Is your RIMS 240v?
Is your RIMS 240v?
What do you use to recirculate into the mashtun? A sparge ring, auto sparge, hose, etc?
Btw you have any links or pics of your build. As you may have guessed I am very curious about it.
Hi everyone,
How's all your 2 vessel HERMS systems going?
I've been planning on going this route for a couple of years now. Up until now I'm indoor electric 19 gallon BIAB.
I finally ordered a nice 50' 1/2" stainless coil for my next BK/HLT that will be 25 or 30 gallons depending on what deal I can find. At first I think I'll just use my existing BK as a MT with a custom made false bottom. Right now I'll make due with one pump (march center inlet) but envision eventually using two.
I like what I'm reading in this thread and I think a system like this has a lot of potential and many combinations of mash volume, thickness, no/sparging.
Have you guys seen these videos? A source of inspiration, for sure.

Hey! Thats ME.
That's awesome! I have so many questions considering I'm building a similar system, but not automated.
The first one is, are you still brewing on that? I'm gonna check out your sig links before I ask more...
As far as I understood the process, with these 8 steps it should be possible to brew a beer. In step 5 I add the sparge water while the mash water (is that the correct term?) is still in the pot. So sparging probably works out a bit less effective, but still better than no sparging at all.
In total I would need two vessels, a heat exchange, two pumps and 8 valves.
Do you guys think that this would work out ok? Has anyone (used) a 2V-HERMS?
2v ebiab, 15 gallon kettle, 10 gallon batches,50l kegmenter,, not herms, 3.5-4 hr brew days...Most HERMS systems use a 3-vessel system, but I was wondering whether it's also possible to do it with 2 vessels. I couln't find a lot of info on this. But one needs less valves, just two vessels, but a separate heat exchanger, so it could be more cost effective. A disadvantage is that sparging is harder to do, see the attachment for my idea.

Awesome post, @Wizard_of_Frobozz ! So is the duty cycle what the SSR acomplishes with your PID? So if you had an EZboil from Auber, it seems like you would be able to mess with this power reduction? I guess the PID that you use with your mash recirculation would be set with a duty cycle, and then the boil PID would just be set full blast. Or if you have a nicely sized RIMS tube that keeps your wort velocity in a good range, you don't have to worry at all.
That seems like a valid concern with the RIMS Rocket. I've heard some people on these forums having some issues with the RIMS rocket, but I'm too much of a novice with the electric setups to know if it's the same issues as a RIMS tube. I definitely like the cost of putting together a RIMS tube vs the cost of a RIMS Rocket.
Since you're using a kettle element and a mash recirculation element, did you make the move to 50 amp? If so, what controller are you using/did you build a controller?
I am going to bite my tongue (thumbs, actually) and avoid what I would love to be a philosophical discussion. This has nothing to do with you corneyl... you just lit my fire with the 2-vessel thing which has been on my mind.
So let's help you out... I think 2 vessels is the way to go. All the benefits of multi vessel without a wasted on (the HLT). I think your idea is sound, and as you noted sparging is the only hiccup. The problem you have fundamentally is no third place for water or wort. So you have to make a choice during the sparge:
1. Drain you initial runnings into a bucket.
2. Drain your runnings in into the BK, along with the remaining sparge water.
3. Put all your sparge water into the MLT and drain into the BK.
4. Batch sparge once.
Given these choices, I would NOT do #2 or #4. As Doug said 2 is like a full volume mash. I don't agree it is the same, but you won't get the best efficiency doing this because of course, you are pumping extracted sugars back on to the mash surface. 4 is just plain silly to me. #1 is more manual than I like but you could do a normal fly sparge.
But i see no downside to #3 other than some lost efficiency. Put your entire sparge volume on top of the grain bed without mixing, then drain into your BK until you hit your pre-boil volume. I think that will work well.
Oh boy that was a while ago. Let me admit that I have little experience with HERMs... none personal but brewed with friends who have. In a two element system you have a choice where to put the mash heating element. If you want/need an HLT, it makes sense to use that mass of heat on a secondary level with HERMs. If you can get away without an HLT (which is easier with some advanced controls but not necessary) then RIMs makes more sense as you will heat your wort rather than heating liquid to heat your wort.
Eliminating that third vessel saves space, reduces cost and extra hardware, eases cleaning a bit, etc.
So it’s my opinion... definitely not fact. HERMs is definitely more forgiving than RIMs. It’s a performance/ease balance IMO. Lots of ways to set up systems which is cool!
