Hey guys/gals, in desperate need of a plumbing schematic for my new EHERMS setup

[dandanbeer]

As stated above, I am in desperate need to an existing schematic for the EHERMS setup I have. I have done so many sketches I feel like I'm about to lose my mind. The least number of 3-way ball valves for the design is currently at 5, given the way I'd like to do it. This is what makes it tricky.
I have no desire to use a plate chiller given my local water supply's levels of calcium in the water. The amount of beerstone I have to deal with is pretty heavy and the amount of maintenance to flush it out is a little more than I'd care for. I'd like to be able to use the HERMS coil to do the chilling.
I have the pretty standard 3 keggle, single-tier, 2 March pump setup with camlocks. That's pretty much it. Anyone else do this or know of a previous thread that I can look through? Maybe one with a nice manifold design to keep it all in front of the kettles?
Thanks and Cheers!

Using the HERMS coil to chill is VERY time consuming based on what I have read,,,

I seriously considered it when designing mine.. I run a single pump & a lowered MLT... Two tier.

That being said, if I had two pumps I would do the following...


1) Strike water heat, recirculate mash water through HERMS, single pump. The second pump to recirculate the HLT heating water..

2) Mash recirculation; One pump recirculating the wort & the other pump recirculating the HERMS heating water. This will greatly increase heating & ramp efficiency.

3) Sparge; One pump from HLT to MLT, Second pump from MLT to brew kettle..

4) Whirlpool on the kettle... I would put two inlets on the kettle & run the two pumps in parallel... You would also need two drains. I doubt one 1/2" fitting will provide enough flow to feed two pumps.. I have never tried it so don't really know... Possibly a single 3/4-1" into a twin 1/2" T ??

Look at the manifold johnw made here on the first page. https://www.homebrewtalk.com/showthread.php?t=204705... I am planning on doing something similar with 6 2way valves and 2 pumps. One pump is a water pump and the other is for wort. I plan on using an IC with a pre-chiller while whirlpooling in the bk. Let me know if you want more info... typing on a phone is its own reward

I though the bcs462 only had 8 control ports. By my count on the above setup for johnw there are 6 electric valves and 3 temperature probes. How is this possible?

Nevermind. Should have googled first.
The BCS-462 interactive temperature controller
8 temperature inputs
8 discrete inputs
18 discrete outputs (6 PWM)

It has 8 inputs, 12 outputs.
