I vigorously stir my water every 5 minutes or so as its coming up to temp, on the assumption that its not naturally going to heat evenly and I need to continually mix it to get a uniform temp. It seems to work pretty well, although when stirred the center of the whirlpool tends to run a couple degrees hotter than the outsides. Am I wasting my time with this exercise? What do you do with your strike water?
Anyone know the physics of how water heats up? I’d assume it be hotter at the bottom because that’s where the heat source is, or maybe hot water rises like air does? Or does the hotter water transfer its heat to surrounding colder water, essentially helping everything heat more or less evenly? I have no idea, and now that I’ve been thinking about it I really want to know. Someone help me.
