I am also looking at a King Cobra since my current IC is rather tall. How are people with the KC suspending it in the wort? Are you hanging it from the pulley or getting a custom bend so it can just sit on the rim of the kettle?
I am not convinced you need a second whirlpool. The only scorching I got on my element happened when I had a defective element with a hot spot, and one other time when I over-pumped and exposed it. For the boil, I run 100% power up to 207F, then cut power to 55% for cruise. (5 gallon batches)
More movement can't hurt but I don't want to give up my sight glass.
First brew on my 20 gallon Nano Brewer Home is complete. Yay!!!

I was very surprised with how easy brewing is on this system. A couple notes from my brew day.
1. The first snag I ran into was getting the basket full of grain off the pulley. The frame was set so the sides sit on the ground at the same level as the feet, so the bottom of the basket is about an inch below the rim when raised. Luckily, my wife was nearby to put the lid on as I lifted the basket and the I set it on the lid and disconnected the pulley. How high do others have the frame off the ground?
2. The whirlpool worked great even with an IC. The problem I had was trying to get all the hop material out of the kettle. I just kept adding some rinse water and trying to get it to drain out the pickup. My guess is that I need a hop basket.
3. My efficiency ended up being about 48%. My guess is the crush. This was the first time using my new Monster Mill and I set it to .045 inches (I took a feeler gauge and put both the .022 and .023 together and used that to size the gap). Not sure what my LHBS mill is set to, but my grain today did not look as crushed as theirs.
Regarding CFC vs IC, I went IC because there is practically no cleanup and I avoid all worries about clogging. I started with a nice plate chiller that worked very well but I was always worried about how clean it was inside and trying to prevent clogging.
I don't understand your first question so I'm no help there.

I don't get what downsides there would be with counterflow vs immersion chiller... as i see it, counterflow chiller is not needed to clean at all.. simply just circulate boiling hot wort through it a few minutest before starting to chill.. then it is sanitized....
After cooling and wort is transfered to fermenter, simply just circulate fresh tap water through it - and if you are paranoid, hot PBW.
I changed to a counterflow chiller, because there was alot less cleaning that immersion chiller - and it is always mounted to my brew-bench.
By the way, on my system which is essentialy the same i have both sight glass and whirlpool tube, and i love it..
Also i have now tried ONE brew with my new basket, which uses 600 micron mesh at bottom... seems alot better than the old 400 micron i had.
So now i have tried them all - 400 micron mesh sided, 400 micron solid sided, 600 micron solid sided. The 600 micron is the winner... 400 micron mesh sided does have great circulation, but efficiency is not very good. 400 micron solid sided does have circulation issues.
What is everyone using to chill their 20 gallon Nano Home? I have a Jaded Wasp immersion chiller that worked well in a smaller kettle but it's taking forever to get 6ish gallons to a reasonable temperature using ground water (I usually give up around 80F and let the ferm chamber finish it off). In a 5 gallon batch only 3/4 of the chiller is submerged and the element gets in the way. I tried using a counterflow chiller on one batch but didn't like it due to cleaning/sanitation concerns and added complexity. I'm curious how everyone else is getting their wort to pitching temp.
Why do you think the 600 which is a tighter mesh has less circulation issues. I know its experience for you but IM curious why that would be. truth be told I cant figure out exactly what or what combination of things have allowed me to dial mine in. I just know its working and am done fiddling with that part of it![]()
Ive considered a CFC becaseu it can be permanently mounted. I do like that idea. I had my IC before though and it works just fins. Cleaning it involves rinsing it after I pump to the fermenter whiles its hanging in the kettle so cleaning it is not an issue at all. I don't make many high gravity beers. Most of mine are 6% or less. That said I have never had a stuck mash in my 400 micron hard sided malt pipe. I have simply found ways to over come it with a few minor mods. I also haven't had a scorch at all since going to a ULD ripple and running the whirlpool during mash and boil. Why do youthink the 600 which is a tighter mesh has less circulation issues. I know its experience for you but IM curious why that would be. truth be told I cant figure out exactly what or what combination of things have allowed me to dial mine in.

Yeah, as said above 600micron is larger than 400. 600 does still give clean wort, but with alot better flow. Sparging could take 1h in worst case for me before, now flow is very good then also. And i only have one brew with it, but it was never close to stuck. I can also say that i usually go for almost a full kettle, and most often OG of 1.06 - 1.075. With the 600 micron i wouldn't think a >1.100 imperial stout would be any trouble at all. I can take pictures of my system later.
