First,,,, the crock pot is not going full bore the 3 weeks time. It warms up to 100°F and turns off for a period.I'm just worried about how a crock pot is not going to overheat and shut off in 3 weeks
During winter I use 4 mini Crock pots in my winter housing for chickens. They are connected to a dimmer switch circuit. I keep the water at (about finger temperature , guessing 60° to 70°F ).. so it does not freeze. December to March each year. Have not burned out any crock pots yet.
I use these mini ones. I like the way the inserts come out for ez cleaning.

well, not exactly,, but have been keeping chickens as pets over 20 years now. Technically,,,,, used in 20th century and 21st Century
