Does output rate change between heads hearts tails? Guessing no cause mac says dont touch the rc...

If his lph alcohol output doesn't change how can cooling water be affecting it? The reflux in the still is governed by the power input and the rc cooling. If the power stays the same but the cooling warms up there will be less reflux yes but only because the rc will be letting more vapor past it just like turning the rc tap off. I just don't think warm water would be enough to have this affect unless it is really warm, if I'm running on 2400w I need to have my rc nearly off (1/4 of a turn on a gate valve max) before I get any output to my parrot.
But in saying all this maybe his lph have jumped a bit without him noticing it?
Are you having to adjust your rc all the time through the run?
I would be checking my plates for leaks first as it's the simplest one to test :handgestures-thumbupleft:
I'm leaning towards an unnoticed leak(s) being possible. The LPH of my product is not changing and once my needle valve is in the sweet spot, the flow is steady. No fiddling with the RC valve unless the weather changes significantly. I use the lap timer on my phone to keep track of the flow: 320ml mark on my jars take about 8min normally (2.4 LPH). I also tried slowing things down to 320ml = 10min = 1.9 LPH. The slower rate increased the ABV, but only marginally and the effect faded after a jar or two. My cooling water last run started at 13C with a few bags of ice. By the end I had used 10x bags, most of the run was around 16-19C, and ended around 22C. All temps mentioned are the general temp of my reservoir, as opposed to the temp of my condenser outflows.

I am working on a 4inch pot column 650mm high that will evolve to plates and eventually will have a 4 or 5 plate drop in core. I’m not planning on using sight glasses just yet, it will come but it’s a commitment I’ll make later on.
Would it be easier to run perf plates or bubble plates blind?
Any advice here appreciated.
