Default LiquidFlame's eHERMS Build -need help

Hello,

I'm on my journey on creating my eHERMS system and I've read a lot of great resources and have gotten a lot of ideas. I'm posting my build to help generate answers and ideas for me and to help any other fellow home brewer. I know with all the knowledgeable people on this forum that I'll be in good hands, so I want to thank everyone in advanced for your input and help. Let the fun begin.

I've taken a lot of ideas from A4J, Tiber_Brew, and Kal. I don't have many specifics yet, but I do know that I will be using 2 5500W elements for the HLT and BK, PID's for monitoring temperatures, 2 March 09 pumps, and Blichmann Therminator for my plate chiller.

Right now I have created my brew rig diagrams (with my awesome MS Paint skills) and would love for people to take a look at them and give me your thoughts. One big thing that sticks out at me is if I really need all those ball valves and if I have them in the right spot.


Step 1: Filling With Water


Step 2: Mash In


Step 3: Mash Out


Step 4: Continuous Sparge


Step 5: Cooling


Step 6: Once Temperature is Reached Add to Fementor

I use 3 way ball valves in place of a several of those T fittings. They cost a little bit more but not any differant than buying three separate ball valves.

I've never used a 3 way ball valve. When you open a port is it completely open or can you restrict the flow?

One thing I'd do over if I was starting again is to have a purge valve for priming the pumps. I spend way to much time futzing around with one of my March pumps to get it to prime right. It just didn't occur to me at the time, but one of these days I'm going to do that for my pump on the right side of my stand.

Hmmm. I'll see if I can find a picture. It's just a way to "burp" out the air to avoid cavitation of the pump.

I was just thinking, I don't think I have my chiller setup correctly. Don't I need the pump the output wort through the chiller? Just opening the value won't work will it.

Mine goes BK/pump/chiller/fermenter.

I can't find a picture of the silly valve I'm talking about. I know I've seen them around here, so I must be using the wrong terms to search. When you mount the pump, you put "in" down, so that the air comes up. Some have elbows on the "in" to make that easier. You don't need a ballvalve on the "in" of the pump. Anyway, there is a T- type fitting I've seen to open, to let the air out, and then only wort or water to the pump.

I'd call it a bleeder valve or something.

I have QDs on my hoses to change them around into the HLT/HERMS/BK/Chiller. I don't see that in your drawing, but it makes life easier!

I will be using QDs on all my hoses, but I would like to have everything connected and not have to move any hoses around.
