I found a manual from Braumarkt for their Arsegan. File says too large for me to upload, but it looks like a Guten, and operates like a Guten, so it must be, right?
Tried 3 meters of helix coil in the 40 litre Guten today emptied the kettle at 21 C. Emptying worked really well got my forecast 21 litres into the fermenter. Just have to live with the loss to trub.

What's the coil look like in an empty kettle?
That's at 4 meters, looks neater at 3.

Slightly improved jacket for the 70lt guten. Can see the full sight glass now and also got some insulation from some old air conditioning pipe to put over the recirc pipe.
I'm interested in how you guys do your sparge with the guten. The first brew I did I just lifted the malt pipe and ran the sparge water through very quickly. Second brew I held the malt pipe and slowly lifted it over 40minutes so the water moved through slowly. This was very painfull process as I forgot to refill my beer before starting. I am thinking of some sort of whinch setup which I can slowly lift the malt pipe with. any suggestions?
I've been told that a slower sparge gives better efficiency. Is this true?
There are different thoughts, I believe it does others will say just pour it onto the grain bed.As you have the 70 litre that will be a long sparge. With my 50 litre and the hoist I have been thinking along the lines of a batch sparge, instead of 'no sparge' because of the higher volume of grain in the mash.

You held the malt pipe for 40 minutes, that's just showing off!
Doesn't the 70 litre have multiple steps on the malt pipe? Why not lift to the first, sparge a bit, lift to the second, sparge a bit, etc.

Did that the first brew I did and Had low efficiency. I had a mate with me who has done 3v ag for many years and he mentioned that a slower sparge was important. Pretty easy to do with a 3v System but painstaking on the guten. I have only done 2 brews so far so don't know if the slow Sparge is the reason for the better efficiency or if it was just luck. from what I have read and been told it makes sense to keep doing it. Trying to find a way to hook up an electric winch or something to lift the basket slowly And not have to hold it for so long.

Interesting reading weal. I don't know a lot about the different sparge methods yet but how will you batch sparge With the guten? I thought a batch sparge you had to drain the grain bed and then refill with sparge water and drain again.

I have the 50L guten elevated and add 30L of 75deg water and slowly sparge into a keg. When i have the desired volume or get a gravity low enough to stop, I stop, Lift the malt pipe (a lot lighter as not as much wort in there) and pump the wort back in and start the boil. Takes longer, but it’s a balance between getting the efficiency or shortening the brew day?!
As 2095brewer states is what I am going to do.

Did my second batch in the 70L today.
I added a 1m helix for this batch, seems to fit alright.
Not much colour makes it in to the sight glass while the pump is running.
As soon as the pump is stopped this is all that ends up in there @wide eyed and legless
Helix did a good job.
It flowed great for most of the first cube, but was quite slow near the end of the second one.
My telescopic overflow pipe broke after removing the grain. It was super flimsy and the tiny spot welds weren't enough to hold its own weight. I'll call KK tomorrow but I might have to get a bolt and block it up.

Mine broke last weekend as well. Spoke with kk and they sent me a new one no questions asked. I had the same with the sight glass. Clear when mashing and then noticed the bottom half had colored after the sparge pushed more water in.
How important is the overflow pipe? Is a stuck Mash a common thing?

I've never had a stuck mash, but I like the insurance of it.
Today I had to go out and refill my co2 while it was mashing so I set the pipe to 15mm or so above the wort and had no worries.
I've been doing no sparge so I am usually quite close to the handle holes anyway.

I think if you change the Tee piece to an elbow you will get a little extra wort by pointing the elbow at an angle downwards, fit a capillary blank on the opposite end, those Tee's sit too proud out of the wort.
How did the sight glass break?
I really think you would be better off without one, nothing wrong with a piece of dowel with increments marked on it.

It was the telescopic overflow pipe that broke. The height adjustable one attached to the bottom screen of the malt pipe.
I was thinking of getting an elbow and putting the bazooka on the other end to cap it off.

It's just a safety feature. The good thing about a telescopic overflow is that you can set its height above the grain bed to just a little less than the distance between the bottom of the unit and the malt pipe, then you'll never run the risk of a burnt dry element - as it'll never accumulate more liquid on the top than comes out of the bottom
I lost a few parts to my overflow pipe so was keen to get the telescopic one, but these reports of broken welds is a bit worrying. I had a badly scorched element after brewing a hefeweizen with my overflow blocked up, probably could have been avoided with more rice hulls, but a telescopic overflow would have helped too.

Another bloke on FB said his broke as well, I think it will be very common.
They look to have a few little spot welds at the bottom but it just isn't enough. Hopefully the replacement they are sending me is better.

I've been following this thread for a little while now because I'm tossing up between Guten 70L and Brewzilla 65L. Good to see the helix did the job for you. How liters of wort/trub was lost on dead space after filling your cubes?
I borrowed my mate's brewzilla 65L on the weekend and the overflow pipe is screwed into the bottom screen of the malt pipe. Seems a bit more solid than the welds.
Also, really curious about the Guten immersion chiller. Has anyone here used the immersion chiller that comes with the 70L Guten? Does it reach all the way to the bottom and would you be able to chill a single batch? The problem with the brewzilla 65 chiller is that it doesn't reach to the bottom and as a result you can't efficiently chill a single batch with it. The in and outlet also don't hang over the edge of the kettle so all together it's a stuff around trying to use the immersion chiller that comes with the brewzilla.
Bit of silicone tube inside the stem (original version) the bazooka over the top just have the top of the silicone tube peeking over the top of the wort, just in case. If you know where your level is each time it is easily adjusted, full volume mash is always the same level or there about's grain bill dependent.

What you see in my previous pic is how much I left. Probably a litre or so after tilting it to make sure I filled the cube.
That was for a Dark Mild so not a lot of hop matter to filter out.
This pipe has a thread welded on the bottom with a nut on the other side of the screen.
I think the 65L zilla is the same as my old Robo Gen 2 where the thread is machined in to the pipe? Definitely a stronger solution.

Checked mine it's about an inch off the bottom, might get closer with some water in it.. It's quite large I don't see why it wouldn't do the job.

Due to postage issues I haven't received my replacement extendable overflow pipe and have been waiting to brew. So necessity being the mother of invention I started thinking of ways to make another overflow pipe. Had pulled apart of 50lt commercial keg recently and found that the spear from that with a couple of taps with a hammer fits perfectly over the collar of the broken extendable overflow pipe. It's not extendable but fills the hole in the bottom screen and doesn't brake when stirring the grain. works for now.

Hey guys. My pump got blocked after last brew. I tried percarb and hot water. Running the hose through it and It still wouldn't pump water. Pulled it apart today and found a Couple of little pieces of Crap where the magnet is which must have jammed it. After putting it back together the pump works fine but I now have a vibration coming from the pump. If I lift the guten it stops but when sitting on the ground it vibrates. Has anyone had this before? Any idea what might be wrong. All screws seem to be tight. Thanks in advance for any advice.
Never heard of that, seems quite odd.

Is it just a wire vibrating against the body?

Had another look inside and it was a loose screw on the pump. Only thing is I didn't touch that screw. Looks like the little nut on the bracket which the pump screws to was broken during construction and came loose when I moved the pump yesterday. Seems to be holding good for now. No vibration. Might have to get some other nuts to put on the screw so it doesn't happen again. Thanks for the help guys. Brew #5 this Saturday. Loving doing all grain and the guten is performing really well makes AG brewing relatively easy for a beginner.
