With all that being said, why can I easily boil 6.5 gallons of H2O in an AL pot? AL is the better conducter and should be losing a ton of heat thru its walls. Yet it boiled the water impressively.
I do think JKarp is right: pot geometry has a large effect. You could not boil with an element in a pot that is 5' diameter by 3" deep; the convection would never occur. I think I'll leave it in the the AL pot until I go 220V. Anyway, I am still happy with the fact that a 5 gallon batch can be boiled with 120v..... we do agree on that right?
Glad to hear you are successful with your setup.
