I've read a fair amount about heat stick builds and wiring, especially the big mamma jamma thread called Heatstick = Awesome!
I still have a couple ground questions to which I've not found an answer.
When building a heat stick using a chrome plated brass pipe, is it better to mount the ground in the brass pipe above or below the water/wort line? The Cedar Creek guy shows to do it below the water line, but I've seen others do it above. Is there an advantage or disadvantage to each?
Also, i'm planning to use these to supplement my burner in my keggles. Do I need to worry about grounding issues if using these in the stainless steel of the keggles? For example, I thought I read that the brass pipe should contact the keggle somewhere, but in my set up this won't necessarily happen (I was going to build a PVC joint at the top that would allow it to hang from the side of the keggle). Would that be a safety risk?
