I just got it delivery so I haven't taken the time to fill it full of water. Temps are below zero right now in Minnesota so dumping 20 gallons of water takes a bit more work than normal
Hopefully this weekend I'll find time to fill it in the next couple of days using my other pots and sight glasses. Once I do I'll post up with the results.
I hear you on the cold--I'm not far from you. It's supposed to be close to 50 by the weekend, though.
Just to save you from wasting all that water and time...when you get a chance, could you post the inside dimensions? I'll calculate from that. There's not much of a rounding around the bottom edge, so a simple cylinder calculation should get me fairly close on volume.
Looks like a rock-solid kettle. It's on my Amazon wish list. For $115 shipped, I'm close to pulling the trigger.
