    How high up the keg is your HERMS coil upper fitting?

    I know this is probably very trivial, but I need to drill my upper hole for my HERMS coil fitting. I can't decide if I should drill it higher or lower. See the picture for reference. I am split between those two spots for the "Out" fitting. I know it doesn't matter much, but help me decide...

    Check out these sanitary welds

    After paying $100 for a crappy weld job from a "professional", I decided to have a buddy tackle the job instead. The "professional" did an OK job...he sort of back purged, and almost got the fittings on straight. There was a very minimal amount of sugaring. However, check out the work a good...

    Stainlessbrewing.com 1/2" HERMS coil??

    For anyone who has the 1/2" 25' long HERMS coil with 90 degree bends at both ends... Can you please tell me what the height distance is between the inlet and outlet? I need to drill holes in my keg and won't have the coil before I need to drill the holes. The website says 5"-6", but can...

    Colorado (4) Brand new 2pc 1/2" Stainless full port ball valves - $28

    I accidentally ordered too many of these, and the return shipping isn't worth it so I'm just trying to recoup my costs and pass them along. Got great pricing by ordering a bunch at once. Four brand new 1/2" 316 stainless full port 2 piece ball valves. Brand new. $28 plus shipping. I can ship...

    Diameter of 1/2" male cam lock

    What is the outer diameter of a 1/2" male cam lock fitting? I'm trying to get some vinyl caps for them, and the searching I've done online has come up with two different numbers. I've seen ~0.9" and ~1.3". Can anyone tell me? Thanks

    Best/preferred location for HERMS fittings on keggle

    I'm about to drill the holes for my e-HERMS HX in and HX out on my HLT keggle. I already have the sight glass and temp sensor, heating element, and drain valve done. However I can't figure out the best spots for the fittings. I also just ordered my coil, which is a 25' long 3/8" SS wort...

    Pressure Drop / Head Loss for 1/2" and 3/8" tubing plotted for tubing length

    I'm just finishing up my very long project of building an all electric, arduino and processing controlled brewery. I'll eventually make a big post about it, but for my next planning phase I am ordering the tubing for my HERMS coil. I read a lot about the debate between 1/2" and 3/8" stainless...

    Is there a reason most people don't run kettle heater and MLT heater at the same time

    So in designing my brewery I am going to use a 120V heating element for my e-HERMS and sparge water, and a 240V element in my boil kettle. I was assuming that I would have the ability to run both of them at once (using a separate wall circuit for the 120V heater than the 240V supply). I noticed...

    Is current through each "hot" leg of 240V half total?

    I searched through as many old threads as I could read and couldn't find this. If I am running a 5500W 240V heater and want to control it with a SSR on one of the hot legs, does it have to be sized to handle the total current flowing to the heater, or is the current through each hot leg half...

    Will extended foil on starter allow mold growth?

    So I tried to harvest Orval dregs, and stepped it up too quickly. Regardless, I covered my container with aluminum foil and had it on a stir plate. For the first few days there was very little activity, then I started seeing some yeast growth. After a few days of seeing stringy yeast floating...

    Which pump would be better?

    I am buying a cheap china made pump to set up my e-HERMS system. I know I should spend more for a better pump, but I'm curious to see if it will work, and the pumps are only $26 and $30. Money is tight, and I think these will work fine. I've searched the forums and can't find anyone using either...

    1lb honey, gravity didn't change??

    So I was brewing an Irish Red the other day, hoping it will be ready for St. Patty's Day! :D I forgot to add honey and after I added it, the gravity was the same and/or possibly lower....?? Brewing went smooth. Hit my pre-boil volume and gravity exactly. End of sparge runnings were 1.02 I...
