Do you notice a difference if you put the output of the mash into the bottom part of the herms compared with starting at the top of the coil?

Yes, the coil is nearly 45'. Through testing I found going in the top reduces the head pressure and increases flow through the coil.

thanks. I have been doing the opposite, like kal, but I always thought top down made more sense.

I think it makes better sense for two reasons-

1. In my case coming in the bottom adds another 45' uphill climb for the pump.
2. I heat from the bottom up so from an efficiency stand point it makes sense to add wort from the top down. Kinda like a counter flow chiller.

Hi Max. May I ask where did you get the 3 boiling kettles?

Are you referring to the keggles?

Used kegs are getting hard to come by around here. It took a while to get these together gathering the parts and getting the couplers TIG welded in. Most of the hardware can be found at vendors here on this site. I've seen kegs on eBay with tops cut, valves, sight glass etc. Nice thing about a keggle is they are heavy duty and can take a serious beating.

I’ve made some changes recently and thought I would update this thread. First I had been working on finding a good way to cool both of my new fermenters and planned on using a Perlick line chiller I have with immersion coils and a manifold. I had Glacier Tanks manufacture custom lids and added additional 4” tri-clamp openings to accommodate the coils and also make it easier to dry hop and knock out. While I was waiting for the lids I came across two, True GDM-26 refrigerated coolers with glass doors. I found them on Craigslist and they were listed as inoperable but in good condition. I made a low ball offer because I was not sure they would fit and the guy passed. I got to thinking about using the immersion coils and the fact that my shop where the fermenters would be is not conditioned all the time. I decided I would look into building a custom walk in box and use the Perlick chiller. In the meantime the Craigslist guy called me and said he was moving that day and if I wanted the coolers come and get them out of his garage. I dropped what I was doing and went to get the coolers and the guy thankfully accepted $200.00 for them. I was happy but a little worried the fermenters were not going to fit. First thing after unloading from the truck we measured them and…they fit! Next I started digging into them to see what was wrong with them. I plugged them in and the circulation fans worked but neither compressor would run. They were apart a little hacked and parts were missing. Thinking the worse I decided I would abandon the compressor/condenser and use the Perlick line chiller to pump antifreeze through the existing evaporator coils to cool the fermenters and abandon the condenser/compressor in the GDM-26’s. My HVAC buddy stopped buy a few nights later and over a few brews while talking about the coolers and decided to play around with them. Long story short I got both units operating and set up on 5” casters for another $300.00 total. This was less than the cost of two immersion coils, associated manifold and plumbing so it was a home run. So I could get brewing I tied the True cooler to my BCS automation. I wrote a few processes for the coolers on the BCS and I have multi stage fermentation schedules for ales and lagers. Glad to share my BCS process programming if anyone is interested. Here are a couple shots of the coolers and test fitting.
