knock it too much as i'm sure there are plenty of additions I have made to my plans that are silly to other people. It's all about preference I suppose.

The way I see it, having the PIDs on gives you information... whether that's the temperature of the water / wort, or just the air temp, it's something. The only valid reason I can see in turning them off is if you don't like the red / green lights looking at you. The element should be turned off via the element switch / contactor so you're not dependant on the SSR.

But... as Smitty says... some folks want to do things the way they want to do things, and who am I to knock them. As long as they realize it's not necessary, the rest is totally up to them.

I thinking that I don't have element switches. Am I reading the plans wrong? Maybe I should change the two way switch to a three way switch? So, have either element turned on or third position, both off. Does that sound right, or am I missing something?

Thanks guys, all of this is a lot of help... Will be removing PID switch.

Correct, I'm only using 1 element in the HLT and propane to boil, so a 2-way works just fine me. But, with an element in both the HLT and the BK, a 3-way would be best. This way you can't even try to have both on at the same time, overloading the 30 amp circuit.

But yes that switch after the SSR and before the element is a 3-way switch in the wiring diagram you have.

You could theoretically have a 2-way switch that was ON/ON to switch between your two elements. There may be a fraction of a second when both are on at the same time, but I'm willing to guess that there will be next to no appreciable load difference noticed by the wiring or the breaker and you'd be fine. Obviously the smartest and safest way to go would be a 3-way with ON/OFF/ON so you have to break contact with one element before engaging another.

Awesome! Thanks guys, that makes a lot of sense. I will change two way to three way and remove PID switch.
