The man is correct. I went from 4 batches a tank (including strike and sparge) to more like 7, possible 8 (don't really pay that much attention).

My chimney only extends up two inches above the bottom of my pot. My logic is that retains most of the heat while keeping the handles cooler. I don't have a picture but mine was from an old metal desk (18 ga steel?) that was left behind when I moved in. I cut a rectangle out, wrapped it around the stand, clamped it temporarily, and pop riveted it together. Voila! Double the amount of brewing on a tank...

Mine has been going strong for two years now. Kinda rusty looking now bout otherwise good. One of the best and cheapest mods for your turkey burner for sure.

I'm guessing those that build heat shields don't have thermometers on their kettles? I don't want to overheat mine, and was thinking about using a half circle heat shield instead. I figure keeping the wind from stripping heat is almost as good as trapping all the heat against the kettle.

Will do. But, could be a bit till I get it going. I was thinking of a heat shield that just sits on top of my flat burner. I could take it off during the mash if I needed to crank the burner.

This is pretty much exactly what I was thinking of doing. But, I might make mine a bit taller. I have a tall narrow kettle. I'm going to keep my eyes open for something I can "re-purpose" for this before I just buy the flashing. And with a rivet gun, I can piece two smaller pieces together. Hmmm, I've got a couple old "road" signs that were left at this house when I moved in....

BTW, the flashing I've seen is galvanized. Isn't there a problem with heating galvanized metal? Gives off deadly toxic fumes?

Reason: more information

Or, you could go with a full circle heat shield for the pot, and a half circle heat shield protecting your thermometer. Small piece of metal, a pair of snips, and a couple more rivets FTW.
